Taisun


Taisun is a gantry crane with a safe working load of 20,000 metric tons. Taisun was designed by DHHI 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.
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.

Concept

Taisun was built to install very large 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.
Taisun facilitates simultaneous construction of the lower and upper parts of the vessel which allows for a shorter overall project schedule, manpower improvements of up to two million man-hours while safety and quality levels are improved.

Lift Record

The Guinness World Records state that Taisun holds the world record for "heaviest weight lifted by crane", set on April 18, 2008 at 20,133 metric tonnes by lifting a barge, ballasted with water. However, it was surpassed by the Honghai Crane when the new crane was completed in 2014, with a lift capacity at 22,000 tonnes.
