On 1 March 2011, the cutter suction dredger (CSD) IBN Battuta arrived in Vietnam for a dredging project located in Vung Ang – Ha Tinh, 350 km South of Hanoi.
Due to the forecast tropical storm NESAT, the vessel interrupted the ongoing dredging project and departed on 28 September 2011 for the port of Da Nang in the South of Vietnam. In the morning of 29 September 2011, the vessel dropped anchor in the port of Da Nang. While the vessel was at anchor, the deck crew (including the Apprentice Dredge Operator) was painting the walls of the pump room, as part of regular maintenance.
At 10:05 AM, the Apprentice Dredge Operator, presumably on his way to join the deck crew for a coffee break, was found stuck in the power operated sliding watertight door (WTD) between the pump room and the engine room. At 10:35 AM, after being transported ashore, the Apprentice Dredge Operator was declared dead at quay by a doctor.
