Dutch wind-assisted ship propulsion specialist Econowind is moving into the deepsea market with the launch of its new 5-series VentoFoil, a larger steel suction wing system for oceangoing vessels. Unveiled last week in Heeg, the 30-metre model is based on the same principles as the company’s successful 3-series wing.

The 5-series targets deepsea owners and operators looking for practical ways to cut fuel consumption and improve regulatory compliance. The launch is the next step for Econowind, after selling more than 150 suction wings across a broad range of vessel types and trades. After gaining traction in shortsea and regional shipping markets, the Dutch company is now setting its sights on larger vessels and longer trading patterns, where the fuel-saving potential of wind-assisted ship propulsion becomes even more compelling

The first 5-series unit will be installed on a Boomsma Shipping vessel this summer, giving the new model its commercial debut. The order also reflects the Dutch shipowner’s continued confidence in VentoFoils as a practical way to reduce fuel consumption and support more sustainable operations.

“As a returning customer, we are pleased to use VentoFoils again on our vessels, now in the form of the 5-series,” said Johan Boomsma of Boomsma Shipping. “Wind propulsion has proven its value both economically and environmentally. With high fuel prices adding to the urgency, this is a logical next step for us. Energy efficiency is high on our agenda, which is why our eight newbuild vessels will be all delivered wind-ready. The first, Frisian Future, will enter service in May.”

To support its move into deepsea shipping, Econowind is also organising production in the Far East, close to where a large share of the world’s new vessels are being built. The aim is to bring manufacturing closer to major shipbuilding hubs and make it easier for owners and yards to integrate the larger VentoFoil units into newbuild projects.

“The 3-series has shown that our technology works in daily operations,” said Chiel de Leeuw, Chief Commercial Officer of Econowind. “With the 5-series, we are bringing that proven concept into the deepsea market.”

The launch underlines Econowind’s view that deepsea shipping is the next growth market for wind-assisted ship propulsion. Econowind’s VentoFoil uses boundary-layer suction technology to generate additional thrust from wind, reducing the power required from the main engine. The company positions the system as a practical and robust solution with limited deck impact, bridge-controlled operation and the ability to tilt the units when required for cargo operations or air-draught limitations.
