Beschreibung
Zusammenfassung:	This invention relates to a termination assembly for an umbilical comprising a chamber through which pass one or more tubes extending from the umbilical, the chamber containing a filler material, wherein at least one tube is provided with an anchor for securing the at least one tube in the filler material, the anchor comprising a shape memory material. The invention also relates to a method of making a termination assembly for an umbilical. The method comprises the steps of:(a) providing an anchor for mounting onto one of the tubes, the anchor comprising a shape memory material in a second phase and comprising an aperture which is in a second shape which the tube can pass through,(b)sliding the anchor onto the tube by passing the tube through the aperture, (c)allowing the shape memory alloy to undergo a phase change in which at least some of the second phase converts to a first phase such that the aperture returns towards a first shape which the tube cannot pass through, the anchor thereby gripping the tube, and (d) adding a filler material to the chamber.
