Mammoet has assembled its PTC210-DS ring crane in Rotterdam for use in refitting two offshore wind vessels.
The 210,000tm crane has a maximum lift capacity of 3200t is one of the largest in the company’s fleet. It will be used to perform crane replacements on two offshore wind installation jackups, Wind Orca and Wind Osprey, for Cadeler.
The PTC210-DS will be used to remove the existing leg cranes from both vessels and replace them with new GustoMSC high-capacity ones. GustoMSC has been contracted by Cadeler to design, fabricate, deliver, and install the cranes.
The new leg cranes are fully electric driven and have a 1600t lifting capacity, making them ready to install and service next-generation wind turbines with capacity ratings exceeding 14MW.
The replacement work on Wind Orca and Wind Osprey is scheduled to commence in the third quarter of 2023 and is expected to be completed by the first quarter of 2024.
Dirk Knoester, Senior Adviser at Mammoet, said: “The PTC210-DS is the perfect crane for this job. It has a relatively small footprint combined with 360-degree slewing, and the possibility to switch between fixed and luffing jib mode (as only the PTCs can) resulting in the largest possible working area.
“These PTC cranes can also be assembled in numerous configurations and thus a tailor-made configuration is feasible for any job: different mainboom and jib lengths, fixed or luffing jib, different amounts of counterweight, and two ring diameters.”
