The flexible pipe approach can provide many technical advantages and cost savings over a rigid pipe approach when considered early for a project.

One such project is the Liuhua 11-1 Oil Field, located offshore China in 1000-foot water depth, which is being developed jointly by Amoco Orient Petroleum Company (AOPC), China National Offshore Oil Corporation (CNOOC), and Kerr McGee.

This paper presents a comparison of technical and cost issues examined by the project team during the bid stage of the project.

In addition, this paper details the technical challenges, and their solutions for the engineering, manufacturing and installation of Coflexip's flexible export pipe lines and flexible risers.
