Remontowa scoops Norled hybrid ferry order
Norled has contracted Remontowa Shipbuilding to construct two diesel electric hybrid ferries

Remontowa Shipbuilding has signed a contract for the construction of two double-ended diesel electric hybrid ferries for Norled. 

The new ferries will be equipped with a diesel electric hybrid system. The shipyard explained that in normal operation the required power will be taken from two battery packs installed on board. The batteries will be recharged from the land grid during the vessels stay at quay, which will typically be about 11 minutes.

Remontowa added that a fast charging solution of pantograph or plug-in type will be used to ensure that the required state of charge of the batteries is maintained. The shore charging system will be integrated with an automatic mooring system (of vacuum or magnetic type) holding the ferries when at quay and giving the ‘green light’ for the charging process to start.

The intention is to use the generating sets that the vessels will be equipped with (running on 100% biodiesel), only in case of emergency. The electric system will be, however, prepared to operate them alongside batteries, for example in peak shaving mode.

The new ferries will service the Festøya-Solavågen connection. They will be capable of taking on board up to 120 cars and 296 passengers.

Remontowa said in a statement: “The equipment on board will be selected based on maximum efficiency criteria. A good example are the thrusters which will be pulling type units with integrated permanent magnet motors ensuring high efficiency even at very low loads.”

The ferries will be built according to the LMG 120-DEH design developed by naval architect LMG Marin, which will also deliver the complete class documentation. They will comply with the rules and regulations of DNV GL and Norwegian Maritime Administration and will be delivered in Q4 2019.

Norled’s fleet consists of 80 ferries, six of which been built at Remontowa Shipbuilding.
