An Abu Dhabi-controlled products tanker that sank off Yemen had been months overdue for required surveys at the time of the fatal incident, according to new information from classification society Indian Register of Shipping (IR Class).

IR Class chief executive Arun Sharma tells TradeWinds that the 6,760-dwt products tanker Rama 2 (built 1989) was not classed by the society and did not have any valid certificates as of the time of the casualty in late June.
