Green port operations made possible

Major ports play an essential role in enabling global trade by providing efficient operations and focusing on doing so in the most sustainable way possible. As tugs operate daily in busy ports, making green operations possible with a fully electric harbour tug is only logical.

Holland Shipyards Group has developed the EDDY 24-50 E, which is in line with the previously developed revolutionary EDDY TUG series. The EDDY tugs are designed and built around three simple core criteria: safety, performance and economy.


EDDY tugs have a slim hull shape, resulting in 30% lower resistance. Compared to ASD, ATD and RSD tugs, she offers higher stability, safer operations and better performance due to her low staple point and low centre of gravity. For optimum escort tug performance, the EDDY's waterline shape is a winged profile, allowing the vessel to generate lift with the hull and thus generate most escort forces. She sails intuitively and can generate BP in 360 degrees, featuring a thruster at the forward end of the vessel and a thruster aft.

Fully electric

Emission-free operations are not only a great way to work on sustainability, but it also has economic advantages. The OPEX will be significantly reduced over time. This is mainly due to maintenance and fuel and emission savings. All in all, this results in an estimated return on investment of 7 years.

Onshore charging systems have developed rapidly and are based on the vessel's operational profile. Charging the batteries can be done in a few minutes, several times a day, or once a day over a longer period. This all depends on the operational profile.

The electrification of harbour tugs is particularly interesting given that they usually operate in the same area, and charging systems are easily accessible to them.

Frontrunners in electric vessels

Holland Shipyards Group is a frontrunner for developing and building electric vessels. We have delivered several notable projects in recent years, especially in Norway, Germany and the Netherlands, including more than a dozen in the past two years. Most of these vessels are fully electric, such as the recent NZK series for GVB Amsterdam with an innovative shore charging system.
