Remotely Operated Vehicles ROVs – A Technological Marvel!

5 Feb 2019 | Posted By

These unoccupied, highly manoeuvrable underwater robots/ underwater drones are operated by a pilot at the water surface that can access hard-to-reach areas or be used in hazardous conditions to inspect and assess submerged structures. ROVs come in a range of sizes, from that of a small computer to a small truck. The larger ones are rather heavy and require additional equipment such as a crane or a davit to put them over the side of a ship and into the water.

In such a short time since their implementation in the real world, ROV’s have already proven themselves to be extremely valuable in ocean exploration. So much so, they are also used for educational programs too! This raving success does raise the question of what’s better... The old tried and…...

Underwater inspection with the Bots

According to Ministry of Shipping, 95% of India’s trading by volume and 70% by value is done through maritime transport. This is facilitated by 200+ ports spread across 7500 kms of Indian coastline. Various other sectors like shipping (including ship building, ship repair and maintenance, ship recycling) and Oil and Gas are key drivers for this thriving maritime industry. One way scientists are trying to improve their understanding of underwater environment is through underwater vehicles which are programmable robotic devices that can independently study the ocean and its inhabitants. Deep sea exploration covers inspection of physical, chemical and biological conditions of the sea bed for scientific or commercial purpose. The effects of major 2010 Deepwater Horizon oil spill in Mexico, following the explosion and spilling of the Oil rig, has created awareness around underwater inspections and services of submerged structures in Oil & Gas industry. The traditional methods used to carry out inspections was done manually performed by trained and certified divers. Underwater diving is the process of going underwater with breathing apparatus and atmospheric diving suits that reduce the…...

Underwater inspection with the Bots-2

12 Jul 2016 | Posted By Planys Technologies

As you would have read in our first article, Remotely operated vehicles have been designed to meet the extreme demands of underwater with inspection of subsea structures in hazardous environments. Recap: As technologies and capabilities have increased, industries like Maritime (Ports and shipping) , Infrastructures (Dams and bridges) and Energy (Oil & Gas, Nuclear, Power and Desalination) have come to rely on ROVs (know more about what a ROV is, in our previous blog ‘Underwater inspection with the Bots’) for drilling support and underwater construction services to develop deep water exploration and development projects worldwide. Manual inspections have limitations of endurance, depths, and ability to carry payloads, and inability to work in hazardous environments. Overcoming these limitations, ROVs have unlimited endurance, provide repeatable data, access higher depths, and can work in hazardous environments. Work class ROV’s The next iteration of ROV called Work class ROV (Source), are powered and electrically enabling some more serious traits in the subsea level. Most of these ROVs are deployed for repair work underwater. Work class ROVs operate in the World’s harshest environments and are therefore designed and built with…...
