On April 3, China’s first large integrated fracturing vessel “HYSY 696” slowly slid from the shipyard slipway into the Yangtze River, entering a new stage of launching and commissioning.
To meet the demands of large-scale development in offshore low-permeability reservoirs, in 2022, CNOOC took the lead in constructing the HYSY 696, a large integrated fracturing vessel. The “HYSY 696” is 99.8 meters long, 22 meters wide and 9.9 meters deep. It is equipped with a series of fracturing equipment and has highly integrated, intelligent, high-displacement, high-power, large reserves and high-safety operating capabilities. It can realize efficient and large-scale fracturing operations at sea and is the first domestically built integrated large-scale fracturing vessel.
This vessel is equipped with five 5000 HHP electric-driven fracturing pumps, achieving a maximum pumping power of 18.63 MW, ranking first globally. It has a maximum pumping capacity of 12.7 m³/min, ranking second in the world. Additionally, it features a storage capacity for fracturing materials of 1,260 tons, also ranking second globally. This vessel enables comprehensive large-scale volumetric fracturing of offshore low-permeability oil and gas fields.
China Oilfield Services Limited (COSL) participated comprehensively and throughout the entire process of the design and construction, conducting systematic research on the key technologies for large fracturing vessels and their safe operation. This provides solid technical support for the orderly advancement and safe operation of the construction project. The vessel is expected to be delivered to COSL for operation in 2025.
