Leading the way towards truly sustainable shipping
Since the beginning of 1990, before environment became a topic on the agenda among most ship owners, we have worked systematically to reduce greenhouse gases emitted by shipping. Today, we put all our efforts regarding this into operating the fleets we manage more fuel efficiently. This has a positive impact on emissions reductions.
Our work towards truly sustainable shipping never stops, we continuously work to keep improving all areas within our business.
Performance monitoring system
An online performance monitoring system enables us to have full control of fuel performance for hull and propeller systems. By monitoring performance we have managed to decrease fuel consumption with 40 000 tonnes over four years. We also have strengthened routines for engine performance follow up and implemented solutions for optimization of trim, draft and voyage planning.
Up-stream ballast water treatment
To eliminate the risk of transfer of invasive organisms between the world’s oceans, ballast water treatment are becoming standard in the shipping industry. We have long experience in operating and maintaining ballast water treatment systems (like USGC approved Pure Ballast) and limiting the footprint of the vessel operation.
Growth on the hull, commonly named fouling, contributes to poor energy performance, more emissions to air, as well as transfer of organisms between the oceans. We are constantly aiming to improve the antifouling solutions to find better and more environmentally adapted solutions that will also ensure optimal fuel efficiency.
In addition, we are following up in hull and propeller performance on daily basis for identify potential improvements and to ensure that our vessels operate as fuel efficient as possible and that potential transfer of organism are minimized.
Bilge water management
Long experience from operation of bilge water, management equipment ensuring that the equipment is in good working order at all times. Solutions for the onboard crew to ensure that we at all times comply with rules and regulation limiting the risk for the ship owner.
Reduce and manage waste
Operating a ship generates garbage similar to our everyday life. Today, sorting is a completely natural behavior onboard and part of the crews’ day-to-day work. Incinerators are used only as needed, in all instances our incinerators are maintained and operated optimally.
Sludge is generated from the fuel used onboard. Technical solutions such as sludge dewatering and flocculation units have been installed on many vessels. All Wallenius Marine managed vessel monitor and follow up sludge generation to ensure equipment is working optimally and to be able to provide feedback to operator with respect to fuel performance and sludge handling cost.
As ship managers we have focused on careful inspection regimes and follow up of our refrigerant plants in order to identify and mitigate release of cooling agents and limit cost for owner.
Stringent assessment of required chemicals
There is a need for a number of consumable items on a vessel that might have an environmental impact in use or if accidentally released. We assess all chemicals to be used onboard centrally and no chemicals can be used without approval. All users of chemicals are, through guidelines, appropriately informed of potential risks before using them.
Constant work to find environmentally sound alternatives and technologies that will not impact vessel performance is part of our every day job. As a result we have managed eliminate use of substances like rat poison and chlorine, moved to biodegradable wire greases, institutionalized mixing units to atomize and reduce use of chemicals, to mention a few.
Recycling of vessels
Wallenius Marine have worked with sustainable recycling of vessels over long time and have institutionalized processes and procedures for how to select recycling yards and how to manage the asset up to recycling. This enable us to further limit the environmental footprint over the lifetime of the asset and the optimal partner for ship owner. Based on recent recycling, the process ensures that 98 % of the materials is recycled
Future of zero emissions
Wallenius Marine strives for zero emissions and has a road map with actions to achieve this: ZERO (Zero Emission RoRo). The road map is focusing on energy consumption, energy carriers and emissions to the atmosphere, and shows that with today’s technology it is already possible to build completely emission free vessels.
