A system for monitoring and/or controlling at least one device mounted on a tubing string of a well, the system comprising: a down-well cable for conveying a signal to and/or from at least one device mounted on a tubing string of a well; a temporary surface cable for conveying a signal between the at least one device and a first monitor/control station prior to and/or during installation of a tubing string in a well; a permanent surface cable for conveying a signal between the at least one device and a second monitor/control station after installation of the tubing string in a well; and switch means configurable between a first configuration, in which the down-well cable and the temporary cable are connected, and a second configuration, in which the down-well cable and the permanent cable are connected.

Sub sea control and monitoring system

An electrical penetrator connector has a fixed coupler pin unit which incorporates a pin having a conductive element. A reciprocatable component includes a housing defining a bore into which the pin may be inserted. Within the bore is a retractable shuttle pin. A chamber contains dielectric fluid. A flow path for the dielectric fluid is configured to move the fluid past a contact in the bore which is to touch the contact on the pin. The dielectric fluid circulates round the flow path every time the pin is inserted into the bore.
