1. The system consists of power propeller, remote electronic communication device, black-and-white or color camera, camera pitch platform, user peripheral sensor interface, real-time online display unit, navigation and positioning device, automatic helmsman navigation unit, auxiliary lighting, Kevlar zero buoyancy towing cable and other unit components. Different types of ROV have different functions and are used to perform different tasks. They are widely used in military, coast guard, maritime affairs, customs, nuclear power, hydropower, offshore oil, fishery, maritime rescue, pipeline detection and marine scientific research.
Secondly, ROV is divided into observation level and operation level:
(1) The core components of observing ROV are underwater propeller and underwater camera system, sometimes supplemented by conventional sensors such as navigation and depth sensor. Small body size and weight, low load. The cost is lower.
(2) The operational ROV is used for underwater fishing, underwater construction and other applications, and it has a large volume and is equipped with underwater manipulator, hydraulic cutting machine and other working tools. High cost.
3. Offshore operation: ROV operators need to receive formal training. At present, major foreign ROV manufacturers provide personnel training and need to go abroad for training. Now China has trained some young operators, but it still mainly employs experienced foreign operators.
