Global Offshore has completed its cable installation campaign at Vattenfall’s Danish Kriegers Flak Offshore Wind Farm. The initial phase of work, completed last year, saw Global Offshore utilize its multi-purpose PLP240 pre-lay plough, mobilized on the Havila Jupiter, to carry out route clearance totalling approximately 158km.

The second phase, which commenced in September 2020, included the installation of 72 inter-array cables, utilizing Normand Clipper, and the jet trenching of 72 routes using the Q1400 aboard sister vessel, Normand Cutter. Following the cable installations, the PLP240 returned to the site to conduct backfilling operations, the first operation of its kind on an inter-array grid.
