Development areas Three Oil Exploration Areas are situated in the approaches to Mumbai. Number of production platforms and tanker mooring buoys exist in the areas shown on the chart. Underwater construction work on wellheads and pipelines takes place; drilling rigs, diving tenders and support vessels may be encountered in developing areas. Several structures, usually carrying lights, other unlit objects and submerged obstructions, sometimes marked by buoys exist. As these installations are not all charted, vessels navigating in the vicinity should exercise special caution.The Government has established a 500 m safety zone around each installation, which should not be entered; mariners not associated with oilfield operations are strongly advised not to approach within 2½ miles of production platforms.All mariners are advised to keep a constant listening watch on VHF Channel 16 when within 25 miles of all oilfields on the W coast. Distress Within 50 miles of any production platform or drilling rig; any vessels in distress and likely to drift towards them, should ask for assistance through Mumbai coast radio station on 500 MHz and contact standby offshore supply vessels on VHF RT Channel 16.
