MumbaiHigh油田是印度最大的海上油气田。MumbaiHighBasin盆地长75公里，宽25公里，位于孟买沿海160公里的阿拉伯海。油气田分为南北两个区块，从1974年开始一直被石油和天然气公司(ONGC)运营。

MumbaiHighNorth(MHN或BHN)平台是一个已经使用了30年的7层钢结构的平台，油气处理能力每天八千桶原油。它与一个无人钻井平台，以及有生活区的BHF、WIN平台通过栈桥相连。BHN平台的作用是分离来自NA和BHF平台的油气，然后将它们分别用海底管道送至陆上。10案例分析

15当时共有384人在BHN及周围的两条多用工作船、一个海上钻井平台NobleCharlieYester上。其中11人死亡，11人失踪，其余人被海上供应船、直升机和印度海军、海岸警备队的船只救起。受影响的井口已经通过井下安全阀关闭，阻止了更大的污染。16案例分析TheDamage
