The Indian Coast Guard conducted the Regional Level Pollution Response Exercise 2025 (RPREX-2025) in Mumbai. The exercise focused on tackling oil pollution at sea. A mock scenario involved a Motor Tanker sending a distress call after a collision with a fishing boat. The collision caused a hole in the tanker and heavy crude oil spillage into the sea. A specialised Indian Coast Guard Pollution Control Vessel and two other ships were deployed. Ships operated in full pollution response configuration. The exercise tested coordination and readiness of all stakeholders. It was conducted as per the National Oil Spill Disaster Contingency Plan.
