Bagerhat: A vessel carrying unloading equipment capsized in a channel of Mongla Port in the Sundarbans on Thursday night.
The vessel, ‘Helal-1’, sank near buoy No-5 of the port while returning to the port after unloading a consignment of a foreign ship harboured at the buoy.
Harbour master of Mongla Port Commander Md Hasan said the vessel capsized due to a crack developed on its keel while returning to the port.
The owner of the sunken boat launched an operation to salvage the boat, he added.
The port authorities also suspended anchoring of foreign ships to the buoy following the accident.
Meanwhile, no step has so far been taken to salvage ‘MV Shovon-1’, a flyash- carrying vessel which got stuck on a char in the Moronbhola River under Sharankhola Range of the Sundarbans East Zone on November 30.
The flyash-carrying vessel ran aground around 11pm as it was plying the river defying a recently imposed ban on the movement of vessels through the Sundarbans, said Divisional Forest Officer (DFO) of the Sundarbans East Zone Md Saidul Islam.
The vessel was carrying 740 tonnes of flyash, he said.
Contacted, vessel owner Md Saiful Islam said they will start unloading a portion of the flyash first to reduce the weight before pulling back the vessel.
It will take two or three days to make the vessel afloat again, he added.
The Forest Department on Friday formed a three-member probe committee, headed by Assistant Conservator of Forests of Sharankhola Range Md Kamal Uddin Ahmed, to look into the incident.
The committee has been asked to submit its report within three days.
DFO Saidul Islam said as the Mongla-Ghashiakhali channel is facing siltation, the movement of vessels has been limited in day time and the Bangladesh Inland Water Transport Authority (BIWTA) has also been informed that no vessels can ply the rivers inside the Sundarbans at night, too.
The Forest Department will send a letter to the BIWTA to remind them of the restriction on the movement of vessels inside the Sundarbans, he added.
No vessel will be allowed to go through the Sundarbans at night, the DFO added.
