After having been awarded the project last December 2016 by Hyundai Heavy Industries Co. Ltd (HHI), Jan De Nul Group’s preparations for the subsea cable laying work for ADMA-OPCO’s NASR Full Field Development Package 2 Project off the coast of Abu Dhabi in the Arabian Gulf are in full swing. The preparations are lead from Jan De Nul Group’s office in Abu Dhabi by a dedicated team of project management and project engineers.
The offshore work scope involves the cable installation services of three 132kV subsea power cables and ten 11kV subsea power cables, totaling over 200 km of cable. Jan De Nul Group is mobilizing its cable laying vessel Isaac Newton to perform the loading, transport and laying of the cables. Thanks to its large carrying capacity, the Isaac Newton is able to install all 200 km of cables in 2 trips only. The first cable sections will be loaded at Nexans’ facilities in Norway as of 10th October 2017.
The cable protection works, which comprise of pre- and post-lay mattress installation, post-lay trenching and subsea gravel installation, will be performed by Jan De Nul Group’s multipurpose vessel Daniel Bernoulli. This will be the first project for the Daniel Bernoulli, following its recent delivery from the shipyard in China. The cable routes will cross existing assets at more than 50 locations, involving installation of approximately 700 concrete mattresses. About 60km of the cable routes require burial, of which a substantial portion goes into calcarenite rock.
All offshore works are planned to be executed between the fourth quarter of 2017 and the second quarter of 2018.
