Developing a Robust Wireless Power Transmission Solution for Challenging Marine Environments

The conventional wired charging arrangement utilized for ship-to-shore charging of underwater vehicles is susceptible to specific issues concerning unreliable connection mechanisms and safety concerns. This research article introduces an innovative approach involving system-level modeling and design of wireless power transmission for marine applications. The proposed configuration comprises three primary elements: (a) a mobile transmitter located on the shore (Shore-SMT), (b) a stationary receiver situated onboard, and (c) an additional mobile transmitter on the ship side (Ship-SMT). The concurrent rotation of the dual magnetic transmitters in proximity to the receiver coil conductor generates induced voltage, which is conducive to safe operation in a marine setting. The COMSOL® Multi-Physics environment is employed to model and simulate the proposed system utilizing the finite element method (FEM).
