Deepwater No 1, the world’s first 100,000-tonne deepwater semi-submersible production and storage platform, has been launched for operations offshore China
With the platform’s launch, Chinese national offshore oil and gas producer China National Offshore Oil Corporation (CNOOC) will now begin the process of installation and commissioning at the Lingshui 17-2 Gas Field Development Project. Water depths at the gas field average 1,450 m. A key component of the deepwater gas field development, the semi-submersible production and storage platform is being built to ABS class.
“We are delighted to support this important project. As the world’s leading offshore classification organisation, ABS’s extensive experience means we are uniquely placed to support delivery of a project of such scale, complexity and significance to the Chinese offshore industry,” said ABS senior vice president, global offshore Matt Tremblay.
Built by Yantai CIMC Raffle, the semi-submersible platform has a maximum oil storage capacity of nearly 20,000 m3 of condensate for ship-to-ship offloading. Located about 150 km southeast from Sanya city of Hainan province, Lingshui is the first deepwater gas project operated by CNOOC.
Annual production of Lingshui 17-2 is forecast to reach 3.2Bn cubic meters (bcm), with maximum production of 3.39 bcm.
The Linshui semi-submersible production and storage platform is a first for ABS in offshore classification, which has been at the forefront of offshore energy development for decades. Among its pioneering efforts are certifying the world’s first mobile offshore drilling unit in 1958 and classing the first jack-up, semi-submersible, drillship, FPSO, TLP and spar.
