Rolls-Royce Marine LNG Fuel Systems
� 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

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).
Rolls-Royce Marine
Challenges, System Design
LNG Fuel Systems
• RRM is relying on ”thrusted suppliers” – but evident that marine experienceis still lacking.
Substantial efforts required:
Technical Requirement Specification – project based.
14
Insert filename
� 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).
Rolls-Royce Marine
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.

processes as part of FAT enhance commissioning.
Rolls-Royce Marine
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.

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.

• 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.
