6 6 Opportunities Marine LNG Fuelled Power Systems Trigged by Fuel costs (HFO/MD versus LNG), emission legislation (IMO), availability of efficient and reliable engines and a growing gas infrastructure, the market for LNG fuelled systems is increasing. LNG fuelled solutions, mature technology. Rolls-Royce Marine is currently offering: Propulsion product supplies - that includes the Bergen C and B Gas engine and MTU engine versions Integrated, LNG fuelled ship power systems and Vessel building specifications/designs for a variety of Offshore, Merchant and Naval vessels

8 Gas Fuelled Engines 8 First lean-burn, spark plug ignited gas engine delivered in 1991 Gas engines for marine propulsion in service since 2006 More than 600 gas engines sold world wide. Power range 1400 kw to 8500 kw Machinery spaces are designed gas safe in all conditions, i.e.. inherently safer design Enclosure on all gas-carrying pipes In case of leakages in inner pipe gas is collected in outer enclosure and ventilated to mast Indication (Alarm) given to the operator or shutdown of the relevant engine depending on leakage size (% of LEL)

10 LNG Fuel Systems 10 A LNG Fuel System in our context comprise a storage tank (liquid gas) and a system for gas conditioning i.e. evaporation and temperature adjustment of the gas to the consumers (gas engines). Related to the above RRM also supply ACON GAS, for LNG Control and LNG Safety. Main design requirements as per the IGC code (IMO) and Regulations of Class.

12 12 Challenges System Design Realization Commissioning Operation

13 13 Challenges, System Design System Integration, A&C IMO and Regulations of Class set minimum standards for safety (and quality). Interpretation and following up varies. Verified system integration that includes all relevant system building blocks (internal and external) and interfaces safeguard in-service performance. Software development and validation control HIL testing is one option. Failure rate/life time expectancy for critical A&C components our approach through RRM Common Controls. Environmental factors (e.g. vibrations, temperature).

14 14 Challenges, System Design LNG Fuel Systems RRM is relying on thrusted suppliers but evident that marine experience is still lacking. Substantial efforts required: Technical Requirement Specification project based. Prequalifying process implemented for thrusted suppliers. Enhanced support and monitoring/logging. Low LNG temperatures and choppy sea - a challenge for gravity feed LNG systems. Mitigation strategies includes: Operational procedures. Cryogenic pump option on a when needed basis (patent pending). LNG storage tank designs (patent pending).

15 15 Challenges, Realization Power and control cabling quality, routing, shielding and termination by Yard can be a challenge. Min. requirements of Class and Owner not always aligned to specifications of OES. Completion of documentation and functional testing of the LNG fuel system processes as part of FAT enhance commissioning.

16 16 Challenges, System Commissioning RRM systems performance heavily impacted by Yard deliveries. Restricted time available for harbor and sea trials can be a challenge. Adaptions/Improvements of traditional commissioning planning and execution to reflect the complexity of the systems delivered are necessary. Experiences of gas installations by many Yards are restricted.

17 17 Challenges, Operation A highly efficient and flexible integrated propulsion systems impact the skills required for operating personnel. Dedicated training is necessary Simulator connected training in a true environment, now available. Restricted group size. Training for normal operation and fault troubleshooting in addition to gas basics. 24/7 In-Service support Parts Service and operational support through multi-disciplined teams of service engineers, that can be instantly mobilized for on-site troubleshooting and fault rectification. Energy Optimisation Services growing.
