The existing offshore platforms in Mumbai High have been operational for more than three decades. Though the design life has exceeded in some cases, oil and gas production still continues as their reservoirs are producing. Hence considerable effort has been spent on maintaining the structural stability and strength of these platforms for the past 10 to 15 years by both ONGC and IEOT in terms of mitigation measures such as underwater strengthening of members, removal of marine growth and many other activities, including load shedding in some cases.
The synergy between IEOT and IIT-M will be continued to develop a technology-based tool for monitoring, assessment, inspection and maintenance of structural integrity of existing platforms to fulfil operational and regulatory requirements for prolonged production of oil and gas, said S Nallayarasu, professor in the department of ocean engineering.
