Clean hull without exception

Advanced laser technology for biofouling removal

Norsjór is a Norwegian tech startup founded in early 2021. A diverse team of four are working on advanced pulsating fibre 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.

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

Clean hull without exception

The only technology in the world that can deliver clean hull without exceptions. The attachment of marine species has a significant impact on ship performance and efficiency because it increases the ship’s hydrodynamic volume, which increases the drag force and equates to up to 25% growth of fuel consumption and GHG emissions.

Norsjór are building an advanced subsea laser system to damage the biofouling organisme cells.

IMO explaining why you should worry about biofouling

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

Adaptive surface possibilities enabling scaling 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 25%.

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%.

Who can we assist?

Our technology 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.
