Abstract: A subsea umbilical comprising a plurality of longitudinal strength members, wherein at least one longitudinal strength member is a steel longitudinal strength member and has a semi-conductive coating. The invention can be used both in static, deepwater applications when substantial loading is to be applied to the umbilical, and in dynamic applications when the umbilical is too light and ballast is needed.

Abstract: 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. 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.
