MV Aasfjell is the first of two 9,300 dwt bulk carriers being built for Norway’s Aasen Shipping. It will also be the world’s largest self-discharger with an excavator. The Aasfjell and her sister ship, the Aasfoss, were ordered in June 2019 and are fitted with a hybrid propulsion system to cut emissions and run emission-free in port.
Each of the 394-foot vessels is fitted with a 339-kWh battery system to power all in-port operations and enable peak shaving on the main engine while at sea, setting a new standard in the maritime sector. The battery package will enable propulsion and maneuvering in port without the need of the main engine, in addition to its role at sea. According to Aasen, the battery pack will cut fuel use by 400 tons per year.
The vessels are powered by a Wartsila main engine that has been tuned to operate in the most ecologically friendly and efficient manner feasible. The primary engine has variable revolution capability, which allows it to save fuel consumption and emissions even further during slow steaming.
The hull has been designed for maximum efficiency as well. The propeller of the ship is also controlled by an active eco-control system. The battery package also benefits other aspects of the operation, such as an electric drive excavator that will operate quietly during loading and unloading activities, contributing to the vessel’s environmentally friendly operations.
