AsianOil: McDermott installs platform offshore Vietnam

International service provider McDermott has successfully installed a production platform over the Sao Vang and Dai Nguyet (SVDN) gas and condensate field in Vietnam’s offshore Nam Con Son Basin.
McDermott said on September 2 that as the project’s subcontractor it had transported and installed the central processing platform jacket, wellhead service deck and topside floatover. PetroVietnam Technical Services Corporation Mechanical & Construction (PTSC M&C) was appointed the engineering, procurement, construction, installation and commissioning (EPCIC) contractor by Japanese developer Idemitsu Gas.
Idemitsu operates the field with a 43.08% stake, while Japan’s Teikoku Oil owns 36.92% stake and state-owned PetroVietnam has 20%.
McDermott said it had used one of its derrick barges to launch the 12,600-tonne jacket launch in around 113 metres of water, noting that it was the largest and heaviest jacket to be launched at such water depths in Vietnam. This was then followed by the largest floatover installation of a central processing platform topside in Vietnam, weighing in at 14,500 tonnes.
McDermott noted that the work had been delivered within budget and without any delays, despite the challenges presented by the coronavirus (COVID-19) pandemic.
The SVDN field lies within Blocks 05-1b and 05-1c, which cover around 1,570 square km. The field development plan, which received government approval in 2017, has set a target production of 1.5bn cubic metres per year of gas and 2.8mn barrels per year of condensate.
First gas was delivered from SVDN in November 2020, with PetroVietnam saying at the time that the field’s successful development underpinned its Nam Con Son 2 gas pipeline. The Golden Star floating storage and offloading (FSO) unit also received the field’s first condensate production in November 2020.
Elsewhere in the Vietnamese upstream, Batavia Oil announced last month that it had successfully concluded its acquisition of a non-operated stake in the offshore Rang Dong field, which is located in Block 15-2. The company said on August 20 that it now owned 100% of Perenco Rang Dong, which holds a 30.5% stake in the field.
