 Recently, the Dutch company Tetrahedron (tetrahedron) has developed a new type of crane that can hoist the next generation of large offshore wind turbines. The crane can be installed on the original installation ship for upgrading. Change the old look to the new one, save trouble and money!<br style="color: rgba(0, 0, 0, 0.87); font-family: "Roboto&quot:undefined;,arial,sans-serif:undefined; font-size: 18px; font-style: normal; font-variant: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-decoration: none; text-indent: 0px; text-transform: none; -webkit-text-stroke-width: 0px; white-space: pre-wrap; word-spacing: 0px"/>Like the company's name, the new crane has a tetrahedral shape. According to Tetrahedron, the new type of crane has a stronger lifting capacity than existing ship-borne cranes with the same floor area, because it uses different motion principles and structural load transfer methods. 


They proudly said that if the existing jack-up platform ships are replaced with their cranes, they will be able to hoist larger offshore wind turbines in the future, which can meet the maximum 20MW wind turbine installation. In this way, the existing ships can be fully utilized and the cost of upgrading to a large crane ship can be saved.


At present, DNV GL has completed the concept design verification and plans to deliver the first new crane in Rotterdam before 2022. Tetrahedron founder and director Wilco Stavenuiter said: "Due to its unique design and patented technology, this crane is only 50m higher than the existing crane without adding any weight or complexity."
"In this way, the jack-up platform originally designed to install the 5MW wind turbine can be upgraded without re-strengthening the hull (because the new crane exerts a small torque on the jack-up platform), and can install the currently developed SG 14-222 DD or GE Haliade-X super-large wind turbine."
The development of this crane was funded by a cooperative project initiated by the Dutch Enterprise Agency (RVO), which includes Van Oord, Delft University of Technology and a number of industry suppliers.
