Jumbo, a Dutch group specialising in subsea lifting of large and complex structures and foundations, said it has successfully completed the first phase of work on Energean’s Karish gas field offshore Israel for TechnipFMC, a global leader in energy projects.
Jumbo’s scope of work included transport and installation of 14 suction piles (part of a 14-point FPSO (floating production, storage and offloading mooring system), a tie-in manifold and a 24-inch deepwater gas sales spool.
As part of the mooring spread for the Energean Power FPSO, Jumbo installed 13 suction piles of 176 tonnes each and one weighing 235 tone.
Both the deck layout and the two 900-tonne cranes of Jumbo’s offshore construction vessel Fairplayer were reconfigured to enable each part of the installation, said the statement from Dutch group.
This involved the Fairplayer’s deep-water winches being modified to allow installation work down to 3,000 metres deep.
For the Phase One work, Jumbo had installed the components at a depth of 1,760 m, thus breaking its own deep-water installation record.
The work is scheduled to recommence in 2021, with the hook-up and installation of the Energean Power FPSO, the first FPSO ever to operate in the East Mediterranean.
Joost van der Wiel, Lead Project Engineer at Jumbo, said the installation of the large suction pile was especially challenging and required a specially engineered method in which the pile was first taken down to a depth of 200 m, where it was hung off a Dyneema pennant.
"We then recovered the hook, reconfigured the crane, picked up the pile from the pennant and began the second lift down to 1,760 m deep. That’s a record for us and I am very proud of the team that made this happen," observed der Wiel.
Lauding the Jumbo team, TechnipFMC Project Manager David MacLennan said: "Congratulations on the safe and successful completion of this work scope. It’s been a great team effort.”
Jumbo Project Manager Wieteke Looijschelder said the installation of the tie-in manifold and the 24-inch gas sales SSIV closing spool illustrate Jumbo’s position as a full service T&I contractor.
"The gas sales spool is a flexible piece of equipment, so lifting and lowering it called for a dual lift with a complex rigging arrangement. This technical efficiency is a good example of how our DP2 vessels can handle both the transport and installation needs of a project with just one vessel," she added.
Offshore Construction Manager Barry ten Brinke pointed out that the Karish contract was a multi-disciplinary operation and a unique challenge for Jumbo.
"And, just as with all project completions, its success was driven by a great team onboard and ashore," he added.
Jumbo said it haad paid a lot of attention to the subject of safety during the execution of this contract.
"As well as implementing the highest standards possible, we aim to create an open and communicative atmosphere with respect to safety," noted Looijschelder.
"It is this constructive safety culture that helped us complete the Karish project with zero injuries or incidents," he added.-TradeArabia News Service
