De-armoring cables : Medium Voltage & Fibre Optic Termination & Testing : 12 Hour Working
Northwester 2 is a 219MW offshore wind farm in the North Sea, off the coast of Ostend in Belgium. H&Askham was awarded the Testing and Termination Scope for Northwester 2, assigned by NSW, a subsidiary of General Cable, which recently became part of Prysmian Group.
H&A deployed highly experienced offshore teams consisting of Medium Voltage jointers, fibre optic technicians, cable mates, testing technicians, tools and equipment, as well as supporting management and logistical personnel, to complete the preparation, installation and testing of Northwester 2 subsea cables.

"Our expert teams work with major organisations in the power & energy sectors, delivering high voltage solutions all over the world."
The subsea cable installation of Northwester 2 was separated into two main phases. During the first phase, the cable installation contractor installed the cables, including temporary hand-offs and temporary cable supports.
The second phase, which was part of the H&Askham scope, consisted of de-armoring and preparing the cables, installing the permanent cable hang-offs, routing the Medium Voltage cable cores to the switchgear, termination of the Medium Voltage cable cores, splicing the optical fibres and testing of both power and optical cables. There were three sizes of 36Kv array cables used on the project, XLPE aluminium conductors 800mm2, 500mm2and 240mm2.
H&Aaskham work scope on Northwester 2 was completed between December 2019 and May 2020.
