Inductive couplers for subsea applications goes back many years but were generally replaced by mechanical connectors. In mooring systems, the issue is that we have two perpendicular axes of rotation and in order to determine the loads acting on the mooring line we need to cross both axes. Traditionally this is done using loose cables that move as rotation occurs around each axis. However, these looser cables are highly susceptible to damage, and the glands are not designed for motion. So, what happens is the conductors within the cable fatigues and fracture and seawater can enter the electronics area via the gland.
Flintstone has patented a dual inductive coupler set up where two pairs of inductive coupler modules are set perpendicular to each other allowing simultaneous rotation around two axes without the need for any loose cables as both power and signals can be transmitted across the gap.
