Bunker on Board (BOB)

Bunker on Board (BOB) refers to the amount of fuel a vessel has available for propulsion and onboard operations. It is commonly measured when a vessel is delivered to or redelivered from a charter, arrives or departs a port, or at the end of a voyage. The quantity of BOB directly affects voyage costs and is often included in charter party settlements, where the charterer pays for the fuel remaining on board or is reimbursed for the fuel consumed. Accurate BOB measurements are important for fuel management, voyage planning, and financial reconciliation.
