Liuhua 11-1 development -- Phase 1 installation
The Liuhua 11-1 Field is situated in 1,020 ft of water in the South China Sea. The Liuhua 11-1 Development Project includes a floating production system and floating production, storage and offloading vessel with joining pipelines and risers. The installation occurred in two phases occurring over 12-months to take advantage of two favorable weather seasons. Phase 1, which forms the basis for this paper, was executed during May--July 1995 and includes laying of the moorings for both vessels and the hook-up of the FPS to its moorings. The scope of work and interface management required for installation of 21 mooring legs in this water depth is of particular importance. The vertical lay and tension system designed specifically for this project represented a large financial and engineering investment. The system was designed to lay the eleven mooring legs for the FPS and, ten mooring legs for the FPSO, and to tension the FPSO anchors to 1,323 kips (600 tonnes) at the anchor. The system had to handle three sizes of stud link anchor chain and two sizes of bare spiral strand wire rope. The Phase 2 installation of February--April 1996 includes connection of the FPSO to its moorings and installation of the three pipelines and their risers.
