Dismantling work on the offshore crane which was collapsed during load tests onboard the DP3 offshore installation vessel Orion early May, 2020, is going according to plan confirms Liebherr in a press release.
The first components have been safely and successfully recovered. Steel construction work for the repair of the crane has begun.
To salvage of the HLC 29500 with the recovery of the 600-tonne auxiliary jib including jib head, the relevant structural elements were firstly slung and lifted slightly. In this way, the steel ropes were unburdened and could be cut with hydraulic shears.
Using flame cutters the jib head was subsequently removed from the auxiliary jib before both elements were transported to Liebherr-MCCtec Rostock Thereafter, the first sections of the jib centre piece were removed.
“Despite the high complexity of the task the dismantling of the HLC 295000 is going according to plan. Thanks to the first-class technology, modern equipment and our committed team we have achieved our goals on schedule and carried out the work, together with all those involved in the project, under strict safety standards,” said Carl Sarens, Director of Technical Solutions, Projects & Engineering, Sarens.
Especially for this project Sarens works together Marine Salvage Experts from the Netherlands.
In the next phase of the recovery, DEME’s vessel Orion will be shifted to Berth 15 in the international Port of Rostock. The pivot piece and the A-frame of the HLC 295000 will be disassembled there.
The TCC 78000, which is permanently installed in the Port of Rostock, is being used for the secure recovery of these large components. The TCC 78000 was already involved in the assembly of the HLC 295000. The recovery work is expected to be completed by the end of this year.
