Rolls-Royce Sizes Up Seismic Order

Posted on February 17, 2011

Rolls-Royce has received a US$27.2 million (£20 million) order from Chinese conglomerate Sinopec to design and equip a specialist seismic research vessel.

When operational, the vessel, a UT 830 CD, will carry out detailed surveys of the seabed to identify oil and gas reserves. The contract includes power and propulsion systems and a range of advanced automated handling systems for seismic equipment.

During research missions, the vessel will tow up to 14 cables, or “streamers,” each 10 km long. Seismic waves are sent deep into the seabed and the reflected waves are detected by hydrophones spread along the network of streamers. This data is then used to give a detailed 3-D profile of the geological features, including the location of oil and gas, often thousands of meters below sea level.

The vessel, which is 100 m long with a 24 m beam hull, will have a bollard pull of 130 tonnes. Shanghai Shipyard Co. will build the vessel for Shanghai Offshore Petroleum Geophysical Corp., which is part of the Sinopec organization. Delivery is set for 2013.
