Sustainable maintenance of maritime structures

Advanced laser technology

Norsjór uses a pulsating fiber-laser to remove corrosion, coating and fouling without harming the surface. The technology allows us to perform our services without any discharge of micro-plastics or biocides. Both the fouling waste and the chemical waste from the cleaning process are eliminated and collected, causing no damage to the ecosystem. The technology is easily adaptable and ready to be used for other surface treatments and areas.

Adaptive to all surfaces

No surface or structure restrictions.

Effective and gentle

Leaves a smooth surface without damaging the anti-fouling.

Gentle treatment of biofouling

Effective treatment of biofouling, leaving no harm to the ecosystem.

Scalable to other industries

Adaptive surface possibilities enabling scaling to other industries.

Ecosystem and alien species

The problem regarding alien species is highly recognized by the International Maritime Organization (IMO) who states that alien species are one of the biggest threats to the local ecosystems. In collaboration with IMO, NIMCO wants to establish an international standard, to ensure that the result from hull cleaning complies with clear rules and regulations. 

The standard will also ensure that the anti-fouling is not damaged during cleaning, and that the waste is collected in a practical and sustainable manner.

Fuel, Co2- and sulfur emissions

Fouling causes the ship hull to gain weight and fouling also creates more friction. Accumulation of fouling can cause turbulence, cavitation and noise which further affects the performance of sonars, speed logs and other hull-mounted instruments.

The organisms that cling to the hull will increase fuel consumption by up to 40%. In 2050 the CO2 emission from shipping is required to be reduced by 50% and by cleaning the hull, CO2 emissions can be reduced by 15% instantly by using our services. 

Who can we assist?

Our services have few limitations and we are always eager to learn about the challenges within your industry. The Norsjór team has special knowledge within the maritime industries related to inspection and antifouling. Typical areas would be shipping, dry-docks, shipping agents, public ports, charterers, antifouling manufacturers, aquaculture, subsurface, offshore wind and underwater structures in general.
