Norwegian Electric Systems has agreed to upgrade ferry Tõll’s diesel-electric propulsion system into an environmentally friendly battery-hybrid.
The company was selected as the system integrator on the hybridisation project after signing the contract with the Estonian shipbuilder Baltic Workboats.
In July, Tallinna Sadam subsidiary and ferry operator TS Laevad signed an agreement with the main contractor Baltic Workboats to rebuild ferry Tõll.
While Baltic Workboats is responsible for the construction works on the ferry, Corvus Energy will supply battery banks and LMG Marin will design a peak-shaving hybrid solution.
The project costs €1.6m and the reconstruction works will commence mid-October.
Following the completion of the hybridisation project, the ferry’s diesel fuel consumption will decrease by approximately one fifth.
According to the agreement, Tõll is required to start using battery power by 29 February 2020.
Norwegian Electric Systems regional sales manager Fridtjof Erichsen said: “We have been in close contact with TS Laevad, LMG Marin, Corvus Energy and Baltic Workboats during the sales process.”
The technology will be installed on TS Laevad’s all four new electric ferries.
The hybrid-electric propulsion system will include an energy storage system, a Norwegian electric switchboard and an electric transformer, as well as an energy management system.
Norwegian Electric Systems will also be involved in the project management engineering, calculations commissioning and a sea trial.
