Bunker fuel supply refers to the provision of fuel for ships, primarily heavy fuel oil or marine gas oil. Ship bunker supply involves delivering fuel to vessels at ports or through bunkering barges. It ensures ships have the necessary fuel for propulsion and operations during voyages.

Bunker Fuel Supply and Ship Bunker Supply typically include the following key specifications and technical properties:

Size: Supplied in bulk quantities, ranging from hundreds to thousands of metric tons, depending on vessel requirements.

Grade: Common grades include IFO 180, IFO 380, and LSFO (Low Sulfur Fuel Oil), with sulfur content varying by regulatory compliance (e.g., IMO 2020 mandates ≤0.50% sulfur).

Viscosity: Ranges from 180 cSt (IFO 180) to 380 cSt (IFO 380) at 50°C, with lower viscosity fuels like MGO (Marine Gas Oil) at 2-10 cSt.

Buoyancy: Density typically between 900-1,010 kg/m³, affecting storage and handling.

Material: Derived from residual or blended petroleum products, often containing heavy hydrocarbons and additives for stability and combustion efficiency.

Flash Point: Minimum 60°C (as per SOLAS regulations) to ensure safety during storage and transfer.

Pour Point: Varies by grade, typically between -6°C to 30°C, influencing cold-weather performance.

Energy Content: Approximately 40-42 MJ/kg, impacting fuel efficiency and consumption rates.
