“…3 d shows the experimental V‐type frequency splitting in air, freshwater and seawater together. The load voltages in three media have no significant differences [12–14, 16–19, 21, 22] and thus the circuit model in air is also useful to describe the WPT systems in freshwater and seawater and the frequency splitting analysis in air is also applicable in freshwater and seawater.…”

“…Furthermore, many other planar and coaxial systems that achieved power transfer values below 100 W or did not provide enough information to analyze their parameters can also be found in the literature [159,[200][201][202][203][204][205][206]. Additionally, some other works present comparisons between planar topologies [207] and planar and coaxial topologies [208].…”

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.

“…RF underwater communications finds applications in coastline protection and surveillance, off-shore oil and gas field monitoring, underwater environmental observation for exploration as well as oceanographic data collection [1], [2]. In these applications, communications requires downloading of mission data from the AUV to the docking station, successful docking of the AUV at the station for recharging through wireless power transfer [3], exchange of data between AUVs and underwater wireless sensor nodes. Critical Consideration of the three underwater technologies shows that despite the capability of acoustics and ultrasonic signals to be used for long range communications, the technology suffers from poor immunity to noise, low data-rates and high round-trip channel latency and thereby remain unfit for real-time and broadband underwater communications [2], [4], [5].…”

Transmission and reception of high-speed short range signal is important for successful underwater water communications between an Autonomous Underwater Vehicle (AUV) or Remote Operated Vehicles (ROVs) and a docking station or underwater sensor nodes during a survey mission. The need for this form of application is currently receiving global attention from scientific groups and industries. Hence, underwater antennas are therefore required to provide these links and achieve good data rates and propagation distances for these applications either in fresh or sea water scenario.In this paper, the performance of loop antenna placed at a specified distance and parallel to the ground plane is assessed through simulation for usage in fresh water and operating in the High Frequency (HF) band. Three variations of this antenna namely; the circular loop, the square loop and the delta loop antennas has been placed on two different ground plane shapes (circular and square) for analyses of their performances. These antennas were designed in FEKO, an electromagnetic simulation software and their performance is assessed in terms of bandwidth and directivity. The results obtained shows that the antennas exhibit wideband and high directivity with square loop antenna placed on a square ground plane having slight advantages over the other antennas with respect to their bandwidth and directivity. Experimental results added for the same antenna, confirmed its performance in terms of the measured parameters are in good agreement with simulation results.
