Mammoet has completed the assembly of its PTC210-DS ring crane in Rotterdam for a heavy-lift project for GustoMSC.
The PTC210-DS ring crane is one of the largest in the global engineered heavy-lifting specialist’s fleet and will be used to perform crane replacements on two offshore wind installation jack-up vessels – Wind Orca and Wind Osprey – for the shipping and construction company Cadeler.
The PTC210-DS will be used to remove the existing leg cranes from both jack-up vessels and replace them with new GustoMSC high-capacity machines. The new leg cranes are fully electric and possess a 1600-tonne lifting capacity, specifically designed for the installation and service of next-generation wind turbines with capacity ratings exceeding 14MW. Senior Advisor at Mammoet Dirk Knoester labelled the PTC210-DS as the “perfect crane” for the job GustoMSC has outlined after it was contracted by Cadeler to design, fabricate, deliver, and install the cranes.
“It (the PTC210-DS) has a relatively small footprint combined with 360-degree slewing,” he said. “The crane also has the possibility to switch between fixed and luffing jib mode resulting in the largest possible working area.”
The giant ring crane is one of five 5000-tonne class ring cranes in Mammoet’s fleet and is the only one operating in Europe at the moment after sending three of its PTC ring cranes over to India to work on the energy industry removing heavy refinery components. The crane holds a maximum lifting capacity of 3200 tonnes can lift at 210,000 torque-metres.
The PTC cranes are capable of being assembled in numerous configurations and can be very easily adjusted according to Mammoet, thus enhancing their flexibility. After the assembly of the crane in Mammoet’s Schiedam yard, Senior Commercial Manager at Mammoet Remco Zandstra highlighted the “safety and optimisation” of GustoMSC’s schedule as the reason behind constructing the crane in Rotterdam.
“Our yard has a unique location in the port of Rotterdam, and this gave us the possibility to position the crane between the two vessels and serve them at the same time,” he said. “Not only does this save considerable time, by minimizing movements of cranes in the yard and vessels along the quay, it also creates the safest possible solution to perform this project.”
The replacement work on Wind Orca and Wind Osprey is scheduled to commence in Q3 2023 and is expected to be completed by Q1 2024.
