Waste water from ships• IMO has approved to designate the Baltic Sea as a special area under

Annex IV (sewage) of the MARPOL Convention.

Any discharge of sewage into the sea from a passenger ship will not be allowed unless the ship uses an approved sewage treatment plant capable of reducing nutrients (nitrogen and phosphorus) in addition to the current effluent standards.

Alternatively the passenger ship may discharge all sewage into port reception facilities.

• Application date for new passenger ships 1 January 2016, for old passenger ships 1 January 2018

• Conditional entry into force – adequate port reception facilities for sewage needed.

Baltic Sea - SECASOx Emission Control Area

In October 2008 the IMO set new quality requirements for maritime fuels. In practice the decision would mean replacing heavy fuel oil with diesel in Northern European waters in 2015.

The main requirement is that the sulphur content of maritime fuels be reduced in so-called Sulphur Emission Control Areas (SECAs), which include the Baltic Sea, North Sea and English Channel. In these regions the sulphur cap is currently 1.0%. This limit would be gradually lowered to just 0.1% by the start of 2015.

On the global level the reduction in the sulphur cap would be from the current 4.5% to 3.5% in the beginning of 2012, lowering further to 0.5% by 2020 or 2025.

Air Quality & Emissions

Reduction of emissions at Port of Turkucaused by new Viking Line vessel 2013:

NOx -13 %SO2 -17 %PM10 -19 %CO2 -5 %

LNG as alternative energy source for shipping:

NOx -90 %SO2 -100 %PM10 -100 %CO2 -20 %

Able to use three alternative fuels: traditionalheavy fuel oil, diesel or liquefied natural gas(LNG), which results in less emissions.

The hull of the vessel will be hydrodynamicallyoptimised to minimise its fuel consumption andcause the smallest possible swells, which isparticularly important when passing through anarchipelago.

New soundproofing technology - the noise levelwill be very low. In practice, new ship will be a veryquiet vessel, both when operating at sea and whilein port.
