January 25, 2017: Oil and Natural Gas Corporation (ONGC) started its search for "Black Gold" in Indian waters in 1976 and is presently running greater than 265 offshore fixed coat systems in water depths varying from 25 to 90 meters. A lot of these platforms had a 25-year design life, with a number of them having already outlasted this turning point and many more approaching it. In addition, modifications on many of the systems have been made because of upgraded design criteria or due to revamping jobs executed for boosted oil recovery. Therefore, the requalification of these frameworks was very crucial to make certain ongoing oil production, therefore sustaining the power supply needed for the national growth. ONGC also wished to stay clear of mounting brand-new systems at a net price of USD 25 million per platform.

ONGC invested USD 150 million to evaluate its jacketed platforms for extended fit for use and reinforce the platforms as required to fulfill industry safety and security needs. ONGC made use of SACS for design-level evaluation to perform detailed architectural evaluations and SACS Collapse for supreme stamina analysis. This modern technology entered into ONGC's method for platform life extension/requalification, which included 10-15 years to the typical life of each structure.

The analysis included damage modeling, member/joint part fortifying, additional pile modeling, and dirt merging, as well as substantial lots modeling to recommend devices elimination if essential. SACS and CAVITY Collapse, with the efficient multi-run option, enabled multiple evaluations with parametric variants to be carried out at the same time and allowed ONGC to maximize the strengthening/mitigation actions, saving at least 12 resource-hours each platform.

Dinesh Kumar-GGM, head frameworks, IEOT-ONGC, India, claimed, "The large range of applications provided under the umbrella of Bentley modern technology has actually caused ONGC having the ability to manage our overseas assets much more efficiently.
