DeepOcean 1 UK Ltd, a subsidiary of DeepOcean Group Holding BV (DeepOcean), has been awarded a contract for the provision of post-lay trenching of a 42km power cable from the shore to offshore the United Arabic Emirates. Work will be performed by DeepOcean’s recently upgraded T1 mechanical trencher.
The T1 is a 25 tonne self-loading wheel cutter capable of trenching small diameter cables to 20in pipelines in water depths from 0-500m and in soil conditions from loose sands to 40MPa cemented calcarenite. DeepOcean has recently modified T1’s power and cooling system to deliver a cost efficient onshore, shallow and deep water trenching solution that boast an impressive track record having trenched over 1,650km of subsea product to date.
Modifications to T1 were performed in the UK and included trialling the trencher in various soil conditions up to 40MPa with trench depth of 1.2 meters achieved. The T1 was subsequently transported to Abu Dhabi were further successful onshore trials were conducted to test the T1’s cooling system in the regions extreme temperatures. The post-lay trenching works have now commenced offshore Abu Dhabi.
