Research & Development

The culture of innovation and enterprise at VTV has been sustained by a strong and vibrant research and development wing equipped with an exclusive workshop facility dedicated to the development of prototypes and manufacture of specialized equipment and components. These equipment are designed and developed by VTV engineers, customize based on VTV's specific construction requirement and are amongst the key assets in our endeavor to maintain an international standard of quality and expertise.

VTV today has an in-house design and manufacturing capability for:

• 600T & 1000T Hydraulic Presses
• 400A & 600A Welding Rectifiers
• TIG & MIG Welding Machines
• Power Sources
• 12T & 20T Hydraulic Jacks
• Bottom & Girth SAW Automatic Welding Machines
• 5T-40T Mobile Fabrication Gantry Systems
• Perlite Expanders
• Airlifting Devices
• Positioners
• Swivel Joints for Floating Roof Tank Roof drains
• Gauge Hatches
• Breather Valves
• Flame Arrestors        

The above equipment encompasses every major aspect of the construction process and critical appurtenance for various VTV products and reinforces our commitment towards a high level of excellence in our workmanship.

Another highlight of VTV's R &D efforts is the patented process of spherical tank construction adopted by VTV wherein construction work at grade levels has been maximized.

In 1992, VTV's R&D team embarked on a special project for the development of the 'Varaha Sphere". The 'Varaha' is a character from Indian mythology, manifested as a boar, who lifted the earth from the ocean bed and carried it back to its orbit. This project aimed at evolving a spherical tank construction process that would similarly enable the progressive construction of a sphere from top-downwards. This would enable assembly and welding work of the entire sphere near grade levels, which is of great benefit in terms of quality and safety while reducing construction cycle time. VTV's Construction & R&D group intiated this program with an initial proposal identifying the objectives of the mission and the outline of the new concept. Once the basic process was designed, extensive computer simulations and stability analyses ensued. After a substantial amount of study the first prototype was successfully tested in 1994 and the world's first hydraulically lifted spherical tank was constructed by VTV in 1995. This is now a VTV patented process and has been appreciated by discerning clients, consultants and inspectors in the industry.

VTV has developed a strong automatic welding technology expertise since 1972. VTV's automatic welding expertise is deployed on all shop fabricated equipment, atmospheric & cryogenic storage tanks and mounded pressure vessels, enabling achievement of accelerated delivery schedules and an enhanced quality of weldments. This expertise includes 9% Nickel submerged arc welding used on Ethylene, C2C3 and LNG tanks-a highly specialized skill deployed by a handful of cryogenic tank builders globally.
