Claims (10)
1. Indretning til sænkning af lydniveauet af undersøiske lydkilder, med - et lydniveaureducerende omhyldningselement (2) med åbninger (4, 5) til afgivelse af en gasformigt stof, - en central opretningskomponent (1) for omhyldningselementet (2), - midler (3) til afstandsmæssig opretning af omhyldningselementet (2) langs den centrale opretningskomponent (1), kendetegnet ved, at - midlerne (3) til afstandsmæssig opretning af omhyldningselementet (2) omfatter ledelementer, som er indbyrdes forbundne på kædelignende måde og egnet til dannelse af en harmonikaagtigt strækbar føring for det lydniveaureducerende omhyldningselement (2).
2. Indretning ifølge krav 1, kendetegnet ved, at den centrale opretningskomponent (1) er en fortøjningspæl til offshoreinstallationer, der kan sænkes ned i havbunden.
3. Indretning ifølge krav 1 eller 2, kendetegnet ved, at det lydreducerende omhyldningselement (2) er et kunststofvæv.
4. Indretning ifølge et af krav 1 til 3, kendetegnet ved, at indretningen omfatter et lukket legeme dannet af omhyldningselementet (2) og i form af en symmetrisk cylindrisk ring omkring den centrale opretningskomponent (1).
5. Indretning ifølge krav 4, kendetegnet ved, at den cylindriske ring har åbninger (5) på indersiden for afgivelse af et gasformigt stof.
6. Indretning ifølge krav 4 eller 5, kendetegnet ved, at den cylindriske ring har åbninger (4) på ydersiden for afgivelse af et gasformigt stof.
7. Indretning ifølge et af krav 1 til 6, kendetegnet ved, at det gasformige stof er trykluft.
8. Indretning ifølge et af krav 1 til 7, kendetegnet ved, at indretningen omfatter en holdespindel orienteret skrueformet om den centrale opretningskomponent (1) langs dens længdeakse og dannet af ledelementerne, som er indbyrdes forbundne på kædeagtig måde.
9. Indretning ifølge krav 8, kendetegnet ved, at holdespindlens enkelte ledelementer er udformet, så de kan foldes mod hinanden og væk fra hinanden.
10. Indretning ifølge et af krav 1 til 9, kendetegnet ved, at ledelementerne har forspændte fjederelementer indenfor deres indbyrdes kædeagtige forbindelse.
