“…Electromagnetic induction type CLPT has short transmission distance and high transmission efficiency, which is widely used in underwater electrical equipment, electric vehicles, biomedicine and robotics. Baer C M et al [7] developed a non-contact wet mateable connector based on CLPT, realizing 10W power transmission by coaxial nested coupling coils and signal rate of 600kbps by bidirectional optical communication. The scheme has broad prospect but its performances fail to meet the requirements of practical application.…”

At present, contact watertight connectors are commonly utilized for the connection between underwater electromechanical equipment and the seabed observation network. Such conventional watertight connectors are inevitably likely to be irreversibly worn when plugging and unplugging, besides complicated sealing structures and limited service life. This paper designs a Wet-Mateable connector aiming for Contactless Power Transfer and Optical Communication (PTOC-WMC), which is based on technology of Contactless Power Transmission (CLPT) and optical communication. Docking structure of the sockets and plugs are designed, facilitating Remotely Operated Vehicle (ROV) to operate. A prototype of the PTOC-WMC was established. The experimental results show that the connector designed can achieve 200W power transmission, with a maximum power transmission efficiency of 94%. The communication bandwidth reaches 18MHz. The PTOC-WMC can assist the rapid and safe deployment and operation of seabed observation network.

Underwater connectors are very essential and complex components of deep-sea engineering equipment and their design and manufacture have apparent multidisciplinary characteristics. Wet-mateable connectors (WMCs) represent the highest level of technology in this field, and only a very few countries in the world can produce WMCs. So, WMCs are likely to be a constraining factor to some maritime powers that might try to achieve breakthroughs in this field, constraining the innovation-driven development of deep-sea equipment. This paper gives a detailed overview of underwater connectors, both electrical and optical. First, the background of underwater connectors is introduced, and then the main available commercial off-the-shelf (COTS) products are described. Next, the new concept of functional units is proposed by the authors to help readers to have a better understanding of underwater connectors. Then, the basic theories of design are introduced according to different functional units, covering the aspects of electrical/optical connection, pressure-balanced oil-filled (PBOF) technology, penetrable self-sealing, aligning and locking structures. Finally, some discussions and conclusions are presented. This paper aims to reveal the secrets of key technologies used in underwater connectors, especially in WMCs.

“…The characteristics of the coupler, such as weight, coupling coefficient, and misalignment tolerance, significantly affect system performance in real-world applications. Granger developed two types of couplers for the AUV wireless power transmission (WPT) system [6,7]. One is a pair of coaxial spiral coils embedded in a stab connector, which requires precise alignment when the AUV stops at the docking station.…”

Spiral coaxial coils are widely used in wireless charging systems for autonomous underwater vehicles (AUVs). However, these coils can generate axial electromagnetic interference that may adversely affect the electronic components contained within the AUV. In order to overcome this issue, this paper introduced a pair of radially coupled coils which implement distributed ferrite cores. The mathematical model of the curly coils was derived, and its geometry parameters were optimized through the use of genetic algorithms. ANSYS Maxwell was used to analyze and optimize the layout of the ferrite cores. A prototype of the AUV wireless charging system was presented, demonstrating a maximum efficiency of 94% at 2.2 kW in salt water. The rotation adaptivity of the system was also tested, revealing stable output performance within the possible roll-angle variations of the AUV.
