Abstract

Skroget (2) til en flytende konstruksjon (1) har en gjennomgående sjakt ("moonpool") (3) med vertikal akse, i hvilken er montert en søyle (7) som er roterbar om aksen (10) til sjakten (3). Forankringskabler (8) er med sin øvre ende tilkoblet hvert sitt forbindelses- organ (17, 18). Hvert forbindelsesorgan omfatter et hode (17) beliggende i en utsparing (16) med radial retning i et omkretsparti av en horisontal skive (14) som danner det nedre partiet av søylen (7). Hodet (17) er^opphengt i søylen (7) via et strekkelement (18). Hodet (17), som er tilkoblet en forankringskabel (8), er bevegelig i radial retning i forhold til skiven (14) på søylen (7) og i forhold til en indre vegg i et lager (15) anordnet koaksialt i det nedre partiet av sjakten (3).The hull (2) of a floating structure (1) has a vertical shaft ("moonpool") (3) with a vertical axis, in which is mounted a column (7) rotatable about the axis (10) of the shaft (3). Anchoring cables (8) are connected at their upper ends to their respective connecting means (17, 18). Each connecting member comprises a head (17) located in a radial direction recess (16) in a circumferential portion of a horizontal disc (14) forming the lower portion of the column (7). The head (17) is suspended in the column (7) via a tension element (18). The head (17), which is connected to an anchor cable (8), is movable in a radial direction with respect to the disc (14) on the column (7) and relative to an inner wall in a bearing (15) arranged coaxially in the lower part of the shaft (3).
