Jan De Nul installs 204 km of cable at ADNOC’s NASR offshore oil field

Jan De Nul Group has completed the cable installation scope for the Phase II Full Field Development at ADNOC’s NASR offshore oil field.

Jan De Nul Group was subcontracted by Hyundai Heavy Industries for the cable loading, transport, laying and protection of three 132kV subsea power cables (total length 147km) and ten 11kV subsea power cables (total length 57km).

The NASR oil field is located approximately 130km northwest of Abu Dhabi and the project is part of the ADNOC plan to boost the field’s production to 65,000 barrels per day.

A total of 204 kilometers of cable was loaded in Norway, and transported and installed at the project site in two separate trips with the Cable Laying Vessel Isaac Newton.

Jan De Nul said on Tuesday that it had used its Isaac Newton cable layer for the job, adding it had managed to install the longest and heaviest of all thirteen cables, being the 71km long and almost 6,000 tons heavy 132kV cable between Das Island and the NASR field, in a single length.

Apart from the Isaac Newton vessel, Jan De Nul used the Multi-Purpose Vessel Daniel Bernoulli to carry out full cable protection scope including 53km of post-lay trenching, the installation of 671 concrete mattresses as well as 8km of rock berm installation.
