Abstract

En undervannsgjenstand (1,2) beskyttes ved i nærheten av gjenstanden (1,2) å fastgjøre en kappe (4,5) av et fleksi- belt materiale, hvilken kappe (4,5) inneholder et elastomert materiale (10) som er i stand til å svelle ved påvirkning fra en væske overfor hvilken kappen (4,5) er effektivt ugjennomtrengelig, idet væsken ledes inn i kappen (4,5) for å forårsake svelling av det elastomere materiale (10) enten for eller etter at gjenstanden (1,2) er plassert inne i kap- pen (4,5). Gjenstanden kan være et ror (1,2) plassert inne i kappen (4,5), og en beskyttet undervannsrørledning kan om- fatte et antall ror (1,2) som er føyd sammen ende mot ende, idet hvert rør er plassert inne i en omsluttende langstrakt kappe (4,5) dannet av et fleksibelt materiale, hvor hver kappe ender i avstand fra hver ende av det respektive rør (1,2), og hvor hver ende av hver kappe (4,5) er festet til en endehette (7) som omslutter det respektive rør i omkrets- retningen, og hvor hver kappe (4,5) er fylt med væske for å danne en ettergivende konstruksjon som er i stand til å ab- sorbere utenfra påført støtenergi. Hvert blottlagt rørled- ningsparti mellom to tilgrensende kapper (4,5) kan skjermes ved hjelp av en beskyttende mantel (11) som kan ha lignende konstruksjon som kappene (4,5).An underwater article (1,2) is protected by attaching a sheath (4,5) of a flexible material in the vicinity of the object (1,2), which sheath (4,5) contains an elastomeric material (10) which is capable of swelling under the influence of a liquid over which the sheath (4,5) is effectively impermeable, the liquid being passed into the sheath (4,5) to cause swelling of the elastomeric material (10) either before or after the article (1,2) is located inside the cap (4,5). The article may be a rudder (1,2) located within the casing (4,5), and a protected subsea pipeline may comprise a plurality of rudders (1,2) joined together end-to-end, each pipe being placed inside in an enclosing elongated sheath (4,5) formed of a flexible material, each sheath terminating at a distance from each end of the respective tube (1,2), and each end of each sheath (4,5) being attached to an end cap (7) which encloses the respective tube in the circumferential direction and wherein each sheath (4,5) is filled with liquid to form a resilient structure capable of absorbing externally applied impact energy. Each exposed pipeline portion between two adjacent sheaths (4,5) can be shielded by means of a protective sheath (11) which may be similar in construction to the sheaths (4,5).
