Innovative ECOaster Vessel Design Ready For Methanol Use Gets Approval From DNV

DNV, a reputable international classification body, has granted Approval in Principle (AIP) to an innovative ECOaster vessel design ready for methanol use. The creative ECOaster idea was created in Germany’s Oldenburg with Fehn Ship Management, HB Hunte Engineering, Reederei Rörd Braren, and Claus Rodenberg Waldkontor.

With the completion of a comprehensive analysis by DNV and an extensive approval process, the AIP represents a significant step towards completing the ECOaster project.

This eco-friendly ship is intended to be a general cargo adaptable ship that can carry project, general, and bulk cargo. Predictions from the Hamburgische Schiffbau-Versuchsanstalt indicate a 10% reduction in fuel consumption compared to conventional vessels of similar size, making it noteworthy for its deficient fuel consumption and emissions.

The improved hull design and high-performance propulsion system, which can operate on methanol as a substitute fuel source, are the sources of the efficiency gains. To further improve its environmental credentials, the ECOaster plans to incorporate a Flettner rotor that uses wind power to increase propulsion and reduce fuel consumption.

With a length of 115 meters and a design suitable for Ice Class 1B, ECOaster can reach a top of twelve knots speed and carry cargo weighing 6,000 tons. The ship’s large open deck, with the bridge in the front, makes it possible to transport long goods without restriction. The ECOaster’s continuous cargo deck, divided by portable bulkheads, increases its range of uses.

ECOaster’s adherence to rules set forth by the International Maritime Organization, including the International Code of Safety for Ships Utilizing Gases or Other Low-flashpoint Fuels and the Interim Guidelines for the Safety of Ships using Methyl/Ethyl as Fuel, is validated by DNV’s AIP.

During the stringent approval procedure, DNV examined not only the general arrangement plan and hazardous gas area plan, which provide basic information about the vessel but also the detailed diagrams of the ventilation and Low-Flashpoint Liquid (LFL) fuel systems, which following the safety concept that the engine supplier has approved.

The ECOaster is positioned as a feasible and viable option in the marine sector because of its methanol-ready design and environmentally friendly attributes.
