Abstract

Et friksjonsreduserende skip l er utstyrt med en laminær utvidelse 5 på utsiden av skipets l skrog 3 med gasstråleutløp 4 beliggende i toppområdet 5 a av utvidelsen 3 for å drive gass inn i vannet til frembringelse av mikrobobler. Gass tilføres gasstråleutløpene 4 fra et gasstilforselsror 7 d som er plassert i nærheten for å forkorte banen så langt som praktisk mulig.
