Project: Bozhong 19-6 Condensate Gas Field Pilot Area Development Project

Time of completion: June 2020

Project introduction: The scope of work for this project includes the construction of a four-leg jacket-type wellhead platform, the laying of a 13.9km submarine gas transmission pipeline, a submarine double-layer insulated pipelines for mixed transmission and a composite submarine cable, and the checking of the old platform and old submarine pipelines.

Project highlights: Bozhong 19-6 condensate gas fields are located in the central Bohai Sea. The production platform of this project represents the first high-pressure gas production platform in the Bohai Sea with a maximum wellhead pressure of 25.9 MPa. The project was put into operations only 14 months from the completion of feasibility study, indicating a significantly shorter construction time compared with conventional projects of the same scale. Detailed design was commenced one month after the initiation of basic design, and construction was commenced two months after the initiation of detailed design.
