GBM Works has announced today the successful delivery of the first of three Jetrings for the Vibrojet® system that will be used to silently install some of the monopiles of the wind turbines at Ecowende’s Hollandse Kust West VI offshore wind farm.
The water jets hosted by the jetring fluidize the soil during vibrohammer installation, thereby reducing pile friction. This means the probability that a conventional impact hammer is needed is also reduced. The ultimate goal is to limit noise during the construction phase and disturb marine life as little as possible.
The remaining two rings are on track for delivery in the coming weeks to Sif Group in Roermond. Sif is the manufacturer of the monopiles for Ecowende. Once received, Sif will incorporate the rings seamlessly into the production line of the monopiles. Following integration, the jetting components will undergo rigorous pressure testing by GBM Works at the Sif yard on the Maasvlakte in June 2025.
Albart Barents, Project Manager at GBM Works, reflects: “I am excited to announce the successful delivery of our first Jetring! This significant milestone was made possible by the incredible efforts of our team, subcontractors KCI and KERSTEN and Ecowende. Onward to the next steps in making this project a major success. We’re proud to collaborate with Sif and contribute to Ecowende’s vision of teaming up with nature to build the most environmentally friendly windfarm to date. Together, we’re pushing the boundaries of innovation and sustainability in offshore construction and leading the way for affordable, sustainable and responsible offshore energy.”
Joe Haley, Foundation Innovation Lead at Ecowende, adds: “The delivery of the first Jetring is a major step forward for vibrojetting, and the aim of reducing offshore construction noise on our project. It is an exciting start to the year; this is the first of many milestones in 2025! Bringing the Jeting from the drawing board into reality has taken a united team effort with GBM Works, Kersten, KCI, Ramboll, SIF and Ecowende – congratulations to the teams involved.”
