Actor: IHA-Lines Ltd   ●   Year: 2011   ●   Address: Meritullintori 6, Helsinki, Finland

© Iha-Lines OyIHA Lines Oy Helsinki Cruises built a new environmentally friendly cruiser for the archipelago cruise traffic in Helsinki region.


The new m/s Doris II cruiser was built in Finland during the years 2009-2011. In the environmentally friendly cruiser the future’s tightening environmental norms and regulations are taken into account. The cruiser uses a low emission diesel technique and engines that consume less fuel. A system which enables collecting of the greywater was added as a voluntary investment. The greywater consists of waste water of cooking and washing. Because of the new system, no waters are released into the Baltic Sea. Black and grey waters are treated on shore by city’s sewage treatment system.

Environmentally friendly cruiser offers the citizens and the companies organising the cruises a more environmentally friendly option. The City of Helsinki awarded the company with the Helsinki’s environment award of 2010 competition as a trendsetter. The positive publicity also promotes the development of the company.

Background information

Modern technology reducing the environmental impact was invested in the cruiser. According to the law it is permitted to release greywater straight into the sea. However, the system enabling the collection of greywaters in the new cruiser enables holding on to also these waters until connected to the city’s sewer system.

The cruiser is the first one in its class in Finland to meet the tightened EU requirements. It means investments to the structure and equipment that improve the maritime safety.
