摘要： A system for communicating electrical power and/or data signals along a pipe extending underwater, wherein the pipe comprises an inner, electrically-insulating sheath defining a conduit and an outer, electrically-insulating layer surrounding the inner sheath so as to define an annulus in-between. The system comprises an electric current generator located at a predetermined position on the pipe and operable to generate a current in the annulus; and a device positioned outside the outer layer of the pipe at a first location distant from the generator. The annulus is in electrical communication with the water at a second location on the pipe distant from the generator such that an electrical return path extends through the water between the second location and the position of generator; and the device is operable to draw power and/or data from the current generated in the annulus by the generator. A method of communicating electrical power and/or data signals along a pipe extending underwater comprises generating an electric current in the annulus at a predetermined position on the pipe; positioning a device outside the outer layer of the pipe at a first location distant from the generator; providing an electrical return path extending through the water from a second location distant from the generator where the annulus is in electrical communication with the water to the position of generator; and operating the device to draw power and/or data from the current generated in the annulus by the generator.

摘要： A subsea riser integrity diagnosis system comprising: one or more fibres deployed along a riser, preferably along the whole length subject to any potential failure, or alternatively deployed over the interval most subject to failure, a fibre optic sensor interrogation apparatus optically coupled to the fibre(s) and operable to detect changes in temperature (DTS), vibration (CRN), or strain (FBG) sensed by the fibre optic strain sensor, and a central processor means adapted to receive multiple measurement data from the interrogation apparatus and operable to determine from the received data the current status of temperature, pressure, vibration, strain or other parameters along the riser and to determine if the status is within safe limits or whether any number of potentially damaging events has occurred and to inform the operator(s) for possible action to be taken to safeguard the integrity of the riser.
