Abstract

A measurement apparatus is disclosed for connection to an end of a cable (1) having at least one of: at least one electrically conductive core (11) for carrying electrical current and/or electrical signals along the cable; at least one electromagnetic waveguide (12) for carrying electromagnetic signals along the cable; and at least one bore (13) for conveying a fluid along the cable. The measurement apparatus comprises: connection means (4) for connecting to the end in an above-water or out-of-water environment to make at least one of: at least one respective electrical connection (41) to at least one core, at least one respective waveguide connection (42) to at least one waveguide for sending an electromagnetic signal along the waveguide, and at least one respective fluid or hydraulic connection (43) to at least one bore; and measuring means (5) connected to the connection means and operable to perform at least one measurement, via the connection means, on a connected cable. The measurement apparatus is deployable, when connected to an end of the cable, with the cable end to an underwater location for a period of time, and recoverable with the connected cable end after the period of time to an above-water or out-of-water location. The measuring means is operable to perform the measurement(s) while the measurement apparatus is connected to the cable end and at least while submerged with the connected cable end and/or after recovery with the connected cable end from the underwater location to the above-water or out-of-water location.
