Trip Overview 12-18 August 2012
Purpose: to provide a first-hand
assessment of maritime applications of LNG fuel on-going in Norway
• Principal contacts and facilitators (thanks!) – Odd Horgen, General Sales Manager Merchant/Naval Engines, Rolls-Royce Bergen – John Hatley, Americas Vice President, Ship Power, Wärtsilä North America
• Strategy – make contacts at CEO level if possible
• Result – all objectives were accomplished – reception far exceeded expectations

Initial Concern • Define the “Hazardous Zone”
– All ER/BR space? – Select spaces within?
Hazard Zone does not go away! • The “Space”, large or small, has,
– Redundant ventilation – Gas detection – Double wall boundaries Air locks / double wall pipe

“Protecting the path of Liquid/Gas”
From: • Bunker station, to: • LNG storage tank, to: • Cold box, to: • Gas valve unit, GVU, to: • Propulsion / Generator engine,
to: • Exit of exhaust stack

“Goals for Great Lakes Steamships”
• Minimize distance between units, and,
• Minimize volume of spaces protected
Inherently Safe Engine Room – Use double wall piping – Use containment structures – Separate ventilation systems – Appropriate gas detection
points
The Shipyards Perspective of “LNG Fuel and Great Lakes Steamships”
Presented by: Great Lakes Maritime Consulting LLC
“Challenges” • Delivery, handling and lifting of 90 ton plus tanks • Double wall piping (including everything within path)
• Additional and separate ventilation systems • Addition of nitrogen generator for purging • Addition of water spray at bunker station • Additional gas detection systems (in pipe / spaces)
• Mid season layup – winter layup – remaining bunker levels • Being the “Pioneer”
– Engineering / regulatory / production • Cost justification?

“Advantages” • Elimination of ALL HFO related equipment • CLEAN engine room • Less engine maintenance requirements • Less dynamic machinery – fewer moving parts • CLEAN EMISSIONS

Some General Observations
• Young and talented officers • Crews preferred being on LNG ferries • Viking Princess had LNG onboard and was using one of its
smaller dual fuel generators for ship’s power dockside 4 weeks before delivery
• Norwegian LNG vessels are dry docked with LNG onboard • The nation appears proud of environmental implications
of LNG use – a marketable item • All vessels had modules built in a partner shipyard
Overall Conclusion
While the use of LNG fuel involves new, higher technology and additional safety considerations, the use of LNG as a marine fuel for non-LNG cargo vessels is now routine practice in Norway after the introduction of the ferry MV Glutra 12 years ago.
