Latest Oceanography Technology Design and Developed by NIOT


Remotely operable oceanic surface vehicles are widely used for survey and monitoring of conditions at sea and measurement of oceanographic parameters. The main objective of this platform is used for remote rapid data collection at sea. This platform is capable of working in rough sea environments and climatic conditions with provision to mount oceanographic sensors. Low power and high endurance components are used for control and data acquisition. Sea Surface Robo-Boat is a mobile platform which gives us added advantage of improved range and data acquisition capabilities which helps us to validate the data collected from moored buoy systems after deployment. The control of the vehicle is done with the help of 4 channel 2.4GHz transmitter and receiver module. The Robo Boat can be equipped with a suite of sensors for measurement of ocean surface and upper ocean parameters.

Data Buoys are moored offshore platforms, fitted with meteorological and oceanographic sensors,deployed at specific locations to observe in-situ Met-Ocean data at regular intervals. The deep sea data buoys are floating platforms, which can be powered by solar cells charged battery pack and lithium battery (primary) pack. The buoy has a discus shaped hull and it can be split into two halves. A keel with counter weight is mounted under the hull to prevent capsizing of the buoy. Instrument container in the middle of buoy contains Electronic modules, power packages etc. The buoy is equipped with a mast to support the meteorological sensors and other devices like antennas, beacon light and radar reflectors etc. The buoy is anchored either with Inverse Catenary Type Mooring and have the capability to measure Ocean Current, Conductivity and Temperature up to 500 m depth and transmit hourly data through satellite. At the bottom, combination of Sinker and Anchor weight is connected with mooring line. The top segment if the mooring is made out of wire rope to protect the rope from fish bite. Then Nylon rope along with polypropylene rope is attached to give elasticity to the mooring and to keep the bottom mooring hardware not to touch the sea bed.

Data buoys play a primary role in providing in-situ ground-truth measurements, stands as a reference point for validating ocean related data from other observational means and provides inputs to various models to predict and forecast weather and long-term climatic changes. The coastal buoy systems are floating platform consisting of FRP hull, instrument container, sensor arms, frames, floats and other sensors selected based on the detailed study on coastal current, cyclone, water quality, radiation and other similar parameters. The mooring system is a combination of various types of ropes and chains connected by suitable mooring hardware. This keeps the buoy in the deployed location. In the case of coastal buoy, chain, combination rope .
