Selek­tope® has fin­ished off the year the same way it started, by win­ning one of the industry’s most sought after envi­ron­men­tal acco­lades. “This has been a break­through year for Selek­tope, fol­low­ing the many years spent in research­ing, cer­ti­fy­ing, com­mer­cial­iz­ing and indus­tri­al­iz­ing the prod­uct,” says Philip Chaa­bane, CEO at I-Tech.

Selek­tope intro­duces for the first time ever a phar­ma­co­log­i­cal mode of action to com­bat bar­na­cle set­tle­ment. By tem­porar­ily stim­u­lat­ing the octopamine recep­tor in the bar­na­cle lar­vae, caus­ing their legs to start kick­ing, the organ­isms are repelled from the hull. These ground­break­ing dis­cov­er­ies enable unri­valled power at minute con­cen­tra­tions, yet within the lim­its of the most rig­or­ous risk assess­ment bod­ies in the indus­try. Selek­tope is an organic, non-metal com­pound with effi­cacy proven at 0.1% w/w.


The ship­ping indus­try spends over USD 200 bil­lion on fuel each year, rep­re­sent­ing the lion part of oper­a­tional costs for the ship­ping com­mu­nity. Enhanced reg­u­la­tion on emis­sions to air will fur­ther increase fuel costs, as higher fuel grades will be required.
Selek­tope is an approved selec­tive antifoul­ing agent that pro­tects ship hulls from bar­na­cles and the drag they cause, which can lead to sig­nif­i­cant fuel sav­ings of more than 10 per­cent.

Selek­tope deliv­ers power at only a few grams per liter paint, leav­ing room for inno­va­tion at a paint maker level and opti­miz­ing hull per­for­mance while sharply reduc­ing bio­cide load­ings.



  • Improves sta­tic per­for­mance across the range of antifoul­ing tech­nolo­gies
  • Com­pli­ant with reg­u­la­tory author­i­ties for com­mer­cial ves­sels and leisure boats
  • Enables reduced bio­cide load­ings
  • Improved for­mu­la­tion flex­i­bil­ity
  • Pow­er­ful enough to replace cop­per, flex­i­ble enough to boost Cu-based for­mu­la­tions



  • Reduced foul­ing and improved fuel sav­ing
  • Extended sta­tic per­for­mance
  • Reduced need for hard scrub­bing through excel­lent per­for­mance against bar­na­cle induced foul­ing
  • Reduced risk of trans­port­ing inva­sive aquatic species
  • Improved envi­ron­men­tal pro­file by reduc­ing bio­cide load­ings in antifoul­ing for­mu­la­tions


The hull of a ves­sel can become heav­ily fouled with both macro and micro foul­ing, caus­ing sig­nif­i­cantly increased fuel con­sump­tion when mov­ing. Tests show that using pow­er­ful Selek­tope con­tain­ing antifoul­ing pro­ducts greatly reduces foul­ing, poten­tially sav­ing 30–40% on fuel costs, while own­ers oper­at­ing in aggres­sive waters and with an unpre­dictable idling scheme can avoid fuel penal­ties of more than USD 100,000/year for small ves­sels and over USD 1M/year for large ves­sels.

Com­par­a­tive results after 7 months in sta­tic con­di­tions on the west coast of Swe­den.







Biofouling | Impact | Invasive Species | Fouling Pressure


The vari­ety among bio­foul­ing organ­isms is highly diverse and extends far beyond attach­ment of bar­na­cles and sea­weeds. Accord­ing to some esti­mates, over 1,700 species com­pris­ing over 4,000 organ­isms are respon­si­ble for bio­foul­ing which occurs in all oceans around the globe. Bio­foul­ing is divided into micro foul­ing — biofilm for­ma­tion and bac­te­r­ial adhe­sion, and macro foul­ing — attach­ment of larger organ­isms.


Bio­foul­ing has a large impact on fuel con­sump­tion as it has been demon­strated that bar­na­cle foul­ing increase fric­tional drag by up to 80%. Despite major con­tin­ued devel­op­ment of more effi­cient coat­ing sys­tems there is still room for improve­ment to cut another 10% of the indus­tries total fuel con­sump­tion amount­ing to some 350 mil­lion tons of fuel per year. Selek­tope is brought to mar­ket to main­tain smooth, clean hulls achiev­ing energy effi­ciency and reduc­ing oper­a­tional and envi­ron­men­tal costs.


Fouled hulls are fur­ther known to act as vehi­cles of trans­porta­tion for inva­sive aquatic species, which have proven to have neg­a­tive effects on marine eco-sys­tems. The issue is being adressed region­ally and through IMO, result­ing in pos­si­ble hull inspec­tions prior to mak­ing port calls.


Although marine bio­foul­ing occurs in all oceans, the foul­ing risk is dif­fer­ent in dif­fer­ent areas. In gen­eral, trop­i­cal or sub-trop­i­cal waters are con­sid­ered high risk areas with rapid growth and set­tle­ment of organ­isms. With aver­age global water tem­per­a­tures increas­ing, high risk foul­ing is expand­ing, cov­er­ing larger areas. Idling in these regions is there­fore asso­ci­ated with large penal­ties as regards fuel con­sump­tion and main­te­nance costs.

Lena Lindblad

I-Tech co-founder and R&D Direc­tor Lena Lind­blad spoke at the Swedish Shipown­ers’ Association’s Entre­pre­neur Day about how the intro­duc­tion of a phar­ma­co­log­i­cal mode of action to com­bat bar­na­cle set­tle­ment has proven to be both eco­nom­i­cally and envi­ron­men­tally effec­tive in fight­ing antifoul­ing.


Laurin Maritime

Mikael Karls­son talks about why Lau­rin Mar­itime, after try­ing the Selek­tope test pan­els, is the first ship­ping com­pany to do a full hull paint­ing with Selek­tope as the active antifoul­ing agent. 



Fredrik Stub­ner, Mar­in­vest, talks about the impor­tance of keep­ing the hulls on the company’s ves­sels clean, and how Selek­tope test pan­els have shown promis­ing results.

Sav­ing lives with­out any gov­ern­ment fund­ing. In case of alarm, the Swedish Sea Res­cue Soci­etys vol­un­teers are set to depart within 15 min­utes, at any time, in any weather — 24 hours a day. Watch the film to find out how Selek­tope helps them save money, but more impor­tantly time, every day.

I-Tech is a Gothen­burg based com­pany with global reach, hold­ing all IP and reg­u­la­tory rights to its all new antifoul­ing agent Selek­tope (generic name, Medeto­mi­dine). Rely­ing on aca­d­e­mic research in Gothen­burg, I-Tech has since 2006 suc­cess­fully trans­formed the sci­en­tific inven­tion into a com­mer­cially ready and avail­able antifoul­ing agent. I-Tech has had sev­eral list­ings as top start-up com­pany and is now an entirely com­mer­cially dri­ven com­pany with con­tin­u­ous rev­enue streams.

I-Tech’s busi­ness con­cept is to offer Selek­tope to the global paint indus­try as the prin­ci­pal active agent in marine antifoul­ing paints. The com­pany is highly com­mit­ted to serv­ing its cus­tomers in the best way pos­si­ble, and is always ready to sup­port its cus­tomers, from reg­u­la­tor sup­port and advice to indus­trial inte­gra­tion and han­dling of Selek­tope. The com­pany will also con­tin­u­ously seek and defend the nec­es­sary patents in order to use Selek­tope as a sub­stance against marine bio­foul­ing on a global basis.


The company’s vision is to become the pre­ferred sup­plier to the pro­fes­sional and non-pro­fes­sional antifoul­ing mar­ket. The company’s mis­sion is to bring new dimen­sions to the global antifoul­ing indus­try.
