INSTALLATION, TESTING, AND COMMISSIONING OF A DISCONNECTABLE TURRET MOORING FOR FSOU VESSEL IN A TYPHOON-PRONE AREA

A disconnectable turret mooring system and FSOU vessel have been installed for the Lufeng 13-1 Oil Field Development in 142 meter water depth in the South China Sea. This facility is unique by virtue of the tolerances maintained throughout the installation process, including high holding power anchor placement to final vertical and horizontal location of the combination steel and syntactic foam Spider Buoy. Adjustment of the anchor legs (combination chain-wire-excursion limiter-wire-chain) to compensate for variances in the individual anchor drag distances is discussed with recommendations given for consideration in preparing geotechnical survey specifications for areas where the soils characteristics are lesser known. Adaptation of equipment to the methods needed to perform the weather sensitive installation are discussed.
