WINGSAIL

Lightweight and Durable Solution for Enhanced Container Ship Operations

Our Rigid Elevator Wingsail (OW RE) is fit for purpose for Container ships. It offers industry-leading upwind performance and thrust-to-weight ratio, and delivers double-digit fuel and emission savings.

Its unique, proprietary and compact Elevator system streamlines port operations and minimizes loss of cargo space (<1%).

Seamless Integration & compatibility with Port Operations

Specifically tailored for the large fleet of container ships, our Rigid Elevator Wingsail (OW RE) optimizes loading and unloading operations, by elevating up or down the wingsails.

Whether you're retrofitting an existing vessel or working on a newbuild project, the modular, lightweight, low center of gravity ensures an easy integration for ship designers and shipyards, with no compromise on the cargo space (<1% loss of TEU) and stability.

The Rigid Elevator Wingsail (OW RE) is built to be robust and low-maintenance, with an expected lifespan of 25 years.

High-Performance Agility

In terms of performance, operations, and maintenance, the Rigid Elevated Wingsail (OW RE) offers 1.3 tonnes per day fuel saving in average and is particularly adapted with transocean transit voyages. Based on IMO data, for a ship sailing at 16 knots, 87% of the global trading routes exhibit apparent wind angles lower than 75°. This shows that Wind Assistance only makes sense if it produces thrust with headwind.

As such, our 2-element variable camber system differentiates by its thin and aerodynamic profile which generates positive thrust starting at 5° apparent wind angle. This agility is an essential feature for Container ships usually sailing at high speed.
