McDermott has completed the transportation and installation subcontract of the Sao Vang and Dai Nguyet (SVDN) gas and condensate field developments in the Nam Con Son Basin, offshore Vietnam.
The EPCIC contractor was PetroVietnam Technical Services Corporation Mechanical & Construction (PTSC M&C). The subcontract was awarded to McDermott by PetroVietnam Technical Services Corporation (PTSC) Offshore Service Joint Stock Company for Idemitsu Gas Production Co., Ltd. (IGP). The scope of work included transportation and installation services for the central processing platform jacket, wellhead service deck, and topside floatover.
Completion of campaign one included a jacket launch using McDermott’s Derrick Barge 30 (DB30) in a water depth of approximately 372 feet (113.4 meters). At 12,600 metric tons, it is the heaviest and largest jacket launched in Vietnam at that water depth.
Campaign two included the largest floatover installation of a central processing platform topside in Vietnam, weighing 14,500 metric tons. The installation was achieved through a tight-slot floatover with less than four inches of clearance on either side.
