Rolls-Royce LNG Engines to Propel Fish Food Carrier

| United Kingdom, London

NSK Shpiping cargo carrier LNG propulsionRolls-Royce liquefied natural gas (LNG) engines will propel a new cargo carrier designed by NSK Ship Design for Norwegian shipowner NSK Shipping, a coastal vessel operator based in northern Norway. The vessel will deliver fish food on behalf of BioMar Group and will be built by Tersan Shipyard in Turkey. The engine contract is valued at USD 6.5 million.

The new cargo carrier will be a slightly larger sister ship to NSK Shipping’s MS Høydal which was the world’s first LNG powered cargo vessel and which was ordered by NSK in 2010 and delivered from Tersan Shipyard in 2012. Both ships are designed by NSK Ship Design.

The 81.5m long vessel will be able to carry 2.700 tonnes of fish food to fish farms along the Norwegian coast.

Kristian Høydal, NSK Shipping, Managing Director said: “We are proud to be trusted once again by BioMar to deliver their finished product to the fish farming industry and to be able to work with Rolls-Royce on the delivery of a more environmentally friendly and effective LNG powered vessel.”

Helge Gjerde, Rolls-Royce, President Offshore and Merchant Solutions, said: “BioMar and NSK Shipping invest in modern technology that helps reduce fuel costs and environmental footprint. They are among the absolute frontrunners in the area of short sea shipping.”

The LNG Propulsion system comprises one eight cylinder Bergen C26:33 natural gas engine rated at 2160kW, Promas combined rudder and propeller system, one tunnel thruster in the bow and one in the aft, and a Rolls-Royce automation and DP system.

The vessel is also equipped with the Rolls-Royce hybrid shaft generator (HSG) propulsion system. This means the main engine also generates electricity for the ship. The Hybrid Shaft Generator will generate electrical power for the ship even if the engine power output varies, saving fuel. The HSG can also act as a propulsion motor (PTI) providing an alternative power source should LNG becomes unavailable – a prerequisite for class approval.

Bergen Gas Engines from Rolls-Royce are the only pure marine gas engines on the market using a spark plug ignition. Alternative dual-fuel engines use a small amount of diesel for ignition. The B and C Series engines emit around 22% (including methane slip) less CO2 per unit of power than a diesel engine and Nitrogen Oxide (NOx) emissions are reduced by 90%. Sulphur Oxide (SOx) emissions are negligible. Bergen gas engines deliver a significant reduction in fuel and lubrication oil consumption. In addition, the clean, safe engine rooms and advanced technology can reduce maintenance costs as well as providing a more pleasant working environment for the crew.

BioMar has 11 factories producing fish food, in Norway, Chile, Denmark, Scotland, Spain, France, Greece, Turkey and Costa Rica.

The new cargo carrier is expected to be delivered from the yard in 2017.
