DROMEC supplies new winch system for research vessel Zirfaea of Rijkswaterstaat

Rijkswaterstaat requires millions of cubic meters of sand each year to maintain and protect the Dutch coastline from erosion caused by heavy storms. For this offshore sand extraction, a dredging permit is required, which must be supported by an environmental impact assessment. On behalf of Rijkswaterstaat, eighty areas will be assessed for their suitability for the extraction of nourishment and fill sand over the next ten years. Using the research vessel Zirfaea, Rijkswaterstaat conducts surveys between the -20 meter NAP depth line and the 12-mile zone. During this research, various seabed ploughs are used. For operating these ploughs, Rijkswaterstaat utilizes a DROMEC winch system.

Winch system

On this existing vessel, which was built in 1993 at Bodewes in Foxhol, a new winch system has been installed. With this winch—operating with an adjustable constant tension—the Zirfaea tows a seabed plough across the seafloor. This new winch system uses electric drives: environmentally friendly and aimed at sustainability. Additionally, an auxiliary winch has been installed for lowering and hoisting the seabed plough.

10ft Container

The entire winch system is housed in a 10ft container. This compact configuration makes it multifunctional and usable on other Rijkswaterstaat vessels. DROMEC’s engineers have collaborated with the government on this project, given that multiple vessels can operate with this container size.

Roelof, Sales at DROMEC:

“We received the request for this winch system from Damen Maaskant Stellendam on behalf of Rijkswaterstaat. We had excellent communication throughout the development and enjoyed the smooth cooperation during installation. With this project, we are contributing to a safe and clean coastline!”
