数字化技术助海上石油平台焕发新生

Core Viewpoint - India is increasing its oil extraction efforts to achieve energy independence, leading to a demand for new offshore facilities and technologies to enhance oil recovery [1] Group 1: Company Initiatives - The Oil and Natural Gas Corporation (ONGC) is the largest state-owned oil and gas exploration and production company in India, actively supporting this strategic initiative [1] - ONGC is advancing multiple secondary development projects in oil fields, which require structural modifications to existing platforms [1][3] - The company is conducting structural assessments on 18 unmanned wellhead jacket platforms to ensure they can support the proposed installations [1][4] Group 2: Structural Integrity and Challenges - The updated design standards have increased hydrodynamic loads on platform structures by 20% to 30%, presenting significant challenges for ONGC [4] - The company recognizes that some structural components may exceed stress limits due to changes in drag coefficients and marine biofouling parameters [4] - ONGC requires comprehensive offshore structural analysis techniques to ensure safety and environmental protection while accommodating new loads [4] Group 3: Technological Solutions - ONGC utilizes SACS software for modeling platform structures and conducting both linear and nonlinear limit strength analyses [5] - The analysis includes extreme storm conditions and various load combinations, revealing that most platforms cannot safely support new components [5][6] - The software allows for efficient identification of failure modes and determination of reinforcement or remediation strategies [5][6] Group 4: Digitalization and Efficiency - The use of SACS has enabled ONGC to conduct multiple structural strength analyses simultaneously, saving 30% to 40% of analysis time [6] - Digital modeling and analysis have optimized the structural integrity of existing platforms, reducing environmental risks and preventing catastrophic incidents [6][7] - By retrofitting existing platforms to meet new design standards, ONGC can save installation costs of $30 million to $40 million per new platform [7]
