About oil tanker operations
PortWatch classifies vessels by AIS-reported type. The Oil Tanker classification covers crude tankers, product tankers, chemical parcel tankers, LNG and LPG carriers. Operations are characterised by dedicated jetties or single-point moorings (SPMs), articulated marine loading arms, vapour return systems, and stringent fire-fighting and oil-spill response protocols. Custody transfer relies on flow meters and tank-gauging systems calibrated to OIML and API standards. Across the indexed dataset there are currently 27 vessels in this category calling at 27 distinct ports, with the heaviest concentrations at the gateways listed in the panel above.
Operationally, oil tanker tonnage is measured in cubic metres of liquid throughput, and the design of any port that handles this tonnage in volume reflects the cargo’s physical and chemical characteristics. Berth depths, crane outreach, yard layout, hazardous-materials zoning, and the connecting rail or pipeline infrastructure are all dictated by what the vessel is carrying. Because of this, the same shipping company will typically use very different terminals for very different parts of its fleet â even within the same port complex.
