Jumbo Offshore to Install Protection Structures

Wednesday, April 27, 2011

In June 2011, Jumbo’s DP2 Offshore Heavy Lift Vessel Fairplayer will install 4 subsea protection structures for production flowlines at 600 m water depth in the Laggan & Tormore fields. These gas condensate fields, owned by Total and Dong Energy, are located 125 km north-west of the Shetland Islands. This region contains approx. 17% of the remaining UK oil and gas reserves. The subcontract, commissioned by client Allseas, will combine transport and installation, Jumbo Offshore’s hallmark.

The fields’ subsea production and pipeline system is the deepest system in UK waters and includes two 18-inch production flowlines. The flowlines will connect the subsea production facilities to the onshore processing terminal at Sullom Voe (Shetland). The two flowlines require protection structures at the Tormore starting point and at the Laggan tie-in location.

Scope of work
HLV Fairplayer will mobilize in Rotterdam (The Netherlands), e.g. taking temporary accommodation units onboard (max. 65 persons) and preparing its Deepwater Deployment System (DDS). The four structures (composed of six elements) vary in weight from 180 t to 270 t and measure 38 x 21 x 6 m. Fairplayer will make two consecutive trips. Each trip Jumbo will transport and install two structures in three lifts. Using its DDS, the structures will be installed at 600 m water depth in a single voyage.

Lift, ship, install: all in one go
The Laggan & Tormore subsea installation project confirms Jumbo Offshore’s ‘added-value concept’ of providing a single solution for loading, transporting and installing subsea structures in water depths up to 3,000 m. Once again, Fairplayer’s DP2 capabilities, Deepwater Deployment System and twin 900 t mast cranes prove to be constructive to a high-technology offshore project.

After project completion Jumbo plans to keep HLV Fairplayer in the North Sea area for other installation opportunities.
