<p>The invention is concerned with ducting for mounting upon elongate members such as cables, tubes etc and particularly for such members which are deployed under water. A duct constructed in accordance with the invention has an internal service 14 defining an elongate internal chamber for receiving the elongate member. Means are provided, such as tension bands 21 , for applying tension around the duct to urge it toward the elongate member within. The duct is characterised by provision of internal spaces such as fins 30 which are interposed in use between the internal surface 14 of the duct and the external surface of the elongate member. The spaces are resiliently deformable and so are able to embrace elongate members having a range of different lateral dimensions.</p> |
