FPSO Bohai Shi Ji Cold Work Repair


Project Type

Cold Work/Tank Top and Bulkhead Reinstatement


QHD32-6 Field, Bohai Bay, China




China Offshore Oil Engineering Corporation



SPS offshore Cold Work repair installation facilitated the 32m² bulkhead reinstatement to the inner bottom of the cargo oil tank No.1 Starboard onboard FPSO Bohai Shi Ji.

This innovative offshore repair method using SPS technology allowed for the following:

  • A safe and unhindered bulkhead reinstatement.
  • Adjacent tanks remained in service throughout this offshore repair.
  • The FPSO remained on-station, in full operation, whilst the work was carried out.
  • SPS offshore cold work repair method eliminated the risk of fire-related hazards in a restricted zone adjacent to live cargo tanks.

Adjacent tanks remained in service while the repair work was conducted, and the FPSO continued to operate without disruption. The cold work repairs eliminated the risk of fire-related hazards in a restricted zone, especially considering its proximity to live cargo tanks.

All SPS steel components were prefabricated onshore, including top plates and perimeter bars, reducing the need for extensive on-site work and minimising project duration and Personnel On Board (POB).

The composite panel created by bonding the solid elastomer core to the existing top and bottom plates effectively reinstated the structural integrity of the cargo tank. Not only did CNOOC save valuable time and resources, but the use of SPS offshore technology also improved the long-term performance of its oil cargo tank.
