Global Offshore completes Kriegers Flak cable installation campaign
Global Offshore has completed their cable installation campaign at Vattenfall’s Danish Kriegers Flak Offshore Wind Farm. The initial phase of work, completed last year, saw Global Offshore utilise their multi-purpose PLP240 pre-lay plough, mobilised 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, utilising 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 site to conduct backfilling operations, the first operation of its kind on an inter-array grid.
Prior to the commencement of the second phase, Global Offshore upgraded the Normand Clipper for power cable work. With the addition of a 4,000t cable carousel, two 15t cable tensioners, a 25t quadrant deployment frame and a fully integrated control system, the 127.5m cable-laying vessel enables Global Offshore to continue providing a flexible, efficient and reliable service for their clients despite the COVID-19 pandemic, with the extensive operational challenges this has created. Mike Daniel, Managing Director of Global Offshore says, “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.” Ian Bremner, Project Director at Vattenfallm, states, “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.”
