Liebherr-MCCtec Rostock has signed a contract with Aibel for the delivery of a RL 2600-35 Lit cylinder-luffing crane for transmission system operator TenneT’s DolWin epsilon (DolWin5) offshore convertor station
The crane will be used for supply and maintenance on the offshore platform in the German sector of the North Sea. The RL 2600 will be delivered in mid-2021.
The RL 2600-35 Lit is a weight-optimised, compact offshore crane suited to use where space is limited. It has a box boom with a maximum working outreach of 52 m and a maximum lifting capacity of 35 tonnes.
Liebherr said a ram luffing crane is well-suited to small or unmanned platforms and can be electro-hydraulically or diesel-hydraulically powered. The box-type booms the RL series have are a cylinder luffing design. This reduces height and weight and reduces maintenance.
Liebherr sales manager offshore cranes Matti Basan said, “The RL 2600-35 Lit is ready to be equipped with innovative features to meet the demanding requirements of normally unmanned offshore platforms.”
DolWin5 is part of a high voltage direct current offshore grid connection system. It will transmit up to 900 MW of green power and is located in the DolWin cluster. DolWin5 will connect the Borkum Riffgrund 3 windfarm to the grid.
Once the platform is completed, TenneT will use the crane on it to load and unload offshore supply vessels.
