SCHOTTEL HAS BEEN AWARDED A CONTRACT TO DELIVER SCHOTTEL ECOPELLERS AND PUMPJETS FOR TWO NEW AUTONOMOUS RO-RO VESSELS. THEY WILL BE OPERATED BY ASKO MARITIME, NORWAY’S LARGEST GROCERY WHOLESALER, AND THEY WILL BE BUILT AT COCHIN SHIPYARD (CSL) IN INDIA. BOTH VESSELS WILL HAVE FULL BATTERY-ELECTRIC PROPULSION AND ARE DESIGNED FOR TRANSPORTING TRAILERS ACROSS OSLO FJORD BETWEEN TWO OF ASKO’S DISTRIBUTION CENTRES.

Kai Just Olsen, Director of ASKO Maritme, shares, “We have a clear ambiton to be climate neutral and have set ambitous goals, including being a self-sufcient provider of clean energy and having 100% emission-free transport by 2026. These innovatve ships are key to fulflling that ambiton and will form an essental component of a zero-emissions logistcs chain linking our facilites. We are very pleased that Schotel is supportng us in this project.”
Vessels for transporting trailers across Oslo Fjord between two of ASKO’s distribution centres.
The main propulsion system of each vessel consists of one medium sized EcoPeller typeSRE 210 (500kW) driven by an electric motor. A PumpJet type SPJ 57 (200kW) will be ftted at the bow to act both as thruster and take-home system.
High-effciency EcoPellers
The main propulsion system of each vessel consists of one medium sized Schotel EcoPeller type SRE 210 (500kW) driven by an electric motor. This motor will be electrically powered by a batery bank with a 1,846kW/h capacity. With its special hydrodynamically optmised design, the SRE generates maximum steering forces, thereby enabling top performance in terms of overall efciency and course stability. This reduces fuel consumpton and ensures lower operatng costs and lower emissions. Moreover, the EcoPeller is the frst azimuth unit consistently developed for an electric drive source. Eliminatng the gearbox has multple advantages, such as maximum mechanical efciency and a reduced noise level.
PumpJets
An electrically powered PumpJet type SPJ 57 (200kW) will be fted at the bow to act both as thruster and take-home system. The extremely compact SPJ will improve manoeuvrability and enables space-saving installaton with minimal displacement losses. Since the Schotel PumpJet is installed fush with the vessel’s hull, this not only minimises the ship resistance, but the risk of damage is also reduced considerably. This makes the robust SPJ the perfect choice for operaton in extremely shallow waters.
Sixteen fully loaded EU trailers
The vessels will be fted with a bridge forward and initally they will be operated with a crew on board. Once established, the vessels will operate fully autonomously for ASKO with the ability to transport sixteen fully loaded standard EU trailers at a tme. These will be stowed on the open deck with a loading ramp at the stern. The operatng speed will be 10 knots and it is antcipated that this mode of trailer transport will replace over 3.2 million road kilometres per year, in turn saving around 5,000t of CO2 every year. The 67m long vessels have been designed by Naval Dynamics in Norway. They will be built under DNV GL Classifcaton and fagged in Norway. The contract includes optons for two other vessels. Both vessels are scheduled to enter operaton in January 2022.
