Global power systems company Rolls-Royce, has signed a contract to deliver engines and propulsion systems for what is claimed to be the world’s first Liquid Natural Gas (LNG) powered tugs. The two vessels have been ordered by Norwegian company Buksér og Berging AS and will enter service in late 2013 for Statoil, the international energy company, and Gassco, the operator of the gas transportation network off the Norwegian coast.
Robert Løseth, Rolls-Royce, Senior VP – Merchant, Propulsion Systems and Engines said: “This is a breakthrough for our Bergen gas engines and cutting edge propulsion technology. The choice our customer has made highlights the industry leading engine performance, fuel consumption and low methane emissions that Rolls-Royce can offer, which is now being applied to tugs.”
In addition to two gas engines and an LNG tank system, Rolls-Royce will deliver an azimuth propulsion system for each tug, which will provide the quick and responsive manoeuvring that is critically important for tug operators.
The combined power and propulsion system is estimated to give a reduction in CO2 emissions of 30% compared to similar conventional vessels, and will comply with all known future emission regulations.
