Bunker Quantity Survey measures fuel quantity and quality onboard vessels. Ship Bunker Supply involves delivering fuel to ships as per requirements. Both ensure accurate fuel transactions and compliance with maritime standards.

Size: Typically measured in metric tons (MT) or barrels (bbl), depending on vessel capacity.

Grade: Common grades include IFO 180, IFO 380, VLSFO, ULSFO, MGO, and MDO.

Viscosity: Ranges from 2 cSt (MGO) to 700 cSt (IFO 380) at 50°C.

Buoyancy: Not directly applicable; fuel density ranges from 820 kg/m³ (MGO) to 991 kg/m³ (IFO 380).

Material: Petroleum-based hydrocarbons, often blended with additives for performance.

Sulfur Content: Varies by grade (0.1% for VLSFO, 0.5% for ULSFO, up to 3.5% for HSFO).

Flash Point: Minimum 60°C (MGO) to 100°C (IFO) for safety compliance.

Pour Point: Ranges from -6°C (MGO) to 30°C (IFO) depending on grade.

Energy Content: Approximately 40-43 MJ/kg for most marine fuels.

Storage Temperature: Typically maintained between 30°C (MGO) and 120°C (HSFO) for optimal flow.
