RL 2600 crane shipped for DolWin epsilon platform

Rostock (Germany) – The Liebherr crane was shipped to Singapore on 27 December 2022 and installation on the DolWin epsilon platform is planned for March. The DolWin5 platform is scheduled to enter service in 2024. The RL 2600-35 Litronic is a weight-optimised and compact designed offshore crane. The cylinder-luffing crane is the ideal equipment for small platforms, where space is limited. The RL 2600 has a box boom with a maximum working radius of 52 metres and a maximum lifting capacity of up to 35 tonnes.

“With the delivery of the RL 2600, we conclude a successful cooperation with Aibel and TenneT and enable highly efficient and reliable operation of the offshore converter platforms, which is particularly important in times of the energy transition,” comments Matti Basan, Senior Sales Manager for Liebherr Offshore Cranes. “We are confident about the future and expect more projects to be launched in the offshore wind sector. Our goal is to continue to play a leading role in the development and supply of crane solutions for the offshore industry,” Basan adds.

The RL 2600 is the first crane for TenneT to be equipped with a Master V control system, which was developed for the latest maintenance systems such as LiMain. Despite difficult circumstances during the production period, in the middle of the COVID phase, the crane was delivered on time.

“We are very happy to have an experienced and reliable partner on board with Liebherr. As with previous projects, Liebherr has been very cooperative and the RL-cranes are at the top level in their segment, both technically and in terms of quality,” states Martin Lundgren, Aibel AS Project Procurement Manager DolWin5.

The DolWin5 project – 900 MW from three wind parks

The associated offshore platform DolWin epsilon converts the three-phase current produced by wind turbines into direct current. From there, a 100 km long submarine cable runs in a southerly direction past the island of Borkum in the west to the landing point in East Frisia. On land, the electricity is transported 30 km further to the onshore converter station and converted back into three-phase current, ultimately being fed into the extra-high voltage grid via the transformer station. Due to the distance and the power to be transmitted, direct current is suitable for low-loss transport.
