Design
MS Aksel Johan was built in 2024 and represents modern shipbuilding technology combined with sustainable solutions. The vessel was designed by Vestværftet, a well known shipyard recognized for innovative and efficient vessel designs. Vestværftet is located in Hvide Sande, Denmark, where MS Aksel Johan was recently delivered to the shipowner.
Engine and energy
MS Aksel Johan is equipped with a variable shaft generator that produces electrical power regardless of engine speed. The system utilizes heat from both exhaust gases and cooling water to generate electricity, resulting in significant fuel savings and improved energy efficiency. In addition, the vessel is fitted with a 600 kWh battery package, reducing the need for continuous generator operation and contributing to more sustainable and cost effective operations.
MS Aksel Johan is a combined Danish seine and crab fishing vessel, recognized for its innovative use of a thermoelectric power system. This system utilizes a large share of the exhaust heat, which is recovered and converted into electrical power on board. The vessel is also equipped with GreenOil filtration systems supplied by Ditech, ensuring clean oil and reduced maintenance costs. Together, these filtration solutions contribute to more sustainable and cost efficient operations and form an important part of the vessel’s environmentally focused profile.
