Ecological Impacts: Biofouling Prevention and Management
Green Ship Technology Europe Conference
Copenhagen, March 21, 2019
The barnacle biofouling problem
Barnacles impact bottom line: higher fuel bills and maintenance costs
Barnacles impact marine ecology: transfer of IAS
Barnacles = bad news for fuel/emissions
Barnacles create added resistance on the hull = increased fuel consumption
and emissions.
~10% fuel saving (assuming 400USD/ton bunker fuel cost and industry 350bn tons per year use) equates to
savings of:
• ~35 million tonnes fuel
• USD 14bn
• >100 million tonnes of CO2 emissions
What about the IAS transfer risk?
Biofouling = bad news for marine ecosystem
“In New Zealand, biofouling was found to be responsible for about 70% of aquatic invasive
species, compared to just 3% from ballast water.” Cranfield et al. (1998). Adventive marine species in New
Zealand. NIWA Technical Report 34.
• Hulls are at risk from 1700 species, comprising over 4,000 organisms.
• IMO says any fouling is an IAS vector. (MEPC 1/Circ.792)
• Without adequate AF protection a vessel poses a great risk to IAS transfer.
A solution to the problem? I-Tech AB’s Selektope®
“That Swedish company with the tech that makes barnacles have a rave party to stop them attaching to a ship’s hull”
How does Selektope® work?

Think outside of the bucket, but still make sure you’re in it
A solution that also enables antifouling innovation

[G/L PAINT]Selektope® is efficacious at very low
concentrations (0.1% W/W)
The space gap allows paint makers to re-
engineer and optimise their AF coatings to
better protect vessels against the
complete spectra of fouling organisms
Powerful enough to replace copper but
flexible enough to boost copper-containing
