Abstract

Et system omfattende en undersjøisk konstruksjon som avgrenser et indre av systemet, hvor konstruksjonen er utsatt for en vannstrøm; en kappe på utsiden av den undersjøiske konstruksjon som dekker i det minste en del av en utvendig overflate av den undersjøiske konstruksjon, hvor kappen er valgt fra isolasjon og oppdriftsmoduler; hvor minst en ytterligere ledning er på utsiden av kappen; hvor en krage på utsiden av kappen er tilpasset for å opprettholde den i det minste ene ledning nærliggende kappen; og en innretning for undertrykking av virvelindusert vibrasjon på utsiden av den minst ene ledning, kragen, og kappen.A system comprising an undersea structure defining an interior of the system, wherein said structure is subjected to a stream of water; an outer shell of the subsea structure covering at least a portion of an outer surface of the subsea structure, the jacket being selected from insulation and buoyancy modules; where at least one additional wire is on the outside of the jacket; wherein a collar on the outside of the jacket is adapted to maintain the at least one wire adjacent the jacket; and a device for suppressing vortex-induced vibration on the outside of the at least one wire, the collar, and the sheath.
