Rolls-Royce drives China’s move to gas with Asia’s first LNG-powered tug

China National Offshore Oil Corporation (CNOOC) has taken delivery of Asia’s first tugboat Hai Yang Shi You 525, designed to operate solely on liquefied natural gas as ship’s fuel, the company said in its press release.

Hai Yang Shi You 525, the first of two tugs built by the Zhenjiang shipyard for CNOOC, features a propulsion package based on twin Rolls-Royce Bergen C26:33L9PG engines and a pair of highly reliable Rolls-Royce US 205 CP azimuth thrusters to ensure the tugs have rapid manoeuvring and strong bollard pull capabilities.

A successful sea trial has proven an extra gain for both ship speed and bollard pull.

The decision to operate on LNG follows the Chinese government’s 2011 plan to strengthen its maritime base with the manufacture of high-end, ecologically-efficient ships and technology.

The Bergen C26:33 gas engines reduce CO2 emissions by 25 per cent and NOx emissions by up to 90 per cent. Oxides of sulphur and particulate are also removed, minimising emissions along coasts and inland waterways.
