Latest news from a maritime source:
Must have been short notice on the approach of this storm. ONGC normally evacuate non-essential personnel if a cyclin is threatening their fields.
In the early days of operation at Bombay High (1970s) all drilling stopped during SW Monsoon season and the rigs were pulled into shelter in Bombay.
Later the rigs were put next to platform to drill production wells before the monsoon season (1st June- late Aug/early Sept.)
When the monsoon ended all rigs were waiting to move at the same time. This was known as the “Crazy Week”, causing shortage of boats and Rig movers.
