Darlington-based subsea specialist completes work on large Chinese oil and gas project

Darlington-based subsea specialist, DeepOceans has recently completed work on a large Chinese oil and gas project. The contract saw the construction of the longest pipeline trenching order in the company’s history at a whopping 174km, secured on behalf of China Offshore Oil Engineering Corporation (COOEC).

 

The Liwan 3-1 project is part of the Liwan gas project which includes the Liuhua 34-2 and Liuhua 29-1 fields. All three fields share a subsea production system, subsea pipeline transportation, and onshore processing infrastructure.

 

The project is part of the Liwan gas project - the first deepwater gas project in offshore China – and took place 300km south-east of the Hong Kong Special Administrative Region. Work on the project commenced in 2012 with surveying, trenching, construction works including the deployment of 100 “mattresses” along the pipeline in preparation for the lay.

 

The new pipeline connects the Liwan central platform - which lies at a 200m depth – to the shore of China National Offshore Oil Corporation’s Gaolan gas plant.

 

Tony Stokes, Director of Asia Pacific for DeepOcean, said: “It was a privilege to be part of such a momentus project in China. Working on both segments of China’s first deep water field development displats the confidence our clients have in DeepOcean’s ability to deliver trenching solutions, along with diver-less construction work scopes in the dynamic Asia Pacific region.”
