MS Mjølner: first SHIFTR-vessel delivered to Norled
The first vessel designed for the SHIFTR battery swap system has been delivered to Norled.
The express catamaran vessel, designed and built by Oma Baatbyggeri, will service the 810 Trondheim-Vanvikan connection. The ferry is built with recycled aluminium, is 28.2m long and 9m wide.
Catering to 140 passengers, the vessel is equipped with the e-SEAMatic® BLUE solution from SEAM, which includes the e-SEAMatic® IAS and e-SEAMatic® EPMS system for optimal energy efficiency, and it designed to utilize the innovative SHIFTR battery swap system.
MS Mjølner is the first of four express ferries that will service the connections in the Trondheim Fjord. Together, they will cut emissions by at least 50%, compared to the current express vessels operating in this area.
For a short while, the ferry will run on diesel-electric propulsion, until the SHIFTR solution is fully installed.
The SHIFTR solution is an autonomous battery-swap charging robot, with a battery carousel installed on the vessel, and a robotic arm with a charging cabinet installed on shore. When docked, the robot will swap out the empty batteries with fully charged ones. The batteries are then recharged at a steady pace, without putting too much stress on the available power grid.
Norled, Aarbakke AS and SEAM have, in close collaboration, developed this solution for inland waterways that require high-speed, lightweight vessels and that may have limited power grid capacity.
For this vessel, SEAM has delivered the following:
e-SEAMatic® BLUE solution:
- e-SEAMatic® IAS
- e-SEAMatic® EPMS
- e-SEA® Drives
- Battery system
- e-SEA® Transformers
- e- SEA® Switchboards
- e-SEA® Motors
- Procos (propulsion control system)
