Sustainable biofouling removal

Advanced laser technology

Norsjór is a Norwegian tech startup, founded in early 2021. A diverse team of five are working on advance pulsating fiber laser technology to perform sustainable biofouling removal of maritime surfaces.

We aim to reduce corrosion, fuel consumption and greenhouse gas emission by removing biofouling without harming the ecosystem.

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.
