LMG Marin have been awarded for the design of two battery-plug-in double ended ferries for the Festøya-Solvåg connection. The two vessels, with a capacity of 296 passengers and 120 personal cars will feature innovative solutions for environmentally friendly operation, with great focus on ensuring the lowest possible energy consumption. The vessels will be delivered in the Fourth Quarter of 2019. The LMG Marin’s scope of work for this project covers the complete Class documentation.
On 11th July 2018 Remontowa Shipbuilding signed a contract for the construction of two Double Ended Diesel Electric Hybrid ferries for Norled, based on the LMG Marin design LMG 120-DEH.
The new ferries will be equipped with an innovative and highly efficient Diesel Electric Hybrid system. In normal operation the entire 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 abt. 11 minutes. A fast charging solution of pantograph or plug-in type will therefore be used in order 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, e.g. in peak shaving mode.
The new ferries will service the Festøya-Solavågen connection, close to Ålesund in Norway. They will be 114,4m long, 17,7m wide and capable of taking on board up to 120 personal cars and 296 passengers. 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 LMG Marin who will also deliver the complete Class documentation. The design LMG 120-DEH features many energy efficient solutions including general use of heat recovery, full LED lighting, highly efficiency electric power transmission, demand-dependent HVAC system, low friction hull paint and lightweight construction.
The LMG 120-DEH design (with registered design protection) is also characterized by an innovative vehicle deck and accommodation arrangement that allows for fast and safe vehicle loading, significant energy savings and improved safety for crew and passengers.
