DeepOcean UK completes Chinese subsea piping project

Offshore staff

DARLINGTON, UKDeepOcean UK has completed work on a Chinese oil and gas project. The work was DeepOcean’s longest pipeline trenching order to date – at 174 km (108 mi) – when it was secured on behalf of China Offshore Oil Engineering Corp. (COOEC) in early 2012.

The work for COOEC saw DeepOcean carry out work on Liwan 3-1, which is part of the Liwan gas project, 300 km (186 mi) southeast of the Hong Kong Special Administrative Region.

DeepOcean used multi-purpose offshore vessel Volantis and UT-1, a free-flying jet trencher, to conduct trenching and survey operations on the Liwan Pipeline. A key component of the project, the pipeline connects the gas field’s central platform to the shore at China National Offshore Oil Corp.’s (CNOOC’s) Gaolan gas plant.
