Abstract

Et system som omfatter en undervannskonstruksjon som avgrenser et indre i systemet. Undervannskonstruksjonen er utsatt for en vannstrøm. Minst én line strekker seg uten på konstruksjonen. En krage utenpå konstruksjonen er innrettet for å holde den minst ene line nær denne, og en anordning er anordnet utenpå linen(e) og kragen.
