Estonia’s border authorities have launched a hybrid patrol vessel that helps protect the environment from oil spills and cuts fuel consumption using innovative Danfoss Editron hybrid electric propulsion.

The 45-metre ship built by Baltic Workboats is equipped with Editron hybrid electric drivetrain systems, allowing efficient and quiet electric cruising and a swift, powerful reaction to emergencies.

“The needs of the patrol boat made it an excellent project to build as a hybrid vessel,” said Peeter Raamat, Head of Technical Department at Baltic Workboats.

“For example, the hybrid electric benefit of engine redundancy is important for the Estonian Coast Guard — in case of engine failure, you can switch to diesel-electric or batteries — while you also have improved fuel efficiency and much lower noise levels in diesel-electric and fully-electric modes when compared to big diesel engines, which is a big benefit for the crew.”

Combating pollution

The wave-piercing patrol ship will be used by the Estonian Police and Border Guard Service, mainly for use in combatting pollution threats.

It is the largest patrol vessel ever built by Estonia based Baltic Workboats and the first in the firm’s emerging range of battery hybrid patrol ships.

The vessel contains an Editron marine system, which is half the size of a conventional diesel-electric propulsion and power plant system. Danfoss’s Permanent Magnet Machines reduce fuel and running costs, significantly reducing both payback period and CO2 emissions.
