Mooring Design for Octagonal FPSO

• Timeline: 2009
• Location: Weizhou Bay
• Water Depth: 40m
• Operator: CNOOC
• Client: CNOOC RC (Research Center)

Project Description:
ODL was contracted by the CNOOC Research Center to design and develop an economical mooring solution for an octagonal-shaped FPSO and shuttle tanker to be deployed in Weizhou 11-7 field development in Weizhou Bay.

ODL Scope of Work:
ODL was to design and analyze multiple mooring systems and configurations and provide CNOOC with a recommendation for the best system.

Key Details:
Performed Frequency Domain Analysis, Time Domain Quasi-Static Analysis, and Time Domain Fully Dynamic Analysis on the FPSO and Shuttle Tanker in both fully loaded and ballasted conditions.
Designed a polyester mooring system and saved CNOOC $10.7M compared to utilizing a more conventional Chain mooring system.
ODL provided the CNOOC Research Center with detailed equipment lists, configuration drawings, and mooring installation procedures for both the polyester and chain mooring options.
