Sofec said on Wednesday that the construction was completed at the Penglai Jutal Offshore Engineering Heavy Industries in December.

Integration into the FSO will take place in Shenzhen beginning in January 2020 and is expected to be completed by March 31, 2020.

The system is a disconnectable internal turret system that will be integrated into a replacement FSO and connected to the existing Lufeng 13-2 field mooring legs and submerged buoy, which were replaced in 2012 for a field life extension.

The initial system for this field was originally designed and installed in 1993 and was chosen to allow the FSO to disconnect and sail to safe harbor as typhoons approach. The FSO can then return to the field and reconnect after the typhoon has passed.

Under normal operating conditions, the turret allows the FSO facility to continually rotate into prevailing weather without production interruptions.

The company added that it was responsible for all EPC activities related to the turret mooring system and its ancillary components. Sofec will assist in turret integration and offshore hook-up and commissioning activities in China planned during the first and second quarter of 2020.

Rick Hall, Sofec’s CEO, stated: “We are very proud to be awarded this reinstatement contract and to successfully deliver the completed turret system. The original installation in 1993 was Sofec’s first project with CNOOC and has been followed by several others.”

It is worth reminding that Sofec won the Lufeng permanent reinstatement project provision of the turret system from CNOOC back in August 2018.

As for the FSO, it is being converted from a 110,000 DWT crude oil tanker with an overall length of 245 meters. The original system from 1993 moored a Modec-converted 121,361 dwt FSO in the typhoon alley area offshore China.
