Our Services

Field of excellence

We offer consultancy services for marine environmental protection.

The expertise covers environmental impact of shipping, shipbuilding and repair, harbour pollution, monitoring of pollutants, but also knowledge transfer.

New legislations from the International Maritime Organisation (IMO) require new solutions and technologies on ships, but these often have an unknown impact on the marine environment.

Main areas are antifouling technologies, exhaust gas cleaning Systems for the recuction of SO2 emissions, greenhouse gas emissions and ballast water treatment.

In general we can help you to develop new products or technologies and make sure that you fulfill national and international legislations. Further we help to approve your products/technologies for your application. Finally, we make sure that the environmental impact is minimized and does not shift the environmental problem to another sector.

In detail this includes chemical analysis of pollutants or their reduction, investigation of by-products and environmental impact assessment.


Maritime Coatings and Paints:

In recent years Marena was involved in several projects related to the development of antifouling procedures, developments of material, study of environmental impacts and general product development.

Ballast water Treatment

The introduction of invasive marine species into new environments by ships’ ballast water, attached to ships’ hulls and via other vectors has been identified as one of the four greatest threats to the world’s oceans.

Air emissions

New IMO regulations require shipping to reduce their air emissions, especially in Emission Controlled Areas (ECAs).

Oil in water

There are many sources for mineral oil in the marine environment, but the biggest source is accidential oil spills.
