Jumbo Completes Karish FPSO Suction Piles Installation
On behalf of TechnipFMC, Jumbo Offshore successfully completed the first phase of work on Energean’s Karish gas field offshore Israel in October. Jumbo’s scope of work included transport and installation of 14 suction piles, part of a 14-point FPSO mooring system, a tie-in manifold and a 24 inch deepwater gas sales spool. Jumbo installed the components at a depth of 1,760 metres, breaking its own deep-water installation record. Jumbo’s 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
Installing 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. This involved the Fairplayer’s deep-water winches being modified to allow installation work down to 3,000 metres deep.
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, continues Jumbo Project Manager Wieteke Looijschelder. “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.”
