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.
Mike Daniel, Managing Director of Global Offshore said, “We are delighted to report the successful installation of all 72 inter-array cables at Danish Kriegers Flak Offshore Wind Farm. Despite COVID-19 restrictions and the associated challenges, extreme weather, and complex seabed conditions, our expert teams have met client expectations and completed this project safely, in under six months.”
Prior to the commencement of the second phase, Global Offshore upgraded the Normand Clipper for power cable work. With the addition of a 4,000-tonne cable carousel, two 15-tonne cable tensioners, a 25-tonne quadrant deployment frame and a fully integrated control system, the 127.5m cable-laying vessel enable Global Offshore to continue providing a flexible, efficient and reliable service for its clients despite the COVID-19 pandemic, with the extensive operational challenges this has created.
Ian Bremner, Project Director at Vattenfall said, “Global Marine Group has shown professionalism in their operations and solution-oriented thinking, delivering a high standard of engineering to deal with the technical challenges during work execution. Our partner has worked safely throughout the COVID-19 pandemic alongside other ongoing site operations, contractors and the Vattenfall project team.”
