ROB (Remaining On Board)
ROB stands for Remaining On Board — the quantity of a consumable or cargo still on the ship at a given moment. It is used most often for bunker fuel and lube oil ROB (how much fuel is left), for fresh water, and for cargo ROB (cargo remaining after discharge, e.g. residues or a short-out).
Bunker and lube ROB figures are reported daily in the noon report and are the basis of fuel planning, consumption monitoring and charter fuel accounting. Cargo ROB matters at discharge, where liquid or bulk residues left on board can trigger claims. Accurate ROB reporting underpins fuel budgeting, bunker planning to the next port, and clean settlement between owner and charterer.
ROB is the number that answers "how much is left?" — of fuel, water or cargo. Accurate bunker ROB drives fuel planning and charter accounting; accurate cargo ROB heads off discharge claims. It is a small figure that, reported daily, keeps voyage economics and cargo settlement straight.
