Key Points
- Strategic Innovation: A new 30-meter steel “wind wing” prototype is under construction in Heeg to reduce maritime fuel consumption.
- Cost Efficiency: The technology offers a projected 10% to 20% savings on fuel costs and mitigates emerging carbon emission taxes.
- Market Scalability: Supported by the European W4S project, the technology targets a potential market of 30,000 seagoing vessels worldwide.
In the Dutch town of Heeg, the maritime sector is taking a significant industrial leap toward decarbonization, leveraging one of the oldest power sources in shipping history: the wind. Developers are currently constructing a massive prototype of a metal “wind wing” designed to drastically reduce fuel consumption and operational costs for commercial shipping fleets.
While smaller vessels already utilize similar wind-assist technologies, the project in Heeg represents a substantial scaling up of the concept. The new prototype stands 30 meters tall and 27 meters wide. Unlike previous iterations constructed from aluminum, this massive structure is being built from steel.
Upon completion, the prototype is scheduled for installation on a coaster—a small merchant vessel—operated by Boomsma Shipping, based in Sneek. The project is being commissioned by Tjeerd Wiebe Bijlsma of Bijlsma Marine Services in Warten, who views the technology as a critical tool for modernizing commercial fleets.
The Economic Case for Wind Propulsion
For shipping companies, the adoption of wind wing technology is driven by balance sheet considerations as much as environmental compliance. The primary financial incentives include direct reductions in fuel expenditure and the avoidance of increasingly stringent levies on shipping emissions.
According to industry projections, the system can deliver fuel savings between 10% and 20%. Furthermore, as regulators move to tax maritime CO2 output, technologies that lower a ship’s carbon footprint are becoming essential near-term investments for fleet owners.
Tjeerd Wiebe Bijlsma explained the mechanics and the power output of the system, noting that similar principles are already in use on a smaller scale globally:
At this moment, there are several dozen smaller coasters worldwide sailing with such wings. The principle is similar to an airplane wing. Due to the round shape of the wing, overpressure is created on one side and underpressure on the other.

Bijlsma detailed the operational impact of this aerodynamic design, stating that the pressure difference creates propulsion that helps the ship move forward.
He quantified the system’s thrust capability as comparable to the power of ten mid-class cars.
European Collaboration and Market Potential
The development in Heeg is part of a broader cross-border initiative. The European Interregional North-West Europe (NWE) project, known as Wind for Shipping (W4S), coordinates efforts between regions in Germany, France, and the Netherlands. The consortium aims to further develop the technology and scale up production capabilities to meet industrial demand.
The addressable market for this technology is vast. Provincial estimates suggest that approximately 30,000 seagoing vessels worldwide are suitable candidates for retrofitting or equipping with this wind-assist technology, presenting a major opportunity for the European maritime manufacturing sector.
