Points of Consideration for LNG Fueled Ships

9. 3. POINTS OF CONSIDERATION LNG FUELED SHIPS
3.1 REGULATIONS
Standards and Guidelines assume a very important role in the development of LNG as a marine fuel.
ECAs are already in place in Northern Europe, by 2020 in Southern as well.
IGF is in place and greatly helps the design work, but:
There is still a lack of National Regulatory Framework.
Proposal for a Legislative and Regulatory Framework for the use of LNG as Marine Fuel – Vessels, Ports & Operations, within the framework of POSEIDON MED. This process is time consuming
Establishment of a task force between Ministry of Shipping and PMED II Partner Hellenic Lloyds to develop framework for adoption of LNG as fuel in Greece

3.2 TECHNICAL DESIGNS
Technical Design for an LNG fueled vessel applies both to existing ships (retrofit) and to new-builds.
In both cases, there is a number of technical considerations to be identified and analyzed before formulating the final technical solution.
Some of these considerations are:
- Input from the ship-owner regarding current operational profile of the vessel (in case of existing one) and operational profile under LNG.
- Interpretation and implementation of SOLAS and IGF Codes
- Class review and approval
Technical inputs from equipment suppliers
Risk and Safety issues (HAZID, HAZOP reports)
Analysis of Ports of call infrastructure characteristics
Complete Process Engineering to ensure LNG safe storage & usage on board.

11. 3. POINTS OF CONSIDERATION LNG FUELED SHIPS
3.3. OPERATIONS
Supply Chain:
Ship-owner to establish
a secured supply chain.
Bunkering Methods:
Ship-to-ship
Shore-to-ship
Truck-to-ship
Maintenance of LNG Equipment and Engines
Challenges to address:
Risk Analysis and Safety Management
High Bunkering Costs
Supply Chain
Ship-to-Ship bunkering

12. 3. POINTS OF CONSIDERATION LNG FUELED SHIPS
3.4 LNG TRAINING
LNG is very different to conventional fuels and therefore there is little experience outside ships carrying LNG as cargo with handling the product
Training of crew/personnel/operators :
To ensure safe and efficient LNG operations /handling on ships, at ports & at terminals
To understand challenges and risks
Training Regulations:
IMO MSC. 285(86): Interim Guidelines on Safety for natural gas fuelled engine installations in ships, adopted in 2009
STCW.7/Circ.23: Interim guidance on training for seafarers on ships using gases or other low-flashpoint fuels, approved in December 2014

13. 3. POINTS OF CONSIDERATION LNG FUELED SHIPS
3.4 LNG TRAINING
Training requirements are mandated by the EU and implemented by Flag Administrations alongside any national laws. Compliance with such requirements will be cross-checked by vetting inspectors and class societies.
Training will be type specific as decided by the company training manager.
Emergency procedures need to be developed specifically to deal with the additional hazards posed by LNG such as:
fire and leakage procedures
hazardous zoning and protection
safety exclusion zones
dropped objects
