Conceptual design of CNG RO RO Vessel
1 Introduction
1.1.
Introduction
Bhavnagar port infrastructure private limited (BPIPL) is planning to convert existing vessel to transport
Compressed Natural Gas (CNG) trailers via sea route.
To ensure that identification of the hazards associated with the operation of vessel is adequately
performed, a Hazard Identification (HAZID) workshop is planned for April 19th to 20th, 2022. This
document provides the details of the objective, scope, methodology and agenda for the study.
1.2.
Objectives
The objective of the assessment is to:
•
Identify hazards associated with the design and operations of the CNG RO RO vessel.
•
Develop hazard scenarios and identify potential causes, assess the related consequences, and
identify the existing protection, detection, and indicating mechanisms.
•
Suggesting opportunities of alternative options towards an inherently safer design or identify risk
mitigation measures to reduce the estimated risk.
1.3.
Project summary
The subject vessel will be RORO type and will transport CNG trailers between RAS-AL-KHAIMA (RAK) in
United Arab Emirates (UAE) and Bhavnagar in Gujarat, India for a period of minimum 20 years,
extendable by another 10 years. The RORO vessel shall be conceptually designed for the transfer
capacity of 20 MMSCFD to 30 MMSCFD. Currently 40’ Type I and Type IV CNG Trailers are considered
for the design.
The Vessel will i) load CNG Containers from shore, ii) transit to the destination port, and iii) unload of
trailers at desination port. A single voyage is estimated to take around 5 days.
Refer to Conceptual Design of CNG RORO Vessel (Doc# 422021-ADV-NAV-REP-1005) for detailed
information as provided in Appendix A.
The RO RO vessel will be designed and built in accordance with requirement listed in:
•
IGF International Code of Safety for Ships Using Gases or Other Low Flashpoint Fuels (Ratified IGF
code version adopted on 11 June 2015, ANNEX 1, RESOLUTION MSC.391 (95)
•
International Convention for the Safety of Life at Sea (SOLAS) Chapter II-1 Regulation 55 and
guidelines referenced by footnote MSC.1/ Circ.1212 or associated guidelines MSC.1/Circ.1455
•

2 Methodology
The Hazard Identification (HAZID) study is a systematic review of the possible causes and consequences
of hazardous events. It can be applied to all or part of the vessel or it can be applied to analyze the
operational procedures. It can be used for identification and assessment of potential hazards and their
causes and consequences
The basic HAZID study involves following tasks:
•
•
•
•
Development of Terms of Reference, which will include information on HAZID objectives, scope,
hazards to be considered, methodology, required personnel, & reference documents
The assembly of an appropriate team of experienced personnel, including representatives of all
disciplines involved in the area being reviewed and (as needed) interfaces with adjacent systems.
Short presentations detailing the scope of the study.
Completion of the HAZID workshop, the methodology of which is detailed in Figure 2-1
During the HAZID workshop, the following activities will be performed:
•
•
•
•
•
Application of the relevant guidewords to identify hazards and other HSE concerns.
Identification of causes and consequence associated with identified hazards and associated
safeguards and mitigation measures.
Recordings of the discussions will be entered onto worksheets summarizing the nature of the
hazard, associated consequences, threats, safeguards, risk ranking, and recommendations if the
existing safeguards are not deemed adequate.
HAZID workshop will be recorded in the worksheet template as provided in Table 2-1 below
As this is a novel concept no risk ranking will be performed for this study

3 Scope
The scope of the HAZID includes the design and operations of the vessel, and loading/unloading
operations. To perform the thorough review of the conversion and its associated effect on the vessel
operation, the HAZID study will be divided in to nodes as follows:
•
•
•
•
Trailer loading into RO RO vessel
RO -RO Vessel Transit
Trailer unloading at desination port
Dual fuel concept and arrangement
Guide words will be selected to stimulate discussion within a node and identify hazard scenarios that
articulate how the hazard is realized and the potential consequence that might arise. Following list
provides the example of general hazards, but not limited to.
