Abstract
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.
Claims21
A subsea flying lead comprising:
- a fluid line comprising a tubing, wherein, in use, an electric current is transmitted along the tubing;
- a flying plate, wherein the fluid line terminates in a fluid coupler on the flying plate;
- and
- an electrical connector in the flying plate, wherein an electrical conductor runs from the tubing to the electrical connector;
- wherein the fluid line comprises a non-conducting section between the fluid coupler of the flying plate and the point at which the electrical conductor is connected to the tubing of the fluid line, wherein in use, the electric current is transmitted along the tubing through the electrical conductor to the electrical connector.
2 more elements
An electricity transmission apparatus comprising:
- a subsea structure comprising a fluid line comprising a tubing, the fluid line terminating in a fluid coupler on a fixed plate, and
- a subsea flying lead comprising a flying plate and a fluid line comprising a tubing, the fluid line terminating in a fluid coupler of the flying plate,
- wherein, in use, the fluid coupler of the fixed plate is coupled to the fluid coupler on the flying plate;
- wherein the subsea flying lead comprises an electrical connector in the flying plate, and wherein an electrical conductor runs from the tubing to the electrical connector, and
- wherein the subsea structure comprises an electrical connector on the fixed plate and, in use, the electrical connector of the fixed plate is connected to the electrical connector of the flying plate.
2 more elements
A method of transmitting an electric current to a component of an underwater hydrocarbon extraction facility, the method comprising:
- providing a subsea flying lead containing at least one fluid line comprising a tubing, the tubing terminating in a fluid coupler in a flying plate;
- providing a subsea structure containing at least one fluid line comprising a tubing, the tubing terminating in a fluid coupler in a fixed plate;
- connecting the flying plate to the fixed plate, such that the fluid coupler of the flying plate is coupled to the fluid coupler of the fixed plate;
- transmitting an electric current along the tubing of the fluid line of the subsea flying lead;
- and
- transmitting, via an electrical conductor, the electric current from the tubing of one of the fluid lines to the component.
