UPDATE: Number of containers washed away yet unknown, some dozens, probably.
Container lighter ship, presumably under the name GOLF ARGO, sank in Bangladesh waters at night Sep 12, with 152 containers on board, bound for Kolkata, India. The ship sailed from Chittagong, suffered engine failure and being caught in rough seas, capsized. 14 crew, all Bangladeshi, were rescued in the morning Sep 13 by Bangladesh Navy ship.
No data available on ship’s details, as on all or nearly all Chittagong lighter ships. No news on 152 containers, but surely, some of them or most of them, should be afloat in waters off Chittagong, posing navigational danger.
