Unmanned underwater vehicles (UUVs) are key technologies to conduct preventive inspection and maintenance tasks in offshore renewable energy plants. Making such vehicles autonomous would lead to benefits such as improved availability, cost reduction and carbon emission minimization. However, some technological aspects, including the powering of these devices, remain with a long way to go. In this context, underwater wireless power transfer (UWPT) solutions have potential to overcome UUV powering drawbacks. Considering the relevance of this topic for offshore renewable plants, this work aims to provide a comprehensive summary of the state of the art regarding UPWT technologies. A technology intelligence study is conducted by means of a bibliographical survey. Regarding underwater wireless power transfer, the main methods are reviewed, and it is concluded that inductive wireless power transfer (IWPT) technologies have the most potential. These inductive systems are described, and their challenges in underwater environments are presented. A review of the underwater IWPT experiments and applications is conducted, and innovative solutions are listed. Achieving efficient and reliable UWPT technologies is not trivial, but significant progress is identified. Generally, the latest solutions exhibit efficiencies between 88% and 93% in laboratory settings, with power ratings reaching up to 1–3 kW. Based on the assessment, a power transfer within the range of 1 kW appears to be feasible and may be sufficient to operate small UUVs. However, work-class UUVs require at least a tenfold power increase. Thus, although UPWT has advanced significantly, further research is required to industrially establish these technologies.

AHLUWALIA, URVI. System for Wireless Charging of Battery-Powered Underwater Sensor Networks. (Under the direction of Dr. Zeljko Pantic).Wireless Power Transfer (WPT) systems have recently gained popularity in delivering energy underwater. Existing solutions that employ conductive charging by wet-mate connectors are costly, with complicated mating and maintenance requirements. WPT systems overcome these challenges by avoiding expensive material and complex mating mechanisms, thus making them viable alternatives.This thesis proposes an energy delivery system for wireless charging of battery-powered underwater sensor networks. Using ROVs and AUVs for periodic wireless recharging of deployed batteries, this system can increase the lifetime of such a sensor network. This thesis provides a background establishing the importance of recharging underwater sensor networks and the various challenges associated with this task. FEM-based procedures are used to design and optimize a wireless charging system and magnetic coupler, and system losses are calculated using an analytical model. The proposed system was evaluated using a prototype and provided experimental results for coils submerged in water at salinity levels similar to fresh and sea waters. These results were also compared with coils in air.The developed prototype, when operated at 50 W, worked at a maximum efficiency of 90% with coils submerged in seawater medium, with minimum possible gap, and an output voltage of 15.6 V. The experiments also show that the prototype can nominally deliver 50 W of power at 85% efficiency for a coil gap of 4 mm, 12.9 V output voltage in seawater salinity.Under similar conditions, the system has the worst-case efficiency of 77% when the coils are 12 mm apart.

One of the main challenges in the application of wireless power transmission systems is to achieve stable power transmission and constant transmission power under dynamically changing coupling conditions. A parity-time symmetric model for AUV (autonomous underwater robot) is proposed. Based on the coupling mode theory, the robustness of the parity-time symmetric wireless transmission system is investigated. The theoretical analysis shows that the AUV wireless power transmission system based on parity time symmetry can automatically obtain constant output power and constant transmission efficiency when the coupling coefficient is varied. Based on this theory, the experimental prototype was built by simulating the effects of relevant parameters using LTspice. And the experiments were conducted in air medium and seawater medium, respectively. The experimental results show that under the condition of parity time symmetry, the underwater wireless energy transmission voltage ratio is close to 1, and the transmission efficiency reaches 15%, in the range of 12.5 cm. The theoretical derivation has been verified.
