Abstract

Det er beskrevet et kompresjonselement (10) med et bøyelig elastisk legeme (12). Kompresjonselementet (10) utviser en avtagende aksiell fJæringsgrad l respons til aksiell bevegelse og kompresjon av det bøyelige legemet. Kompresjonselementet kan brukes alene eller l kombinasjon med andre kompresjonselemen- ter i stigerørsstrekksystemer for å opprettholde en l det vesentlige konstant oppoverrettet strekkraft på et stigerør (18) når det beveges aksielt l forhold til en flytende plattform (20).
