An apparatus and a method (1; 30; 50) for monitoring the laying of an underwater pipeline (7). The apparatus (1; 30; 50) comprises a body member (9, 11; 31) and a monitoring means (23, 27, 29; 33) connected to the body member (9, 11; 31) for monitoring the pipeline (7) as it is laid. A movement means (21) may be provided to assist movement of the body member (9, 11; 31) with respect to the pipeline (7). A means to position (10, 13) the body member (9, 11; 31) a distance from the pipeline dispenser (6; 47) is also provided, which may be in the form of a tether or a cable (10). A pipeline sealing device comprising a body member for insertion into a pipeline (7), where an explosive material is mounted on the body member. An apparatus and a method for deploying an elongate member (10; 13) within a conduit (7) where the apparatus comprises a body (51) which is coupled to the elongate member (10; 13). A positioning means maintains the body (51) substantially in a known position within the conduit (7). |
