Reduce spread of aquatic species• Hull biofouling identified as key IAS vector.
Reduce fuel bill• Acknowledged fuel saving potential across the global fleet
corresponding to around 10-15 billion USD
Reduce exhaust emissions• >100 million tonnes of CO2 emissions saving + a lot of
SOx/NOx/PM
Regulatory disruption already executed• Remaining active agents are among the most thoroughly
evaluated industrial products all categories.
”The hull is in the air”

Alternatives to cut CO2 by 50%:
1) Technologies independent from ship type
and with relatively low investment
barrier. Your hull is a fundamental piece in
the CO2 equation!
2) Technologies suitable on specific vessels
and with high investment barriers
(alternative fuels, wind rotators, new bulb,
new propeller

Natural Receptor Stimulation
Octopamine Receptors from the Barnacle Balanus improvisus Are Activated by the α2-Adrenoceptor Agonist MedetomidineUlrika Lind, Magnus Alm Rosenblad, Linda Hasselberg Frank, Susanna Falkbring,

• Signal translates to
swimming/kicking behviour
1.Ligands, located outside the cell
2.Ligands connect to specific receptor proteins
3.The receptor releases a messenger once the
ligand has connected
• Medetomidine is highly selective and links to
the barnacles larvae octopamin receptor
transmitting signals.

is blocked.
• Kicking frequency is around
100/min
• Swim speed can be twice its
length per second.

Highly compatible with AF coating components
Combination with all existing biocides is
possible.

Selektope® - a differentiating agent
• Powerful enough to replace CuO and flexible enough to boost
• Repellent mode of action (flight mode)
• Used at around 0,1%w/w (a few grams per liter paint)
• Is ultra low leaching (e.g., 2g vs > 100g /day) .

Silicon epoxy coatings with Selektope®
• Purpose: Investigate if hard and slippery coatings doped with Selektope can be developed?
• Is there a demand link in to future trends on grooming, yachting (one-biocide only systems approved) etc?
• So far, epoxy-silicones prove strong barnacle resistance (but a lot of other fouling is attached)
• Next steps are to evaluate dynamic aspects etc.
Test panel location: west coast of Sweden. Static period: 18 months
