Bunkering is the supplying of fuel for use by ships (such fuel is referred to as bunker),[1] including the logistics of loading and distributing the fuel among available shipboard tanks.[2] A person dealing in trade of bunker (fuel) is called a bunker trader.
The term bunkering originated in the days of steamships, when coal was stored in bunkers.[1] Nowadays, the term bunker is generally applied to the petroleum products stored in tanks, and bunkering to the practice and business of refueling ships. Bunkering operations take place at seaports and include the storage and provision of the bunker (ship fuels) to vessels.[3]
Singapore is currently the largest bunkering port in the world.[4]
Two types of Bunkering
The two most common types of bunkering procedure at sea is Ship to Ship Bunkering (STS) in which one ship acts as a terminal whilst the other moors. The second type is Stern Line Bunkering, which is the easiest method of transferring oil, but can be risky during bad weather.[5]
In many maritime contracts, such as charter parties, contracts for carriage of goods by sea,[6] and marine insurance policies,[7] the ship-owner or ship operator is required to ensure that the ship is seaworthy. Seaworthiness requires not only that the ship be sound and properly crewed, but also that it be fully fuelled (or "bunkered") at the start of the voyage.[8] If the ship operator wishes to bunker en route, this must be provided for in a written agreement, or the interruption of the voyage may be deemed to be deviation (a serious breach of contract). If the vessel runs out of fuel in mid-ocean, this also constitutes serious breach, allowing the insurer to cancel a policy[9][10] and allowing a consignee to make a cargo claim. It may also lead to a salvage operation.
