With extensive experience in the design and fabrication of seafastening structures, TWD is able to deliver reliable and cost effective seafastening for the safe transportation of equipment on vessels and barges. We are able to create practical seafastening with effective deck interfaces and verify the deck strength capacity. The TWD project team works in close co-operation with the client to satisfy the requirements for functionality and placement on deck. Various examples include seafastening of Monopiles, Transition Pieces, Jackets, Cranes, Pile driving hammers, Topsides, A-frames and ROV’s. To see one of the more advanced and alternative seafastening solutions, take a look at the constraining of a jacket by means of suction buckets.
The relatively thin buckets were clamped in order to avoid welding and have a very quick release offshore. Watch the video.
At this very moment, the Vole au Vent has installed the final WTGs for the Bligh Bank 2 project of the entire 51 windmills. For this ongoing installation project, we supported Jan De Nul with designs and know-how for seafastening and installation of all WTG components. TWD assisted Jan De Nul already at an earlier stage during the Bligh Bank 2 OWF installation. In June 2016, their jack-up vessel Vole au Vent set sail with re-used seafastening structures, formerly designed and later on modified by TWD.
As offshore wind turbines and their foundations become ever larger, contractors across the industry face growing challenges with their vessels’ limited capacities. To stay efficient and competitive with their current fleets, they require innovative installation concepts and daring engineering solutions.
