WFS Technologies, a global company in the delivery of subsea wireless instrumentation and control solutions to the Offshore oil and gas and renewables industries, launched a subsea wireless power solution to complement its existing range of subsea wireless controllers, modems and dataloggers.
The WPT (Wireless Power Transfer) solution enables contactless recharging or powering of equipment in demanding offshore environments, avoiding wet mate/stab connections at depth and reducing electrical failure. The power can be delivered by ROV, so the equipment can be charged without being raised to the surface. The solution can also incorporate high-speed wireless data communications if required.
With power transfer capability between 10 W and 3 kW and power transfer efficiency up to 90%, at distances up to 30cm, WPT can deliver value in applications such as:
Subsea Sensors: WPT can be used to recharge “sealed for life” sensors reducing maintenance as no battery will ever need to be replaced
Autonomous Vehicles: WPT can extend deployment length by providing power in situ rather than surfacing a vehicle to connect and recharge
Subsea Equipment: WPT can provide an emergency power supply to a failed underwater system and due to elimination of cables can provide power to moving or rotating machinery such as a slip ring or subsea turbine
