Diesel-electric propulsion for Estonia ferry conversion

Ferry operator TS Laevad, a subsidiary of 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 consume one fifth less diesel fuel after the hybridisation project. The peak-shaving hybrid solution was designed by LMG Marin and the battery banks 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 Norwegian Electric Systems regional sales manager Fridtjof Erichsen.

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 consists of:

• Quest energy storage system.
• Norwegian Electric switchboard.
• Norwegian Electric transformer.
• Energy management system.
• Project management.
• Engineering and calculations.
• Commissioning and sea trials.

The conversion work will take place in Q4 2019, and according to the agreement, Tõll will be sailing on battery power 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.

Riviera Maritime Media’s Maritime Hybrid & Electric Conference will examine how vessels can reduce fuel consumption, maintenance costs and emissions.
