On May 2 a critical accident occurred on board of offshore set up vessel Orion 1 on the event of and through crane load checks. The vessel is below development and owned by COSCO (QIDONG) OFFSHORE CO., LTD. The vessel is moored on the quayside on the Liebherr development yard in Rostock, with the crane present process a number of load checks. Reportedly, a number of individuals suffered minor accidents.
The crane has suffered vital harm, whereas harm to the crane and the vessel shall be investigated within the upcoming days and weeks.
The vessel was launched by the top of November 2018 at COSCO Qidong shipyard in China, then sailed to the German port of Rostock to have a 5,000 ton Liebherr crane put in. The growth of the Liebherr HLC 295000 crane was put in by the start of March.
The failure of a wire rope was first given as the reason for the crane growth collapse nevertheless it appeared that the 4 leg hook broke freed from the neck/shaft. The sudden launch of the heavy take a look at load prompted the growth to catapult again over the rear of the crane and crumple. The vessel remained tilted after the accident. However the foundation reason for the accident has but to be confirmed by Liebherr specialists and the investigators.
The Liebherr heavy raise crane sequence (HLC) was specifically designed for the set up of offshore wind generators and the set up and dismantling of offshore installations within the oil and gasoline trade. According to Liebherr the primary function of the HLC sequence is its compact design. The HLC 295000 with an overturning second of 295,000 tm is put in on a base column with solely 16.eight m diameter. The crane thus requires little house on deck and presents the consumer extra cupboard space for the plant elements to be transported and lifted. Despite this small footprint the HLC 295000 may be very “steady” and might raise a payload of 5,000 t at an outreach of greater than 30 m. The HLC 295000 can be utilized for a variety of functions. This mixture of compact design, excessive load capability with giant outreach and low useless weight makes the HLC sequence distinctive.
The vessel was anticipated for supply to DEME NV within the second half of May 2020. Orion 1 was scheduled to begin putting in jacket foundations on the Moray East offshore wind farm positioned off the coast of Scotland as soon as checks and certifications had been accomplished.
