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 'Tőll' to battery-hybrid.

The ferry operator TS Laevad, a subsidiary of the 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, Norwegian Electric Systems.

Norwegian Electric will be system integrator for the project and has developed a robust hybrid-electric propulsion system which has been successfully delivered on several ferries, consisting of:

  • Quest
  • Energy Storage System
  • Norwegian Electric Switchboard
  • Norwegian Electric Transformer
  • Energy Management System
  • Project Management Engineering
  • Calculations Commissioning and sea trial

The conversion work will take place in Q4-2019, and according to the agreement, Tõll will be sailing on battery power latest by February 2020. Depending on the project's success, the technology will be deployed on four new environmentally friendly electric ferries operated by TS Laevad.
