On January 30, CNOOC announced that the jacket of the second phase of the "Shenhai No. 1" project was slid and launched in the northern waters of the South China Sea and was accurately in place, marking a new breakthrough in the offshore construction capacity of large-scale jackets in China's deepwater high-pressure gas fields.
It is reported that the offshore installation of the jacket of the second phase of the "Shenhai No. 1" project is carried out by sliding and launching. In this way, the jacket itself is used to use its own gravity and cooperate with the hydraulic jack to boost, so that the jacket slides smoothly from the barge into the sea, and then the jacket is hoisted and righted through the crane ship, so as to realize the installation in place.
