Steady environmental work is part of Finnlines’ daily operations

Shipping has a huge overall environmental impact. The sector is governed by several laws and regulations. Complying with them is our priority, and we want Finnlines’ environmental work to meet the regulations in the sector without any compromises. Our goal is to develop our fleet and make it even more environmentally friendly. We also monitor the environmental impact of all our operations and services with an ISO 14001 standard-compliant environmental system.

Precise planning of routes and timetables is a practical way in which we reduce ship emissions. We also reduce emissions while sailing by optimising the speed, load and trim of the ship.

In the coming years, Finnlines will enhance its fleet with five new ships. Environmental requirements have played an important role in their design. These new ships will reduce the carbon footprint further. Three of them are ro-ro vessels with a hybrid system that uses green technology, and the other two are next-generation Superstar ro-pax vessels. The first ships in each series are expected to start operating between 2021 and 2023.

Combining cargo with passenger traffic for environmental efficiency

Marine traffic is about much more than transporting passengers. Up to 90% of the world’s commercial goods are transported by sea. According to the International Maritime Organization (IMO), it is the most environmentally friendly mode of transport. Shipping as more of transport only creates approximately 2.6% of the world’s greenhouse emissions, figures are similar to the emissions from global air traffic.

Shipping is extremely important to the industry and economy. Approximately 90% of Finnish exports and 80% of imports are transported by sea. Liner shipping service with frequent departures is especially crucial for processed products, such as foodstuffs.

Ships with a higher utilisation rate are also more environmentally efficient. The best results are achieved by combining passenger traffic with cargo transport. This is exactly what Finnlines’ ro-pax service does. The high utilisation rate of the routes and vessels makes sustainable and responsible travel possible.

Actions for reducing the emissions

Exhaust gas scrubbers

Finnlines has 20 ships, including combined cargo and passenger vessels, equipped with exhaust gas scrubbers that reduce emissions. The scrubbers remove harmful impurities from the ships’ exhaust gases. The company’s other vessels run on sulphur-free fuel oil.

Reducing ship's energy consumption

is an important part of Finnlines’ daily work for the environment. Ways to reduce consumption include efficient timetable planning and optimising the routes and speed.

Technological solutions to save energy

Technological solutions can also be used to reduce the ships’ energy consumption. Among other methods, savings have been achieved by reblading nine Finnlines ships and fitting six ships with bulb rudders that reduce water resistance. 

Ballast water treatment equipment

The purpose of ballast water is to stabilise the ship and achieve an optimal draught for travel. Sea water pumped in and out of tanks on the ship is usually used for the purpose, but the water may also introduce invasive alien species to new habitats. To prevent this, we have started to install new ballast water treatment equipment on our ships.

Cleaning the subsurface parts of the vessels

Micro-organisms, algae and vegetation may grow on the underwater parts of ships, increasing water resistance and therefore fuel consumption. The Finnlines’ ships operate in icy conditions, which means that anti-fouling agents cannot be used to prevent organisms or vegetation from becoming attached to the hull. Instead, the underwater parts of our ships’ hulls are cleaned 5–7 times a year.

Longer ships and more capacity

We lengthened six of our ro-ro vessels in 2018. This increased the capacity of each ship by 30% and made it possible to reduce the energy consumption of each transported unit.

Zero emissions in port

Finnlines' new ro-ro vessels that start operating in 2021–2023 will have lithium-ion batteries that are charged while at sea. The electricity collected while traveling is used in port. The hybrid vessels use traditional fuel at sea, but thanks to the batteries, they will not release any emissions in port.

Air lubrication system

The new hybrid vessels will have an air lubrication system that reduces fuel consumption. Located under the keel, it forms a layer of bubbles that reduces friction and water resistance.

Compare your trip's emissions

We compared the emissions of several modes of transport. Take a look what is the most environmentally friendly way to travel on the Baltic Sea?
