PLATFORM CONSTRUCTION FROM AN ADJACENT SEMISUBMERSIBLE VESSEL

The concept of using column-stabilized semisubmersible support barges (SSSB) positioned alongside offshore platforms to provide gangway access for new platform construction is described briefly. Some historical information is related concerning development and use of this concept during construction of the Occidental consortium's Piper and Claymore platforms. Experience during more than 1,800 barge-days has proven the reliability of the SSSB concept for expanding access, efficiency, and productivity of platform construction over that previously achieved with conventional hulls in rough North Sea weather. The advantages and disadvantages of both conventional and SSSB hull configurations for different aspects of platform construction support are discussed.
