Abstract
A communication distribution unit, containing at least one power switch, said communication distribution unit comprising for an at least one consumer a power switch (4) based on a semiconductor design to switch on and off output lines (3) for the at least one consumer and the power switch (4) comprises at least one switching module (5).
Claims17
A system for subsea communication, comprising:
- a communication distribution unit (CDU) operatively connected with a plurality of subsea power consumers by a plurality of output lines, the CDU having a power switch comprising a plurality of switching modules, the power switch being coupled with the plurality of output lines to switch on and off communication with individual subsea power consumers by switching on and off communication to the corresponding output line of the plurality of output lines, wherein each switching module comprises a semiconductor switch, wherein each semiconductor switch comprises a metal-oxide-semiconductor field effect transistor (MOSFET) switch.
A system, comprising:
- a communication distribution unit (CDU) having at least one subsea power switch comprising at least one semiconductor switching module connected with at least one output line to communicate electrical power and data to at least one subsea power consumer;
- and further comprising an electric power unit (EPU) and a master control station (MCS) at a surface location and coupled with the CDU via communication cables routed subsea.
A method, comprising:
- providing a communication distribution unit (CDU) with a power switch having a plurality of semiconductor-based switching modules;
- deploying the CDU to a subsea location;
- coupling the power switch to a plurality of subsea power consumers via a plurality of communication lines;
- and
- switching power on and off with respect to the individual subsea power consumers of the plurality of subsea power consumers via automatic operation of individual semiconductor-based switching modules of the plurality of semiconductor-based switching modules, wherein switching comprises using the subsea power switch to switch both AC and DC currents.
