Claim 2:
3. A method of coupling a controller of a liquid hydrogen offload system to a liquid hydrogen tanker and detecting hydrogen gas leakage at a coupling to the liquid hydrogen tanker, comprising:
providing a control conduit comprising:
an air control line, wherein the air control line is configured to transmit a control signal from the controller to the liquid hydrogen tanker;
a gas detector, wherein the gas detector is configured to detect hydrogen gas leakage at a coupling to the liquid hydrogen tanker and to provide a gas detector signal to the controller to indicate detection of a hydrogen leak;
a connector, wherein the connector is configured to secure the gas detector to the air control line, wherein the connector comprises one or more of a fastener, a shroud, a housing, or a tubing; and
a coupler at one end of the control conduit, wherein the gas detector is secured to the air control line at a predetermined distance selected from a group consisting of: less than 5 cm, less than 10 cm, less than 15 cm, less than 20 cm, less than 25 cm, less than 50 cm, less than 100 cm, less than 150 cm, and less than 200 cm from the coupler; and

coupling the control conduit to a liquid hydrogen tanker.
