The pre-cut trenching workscope on Denmark’s Skagerrak 4 HVDC submarine interconnector project was completed on time, on budget and with zero plough downtime, reports DeepOcean senior project manager David Brown. The independent UK contractor with a penchant for ploughing provided client Statnett & Energinet with the engineering and project management for the project, including pre-trench survey and pre-cut trenching of 23km of the Skagerrak 4 route using the sophisticated APP pre-cut trenching plough (pictured).
