The Swedish Maritime Administration is upgrading to energy-efficient LED lighting together with Finnish company Greenlux.
The Swedish Maritime Administration has five icebreakers, Ale, Atle, Frej, Oden, and Ymer. Work vessels Baltica and Scandica also have icebreaker capabilities.
As part of improving energy efficiency on vessels that produce their own electricity during the active icebreaking season, the Swedish Maritime Administration, together with Viking Supply Ships, made plans to change most of the lighting on board to presence-controlled energy-efficient LED lighting. Following the procurement, Greenlux won the contract.
First out for evaluation was the icebreaker YMER, where about 550 existing fluorescent luminaires were replaced with LED luminaires. Most of the luminaires have the wireless ActiveAhead control from Helvar Ltd for more significant energy savings as it learns how individuals move on board and turns on and off or dims down automatically.
“According to comprehensive tests, the conversion gives energy savings of 94% compared to the previous lighting. Also, the lighting experience onboard is improved,” says Magnus Byström, on-board technical manager.
