China's CNOOC deploys first integrated large-scale fracturing vessel

China National Offshore Oil Corporation (CNOOC) launched the country's first integrated large-scale fracturing vessel, "Haiyang Shiyou 696," in Tianjin city, North China, which has entered the commissioning phase ahead of offshore operations, the Science and Technology Daily reported on Tuesday.

The report noted that the state-of-the-art vessel features advanced integration, intelligent systems, high displacement and power, substantial storage capacity, and strong operational capabilities needed for offshore fracturing.

Measuring 99.9 meters in length, a beam of 22 meters and a depth of 9.9 meters, the vessel is equipped with fracturing equipment, including fluid supply, mixing, and sand mixing systems and other material storage and supply equipment.

This marks a significant advancement in China's offshore oilfield fracturing technology that will bolster the exploration and development of China's offshore oil and gas resources, enhance China's competitiveness in the global oil and gas market, and infuse new vitality into the growth of marine economy, the company said.

CNOOC said the facility will meet the new demands for large-scale fracturing operations in the whole sea area of China, batch fracturing operations in multiple wells at sea, gas wells and ultra-deep fracturing operations. It also fills a key technological and engineering gap in China's offshore oilfield capabilities.

CNOOC said that mooring tests will be systematically conducted after the launch. The primary focus will be on the trouble-shooting system integration compatibility of various equipment operating in unison, simulating high-load conditions, assessing mooring forces under different dock water depths and tidal variations, and calibrating the synchronization of data collection. With few precedents to follow, the company is committed to advancing practical applications of new technologies.
