Ocean transportation is considered the most environmentally friendly means of transportation over long distances.
In Höegh Autoliners we strongly believe in taking responsibility for the environment in which we operate and taking measures to minimise our impact on the environment. Working with environmental issues is not only about finding excellent technical solutions, it is just as much about attitude and understanding. Höegh Wallem Ship Management which manages all Höegh Autoliners' own vessels is ISO 14001 certified and performs training, conferences and informal discussions on board and ashore. Even though we have come a long way, we are always investigating new possibilities for improving our environmental performance further
Emissions to air
Our main environmental challenge as a shipowning company is emissions to air. To meet this challenge, we are focusing our efforts on reducing our vessels' fuel consumption. In 2007, we launched the Energy Management Programme (eMAP), a fuel reduction project comprising of initiatives such as vessel performance, energy consumers, bunker purchasing and voyage planning and execution. The project focuses both on quick wins – small, low cost adjustments which have an immediate impact – as well as investing time and resources in more ambitious fuel savings programmes such as ships hull and machinery modifications.
Furthermore, a vessel elongation project, which increased vessel capacity from 6 400 to 7 800 car units, made the vessels up to 15 per cent more fuel efficient in terms of consumption per nautical mile per unit [MT/(Nm x CEU)]. From 2010 Höegh Autoliners’ overall fuel consumption per nautical mile per unit has been reduced by 12 per cent.
In 2015 and 2016, we took delivery of our New Horizon vessels which are some of the world’s largest PCTC vessels. With a focus on energy efficiency throughout the design process, the New Horizon will emit only half of the CO2 per transported unit, compared to a conventional car carrier.
We constantly work to minimise the amount of bilge water produced on board and uses only state of the art equipment on our vessels. We perform regular vetting inspections and training of our ship personnel to ensure that our strict bilge water policy is adhered to and well understood.
We continually work to minimise the amount of waste oil produced on board, by recovering fuel oil from waste oil and only using state of the art processing equipment on board our vessels.
We operate with a zero garbage overboard principle. All garbage produced on board is segregated and only disposed at approved shore facilities. Our vessels also apply onboard incineration. The only waste that is thrown overboard is biodegradable food waste as this is not harmful to the environment . This is only being done when the vessels are more than 12 nautical miles from shore.
Ballast water treatment
With a goal to be at the forefront in environmental protection at sea, minimising the spread of invasive species through ballast water is essential to Höegh Autoliners. Today we have Ballast Water Treatment (BWT) system implemented at our new vessels. Until we have a BWT system implemented on all vessels, Höegh Autoliners will continue to apply ballast water management, where we do ballast water exchange in approved areas.
Höegh Autoliners “donates” about 600 000 - 750 000 litres of fresh seawater from our ballast tanks each year to the Royal Artis Zoo in Amsterdam. The seawater is taken from the Bay of Biscay where it is delivered to the port of Amsterdam where it is tested for salinity, acidity and clarity. Once approved it is transported to Artis in special tankers and pumped in to the aquarium 150 000 litres at a time. The fresh seawater is distributed between the various saltwater systems of the Aquarium, providing comfortable habitats for an array of sea creatures.
Knowledge and Attitudes
All sea based personnel on Höegh Autoliners’ vessels go through an advanced environmental course. This way we ensure everyone is aware of Höegh’s strict environmental policies and can help in finding improvements in our day to day activities.
