Pontoon Barge Float–Over Installation of BZ28–2S Field
- Timeline: 2008
- Location: Bohai Bay, China
- Water Depth: 22,1m
- Operator: China National Offshore Oil Corporation(CNOOC)
- Client: China National Offshore Oil Corporation(CNOOC)
Project Description:
BZ 28 – 2S field located in the south of Bohai Bay, China with a water depth of 22.1 meters. ODL was contracted with CNOOC to perform the FEED to find an installation solution using float over method to replace the lift installation method.
ODL Scope of Work:
ODL performed the detailed pontoon barge float-over engineering analysis of two topsides of BZ28 – 2S field.
Key Details:
Determine Spacing Between Pontoon Barges; Design Sizes for Fender, Guide Rails and Gaps
Determine DSU Support Location at Decks; Determine Support Height at Pontoon Barges
Ballast Design at Transfer Operation; Ballast Design at Mating Operation
Ballast Design at Separation Operation; Check Clearances at All Operations
Develop pontoon barge installation procedures ( transferring; entry; mating; exit)
