A safety node for a hydrocarbon extraction facility control system, the node comprising: a hydraulic input; a hydraulic output; a directional control valve disposed between the hydraulic input and the hydraulic output; and a functional safety electronics module containing a logic solver in operable communication with the directional control valve; wherein the logic solver is configured to operate the directional control valve to permit hydraulic communication between the hydraulic input and the hydraulic output in response to the presence of a given condition and inhibit hydraulic communication between the hydraulic input and the hydraulic output in response to the absence of a given condition.

Subsea safety node

A subsea flying lead containing a fluid line including a tubing, wherein, in use, an electric current is transmitted along the tubing. Such a flying lead may be used in an apparatus and method for transmitting electricity to a component of an underwater hydrocarbon extraction facility.

Subsea flying lead

An underwater hydrocarbon extraction facility including a plurality of actuators wherein each of the actuator includes: an electric motor arranged to operate the actuator; communication means configured to receive communication signals; and a controller connected to the communication means and the electric motor, said controller being operable to activate the electric motor in response to a received communication signal.

Underwater hydrocarbon extraction facility

A method of supplying multiple chemicals in a supply line. The method includes: supplying a first chemical to the supply line; and supplying a second chemical, different from the first chemical, to the supply line. The first and second chemicals are sequentially supplied as discrete slugs.

Multiple chemical supply line

An electronics module for a well installation configured to receive software via a wireless connection and methods of installing software on an electronics module for a well installation, are provided. An example of such electronics module comprises a short-range wireless receiver for wirelessly receiving software and/or data from an external wireless source. Modem external interface wiring can be employed as an antenna for the wireless receiver to receive the wireless transmission of the software and/or data.
