The EDDY 30 concept has been developed to provide a viable and attractive alternative to a large number of existing tug designs. The Bollard Pull performance has been determined based on requirements from modern ports based around the globe.
With indirect line pull forces of over 120 tons, the hull shape of the EDDY 30 design allows for excellent indirect towing performance, and can be certified as an escort tug. In combination with the SafeWinch or a Render-Recovery winch the design rivals its sometimes much larger competitors.
The spacious engine room lay-out allows for additional equipment and systems, such as an oil spill response or Fifi-1 installation. Also the hull allows for more installed power, giving a higher Bollard Pull performance.

To reach the indicated Bollard Pull of 65 tons, the EDDY 30 design has over 4.100 kW installed power, of which 920 kW is delivered through the electrical motors which are mounted on the thrusters. These electrical motors alone, already deliver a Bollard Pull performance of 23 tons!
This diesel-electric setup allows for very precise manoeuvring and an effective low-power operational range, which reduces fuel consumption and emissions during free sailing, idle or passive assist operations. Additionally, the propulsion allows for reverse thrust, which effectively means that the rotation of the propeller can be reversed, further increasing manoeuvrability.
With a spacious MLC-approved accommodation for 7 persons, a large open bridge, spacious working decks, walkways and engine rooms, crew comfort and safety has been a priority throughout the engineering process, which is clearly visible in the end-product.
