Vallourec announce that on February 28th 2021, the 6 inch line that Serimax welded has been recovered from seabed and link to semi-submersible without any issue, giving an end to this wonderful success in China. Serimax Welding Services, the international welding subcontractor, was awarded for the welding of these 2.93 kilometres 6 inch SCR. The field depth of 1,450 meter triggered significant technical challenge due to the fatigue sensitiveness of the SCR. In order to meet the ambitious challenge of China's first deep water project, it was necessary to start preparing for it in the last quarter of 2019 to address several actions and handle all aspects. Last campaign of SCR installation of 10, 12 & 18 inches will be launched in the coming weeks in a still uncertain environment due to the pandemic.
China’s Offshore Oil Engineering Company, established in Bohay Bay, is one of the largest contractors for offshore oil and gas industry in the Asia Pacific region. Approximately 57% of it is owned by China National Offshore Oil Corporation, the largest producer of offshore crude oil and natural gas in China. Lingshui 17-2, the first deep water project ever developed in China, started its journey in 2019, with COOEC overseeing deep-water development. Its deep water pipeline installation campaign was started last year with the first 6’’ Steel Catenary Risers installation on Deep Water in China; the last weld of this first SCR being performed last August 2020.
