One of Jumbo’s heavy lift & installation vessels, the Fairplayer, is in Rotterdam preparing for a subsea installation project. Jumbo’s Fairplayer will be executing the installation of the mooring spread for the EnQuest Producer FPSO. This FPSO will be operating at the Alma and Galia fields, located in Blocks 30/24, 30/25 and 30/29, 310km south-east of Aberdeen in the UK North Sea.
Jumbo’s Fairplayer will utilize her enormous hold and the two onboard 900t mast cranes for the installation. All additional equipment, such as the pile driving template and hammer and ROVs will be placed on board during mobilisation. After mobilisation the vessel will only be making two voyages to the offshore location.
The first voyage Jumbo transports the anchor piles and bottom chains to the field. There, the Fairplayer installs the anchor piles making use of the template, hammer and ROVs. After that the bottom chains are pre-tensioned and laid out on the seabed. For the second voyage the vessel loads several reels with spiral strand wire and the top chains. In the offshore field the Fairplayer’s crew connects the chain and wire and situates them on the seabed to be picked up for the FPSO hook up.
Scope of work
Jumbo is the main contractor for the EnQuest Producer installation project. The complete project scope consists out of the fabrication of the anchor piles, the mooring spread installation and FPSO tow out and hook up. Jumbo subcontracted the tow out and hook up to Boskalis Offshore.
The Fairplayer and her sister vessel Jumbo Javelin are two of Jumbo’s four J1800-class heavy lift vessels. During the past years these vessels have proven their value to Jumbo’s (offshore) clients, because they are ideal for combined transport and offshore installation projects. This makes double handling superfluous; there’s no need for barge-tug combinations and other crane vessels, thus reducing the number of load- transfers and consequently the number of risks.
