Smart Underwater Battery Power System for ROVs

Technology Overview

Ships coming into docks are required to undergo hull inspections and dock position checks. This task is traditionally performed by human divers. Recently, remotely operated underwater vehicles (ROVs) have been deployed to aid in this process. However, conventional ROVs require the use of long umbilical cables or tethers to power the vehicles from shore or from floating buoys. This causes significant power losses.The proposed technology relates to an onboard smart underwater battery power system for ROVs. It removes the need for tethering for ROVs, which increases the energy efficiency and overall portability of the vehicles.The technology owner is seeking partners to collaborate in various modes including technology licensing, consultancy project, research collaboration, etc.
