Gulf-Bunkering facilitates Very Low Sulphur Fuel Oil (VLSFO) procurement for commercial vessels operating globally. As the primary compliant fuel grade under IMO 2020 regulations, VLSFO represents the standard choice for operators seeking cost-effective compliance outside Emission Control Areas.
Vessel Compatibility
VLSFO is suitable for:
- Container vessels and bulk carriers
- Tankers (crude, product, chemical)
- General cargo vessels
- Offshore support vessels
- RoRo and vehicle carriers
- Cruise ships and passenger ferries
- Naval and government vessels
Medium-speed and slow-speed main engines designed for residual fuel operation accommodate VLSFO with minimal modification to existing fuel systems.
Market Positioning and Availability
VLSFO maintains widespread availability across major bunkering hubs worldwide. Competitive pricing relative to distillate fuels makes it the economically preferred option for vessels not operating in ECA-regulated waters. Supply infrastructure at key ports ensures reliable procurement with established quality verification protocols.
Operational Characteristics
Handling: VLSFO typically requires heating to 40-50°C for optimal pumping and 90-100°C for injection, depending on viscosity grade. Fuel systems must maintain adequate temperature control throughout storage and transfer operations.
Storage: Compatible with standard bunker tanks. Attention to fuel stability and compatibility testing is recommended when blending with existing tank contents or switching between suppliers.
Combustion: Combustion properties vary by blend composition. Proper purifier operation and fuel treatment systems ensure consistent engine performance and minimize deposit formation.
Composition and Specifications
VLSFO meets ISO 8217:2017 specifications:
- Sulphur content: Maximum 0.50% m/m
- Viscosity: Typically RMG 380 or RME 180 (at 50°C)
- Density: Maximum 991.0 kg/m³ at 15°C
- Flash point: Minimum 60°C
- Pour point: Maximum 30°C (winter quality available)
VLSFO is a blended fuel product, with composition varying by refinery source and blending components. Quality parameters should be verified through bunker delivery note documentation and independent testing when required.
Environmental Impact and Emissions Profile
VLSFO reduces sulphur oxide (SOx) emissions by approximately 77% compared to traditional 3.5% sulphur HSFO. This reduction directly supports improved air quality in coastal regions and port areas.
Carbon dioxide (CO₂) emissions remain comparable to HSFO on an energy-equivalent basis. Particulate matter and black carbon emissions show moderate reduction depending on fuel composition and combustion efficiency.
Regulatory Compliance
VLSFO satisfies MARPOL Annex VI global sulphur cap requirements implemented January 1, 2020. Vessels operating outside designated ECAs can use VLSFO without additional compliance measures or exhaust gas cleaning systems.
Fuel oil record books, bunker delivery notes, and representative samples must be maintained per IMO regulations. Port State Control inspections verify sulphur content compliance through onboard sampling and testing.
