InterMoor is currently working for COOEC on two major permanent mooring systems for two floating production units.
The Liuhua 16-2 project is a turret-moored floating production and storage and offloading (FPSO) in 390 – 420m water depth. The mooring system comprises nine suction pile anchors with chain-wire-chain legs.
The Lingshui 17-2 project is a taut-leg semisubmersible floating production unit (FPU) located in Qiongdongnan Basin in the northern South China Sea at water depth ranging from 1220m – 1560m. The mooring system consists of 16 legs (4×4) built with driven piles, chain and polyester rope.
InterMoor’s scope in both mooring systems includes project management, review and verification of detailed design, detailed installation methodology and procedures, installation engineering, offshore preparation and execution.
InterMoor completed the Liuhua installation of the suction pile anchors in a shorter timeframe than expected. The mooring lines have also been pre-laid, with the hook-up of the FPSO expected in 2020.
The engineering scope of the Lingshui project is still ongoing. The project requires complex engineering as the water depth is over 1,500m and driven piles will be used. The offshore execution of the Lingshui project is expected to be next year.
These two projects are the 4th and 5th consecutive project awards from COOEC to InterMoor in the last seven years. Pivotal in the award were InterMoor’s prompt support and personnel availability in the country within as well as InterMoor’s solid global experience in permanent moorings, and trusted regional track record with COOEC. InterMoor integrated their team with COOEC’s office in Shenzhen, China, to ensure seamless interfaces with the client (COOEC), the operator (CNOOC) and the subcontractors.
