For example, the semi-submersible "Tai 'an Kou Wheel" in China, the loading platform is like a football field. When loading and unloading large floating cargo, the loading platform can dive 19 meters, and the depth of the loading platform is 9 meters. Total length156m, profile width 32.2m, profile depth10m, and load capacity18000t. ?
Tai 'ankou is the first large-scale self-propelled semi-submersible ship built in Chinese mainland. The basic design was completed by Vuyk Engineering Center in the Netherlands, and the detailed design was entrusted to Shanghai Ship Research and Design Institute by GSI. 200 1 was launched at GSI on September 18, 2002, and delivered to customers for the first flight on February 18, 2002. The ship has a total length of 156 m, a profile width of 32.26 m, a profile depth of 10 m, a freeboard draft of 7.50 m, a speed of 14 knots, and an endurance of 13000 nautical miles, with a cost of 275 million yuan. It flies the flag of China and enters DNV. The loading deck is 32× 126 m, with a total area of 4065 square meters, total load 17550 tons and deck load 18t/m2. The whole ship has 43 ballast tanks and 2 floating tanks. With the help of four large-displacement low-pressure screw air compressors, it can quickly discharge 4500 cubic meters per hour, and the ballast discharge time is less than 4 hours, allowing the open cargo deck to dive vertically to a depth of 9 meters. It can carry goods weighing more than 10000 tons at sea. It is mainly used for shipping consignments of large steel structures, offshore oil exploitation platforms, submarines and warships. The design of the ship meets the requirements of infinite navigation area and can adapt to sea areas with various climates (such as the Arctic Ocean).
