Matsya-6000 Successfully Tested

The Matsya-6000 is a groundbreaking deep-ocean human scientific submersible developed under India’s Deep Ocean Mission. It is designed to explore oceanic depths and enhance scientific research capabilities. The project is spearheaded by the Ministry of Earth Sciences and executed by the National Institute of Ocean Technology. The submersible can accommodate three individuals and is built with state-of-the-art technology.

Design and Features

Matsya-6000 features a 2.1-meter diameter spherical hull. Its design prioritises safety and functionality. The submersible is equipped with a main ballast system for diving and thrusters for multidirectional movement. A robust battery bank supplies power. Syntactic foam ensures buoyancy. The integration of advanced control hardware and software facilitates precise navigation.

Communication and Navigation Systems

The submersible includes a sophisticated communication setup. An acoustic modem, underwater telephone, and VHF ensure reliable communication. Underwater acoustic positioning and GPS are used for tracking. This comprehensive system enhances operational efficiency and safety during deep-sea missions.

Life Support and Human Integration

Inside the hull, human life-support systems are meticulously integrated. Displays monitor environmental and critical parameters. Navigation joysticks allow for easy manoeuvrability. The submersible is equipped with oceanographic sensors, underwater lighting, and external cameras. All systems are designed to support crew safety and operational success.

Testing and Development Phases

The development of Matsya-6000 involved extensive testing. Integrated dry tests were conducted over a 500-meter operational range. These tests assessed the functionality of power and control networks, flotation stability, and human support systems. The submersible was then transported to L&T Shipbuilding for wet tests.

Wet Testing and Performance Evaluation

The wet testing phase included eight dives – five unmanned and three manned. Each manned dive was rigorously qualified to ensure life support reliability. The tests evaluated the submersible’s performance in various parameters, including manoeuvrability and communication capabilities. However, challenges in underwater communication at shallow depths were noted.

Future Prospects

Successful wet tests have increased confidence in the Matsya-6000’s capabilities. Plans are in place for further testing at greater depths. By the end of 2025, shallow-water demonstrations at depths of up to 500 meters are expected. The project aims to solidify India’s position in ocean exploration and research.
