Sustainable Ship Management

Since the beginning of 1990, long before environment became a topic on the agenda among most ship owners we have worked systematically with reduce greenhouse gases emitted by shipping.

Leading the way towards truly sustainable shipping

When we talk sustainable shipping we mean just that. Environmental sustainability is as important to us as keeping our customers’ costs down without reducing service quality. What we know is that they go hand in hand.

Emissions

We put all our efforts regarding emission reductions into operating the vessels more fuel efficiently which will have a positive impact on all the emissions.

  • Among other things we have:
  • An online performance monitoring system which enables us to have full control of fuel performance for hull and propeller system
  • Strengthened routines for engine performance follow up
  • Implemented solution 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.

Optimal antifouling

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.

Managing refrigerants

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 accidently 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.
