A range of unique designs
The PTSC Sao Vang CPP that serviced the offshore field was an interesting challenge due to the various unique designs of the fire protection jackets that were needed by the client.
The Sao Vang and Dai Nguyet offshore field is located in Blocks 05-1b and 05-1c in Nam Con Son Basin, in southern Vietnam. The field lies approximately 350km southeast of Ho Chi Minh City and the water depth in the project area is approximately 120m. The annual production from the Sao Vang-Dai Nguyet field is expected to be approximately 1.5 billion cubic metres (bcm) of gas and 2.8 million barrels (Mbl) of crude oil and condensate.
The condensate produced in the field is pumped to a floating storage and offloading (FSO) facility named Golden Star. A gas pipeline was laid to export up to 3bcm of gas from the Sao Vang and Dai Nguyet, as well as the Thein Ung and Dai Hung fields to the Nam Con Son 2 pipeline at the BK Thien Ung area.
The Sao Vang CPP is a massive structure with the topside weighing approximately 15,500 tonnes (t), while the jacket and piles weigh approximately 16,500t. The topside of the Dai Nguyet wellhead platform weighs approximately 1,500Tt with the jacket and piles weighing approximately 8,700t.
