Taisun - Wikipedia
Taisun (Chinese: 泰山 ; pinyin: tàishān ; Taishan) is a gantry crane with a safe working load of 20,000 metric tons (22,046 short tons).[ 1] Taisun was designed by DHHI (Dalian Huarui Heavy Industry)[ 2] and built for the installation of very large modules in semi submersibles and FPSO projects. It is located at Yantai Raffles Shipyard in Yantai, Shandong Province, China. The gantry crane holds the record for the heaviest weight lifted by a crane.[ 3]
The amount of wire required to operate Taisun is nearly 50,000 meters or just over 31 miles, allowing it to lift a maximum of 80 meters.
Taisun was built to install very large (up to 20,000 tons) integrated modules on top of a vessel's hull. Traditionally, offshore vessels such as drilling semi submersibles or FPSOs were built from the ground up in modules of 1000 to 2000 tons, which meant that much installation, hook up and commissioning work was left to be done on board where access is limited and efficiency is decreased.
