Case Studies


A massive project, with huge challenges

The CNOOC Deep Sea No 1 prides itself as the world’s first 10,000 ton semi-submersible oil storage platform. This massive energy station will be used to develop the gas field that was newly discovered in August 2014 in the Lingshui area just southeast of South China’s Hainan Island, with a maximum depth up to 1500 meters. This is a significant find, with it being the first major oil and gas discovery made from China’s self-operated deep-water exploration. The gas field that Deep Sea No 1 services is so large that it can provide 3 billion cubic meters of gas, which meets ¼ of gas demand in the Guangdong-Hong Kong-Macao Greater Bay Area, by delivering clean energy from the deep sea through the underwater pipeline around Hainan Island.

PTSC Vietnam

A range of unique designs

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.

Petrochemical Corporation of Singapore

Conducting intricate site measurement at PCS

As the centre company of the Singapore Petrochemical Complex, PCS’s main role is to supply high quality ethylene, propylene, acetylene, butadiene, 1-butene, MTBE and benzene. It also supplies utilities such as water, steam, and compressed air to pipeline customers, that in turn produce high quality petrochemical products for their customers. In addition, PCS produces toluene and xylene, which are exported to the Southeast Asia region and beyond for further processing.

For this project, we encountered a unique circumstance where the clients were unable to provide the necessary drawings that would accelerate the design process. Furthermore, there were many obstructions around the areas of intended application.
