Abstract: A fuel supply arrangement (1) for a fuel monitoring system (3). It comprises a fuel distribution arrangement (31) and a fuel monitoring outlet line (29) which, in use, is connected to a source of fuel (7). The fuel distribution arrangement (31) comprises a fuel monitoring supply line (57), to which is connected an inline fuel pump (53). A first fuel sensor supply circuit (67) and a second fuel sensor supply circuit (71) are each connected to the fuel monitoring supply circuit (57) downstream of the inline fuel pump (53). The first fuel sensor supply circuit (67) is provided with a sensor inlet connection and a sensor outlet connection for inline connection of a sensor. The second fuel sensor supply circuit (71) comprises a sensor manifold (91) with ports for connection of a plurality of sensors (97,99) in series with each other.

Abstract: A pressure protection system (32) has a docking manifold (44) to which an upstream portion (36) and a downstream portion (38) of a pipeline (34) are connected. Also connected to the docking manifold (44) is a retrievable module (64) which has a conduit circuit (66) that connects the upstream and downstream portions of the pipeline (34) enabling fluid to flow between the two portions (36, 38). The conduit circuit contains two fail-safe valves (72) which are controlled by a control module (80) within the retrievable module, and two pressure transmitters (76) co-operable with the control module (80). When wither pressure transmitter (76) senses fluid pressure in the conduit circuit (66) to be above a threshold value then it causes the control module (80) to effect closure of the valves (72) preventing the pressure rise from reaching the downstream portion (38) of the pipeline (34).
