The Liebherr heavy lift crane series (HLC) was specially designed for the installation of offshore wind turbines as well as the dismantling of offshore installations in the oil and gas industry.
Unfortunately, the HLC 295000 was severely damaged following an accident in the Port of Rostock.
Liebherr has contracted Sarens to carry out the salvaging works for the HLC 295000 in the Port of Rostock, Germany and it will be carried out in a few phases:
- Securing of the demised HLC 295000 on the vessel to allow its movement to a different berth.
- Recovery of the components prior to the dismantling of the crane.
Sarens has deployed numerous units of cranes to assist in the recovery, including:
- 1 unit of 1,350-tonne LR 11350 crawler
- 3 units of 750-tonne LR 1750 crawler
- 1 unit of 150-tonne LG 1150 lattice-boom truck crane
- 1 unit of 500-tonne LTM 1500-8.1 mobile crane
- 1 unit of 200-tonne LTM 1200-5.1 mobile crane
- 1 unit of 60-tonne LTL 1060 truck crane
- SPMT axle-lines
Liebherr has also used their own TCC 78000 together with Sarens’ LR 11350 for the tandem removal of the HLC slewing ring.
Frank Busse, Technical Advisor in Customer Service for Offshore Cranes at Liebherr-MCCtec Rostock GmbH said about the execution: “Our thanks go to all those involved. The safe and trouble-free salvage work was only possible due to the excellent teamwork between Sarens, the contractor for the recovery work, the authorities involved, and our specialists from the Liebherr salvage team.”
With a lifting capacity of up to 5000T at an outreach of 35 meters and a maximum lifting height of 175 meters above deck, the HLC 295000 is the largest offshore crane Liebherr has ever manufactured and is expected to be completed by the end of this year.
