AUV DESIGN and DEVELOPMENT FOR DEEP SEA MINING ( POLYMETALLIC NODULES) in MRC PUNE.pptx

This is about deep ocean mining project , a schematic view of this , how we could mining deep sea ocean with out harmming the deep ocean biological habitat , this is about AUV development for Deep Sea mining , for MRC pune stands for Marine research centre , pune . This is interhship project and stands most unique project among all IITs.

3. INTRODUCTION What is AUV ? An autonomous underwater vehicle, or AUV, is a self-propelled, unmanned, untethered underwater vehicle capable of carrying out simple activities with little or no human supervision. Function of AUV RESEARCH PURPOSE USING SONAR AND OTHER SENSORS USING FOR EXPLORATION AND MINING IN OCEAN MILITARY APPLICATION SUCH AS INTELLIGENCE AND SURVEILLANCE

4. WHY POLYMETALLIC NODULES? AVAILABILITY 21.1 Billion ton in CCZ area in pacific 380 million ton in central Indian Ocean. 20 Billion ton in PERU basin. Total amount - 500 billion ton. ENERGY RESOURCE Estimated 35 % - 45 % demand of metal will come from deep ocean. we can built 280 million of 75 kw electric vehicle battery. ENVIRONMENT IMPACT ECONOMICAL IMPACT It can reduce CO2 emission by 60 % pollution free wastage free Its under BLue Economy. It can finish the demand of metals. FORMATION FORMATION Polymetallic nodules primarily consist of precipitated iron oxyhydroxides and manganese oxides, onto which metals such as nickel, cobalt, copper, titanium and rare earth elements sorb. FORMATION

5. PROBLEM STATEMENT EXTRACTION The concept of polymetallic nodules as a serious commercial prospect emerged in the 1960's and 70's, leading to a rush to develop the technology to extract them. However, the industry never developed due to the cheap availability of nickel from more easily accessible land-based deposits. For current mining scenarios, the mining process is predicted to disturb about 120 km 2  of seabed per year per mining operation and represents a major environmental impact. However, owing to the presence of numerous volcanic hills with a relief of about 100m the extraction of nodules will be extremely patchy.

6. MY AUV DESIGN AND DEVELOPMENT SECONDARY AUV PRIMARY AUV EXPLORATION MINING Primary AUV - Torpedo design, have sensors and SONAR to know about the topography of seabed and find out where polymetallic nodules are stored. Secondary AUV - Non torpedo design , have buoyancy engine and storing fascilities to store nodules.

7. MY AUV DESIGN AND DEVELOPMENT Primary AUV is full of sensors and SONARs to imagine sea bed and use for mapping the structure of underwater world. Secondary AUV is designed for next operation just to take polymetallic nodules from seabed as much as possible without harming environments with the help of robotic arm. Secondary AUV can connect with primary AUV for two purpose 1) for travelling 2) For recharge purpose

11. RESULTS ANSYS SIMULATION OF PROPELLER

12. ULTIMATE AIM OF THIS PROJECT This design that collect the nodules is environment friendly and doesnt hurt any bilogical habitat compare to current technology of NIOT. Simple operation can be excuted by computer alogrithms and AI technology TIme efficient compare to other existing technology.

13. FURTHER PROGRESS 1.Estimate payload the secondary AUV because of store area. 2.Design the full electrical and computer architecture part of two AUVs. 3.Design of charging power station in primary AUV that charging secondary AUV. 4.Visualization the whole path of AUV with the help of path detection algorithm.
