The lighter ship 'Bilash' sank with a cargo coal on board sank at Bagerhat’s Mongla in the Harbaria area after having received the cargo from the 'Observator'. The bulkcarrier had anchored at Haribaria – 6 carrying 24,500 metric tonnes of coal on Apr 13, 2018. The 'Bilash' with a capacity of 1,000 metric tonnes received 775 metric tonnes from the vessel and set off for Dhaka’s Mirpur but ran aground on a sandbar nearly 60 nautical miles from the port at Harbaria-5. The crew contacted the port for help. The 'Shipsha' was sent to the location to try and rescue the 'Bilash', but the tides overturned the ship around 3 a.m. and caused it to sink. The coal load was not released and there was no concern of an environmental threat. Parts of the lighter ship were still visible and recovery operations were ongoing.
