Fugro was awarded a contract by Van Oord in April and mobilised one of its two Q1400 trenching spreads onto the Van Oord support vessel Jan Steen to execute the export cable burial works. The scope consisted of burying the deeper water sections of two export cables and one connector cable (between the offshore substations), a total combined length of 140 kilometres, to a target depth below seabed level of 1.5 metres. Jetting burial was conducted in seabed conditions consisting mainly of sands with occasional occurrence of harder materials.
Van Oord subsequently added its inter array cable burial scope which will see the spread retained onboard the Jan Steen into Q1 of 2016.
Noting the performance of the Q1400 trenching system, Fugro Project Manager Glenn Munachen said, “Successful completion of this export cable burial reinforces the capability of the trencher on long distance jetting projects as well as its ability to perform projects in harder ground utilising the Q1400 jetting skid.”
