Norwegian Electric Systems has signed a contract with the Estonian shipbuilder Baltic Workboats to deliver upgrade of the Diesel Electric Propulsion system onboard the ferry Tõll to battery-hybrid.

The ferry operator TS Laevad, a subsidiary of the listed port Company Tallinna Sadam, operates the ferry routes between Western Estonia’s major islands and mainland. The upgraded hybrid-ferry, serving the Virtsu-Kuivastu route, is expected to reduce the consumption of diesel fuel by one fifth as a result of the hybridisation project. The peak-shaving hybrid solution is designed by LMG Marin and the battery banks are supplied by Corvus Energy.

‘We have been in close contact with TS Laevad, LMG Marin, Corvus Energy and Baltic Workboats during the sales process’ said Fridtjof Erichsen, Regional Sales Manager in Norwegian Electric Systems.

Norwegian Electric Systems is the system integrator on the hybridisation project and has developed a very robust hybrid-electric propulsion system which is successfully delivered on several ferries, and comprises NES’ Quest energy storage system, switchboards, transformer, energy management and associated works and commissioning.

The conversion work will take place later this year and according to the agreement, Tõll will be sailing on battery power latest by February 2020. Based on a successful project, the technology will be deployed on all four new environmentally friendly electric ferries operated by TS Laevad.
