A cardinal discipline for safe transportation of project cargo for wind turbines at sea. OSK-Offshore are specialists within seafastening design and have been involved in numerous seafastening projects. Our seafastening service comprises designs and calculations on local reinforcements, cradles and grillages for transportation of any project-related component type, e.g. wind turbine nacelles, blades, towers, monopiles, transition pieces, jackets, cranes, pile driving hammers, topsides, A-frames, ROVs etc.

By use of FEM (Finite Element Model) analysis, we can determine the stresses and deformations in the support structures, and we apply our expertise in the development and refining of the seafastening design hence keeping the use of steel to a minimum benefitting the client.

Our engineers provide expert consultancy on a range of seafastening disciplines and areas.
