Transport engineering and heavy lift specialist Mammoet will assist fellow Dutch firm Heerema Marine Contractors with the installation of two giant topsides for TenneT’s 2 GW offshore platforms project.
HLPFI reported at the beginning of the year that Heerema had signed a contract with TenneT for the delivery of a new float-over barge for the project. Mammoet will help to prepare the pair of giant topsides for floatover operations by skidding the topsides from a heavy transport vessel to the Heerema H-731 barge, using hydraulic skid shoes.
After the skid-over operation, Mammoet’s Mega Jack system will lift the topsides to the designated floatover height onboard the H-731. A deck support frame will then be pulled beneath the topsides to allow for their final installation onto jacket foundations.
TenneT’s 2 GW programme will provide 14 high-voltage direct current (HVDC) offshore grid connection systems, each with a capacity of 2 GW, installed in the North Sea by 2032 – with six in Germany and eight in the Netherlands. The HVDC systems receive and send ashore power generated by wind farms in the North Sea, converting this power from AC to DC.
“With this contract, Mammoet will be playing a key role in securing the future of energy in Northern Europe while showcasing our unique capabilities in both high-precision skidding and jacking operations,” said Richard Verhoeff, sales director at Mammoet.
Last week, HLPFI reported that Mammoet had been busy with a trio of projects across Australia, spanning several sectors.
