China's first domestically designed and built integrated large-scale fracturing vessel was delivered on Tuesday in Zhoushan City, east China's Zhejiang Province. The vessel, codenamed Haiyang Shiyou 696, will soon be deployed to offshore oilfields in remote waters, including in the Bohai Sea, to carry out hydraulic fracturing operations aimed at boosting productivity from low-permeability and low-mobility seabed oil and gas reservoirs.
