Abstract
A system for fluid transfer is disclosed and includes a floatable buoy, an underwater hose, a plurality of underwater node units and circuitry. The underwater hose has a first end coupled to the floatable buoy and a second end. The plurality of underwater node units distributed along the length of the underwater hose and configured to generate positioning signals. The circuitry is configured to determine a relative distance between each of the plurality of undersea node units based on the generated positioning signals to generate a plurality of relative distances.

An underwater hose system for fluid transfer, the system comprising:
- a floatable buoy, and an underwater hose having a first end coupled to the floatable buoy and a second end;
- a plurality of underwater node units distributed along a length of the underwater hose and configured to generate positioning signals;
- and
- circuitry configured to determine a relative distance between each of the plurality of underwater node units based on the generated positioning signals to generate a plurality of relative distances.
An underwater hose system for fluid transfer, the system comprising:
- an underwater hose having a first end connected to a port at a surface and a second end connected to a pipeline end manifold (PLEM);
- a plurality of underwater node units distributed along a length of the underwater hose and configured to generate positioning signals;
- and
- circuitry configured to determine a relative distance between each of the plurality of underwater node units based on the generated positioning signals to generate a plurality of relative distances.
A method of operating an underwater hose for fluid transfer, the method comprising:
- generating a plurality of location signals by a plurality of underwater node units distributed along a length of the underwater hose;
- generating a plurality of relative distances based on the plurality of locations signals;
- determining a geometric shape and locations for the underwater hose;
- and
