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.

Norsjór won Kristiansand Municipality’s award for sustainable business idea, and the same week the company walked away with Sparebanken Sør’s sustainability initiative award.

One early Monday morning, Amalie got to present our work and the technology to the listeners of Sørlandet on the radio and television.

International recognition

We are selected as one of the ten most prominent biofouling inflators in the world, hence World Ocean Council & The Ocean Opportunity Lab.

Top 3 in Nor-shipping young entrepreneur award

Norsjór made it all the way to top 3 in Nor-shipping young entrepreneur award 2022. We also had the opportunity to participate in the panel on green technology in shipping.

Almost always clean hull

The only technology in the world that can deliver close to always clean hulls. The graph shows fuel consumption over a five-year period and with Norsjór you will have a saving of up to 30%.

Adaptive to all surfaces

No surface or structure restrictions.

Effective and gentle

Leaves a smooth surface without damaging the anti-fouling.

Proactive treatment of biofouling

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

Scalable to other industries

Ecosystem and invasive 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 consumption and GHG emission

Biofouling will over time lead to corrosion. The most prominent impact on vessel hulls is the friction created, leading to increased fuel consumption, speed loss and GHG emissions.

The organisms that cling to the hull will increase fuel consumption by up to 23%.

In 2050 the emissions from shipping is required to be reduced by 50% and by cleaning the hull, CO2 emissions can be reduced by 25% – 55%.

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.
