Abstract

A termination of a tension member (1), for use as a tendon or tether for a tension leg platform. The tension member (1) consists of a plurality of carbon fibre filaments gathered into one or more strands (2) in which the filaments run against one another. A sheath (3) is provided around the strands. Each strand (2) is terminated in a receiving member (6) and the receiving member (6) is suspended in a recess (12) in a suspension member (7). The strands (1) are, over an area, spread out from a bundled strand to an arrangement of the individual filaments lying apart from each other. This spread-out area is held together by a protective cone (10) which prevents the spreading out from travelling dawn the strand. The individual carbon fibre filaments (2) are inserted into respective cavities (4) in a receiving member (3) and secured therein with a solidifying substance (5). The cavities in the receiving body (3) may be through-going, or they nay be blind. Moreover, the cavities (4) may be of different configurations, from a hole of uniform diameter, an upward or downward facing conical cavity, or a gradually stepped cavity. By securing the carbon fibre filaments in this way, a good anchoring of each individual filament is ensured, as well as a longitudinal adjustment of the filaments, which gives a uniformly distributed load over the strand (1), and that in the main only axial forces are applied to the individual carbon fibre filaments (2).
