ABSTRACT According to the characteristics of the Subsea tree which is underwater, cooperating with the ROV robot, design a tool to realize the automatic underwater operation。 The tool has high torque output, light quality, and avoiding current shock。 Not only satisfy the requirement of vertical structure of the tree and the special requirements of horizontal Subsea tree, but also give attention to both sides, the unloading is convenient。 At the same time, the tool is equipped with non-contact sensor, can easily real-time detect reverse tool’s working condition, timely maintain。In addition, for the work of Marine environment, the use of hydraulic equipment to provide power supply,  will be safe and easy to be implemented。 With stainless steel along with anti-corrosion coating materials, the tool resists to sea water, maximizes reverse tool’s working life in ocean, so as to extend the underwater system life cycle。 In product design, use mature mechanical parts of the market as far as possible, to improve the quality of production at the same time, reduce the development cycle, easy to realize mass production。 For the main parts and component,With the method of analysis of optimization, strongly on the basis of meet the product function to reduce the consumption of materials, thus realizing the lightest weight, structure optimization。
