DEME Group has confirmed that a serious accident occurred on 2 May 2020 while testing the 5,000-tonne crane on its newbuild offshore vessel Orion 1
The crane was undergoing load tests at the time. The company said several people were injured but did not provide details. The ship was due to be delivered to the company later in May 2020.
The vessel is currently owned by Cosco (Qidong) Offshore Ltd and was at crane-builder Liebherr’s quayside at Rostock in Germany where the massive crane was installed.
The crane suffered significant damage. Images of the aftermath of the incident suggest the vessel may also have suffered some damage. DEME said the extent of the damage will be investigated in the coming days. Video showing the incident taking place is circulating on social media.
The 145-m long boom for the crane was installed by Liebherr in April 2020 using a specially designed portal crane at Port of Rostock.
The HLC 295000 crane has a maximum lifting capacity of 5,000 tonnes at an outreach of 35 m and a maximum lifting height of in excess of 175 m above the deck of the vessel.
DEME has also been contracted to use the vessel to transport and install the foundations and wind turbines on Ørsted’s Hornsea Two offshore windfarm.
