Marine Gas Oil (MGO) – Bunker Fuel Inquiry

Gulf-Bunkering provides Marine Gas Oil (MGO) trading solutions for vessels requiring clean-burning distillate fuel with reliable combustion characteristics and straightforward handling properties. Whether you’re coordinating in-port bunkering or offshore fuel supply, our team connects you with compliant MGO that meets your operational specifications and regulatory requirements.

Vessel Compatibility

MGO serves as the primary fuel choice for vessels requiring distillate-grade marine fuel, including:

  • Auxiliary engines across all vessel classes
  • Main propulsion systems on ferries, patrol craft, and coastal vessels
  • Superyachts and megayachts requiring premium fuel quality
  • Offshore support vessels and platform supply boats
  • Government and naval vessels with strict fuel specifications
  • Vessels operating in Emission Control Areas requiring low-sulphur compliance
  • Emergency generators and critical auxiliary systems

Market Positioning and Availability

MGO maintains consistent global availability through established refining and distribution networks at major bunkering hubs worldwide. As a distillate fuel, MGO commands premium pricing relative to residual fuel oils but delivers operational advantages that justify the cost differential for vessels prioritizing reliability, emissions compliance, and simplified fuel management.

Gulf-Bunkering coordinates MGO procurement across key maritime ports, leveraging regional supply infrastructure to secure competitive pricing while maintaining quality standards.

Operational Characteristics

MGO offers straightforward operational handling:

  • Storage: Requires no heating systems; stable at ambient temperatures
  • Handling: Low viscosity enables direct injection without preheating
  • Combustion: Clean-burning properties minimize engine deposits and maintenance intervals
  • Fuel system compatibility: Suitable for modern common-rail and electronic fuel injection systems
  • Cold weather performance: Maintains flow characteristics in varied climatic conditions

The fuel’s distillate composition eliminates the need for centrifugal purification, reducing onboard fuel treatment complexity and supporting efficient vessel operations.

Composition and Specifications

MGO conforms to ISO 8217 standards under DMA and DMB grade classifications:

  • ISO designation: DMA (primary) / DMB grades
  • Viscosity at 40°C: Maximum 6.0 cSt (DMA) / 11.0 cSt (DMB)
  • Sulphur content: 0.10% maximum (ECA-compliant) / 0.50% maximum (global)
  • Density at 15°C: Typically 820-890 kg/m³
  • Flash point: Minimum 60°C
  • Pour point: Typically -6°C or lower depending on grade
  • Water content: Maximum 0.3% v/v
  • Ash content: Maximum 0.01% m/m

All MGO supplied through Gulf-Bunkering’s trading network meets verified ISO 8217 specifications with documented quality parameters.

Environmental Impact and Emissions Profile

MGO delivers the cleanest emissions profile among conventional marine fuels:

  • Significantly reduced particulate matter and black carbon emissions
  • Lower NOx formation compared to residual fuel oils
  • Minimal sulphur oxide emissions, particularly with 0.10% sulphur grades
  • Reduced engine deposits extending maintenance intervals and component lifespan
  • Compatible with selective catalytic reduction (SCR) and exhaust gas cleaning systems

The fuel’s clean combustion characteristics support vessels meeting stringent environmental performance targets and preparing for future regulatory frameworks.

Regulatory Compliance

MGO provides straightforward compliance with current and anticipated maritime fuel regulations:

  • IMO 2020: Fully compliant at 0.50% sulphur maximum for global operations
  • ECA requirements: 0.10% sulphur grades meet North American, European, and other designated ECA zones
  • MARPOL Annex VI: Satisfies sulphur content limitations across all regulatory jurisdictions
  • Port state control: Minimizes risk of non-compliance findings during inspections
  • Future-ready: Positions vessels for anticipated tightening of emissions standards

Vessels using MGO eliminate the operational complexity of fuel changeover procedures when transiting between ECA and non-ECA waters, streamlining compliance management.
