Enping FPSO Mooring Pile

LM Handling has provided handling expertise and equipment to support Acteon sister company, InterMoor, in the successful mooring installation of a floating production, storage and offloading (FPSO) unit for the China National Offshore Oil Corporation (CNOOC) operated Enping 24-2 oilfield in the South China Sea.

With LM Handling’s lifting and handling expertise and equipment, a 12-pile anchor mooring system, consisting of three clusters of four mooring lines, was installed.

LM Handling provided its StabFrame-S in its extended configuration, pre-loaded with additional ballast to achieve a stable and safe install for the long mooring piles. 84" and 60" Internal Lift Tools (ILT) were also supplied to the project by LM Handling. With a customised set of handling equipment, which enabled pile upending on the seabed, InterMoor was able to use a relatively lightweight construction vessel to install the piles quickly, efficiently and safely.

This mooring project represents LM Handling’s first venture in Chinese waters and a second project for the StabFrame-S, which was specifically designed for lightweight South East Asia vessels. Globally, it is the fourth successful FPSO mooring project for LM Handling.

Robin van der Bij, managing director at LM Handling, said, “The Enping project has been a positive demonstration of how company collaboration can overcome difficult challenges and secure the smooth delivery of a project. It also means a fourth successful FPSO mooring installation for the StabFrame, which guides the piles into the location and stabilises them to assist with penetration.”

InterMoor led the project, bringing together specialist services from Acteon group companies, including MENCK for the piling spread, and newly acquired UTEC Survey for the data requirements.

Enping 24-2 oilfield is in the Pearl River Mouth basin of the South China Sea, which has water depths between 86 and 96 m. The main production facilities include a drilling and production platform, an FPSO, and 17 producing wells. CNOOC has announced that two wells are producing approximately 8,000 bbls/d of crude oil. The project is expected to reach peak production of 40,000 bbls/d in 2017.
