The role of the state on the safety of maritime navigation and protection of maritime environment B. Činčurak, L.L.B. J. J. Strossmayer University in Osijek, Faculty of Law Osijek, Osijek, Croatia A. Vasilj, Ph. D. J. J. Strossmayer University in Osijek, Faculty of Law Osijek, Osijek, Croatia ABSTRACT: The improvement of safety, security and efficiency of maritime traffic as well as the prevention of pollution are among the main concerns of scientists around the world. Maritime safety and security are imperatives to the interests of any nation whose borders include coastal waters and ports. Increasing economic activity throughout the world means more ships, more cargo, and more traffic in ports, coastal areas and regional waterways. To ensure safety, to prevent human injury or loss of life, and to avoid damage to the marine environment, and to property a number of conventions has been adopted. Pollution of sea could be caused by harmful effects from the land, air, oil pipelines damages, during marine scientific research, dumping etc. However, the biggest threat comes from vessels. Emissions of oil, water ballast, petroleum, and wastewater are the most common and dangerous. Important roles in the fight against water pollution, especially in preventing environmental catastrophes have international organizations and national legislations. However, international rules do not regulate all situations and problems. Therefore, national states have important role in preventing maritime safety. 1 INTRODUCTION Modern development of international maritime law in part regulating safety at the sea was inspired by safety of human life and protection of marine environment. Safety, in terms of protecting not only the health and lives of people at sea (both crews and passengers) but also the environment, is a fundamental objective of sea transport policy. Safety of ships and navigation as well as protection of human life and property depend on technical equipment of the ship, safety management, education, training and skills of crew, organization of navigation, state of other objects (waterways, ports, berths, cargo gears), efficient supervision of inspection, authority and administration. Ships in operation today are subject to a vast range of regulations and standards covering every aspect of ship construction and operation. A number of incidents over the years have led to improvements in safety requirements. Business activities in sea shipping cause environmental pollution and are considered environmental hazard from the aspect of safety. Pollution of the marine environment means the introduction by man, directly or indirectly, of substances or energy into the marine environment, which results or is likely to result in such damaging effects as harm to living re- sources and marine life, hazards to human health, interference to marine activities, including fishing and other legitimate uses of the sea, damage of quality for use of sea water and reduction of facilities. Main sources of marine pollution are: land-based activities, vessel pollution, pollution from platforms, from air, dumping, off-shore activities. Concerning pollution from vessels (shipping) it may be result of normal operation of ships or from accidents. “The basic principles of the protection and preservation of the marine environment are the principle of prevention, precautionary principle, “polluter pays” principle and the principle of sustainable development.” (Seršić, M. 2003, p. 237) There is a global awareness that safety and environmental protection issues are of public interest. The role of international community (UN and other international organizations e.g. IMO, OECD, UNCITRAL as well as the EU at the regional European level) in legal regulating of these issues is significant. The purpose of the conventions is to raise the level of standards regulating technical and operational aspects of ships in order to reduce safety and environmental protection risks. Legal norms regulating pollution can be divided to: a) norms for preventing pollution, b) norms on combating and limiting pollution and c) repressive norms. 2 INTERNATIONAL LEGAL FRAMEWORK OF SAFETY AT THE SEA, PREVENTION OF POLLUTION FROM SHIPS, RIGHTS AND OBLIGATIONS OF THE STATE Vessels can pollute water in many ways: spills of oil and other chemicals from tankers, ballast water, discharge of cargo remains, sewage are the most important. Ships also produce noise that disturbs natural wildlife and exhaust emissions are source of air pollution. Pollution from vessels (shipping) can be result of normal operation of ships or from maritime casualties. Most frequent causes of maritime accidents are: human error, improper operation and maintenance of equipment, ships age, improper spare parts, the company itself, the management, etc. The major causes for human factor error are: lack of standards, no proper knowledge and experience no plans for emergency situations, lack of information, unclear instructions. With regard to norms and position after pollution has been made, vessel can be submitted to authority of costal state, flag state or port state. Each of these state have certain rights and obligation in application of environment protection regulation. Numerous international treaties regulating these issues were adopted; in this place only relevant for the purpose of this paper will be shown. 2.1 The United Nations Convention on the Law of the Sea The most important global international treaty regulating law of the sea in general but also protection and preservation of marine environment is the United Nations Convention on the Law of the Sea (UNCLOS) concluded in 1982, came into force in 1994. To date, 158 countries and the European Community have joined in the Convention. Provisions on protection and preservation of marine environment are included in Part XII of the Convention. It does not contain detailed rules or specific standards; its provision lay down only general principles and rules, establishing a global framework of obligations, responsibilities and powers of states in all maters of marine environment protection (Seršić, M. 2003, p. 235). Therefore, UNCLOS needs to be complemented with further treaty law structure provided by the IMO conventions and protocols in order to ensure that obligations to implement the extremely precise technical rules and standards contained in such conventions and protocols become binding in accordance with international law. The Convention lays down, first of all, the fundamental obligation of all States to protect and preserve the marine environment (Article 192 of the UNCLOS). It further urges all States to cooperate on a global and regional basis in formulating rules and standards and otherwise take measures for the same purpose. Coastal States are empowered to enforce their national standards and anti-pollution measures within their territorial sea. Every coastal State is granted jurisdiction for the protection and preservation of the marine environment of its exclusive economic zone (EEZ). Such jurisdiction allows coastal States to control, prevent and reduce marine pollution from dumping, land-based sources or seabed activities subject to national jurisdiction, or from or through the atmosphere. (see Articles: 56, 60, 80 and 208 of the UNCOS). “States shall adopt laws and regulations for the prevention, reduction and control of pollution of the marine environment from vessels flying their flag or of their registry. Such laws and regulations shall at least have the same effect as that of generally accepted international rules and standards established through the competent international organization or general diplomatic conference.” (Article 211, paragraph 2 of the UNCLOS). Coastal States may, in the exercise of their sovereignty within their territorial sea, adopt laws and regulations for the prevention, reduction and control of marine pollution from foreign vessels, including vessels exercising the right of innocent passage. “Coastal States, for the purpose of enforcement as provided for in section 6, may in respect of their EEZ adopt laws and regulations for the prevention, reduction and control of pollution from vessels conforming to and giving effect to generally accepted international rules and standards established through the competent international organization or general diplomatic conference.” (Article 211, paragraph 5 of the UNCLOS). According to Article 220, paragraph 1 of the UNCLOS, when a vessel is voluntarily within a port or at an off-shore terminal of a costal state, that State may, subject to section 7, institute proceedings in respect of any violation of its laws and regulations adopted in accordance with the Convention or applicable international rules and standards for the prevention, reduction and control of pollution from vessels when the violation has occurred within the territorial sea or the EEZ of that State. “Where there is clear objective evidence that a vessel navigating in the EEZ or the territorial sea of a State has, in the EEZ, committed a violation referred to in paragraph 3 resulting in a discharge causing major damage or threat of major damage to the coastline or related interests of the coastal State, or to any resources of its territorial sea or EEZ, that State may, subject to section 7, provided that the evidence so warrants, institute proceedings, including detention of the vessel, in accordance with its laws” (Article 220, paragraph 6 of the UNCLOS). On the other hand, it is the duty of the “flag State”, the State where a ship is registered and whose flag it flies, to enforce the rules adopted for the control of marine pollution from vessels, irrespective of where a violation occurs. This serves as a safeguard for the enforcement of international rules, particularly in waters beyond the national jurisdiction of the coastal State, i.e., on the high seas. “However, practice has shown that system of measures of the flag states which derives from such rules is often very inefficient.” (Fabijanić Gagro, S. 2008, p. 415.) Reasons are e. g.: states with flags of convenience ("open registries"), insufficient interest of the flag state to start the procedure and penalize act that happened in far away or in the high seas where “no one is damaged”. Every state has jurisdiction and control in administrative, technical and social matters over ships flying its flag (about duties of the flag State on the high seas, see Article 94 of the UNCLOS. Every State shall take such measures for ships flying its flag as are necessary to ensure safety at sea with regard to: the construction, equipment and seaworthiness of ships; the manning of ships, labour conditions and the training of crews, taking into account the applicable international instruments; the use of signals, the maintenance of communications and the prevention of collisions. Furthermore, the Convention gives enforcement powers to the “port State”, or the State where a ship is destined. “When a vessel is voluntarily within a port or at an off-shore terminal of a State, that State may undertake investigations and, where the evidence so warrants, institute proceedings in respect of any discharge from that vessel outside the internal waters, territorial sea or exclusive economic zone of that State in violation of applicable international rules and standards established through the competent international organization or general diplomatic conference.” (Article 218, paragraph 1 of the UNCLOS). According to Article 219 of the UNCLOS, states which, upon request or on their own initiative, have ascertained that a vessel within one of their ports or at one of their off-shore terminals is in violation of applicable international rules and standards relating to seaworthiness of vessels and thereby threatens damage to the marine environment shall, as far as practicable, take administrative measures to prevent the vessel from sailing. Such States may permit the vessel to proceed only to the nearest appropriate repair yard and, upon removal of the causes of the violation, shall permit the vessel to continue immediately. To ensure proper implementation of this regulations in practice, port states must have capable personnel and adequate equipment in ports (this will cause financial burden for some states) in addition to harmonize rules and procedures in different states. 2.2 The international Convention for the Safety of Life at the Sea (SOLAS The most important of all treaties dealing with maritime safety is the International Convention for the Safety of Life at the Sea (SOLAS), adopted in 1974 and came into effect in 1980. It covers various aspects of ship safety, including construction, fire protection, life-saving appliances, radio communications, safety of navigation, the carriage of cargos and safety measures for high speed craft. The main objective of the SOLAS Convention is to specify minimum standards for the construction, equipment and operation of ships, compatible with their safety. Flag States are responsible for ensuring that ships under their flag comply with its requirements, and a number of certificates are prescribed in the Convention as proof that this has been done. Control provisions also allow Contracting Governments to inspect ships of other Contracting States if there are clear grounds for believing that the ship and its equipment do not substantially comply with the requirements of the Convention - this procedure is known as port state control. The provisions of chapter regulating safety of navigation are mainly of an operational nature and apply to all ships on all voyages. This is in contrast to the Convention as a whole, which only applies to ships of a certain size engaged on international voyages. The chapter also includes a general obligation for Contracting Governments to ensure that all ships are sufficiently and efficiently manned from a safety point of view. Requirements for the fitting of radar and other navigational aids are also contained in this chapter. 2.3 ISM CODE In 1993, IMO adopted the International Management Code for the Safe Operation of Ships and for Pollution Prevention (the ISM Code), that became mandatory in 1998. The Code became applicable, under chapter IX of the International Convention for the Safety of Life at Sea, 1974, first for passenger ships, tankers and bulk carriers in 1998, thereafter for all other ships over 500 GT in 2002. By adding the ISM Code to SOLAS it is intended to provide an international standard for the safe management of ships and for pollution prevention. The ISM Code is projected to improve the safety of international shipping and to reduce pollution from ships by impacting on the way shipping companies are managed and operated. The Code establishes safety-management objectives and requires a safety management system (SMS - a structured and documented system enabling Company personnel to implement effectively the Company safety and environmental protection policy) to be established by “the Company”, which is defined as “the owner of the ship or any other organization or person such as the manager, or the bareboat charterer, who has assumed the responsibility for operation of the ship from the ship owner and who, on assuming such responsibility, has agreed to take over all duties and responsibility imposed by the Code.” (Part A - Implementation, 1 General, paragraph 1.1.2., of the ISM Code). The Company is then required to establish and implement a policy for achieving these objectives. “The requirements of this Code may be applied to all ships.” (Part A - Implementation, 1 General, paragraph 1.3., of the ISM Code). States parties of the Code must form a system certification, verification and control. Certified organization of a flag state issues two certificates: Document of Compliance and Safety Management Certificate. The ship should be operated by a Company which has been issued with a Document of Compliance. Such a document should be accepted as evidence that the Company is capable of complying with the requirements of this Code. The Document of Compliance should be issued by the Administration (the Government of the State whose flag the ship is entitled to fly). “The Safety Management Certificate should be issued to a ship for a period which should not exceed five years by the Administration or an organization recognized by the Administration or, at the request of the Administration, by another Contracting Government. The Safety Management Certificate should be issued after verifying that the Company and its shipboard management operate in accordance with the approved safety management system. Such a Certificate should be accepted as evidence that the ship is complying with the requirements of this Code.” (Part B - Certification and Verification, paragraph 13.7., of the ISM Code). “The objectives of a safe management and operation of the ship as imposed by the ISM Code being a part of the SOLAS convention are the criteria by which a court or arbitration will asses the responsibility of the ship owner in the implementation of the Code. The ship owner will establish his own regulation system and will be obliged to prove that it is being duly implemented. Any failure in this respect on his part can have an adverse effect upon limitation of liability, the rights from marine insurance contract and general average. The implementation of the ISM Code, combined with the required system of control and written reports, practically increases the possibility of the claimant to challenge the ship owner’s right to limitation of liability. Non compliance with the provisions of the ISM Code, alongside with meeting the general prerequisites for a loss of right to limitation (Limitation Convention 1976, article 4) can be taken as a reason for the ship owner’s loss of right to limitation of liability.” (Pavić, D. 2001. p. 70) Besides improvements in the technical regulations, the entry into force of the International Safety Management (ISM) Code was an important step in focusing on the “human element” side of shipping, by providing an international standard for the safe management and operation of ships and for pollution prevention. In implementation of the ISM Code a flag state and port state have an important role, both because of the right to control the ship and to create rules that vessels have to accomplish to enter the ports. 2.4 International Convention for the Prevention of Pollution from ships (MARPOL) The most important convention regulating and preventing marine pollution by ships is the IMO International Convention for the Prevention of Pollution from Ships (MARPOL 73/78). It covers accidental and operational oil pollution as well as pollution by chemicals, goods in packaged form, sewage, garbage and air pollution. While the definition included in UNCLOS applies to all sources of marine pollution, MARPOL regulate pollution from vessels. In principle, MARPOL deals with operational discharges of harmful substances, namely those related to the normal operation of ships. Six technical annexes regulate preventive measures regarding five main categories of substances: oil, noxious liquid substances in bulk, harmful substances carried by sea in packaged forms sewage, garbage, and air pollution. The Convention includes a Protocol concerning reports on incidents involving harmful substances, which apply to incidents resulting from operational discharges as well as from accidents involving a ship. The enforcement of MARPOL relies primarily on the use of flag State jurisdiction in regard to the construction, design, equipment and manning of ships. MARPOL also includes regulations relating to the inspection of foreign ships voluntarily in port, to ensure that they comply with anti-pollution rules and standards and to prevent the ship from sailing if these requirements are not met. Furthermore, MARPOL entitles port States to institute proceedings in accordance with their law. Article 6 of the MARPOL contains regulations on the detection of violations and the procedures to be undertaken by port States. They include detailed requirements on co-operation between the administrations of the port and flag State following the detection of a violation to this Convention committed by a foreign ship. Provisions concerning conditions for the issue of mandatory certificates and the information which these certificates should contain are included in the technical annexes of the MARPOL, that also pro- vides for the obligation of the flag State to undertake not only initial surveys as a prerequisite for the issue of certificates but also periodical and intermediate inspections and surveys, in order to verify that the certificates conform with the actual condition of the vessels. Article 4 of the MARPOL establishes the obligation of the flag State to institute proceedings as soon as possible with respect to any violation of the requirements of the Convention wherever it occurs, in accordance with its law. 3 EU LEGISLATION Shipping accidents are a huge concern to the European Community, and in particular those which cause loss of human life or major pollution in the EU sea areas and along the coastline of the Member States. As there are international rules to regulate safety at sea, the Community's main contribution has been to transpose them into Community law, ensuring they have legal force and uniform application throughout the Member States. In 1993 the Commission launched an action program in a communication entitled “A common policy on safe seas” COM(93)66. This focused on the development, transposition and application of international rules, the training of personnel and the development of infrastructures. The communication “Towards a new maritime strategy” COM(96)0081, confirmed the program. In its resolution of 8 June 1993 the Council approved the program and defined the following objectives: effective and uniform implementation of international rules, enhanced training, improvement of maritime infrastructures and of traffic procedures, legal measures concerning civil liability, harmonization of standards with regard to survival craft on passenger vessels, risk assessment, environmental protection. International safety standards for passenger vessels are applied in the Community. Thus, the SOLAS Convention and the MARPOL Convention are applicable to the Member States and to ships flying their flags (Regulation 2158/93). The Member States must subject cargo ships and passenger ships to initial and annual surveys to check in particular compliance with the SOLAS Convention (Directive 1999/35 last amended by Regulation 219/2009). Passenger ships operating on domestic voyages, which are not covered by the SOLAS international Convention, are covered by a Community Directive, which is intended to guarantee maximum safety for passengers and, at the same time, to provide a level playing field based on convergent standards in Community shipping (Directive 98/18, consolidated version 01.01.2005). In order to ensure that the maximum capacity of ships is not exceeded and to provide accurate information to the emergency services in the event of an accident, another Directive obliges shipping companies operating to or from Community ports to count and register the crew members and persons sailing on board passenger ships (Directive 98/41, consolidated version 11.12.2008). The Community implements the ISM Code (Regulation 336/2006, consolidated version 11.12.2008). Ships using Community ports and sailing in the waters under the jurisdiction of the Member States must respect the international standards for ship safety, pollution prevention and shipboard living and working conditions (port State control) (Directive 95/21, consolidated version 29.11.2002). Member States must take all necessary steps to ensure that tankers carrying oil, gas and chemicals and docking in the Community's sea ports be obliged to respect certain safety conditions. Member States with a North Sea or Channel coastline must take steps to ensure that ships in these areas are piloted by properly qualified sea pilots (Directive 79/115). The Community vessel traffic monitoring and information system aims at enhancing the safety and efficiency of maritime traffic, improving the response of authorities to incidents, accidents or potentially dangerous situations at sea, including search and rescue operations, and contributing to a better prevention and detection of pollution by ships (Directive 2002/59). A Directive strives to improve safety at sea and prevent pollution of the marine environment by improving the safety performance of equipment carried on board and strengthening the powers of the authorised inspection bodies (Directive 96/98, consolidated version 21.07.2008). Directive 2005/65 imposes various measures to be taken by the Member States to enhance port security (Directive 2005/65). The Member States of the EU have agreed to sign, ratify or accede to the International Convention on Civil Liability for Bunker Oil Pollution Damage (the Bunkers Convention) (Decision 2002/762) and to the International Convention on Liability and Compensation for Damage in connection with the Carriage of Hazardous and Noxious Substances by Sea (the HNS Convention), tending to improve protection at international level for victims of marine pollution (Decision 2002/971). A Committee on Safe Seas and the Prevention of Pollution from Ships (COSS) assists and advises the Commission on all matters of maritime safety and prevention or reduction of pollution of the environment by shipping activities (Regulation 2099/2002, consolidated version 01.02.2007). The independent European Maritime Safety Agency (EMSA) assists the Commission with drafting maritime legislation, monitoring application by the Member States and coordinating inquiries after accidents at sea or after accidental or illicit pollution caused by ships (Regulation 1406/2002, consolidated version 31.12.2006). Community legislation, measures and controls have been reinforced following the Erika and Prestige tanker disasters in 1999 and 2002 (the Commission adopted a series of preventive measures, known as the Erika I and II packages). The prohibition and the gradual withdrawing of single-hull oil tankers, the close monitoring and strict enforcement of the implementation of existing legislation, more controls in EU territorial waters and inspections in ports, the partial harmonization of penal sanctions for marine pollution and the creation of the European Maritime Safety Agency are examples of the huge effort which has been made to improve maritime safety in the EU. The Commission adopted a third package of 7 legislative proposals in 2005, to supplement and improve existing rules, particularly regarding classification societies, port state control, monitoring of maritime traffic, responsibility of flag States, maritime accident investigations and liability of shipowners. In May, 2009 the European Parliament adopted a new directive that forces EU countries to introduce criminal penalties for maritime pollution, whether caused deliberately or by negligence. The directive introduces compulsory criminal sanctions for serious cases of maritime pollution, and also forces Member States to impose stringent penalties for minor cases if they are repeated, deliberately caused or the result of serious negligence. The EU law leaves it to national governments to set the penalties, but requires them to be effective. 4 OTHER ISSUES REGARDING MARITIME SAFETY 4.1 Port state control “The basic objective of the port system is to achieve efficiency and effectiveness of the system, high productivity and to realize as well as maintain high competitiveness within the environment. Consequently, the issue of port security and management is the crucial condition of port operation.” (Bukljaš Skočibušić, M. 2008, p. 326) Port State Control is the inspection of foreign ships in national ports to verify that the condition of the ship and its equipment comply with the requirements of international regulations and that the ship is manned and operated in compliance with these rules. Many of IMO's most important technical conventions contain provisions for ships to be inspected when they visit foreign ports to ensure that they meet IMO requirements. The primary responsibility for ships’ standards rests with the flag State - but port State control provides a “safety net” to catch substandard ships. Resolution A.787(19) on Procedures for Port State Control adopted by the IMO Assembly in 1995 contains comprehensive guidelines on port State inspections, identification of contraventions, detention and port and flag State reporting requirements. The guidelines include provisions on the detention of ships. The EU had already introduced, in 1995, a system of Port State controls to monitor foreign ships entering EU ports which allows substandard ships to be added to a Community blacklist and refused access to EU ports. 4.2 Ship construction It is assumed that tourist ships, sport and recreation ships, ferries and fishing ships are not adequately equipped with navigational and protection equipment. It may also be assumed that the crew aboard such ships is not sufficiently trained for conducting those ships. Such ships are more frequent than Convention ships and are more difficult to control. There are differences in skills, required competences and state control which vary from country to country. All vessels should be constructed in such a manner that, if properly maintained, they could remain safe for their entire economic life as well as all parts of a ship should be easily accessed to permit proper inspection and ease of maintenance. An important document regulating construction of the ships is International Code for the Construction and Equipment of Ships carrying Dangerous Chemicals in Bulk (IBC Code). The IBC Code provides an international standard for the safe carriage by sea of dangerous and noxious liquid chemicals in bulk. To minimize the risks to ships, their crews and the environment, the Code prescribes the design and construction standards of ships and the equipment they should carry, with due regard to the nature of the products involved. Carriage of chemicals in bulk is covered by regulations in SOLAS Chapter VII Carriage of dangerous goods and MARPOL Annex II - Regulations for the Control of Pollution by Noxious Liquid Substances in Bulk. Both Conventions require chemical tankers built after 1 July 1986 to comply with the IBC Code. 4.3 Places of refuge to vessels in trouble When there is an incident, coastal States need to be prepared. The issue of “places of refuge” is one aspect of emergency planning in the consideration of which the rights and interests of coastal states as well as the need to provide assistance to vessels that are damaged or disabled or otherwise in distress at sea ought to be taken into account. There is no specific reference to places of refuge in international conventions and no specific obligations on coastal states to provide places of refuge to ships in distress. Nevertheless, it is an ancient principle that ships in distress enjoy the right to take refuge in the nearest port. This right is however no longer absolute and concerns for public health and the need to protect the environment have resulted in some coastal states denying access to ships in difficulty due to the character of the cargoes they were carrying. International law recognizes the right of states to regulate entry into their ports. The right of a foreign ship to stop and anchor in cases of force majeure or distress is explicitly referred to by UNCLOS in the case of navigation in the territorial sea (Article 18, paragraph 2), straits used for international navigation (Article 39, paragraph 1(c)) and in archipelagic waters (Article 54). The right of a foreign ship to enter a port or internal waters of another state in situations of force majeure or distress is not regulated by UNCLOS, although this constitutes an internationally accepted practice, at least in order to preserve human life. This, however, does not preclude the adoption of rules or guidelines complementing the provisions of UNCLOS. The duty to render assistance to vessels and persons in distress at sea is a well-established principle of international maritime law (Article 98 of UNCLOS) and SOLAS regulation V/7 requires Governments to ensure that any necessary arrangements are made for distress communication and coordination in their area of responsibility and for the rescue of persons in distress at sea round their coasts. These arrangements shall include the establishment, operation and maintenance of such search and rescue facilities as are deemed practicable and necessary, having regard to the density of the seagoing traffic and the navigational dangers and shall, so far as possible, provide adequate means of locating and rescuing such persons. By focussing more on human life and safety rather than on what is to be done with the ship in cases of force majeure or distress, these provisions do not of themselves give a right of entry to a place of refuge, nor do they explicitly refer to the question of a coastal state’s obligation to establish places of refuge. On the other hand, neither do they preclude such a principle. In 2003, the IMO Assembly adopted two resolutions addressing the issue of places of refuge for ships in distress: 1. Resolution A.949(23), Guidelines on places of refuge for ships in need of assistance, are intended for use when a ship is in need of assistance but the safety of life is not involved. The guidelines recognize that, when a ship has suffered an incident, the best way of preventing damage or pollution from its progressive deterioration is to transfer its cargo and bunkers, and to repair the casualty. Such an operation is best carried out in a place of refuge. However, to bring such a ship into a place of refuge near a coast may endanger the coastal State, both economically and from the environmental point of view, and local authorities and populations may strongly object to the operation. Therefore, granting access to a place of refuge could involve a political decision which can only be taken on a case-by-case basis. In so doing, consideration would need to be given to balancing the interests of the affected ship with those of the environment. 2. A second resolution, A.950(23), Maritime Assistance Services (MAS), recommends that all coastal States should establish a maritime assistance service (MAS). 5 CONCLUSIONS Pollution accompanies most kinds of human activities and in contrast with land ecosystems, in the water environment, pollutants quickly spread over large distances from the sources of pollution. Main sources of marine pollution are: land-based activities, vessel pollution, pollution from platforms, from air, dumping, off-shore activities. However, the biggest threat comes from vessels. Emissions of oil, water ballast, petroleum, and wastewater are the most common and dangerous. Concerning pollution from vessels (shipping) it may be result of normal operation of ships or from maritime casualties. People get into difficulties at sea for a variety of reasons, including: lack of education, training and/or knowledge; failure to take responsibility for actions; not being prepared for the conditions (water and/or weather) and underestimating the hazards present; not preparing the vessel properly. Despite the existence of a well developed framework of international standards for safety at sea and for the protection of the marine environment (most of them laid down in Conventions developed within the IMO) many flag states and ship-owners continue to break the rules, thereby putting crews and the environment at risk and benefiting from unfair competition. Conventions are particularly important because they are binding legal instruments. A state which ratifies or accedes to a convention is obliged to put it into effect by making its requirements part of its own national law. When implementing rules, the role of the state is very important. In accordance with Article 211, paragraph 2 of the UNCLOS, states must adopt laws and regulations for the prevention, reduction and control of pollution of the marine environment from vessels “flying their flag or of their registry”. Such laws and regulations must at least have the same effect as that of generally accepted international rules and standards (i.e. those contained in MARPOL) established though the competent international organization (IMO). However, practice has shown that system of measures of the flag states is often very inefficient (states with flags of convenience). In additional states are also responsible for technical surveys, issue of certification, inspection, investigation, co-operation in the detection of violations and the enforcement of the provisions, etc. A port state control (PSC) is also important mechanism to promote more effective implementation of all applicable standards for maritime safety and pollution prevention. Port State control inspections are normally limited to checking certificates and documents. But if certificates are not valid or if there are clear grounds for believing that the condition of the ship or of its equipment, or its crew, does not substantially meet the requirements of a relevant instrument, a more detailed inspection may be carried out. It is known that the maritime sector is a global entity and that the implementation of existing international standards varies greatly throughout the world. This is consequently a fundamental problem for any country, or group of countries, which would like to ensure high safety standards for ships operating in, or near to, their coastal waters. Harmonised standards for port State control inspections and common qualifications for inspectors will ensure a more consistent enforcement of maritime rules. Every state exercises its jurisdiction and control in administrative, technical and social matters over ships flying its flag. For that purpose, state shall: maintain a register of ships containing the names and particulars of ships flying its flag, assume jurisdiction under its internal law over each ship flying its flag and its master, officers and crew. Every state shall take measures for ships flying its flag to ensure safety at sea. Such measures shall include those necessary to ensure: that each ship, before registration and thereafter at appropriate intervals, is surveyed by a qualified surveyor of ships, and has on board such charts, nautical publications and navigational equipment and instruments as are appropriate for the safe navigation of the ship; that each ship is in the charge of a master and officers who possess appropriate qualifications, in particular in seamanship, navigation, communications and marine engineering, and that the crew is appropriate in qualification and numbers for the type, size, machinery and equipment of the ship; that the master, officers and, to the extent appropriate, the crew are fully conversant with and required to observe the applicable international regulations concerning the safety of life at sea, the prevention of collisions, the prevention, reduction and control of marine pollution, and the maintenance of communications by radio. (see Article 94 of the UNCLOS). Whenever a maritime accident occurs it is necessary to do everything possible to ensure investiga- tion. It is important to establish a system which enables legal responsibility to be determined and ensures that any compensation owed is paid. Penalties provided for by the laws and regulations of states for vessels flying their flag shall be adequate in severity to discourage violations wherever they occur. International rules do not regulate all situations and problems. In such case, or when a state is not a party of the conventions, the most often its national legislation will be the one that will applicable in case of accident and pollution (generally, coastal states are empowered to enforce their national standards and anti-pollution measures within their territorial sea.). Here is also a great responsibility of the state in protection of the marine environment. REFERENCES Andrassy, J. & Bakotić, B. & Vukas, B. 1998. Međunarodno pravo 1. Zagreb: Školska knjiga.
