Section 2 Submission requirements

2.1.1 In addition to the documentation required by the relevant Chapters of the Rules for Ships, the following shall be submitted:

1. Design statement that defines the service profile of the ship, together with a description of the arrangements, essential services as agreed by LR and the intended operating capability and functionality of the main propulsion and auxiliary systems that use methanol as fuel.

2. Risk-based studies undertaken to a recognised Standard and in accordance with LR’s ShipRight procedure Assessment of Risk Based Designs and associated annexes. The studies shall be documented so that the risks and how they are eliminated or mitigated are clearly identified, and an appropriate level of safety, dependability and hazardous areas classification is demonstrated, see Ch 1, 3 Risk-based studies.

3. Arrangement plans for methanol bunkering stations, fuel storage tanks, fuel supply equipment and consumers, and their location relative to high fire risk areas, accommodation, service and control spaces, water ballast, fuel oil, and other tanks containing flammable substances.

4. Process Flow Diagrams (PFDs) and Piping and Instrumentation Diagrams (P&IDs) for all fuel containing equipment. This shall include all pipework and equipment from the bunker connection through to the engine.

5. Hazardous area plans indicating the location of hazardous areas and their openings, access and ventilation arrangements. To supplement these plans, the documentation from the classification study described in Ch 1, 3.5 Hazardous areas classification study shall also be submitted.

6. Schedule of electrical and mechanical equipment located in hazardous areas.

7. Fuel supply system piping and equipment plans. Details shall include: system design and general arrangements; piping design including installation; ducting; valves and fittings; filters; pressure relief; purging arrangements; pumps and heat exchangers.

8. Plans and details of fuel storage tanks, holding tanks and pressure vessels, including filling, discharge, relief arrangements and tank penetrations.

9. Piping fatigue analysis, see Ch 1, 7.1 General 7.1.2.

10. Ventilation system plans for the machinery spaces, machinery enclosures or casings including air-locks, pipe ducting and any dampers in them, closing appliances and the position of the controls for stopping the system. Plans shall indicate hazardous areas where appropriate.

11. Enclosures or casing plans for consumers and any air locks where required.

12. Fixed methanol detection and alarm system plans.

13. Description of emergency shutdown arrangements, including a list of control, monitoring and alarm points, and the messages to be displayed for each alarm.

14. Operating manuals that describe the installation particulars, together with operating and maintenance instructions. Procedures for modifications to control systems to be included. Equipment manufacturers’ instructions shall include the drawings and diagrams necessary for putting into service, maintenance, inspection, checking of correct operation, repair of the machinery, the use of correct spares and tools, and useful instructions with regard to safety.

15. Description and plans of fuel control and monitoring systems and fuel changeover arrangements for dual-fuelled machinery, including line diagrams of control circuits and lists of monitoring, control and alarm points.

16. Quality plans for sourcing, design, installation and testing of all components and equipment used in the fuel system.

17. Evidence of type testing of the engine with electronic controls or a proposed test plan at the builders with the electronic controls operational, to verify suitability of the electronic control system and correct functioning during normal operation and identified failure modes.

18. Schedule of testing at engine builders and commissioning prior to sea trials, to demonstrate that the consumers are capable of operating as described in the design statement, including any testing required to verify the safeguards determined in the risk-based studies, see Ch 1, 3 Risk-based studies. The test schedules shall identify all modes of operation and the sea trials shall include typical port manoeuvres under all intended engine/turbine operating modes.

19. A cause and effect diagram to indicate the results of activation of each shutdown, shut-off and cut-out associated with the fuel system including engine operation and bunkering.

20. A suitable testing and inspection plan for fuel storage and supply system trials.

21. Methanol bunkering equipment arrangements and plans, operational procedures and maintenance instruction manuals.

22. Structural fire protection plan showing the main fire zones, the fire compartmentation bulkheads and decks within the main fire zones, including fire risk categorisation of spaces and class of all fire divisions. The plan should also allow identification of different types of space and their use.

23. Plans showing the details of fire-fighting and fire protection systems as required by Section 10 and the applicable statutory requirements.

24. A plan of the Alcohol Resistant Aqueous Film Forming Foam (ARAFFF) system. The plan shall show details of system arrangement, including calculations for the quantities of the media used and the proposed rates of application.

25. Fire Safety Operational Booklet including Methanol safety/emergency procedure. Refers SOLAS II/2 Reg. 16.2.

26. For existing vessels, details of any structural modifications are to be submitted.
