Supporting silent monopile installation: Vibrojet® Quick Disconnect Couplings

Last year, we had the opportunity to collaborate with GBM Works on the development of a Quick Disconnect Couplings for the Vibrojet® project. The Vibrojet® is an installation method developed by GBM Works to silently install large monopiles for offshore wind farms. The method consists of a jetting system that will fluidise the soil inside the monopile. This reduces overall friction between the pile and the soil, allowing driving with a vibratory hammer instead of a traditional impact hammer. The equipment from SubseaDesign will be part of the Vibrojet® solution to be delivered for the Hollandse Kust West wind farm project, developed by Ecowende. The couplings will be used to connect 4 feeder hoses to the permanent pipework on 3 monopiles. Once pile driving is completed, the couplings shall be quickly and reliably disconnected by a remotely operated mechanism. The project was executed in three main phases: design and engineering started in 2024 followed by prototype testing and concluded with final delivery in the fall of 2025. Close collaboration throughout all phases ensured smooth progression from concept to completed delivery. Further details will be shared in the next post, where we will take a closer look at the development and testing activities carried out both at SubseaDesign’s facilities and during onshore testing at the yard in Amsterdam.
