Floating Wind Gets a Lift From New Mooring Tech

Dublin Offshore earns DNV prototype certification for a mooring load reduction device targeting floating wind cost and reliability

13 Mar 2026

Europe’s floating wind sector has gained a notable engineering advance. In February 2026, classification society DNV issued a prototype certificate to Dublin Offshore for a mooring system component designed to reduce the powerful forces acting on floating turbines in deep water.

The device sits directly within a turbine’s mooring line between the seabed anchor and the floating platform. Built from steel and concrete and designed around buoyancy-driven mechanics, it reacts to wave motion by absorbing and redistributing peak loads. By smoothing out these stress spikes, the system reduces strain on both the mooring lines and the anchors that hold floating turbines in place.

That seemingly simple intervention could have wide effects across project economics. Mooring systems are among the most expensive and technically demanding elements of floating wind farms, and they influence the overall cost of energy from a site. A passive device that lowers load requirements without relying on complex active controls offers developers a clearer path toward durable and affordable offshore installations.

DNV granted certification after reviewing structural integrity, operational safety, and load reduction performance under its floating wind standards. The assessment included extensive physical testing at Ireland’s Lir National Ocean Test Facility, where a quarter scale prototype operated for 1,200 hours. The trials captured detailed performance data across harsh Atlantic conditions, including storms such as Hurricane Epsilon and Storm Aiden.

Another advantage lies in the materials themselves. Dublin Offshore’s design relies on widely available steel and concrete, avoiding specialized components that can complicate supply chains. That practical approach could help developers deploy the technology across multiple markets without waiting for new manufacturing capacity.

The company says the next phase will focus on project specific qualification and integration into permanent mooring designs. With independent verification now in hand, Dublin Offshore is positioning the device as a ready tool for engineers planning the next generation of deepwater wind farms.

As European projects move farther into the Atlantic and North Sea, the physics of mooring will increasingly shape what gets built and at what cost. Certified solutions like this one may quietly determine which floating wind projects make it from concept to reality.
