Part 3 of this Code of Practice is to be referred to. The responsibility to ensure that the scope and purpose of this CoP is achieved rests with the O.I.M./ Unit Superintendent, it is to be read and understood by all personnel involved in the work. 2.2 OBJECTIVES To perform all work in a manner such as to ensure the safety of all personnel, equipment and the Marine Unit. To maintain safe production and/or offloading of oil without interruption whenever possible throughout the work to the satisfaction of the O.I.M./Unit Superintendent. 2.3 GENERAL (a) 2.4 All hot work taking place in tanks on the Marine Unit will be clearly defined by the O.I.M./Unit Superintendent, appropriate senior staff, and the Safety Officer in the form of a written work scope complemented by detailed attachments, i.e. tank plans, isolations and spading lists, Risk Assessments, marked up P & ID’s and location drawings to illustrate the work scope clearly and unambiguously. The description of the hot work, the written work scope, associated attachments and safety procedures will be submitted to the Production Management Office in Monaco for approval. A checklist (with signatures) will be used to complement the preparations/isolations contained within the permits raised for the work. WORK APPROVAL (a) The hot work procedure will be developed on board and reviewed and approved by the O.I.M./ Unit Superintendent, prior to forwarding to the Shore Base. The Shore Base Unit Operations Manager will discuss, amend as necessary and agree the content with the O.I.M./ Unit Superintendent, prior to forwarding to the relevant Area Operations Manager in the Monaco Production Management Office. The latter will discuss with the FPSO/FSO Engineer if he considers it necessary. (b) The Area Operations Manager and the Marine Superintendent will review the procedure and when satisfied the Area Operations Manager will send it to the HSE Manager, who will in turn, review and comment on the content. -8- 21/03/05 PART 2 - HW IN CARGO AND BALLAST TANKS To perform hot work in cargo or ballast tanks to the satisfaction of the Certifying Authorities.

This "loop" between the aforementioned parties will remain until agreement is reached. Once a definitive Hot Work Procedure is in place and agreed by all, the Production Operations Manager (or his delegate) will officially issue approval in writing for the work to commence. The cover sheet for the Hot Work Procedure will contain signatures of the following, i.e. O.I.M./ Unit Superintendent Shore Base Unit Operations Manager Production Management Office Marine Superintendent Area Operations Manager (review with the FPSO/FSO Engineer) HSE Manager Production Operations Manager (final approval) Any changes in conditions to the approved procedure once work has started, will require the re approval by the persons listed above. Full documentation will be required to be submitted as a revision; an appropriate revision number will be applied to the procedure. GENERAL NOTE Whenever hot work is required in a hazardous area on a Marine Unit, i.e. pump room, main deck forward of the accommodation, turret, or at any other location considered to be hazardous by the O.I.M./ Unit Superintendent, then a procedure must be produced and approved as described in this CoP. 2.6 ORGANISATION AND RESPONSIBILITIES (a) All hot work taking place in cargo or ballast tanks must have an independent Safety Consultant present in order to monitor and supervise this particular activity; this policy can only be waived by the Production Operations Manager. (b) The Safety Consultant will act as the independent safety authority for the hot work activities in the tanks. He has the delegated authority to stop the work or to prevent the start of work if he is not satisfied with the safety of the operation. The Safety Consultant will liaise directly with the Area Operations Manager and inform him immediately of any breaches to this procedure, or at any time he has concerns relating to the safety of the ongoing work. (c) The Safety Officer and the Area Authority will keep the O.I.M./Unit Superintendent fully informed. The Safety Consultant shall be party to the daily progress meetings convened for this purpose. The work programme will normally be carried out in daylight hours. If time constraints are imposed i.e. a job window is applicable, working at night may be necessary but this must be assessed and risk assessed in the planning stage. (d) The hot work will be continuously supervised by the Safety Consultant who may be relieved by the Safety Officer, Area Authority, or O.I.M./Unit Superintendent during meal breaks, handovers etc. -9- 21/03/05 PART 2 - HW IN CARGO AND BALLAST TANKS 2.5 CODES OF PRACTICE AND OPERATING PROCEDURES MANUAL PART 1 - GENERIC CODES OF PRACTICE OFFSHORE HOT WORK PROCEDURES PART 1 PART 2 PART 3 00 HW IN HAZARDOUS AREAS – APPROVAL AUTHORITY LEVELS HW IN CARGO & BALLAST TANKS GENERAL HW IN HAZARDOUS AREAS 07 90 029 ISSUE 01 REV. 01 (e) The organisation and responsibilities of all concerned are to be agreed and clearly defined before operations are commenced in order to avoid omissions and confusion. (f) The agreed work patterns are to be maintained and no work is to be contemplated or undertaken without full discussion beforehand with all relevant parties. As personnel crew change, the procedures and plan must be explained to the oncoming staff by means of a recorded tool box talk so that they are fully familiar with their responsibilities and the required precautions (g) Daily tank atmospheric tests will be carried out by two designated responsible persons in order for the Entry Certificates and Hot Work Permits to be issued. They will wear 10/15 minute escape sets until the space is found to be gas free. (h) Prior to the commencement of work in the tanks, a Tool Box talk will take place at the tank entry, with a Tool Box talk checklist being completed. TANK PREPARATION FOR HOT WORK (a) For cargo tanks and ballast tanks contaminated with hydrocarbons, the tank atmosphere must in all cases be purged with inert gas until atmospheric testing indicates the hydrocarbon content is less than 1% by volume. The inert atmosphere will then be diluted with air until 21% by volume is obtained without toxic gases being present. (b) All adjacent cargo tanks (tanks with a common longitudinal/ transverse or "corner" bulkhead) should be (1) either clean, gas free and under air, or (2) ballasted to a minimum of 2 metres higher than the location of the welding, and also clean, gas free and under air. Note: A relaxation may be applied. This relaxation will clearly explain why section (b) above cannot be complied with. (c) When hot work is taking place on a common bulkhead, the reverse sides of the bulkhead will also be thoroughly cleaned or clean ballasted to above the hot work area. Other areas that may be affected by the hot work must be given particular attention, e.g. the area immediately below the place where the hot work is being undertaken, with consideration being given to the deck head immediately above the work area if this is relevant due to its proximity to the hot work. (d) Where © above cannot be complied with (with respect to thoroughly cleaning the reverse side of the bulkhead in conjunction with man entry) due to operational constraints, then the following can be implemented and incorporated within the HW procedure after discussions with the Production Operations Manager, HSE Manager, FPSO Engineer, Marine Supt, Unit Operations Manager, and OIM / Unit Superintendent: The adjacent tank will be crude oil washed, water washed, and inerted with clean IG. The IG in the adjacent tank will suppress the 02 content to a level as low as possible, the level must not rise above 5%. Constant monitoring of the 02 content must be in place. Purging the Cargo Tank by IG gas must reduce the hydrocarbon content to 1% or less by volume. - 10 - 21/03/05 PART 2 - HW IN CARGO AND BALLAST TANKS 2.7 CODES OF PRACTICE AND OPERATING PROCEDURES MANUAL PART 1 - GENERIC CODES OF PRACTICE OFFSHORE HOT WORK PROCEDURES 00 HW IN HAZARDOUS AREAS – APPROVAL AUTHORITY LEVELS HW IN CARGO & BALLAST TANKS GENERAL HW IN HAZARDOUS AREAS 07 90 029 ISSUE 01 REV. 01 (e) All pipe work serving, or passing through the tank, should be flushed with water and left filled with water where practicable. Heating coils must be flushed prior to blanking. (f) All valves in, or leading to the tank will be chain locked closed, or their operating handles removed, "Do Not Operate" Tags shall be attached. All valve motive driving mechanisms shall be isolated, and the permits annotated accordingly. (g) All pipe work, i.e. cargo, COW, heating coils, and IG/vents in the cargo tank will preferably be spaded off as close as possible to the termination. If this is not possible, then a two valve isolation must be in place. If a two valve isolation is not possible, then a R/A must be carried out and approved by the O.I.M./Unit Superintendent. (h) The tank will have been thoroughly crude washed and water washed and drained of all hydrocarbon deposits, sludge scale and sediment 5m around the hot work location, this 5m clean zone will extend 10m back from the HW site along the bottom plating, to the satisfaction of the O.I.M./Unit Superintendent, Area Authority, Safety Officer and the Safety Consultant. If solid deposits remain, they must be fully removed. (i) When considered feasible a water-bottom should be introduced, this being the case, then the O.I.M./Unit Superintendent will decide if floatation aids for personnel are necessary. (j) The tank will be ventilated with air until the space contains 21% oxygen by volume as measured by an in date calibrated oxygen meter. Ventilation must be continuous. Local ventilation may be required to combat welding fumes. (k) Initial entry atmospheric tests will be carried out by the Safety Officer and the Area Authority who will wear an approved emergency escape BA set, safety harness, radio, and in date calibrated portable gas meter whilst in the tank. These tests will have been preceded by remote sampling of the tank using a gas meter with an extension tube. (l) Pressurised and secured fire hoses to be run down in the tank to the hot work site area, and portable powder fire extinguishers to be located adjacent to the work area. 2.8 WELDING MACHINES / ELECTRICAL EQUIPMENT (a) Diesel welding sets, diesel air compressors etc. which are to be used in conjunction with the hot work will be inspected onshore by the Shore Base Unit Operations Manager. The completed inspection sheet being forwarded to the Marine Unit. (b) Daily checks on the equipment when it is on the Marine Unit will be carried out by the I/E Supervisor, and the Maintenance Superintendent, or their deputies. (c) All electrical equipment for use in the tanks and on the deck in the hot work area will be BASEEFA rated, or of an equivalent standard for use in hazardous areas. (d) All electrical and mechanical equipment will undergo a full and comprehensive inspection by the Maintenance Department prior to its use. (e) The diesel welding sets, and air compressors will be subject to a separate Hot Work Permit when on the Marine Unit, and may not be started without the express approval of the Safety Consultant after suitable atmosphere and area checks have been completed. - 11 - 21/03/05 PART 2 - HW IN CARGO AND BALLAST TANKS PART 1 PART 2 PART 3 CODES OF PRACTICE AND OPERATING PROCEDURES MANUAL PART 1 - GENERIC CODES OF PRACTICE OFFSHORE HOT WORK PROCEDURES PART 1 PART 2 PART 3 00 (f) 2.9 HW IN HAZARDOUS AREAS – APPROVAL AUTHORITY LEVELS HW IN CARGO & BALLAST TANKS GENERAL HW IN HAZARDOUS AREAS 07 90 029 ISSUE 01 REV. 01 Welding equipment should be provided with a "go and return" system utilising two cables from the welding set. LIVE BULKHEADS (HYDROCARBONS PRESENT IN THE ADJACENT TANK) (a) Hot work is not normally allowed within 500mm of a live bulkhead. Note: An exceptional relaxation may be applied which permits HW to within 250mm of a live bulkhead. This relaxation will clearly explain why section 2.9 (a) above cannot be complied with. This relaxation would only be considered when a full Risk Assessment has been carried out, and approved by the O.I.M./Unit Superintendent, the Shore Base Manager, the Production Operations Manager and the HSE Manager. When hot work comes within 1m of a live bulkhead, the 500mm or 250mm exclusion zone mentioned in 2.9 (a) above is to be clearly marked on adjacent plating to identify the prohibited hot work areas. TANK HOT WORK SAFETY PROCEDURES (a) The SBMPC Permit to Work System shall be complied with. (b) No diversion of production is permitted other than to approved tanks, and no tank cleaning, purging, gas freeing or bunkering will be permitted whilst hot work is in progress. (c) Hot work is not allowed during offloads to an export tanker. (d) The O.I.M./Unit Superintendent retains his normal overall responsibility for the safe execution of all work being carried out on the unit. (e) Calibrated portable gas meters will be located at the hot work sites and will be monitored by the fire watchers. The meters will be checked daily, at the end of the days work, and prior to use the following day. (f) At the hot work location, a minimum of two gas meters should be employed, one at the worksite with the Fire Watcher, the other with the Standby Man at the tank entry. (g) A Standby Man will be positioned at the tank entry, his main task is to maintain contact with the work party and to maintain the record of personnel in and out of the tank by recording their names on an entry check list, or by using a name tag system. He will also periodically sample the hot work tank from his location at the tank entry. The Safety Consultant will periodically sample the boundary tankage atmosphere. (h) Lifelines and safety harnesses must be available where there is a risk of falling from a height of more than 2 metres; any staging used must be substantial and fit for purpose. (i) Communication will be established, tested and maintained between: ∗ The hot work site, the tank internal Fire Watcher and the Standby Man at the tank entry. ∗ The Standby Man and the agreed communication centre. ∗ The hot work site and the Safety Consultant - 12 - 21/03/05 PART 2 - HW IN CARGO AND BALLAST TANKS 2.10 CODES OF PRACTICE AND OPERATING PROCEDURES MANUAL PART 1 - GENERIC CODES OF PRACTICE OFFSHORE HOT WORK PROCEDURES PART 1 PART 2 PART 3 HW IN HAZARDOUS AREAS – APPROVAL AUTHORITY LEVELS HW IN CARGO & BALLAST TANKS GENERAL HW IN HAZARDOUS AREAS 00 90 029 ISSUE 01 REV. 01 The welding machine Fire Watcher and the hot work site Fire Watcher. (k) Hot work may normally only be conducted in one cargo/ballast tank at any one time. If HW is required in more than one tank at the same time a Risk Assessment will be completed under the authority of the O.I.M./Unit Superintendent and approved by the Shore Base Unit Operations Manager, for final approval by the Production Operations Manager, and the HSE Manager. (l) HW is allowed in one tank with entry into another tank taking place for mechanical work under the control of a CW permit. However, a Risk Assessment will be completed for approval by the O.I.M./Unit Superintendent. (m) Notwithstanding the fact that welding, cutting and burning and other hot work may be being conducted in the tanks, smoking is prohibited in the tanks and on deck. (n) Personnel entering the tank will take a 10/15 minute escape set and a portable radio with them. Rescue BA sets being located at the tank entry for use by the Emergency Response Team. (o) The minimum number of personnel allowed in a tank is two. (p) The maximum number allowed in a tank will be decided by the O.I.M./Unit Superintendent, based on safe working practices and must not exceed the safety equipment available for each person involved in the tank work. (q) Each work party entering the tank will have one person nominated as the "Radio Man". Each person entering the tank will carry an approved ELSA escape set, (this set need not be worn continually, but shall be kept immediately available in the work area). In addition to the normal company required personal protective equipment (PPE), welding PPE will be required to be worn by the welders or those using burning gear. (r) No one may enter the tank in which the hot work is to take place before the Area Authority has issued an Entry Certificate (s) Following this, no person may enter the cargo/ballast tank without the permission of the Work Force Supervisor or Safety Officer, they will verify that the necessary tests have been completed and that the Entry Certificate and the Hot work permit have been raised. The Area Authority and Safety Officer will also visit the work site area in the tank prior to the commencement of the work, and at regular intervals during the work. These visits are in addition to the visits carried out by the Safety Consultant. (t) Subject to a satisfactory daily inspection in which the following conditions exist, the Entry Certificate can be raised for personnel entry, (no hot work must take place without a valid Hot Work Permit complementing the Entry Certificate). (u) ∗ Hydrocarbon gas Virtual Zero ∗ Toxic gases (H2S & CO) Zero The Hot Work Permit and the Entry Certificate will be valid for 12 hours with gas tests carried - 13 - 21/03/05 PART 2 - HW IN CARGO AND BALLAST TANKS ∗ 07 CODES OF PRACTICE AND OPERATING PROCEDURES MANUAL PART 1 - GENERIC CODES OF PRACTICE OFFSHORE HOT WORK PROCEDURES PART 1 PART 2 PART 3 HW IN HAZARDOUS AREAS – APPROVAL AUTHORITY LEVELS HW IN CARGO & BALLAST TANKS GENERAL HW IN HAZARDOUS AREAS 00 07 90 029 ISSUE 01 REV. 01 out before entry and after breaks. If the hot work is suspended for any reason for more than 60 minutes then the Entry Certificate will be re-validated. (v) The Entry Certificate immediately becomes invalid if any valve, pipe or joint is opened or broken, or if any other event occurs in the tank or adjacent tanks which in the opinion of the Safety Consultant would present a hazard to the on-site personnel. (w) In the event of hot work being stopped because of the above, the Safety Consultant will discuss the situation with the Area Authority in order for remedial steps to be put in place so that the work can safely recommence. (x) If, during the course of the hot work activity it is considered necessary to break into any lines that may contain hydrocarbons in the tank, then all hot work shall stop. Prior to hot work recommencing, a new Hot Work Permit, and Entry Certificate must be raised. FIRE WATCHERS (a) During open flame hot work operations, a minimum of two Fire Watchers (in radio contact with each other and the hot work party) are required. One to be stationed continuously in the tank, and one at the welding machine. They will be totally independent of the ongoing work, i.e. they are there to observe and monitor the area, should a fire, or other hazardous situation develop, they will notify the Work Force Supervisor and Area Authority immediately and if safe to do so, attempt to fight the fire. (b) The O.I.M./Unit Superintendent will however assess the Fire Watcher requirements over and above this minimum number. (c) When hot work is stopped for the day, breaks, or completion, the Fire Watcher (accompanied by one other person if the tank is empty of personnel) will observe the hot work location for a period of at least 30 minutes. The Standby Man at the tank entry will stay in position until all personnel have left the tank. (d) The Fire Watchers must not leave their station without the strict approval of the Area Authority. They will report directly to the Area Authority and must be fully conversant in the English language. (e) The Marine Unit Safety officer will brief the Fire Watchers on their duties, and a record will be kept in the Marine Unit Safety office listing those personnel trained in fire watching procedures. (f) The Fire Watchers at the hot work site should be provided with dark glasses to avoid "arc eye". 2.12 (a) EMERGENCY PLAN An emergency plan shall be produced by the O.I.M./Unit Superintendent, Area Authority and Safety Officer and reviewed by the Safety Consultant and tested prior to the start of any hot - 14 - 21/03/05 PART 2 - HW IN CARGO AND BALLAST TANKS 2.11 CODES OF PRACTICE AND OPERATING PROCEDURES MANUAL PART 1 - GENERIC CODES OF PRACTICE OFFSHORE HOT WORK PROCEDURES PART 1 PART 2 PART 3 HW IN HAZARDOUS AREAS – APPROVAL AUTHORITY LEVELS HW IN CARGO & BALLAST TANKS GENERAL HW IN HAZARDOUS AREAS 00 07 90 029 ISSUE 01 REV. 01 (b) The Emergency Plan will be tested prior to work commencing in the tanks with the Safety Consultant present. Emergency response capability is to be kept under review with refresher exercises taking place. (c) Sufficient rescue equipment must be provided at the tank entry in order to provide effective cover, this equipment will remain on location throughout the duration of the work. This equipment should be dedicated to this type of work and not normally drawn from the Marine Unit fixed inventory (see equipment list). (d) Additional rescue ELSA, O2 resuscitator, rescue line and stretcher will be available at the tank entrance together with sufficient manpower available to effect rescue. The Marine Unit Safety Officer will check the equipment on a daily basis. (e) A rescue tripod to be set up over a suitable tank opening and shall remain in place throughout the tank hot work. All involved personnel must be familiar with the rescue plan, they must also be familiar with all the routes to the escape ladders when in the tank (f) All personnel involved in the cargo/ballast tank hot work will be given an induction course on the Marine Unit emergency procedures prior to initial tank entry to ensure that they understand how to don, use and wear the escape sets. 2.13 COMMAND AND CONTROL OF EMERGENCY SITUATIONS (a) The O.I.M./Unit Superintendent will retain his overall responsibility for control of any emergency or developing emergency. (b) Contingency plans must be in place to cover the required procedures for the Fire Watchers should a Marine Unit emergency occur and personnel have to report to their Muster Stations. All Permits and Entry Certificates will be automatically withdrawn in the event of an alarm.

To be read in conjunction with the general guidelines contained within paragraph 9.3 HOT WORK, Section 9, Working Safely, Health, Safety and Environmental Manual (or Chapter 2 Section 4 – 1.5 of the HSEP Shipboard Manual) This type of Hot work is classed a Category 1. Category 1 Hot work APPROVAL LEVELS, i.e. which tasks have to be approved by the Production Management Office in Monaco, and those that can be approved by the Shore Base Unit Operations Manager, plus the O.I.M./Unit Superintendent are detailed in Part 1 of this Code Of Practice. The procedures described within Part 3 of the Code of Practice refer to those hot work activities that have to be approved in the Production Management Office in Monaco. However the safety principles as described in Part 3 have equal relevance in those hot work procedures approved locally in the Shore Base. 3.2 INTRODUCTION Work that has to take place in a hazardous area that may involve hot work must in the first instance be reviewed to determine if hot work is really necessary, i.e. could the task be effectively carried out using cold work? There may be locations onboard or conditions where live hot work is not a suitable option without recourse to specific additional safety precautions. In these circumstances pressurised habitats could be used in extreme circumstances with the use of a separate check sheet to cover the integrity of the habitat. If it is considered by any of the signatories to the Review and Approval Table that the appliance of all the mitigating precautions and procedures does not reduce the risk level to an acceptable level (as per the Risk Assessment) then the decision will be taken to isolate equipment as appropriate, and if necessary to shutdown the FPSO/FSO if it is essential that the hot work has to take place. If hot work is the only solution then a clear method of work must be developed, reviewed, and approved, in order that the work is carried out, monitored and completed in a safe manner. - 17 - 21/03/05 PART 3 – GENERAL HOT WORK IN HAZARDOUS AREAS PART 1 PART 2 PART 3 CODES OF PRACTICE AND OPERATING PROCEDURES MANUAL PART 1 - GENERIC CODES OF PRACTICE OFFSHORE HOT WORK PROCEDURES HW IN HAZARDOUS AREAS – APPROVAL AUTHORITY LEVELS HW IN CARGO & BALLAST TANKS GENERAL HW IN HAZARDOUS AREAS 00 07 3.3 RESPONSIBILITIES 3.3.1 O.I.M./Unit Superintendent 90 029 ISSUE 01 REV. 01 The O.I.M./Unit Superintendent will review the pending work that will entail hot work.
