Jumbo to install 126 gravity anchors in deep water

Jumbo has been awarded a contract by Malaysian pipelay contractor, Sigur Ros. Under the contract Jumbo, with the HLV Fairplayer will oversee transportation and installation of 126 gravity anchor spreads in water depths up to 1,400m, starting end 2013-beginning 2014.

Project management and engineering will be carried out by Jumbo, which will also undertake collection of the materials in the port of Mersin Tasucu Seka in Turkey and transportation to the offshore location and installation.

The anchor spreads, which will consist of a 230t gravity anchor, tether wire and subsea buoy will be used to moor a pipeline with a 1,600mm diameter, running 80km from Turkey to Northern Cyprus. The pipeline, in spans of approximately 500m, will be suspended, floating at a depth of approximately 250m.
The tether ropes, 116mm in diameter, will be cut to varying lengths to match water depths along the pipeline’s route, up to 1,400m. Towards the tops of the tether wires the sub-sea buoys, 8m in length, 3m in diameter and weighing 17t each, will be positioned to moor the pipeline.
