| 7. A method of degaussing a water vessel having three vessel planes, the method comprising:
providing a plurality of degaussing coil loops running throughout a hull of the water vessel, with a plurality of said plurality
of degaussing coil loops arranged substantially parallel to each of said three perpendicular vessel planes, wherein each degaussing
coil loop comprises a light-weight reduced-size cable assembly, the cable assembly comprising:
a hollow support tube;
a high temperature superconductor cable wrapped around the hollow support tube, the support tube supporting the high temperature
superconductor cable;
a cryogenic tube with an elongated opening, wherein the high temperature cable and the hollow support tube are located within
the elongated opening of the cryogenic tube;
the method further comprising:
cooling a single-phase gaseous cryogen that is circulated in each degaussing coil loop;
circulating electrical currents through each of said plurality of degaussing coil loops; and
circulating in each degaussing coil loop, a single-phase gaseous cryogen through an inner core of each hollow support tube
to cool each high temperature superconductor cable.
