Many vessels now rely on Very Low Sulfur Fuel Oil (VLSFO), while others have installed exhaust gas cleaning systems, known as scrubbers, to continue using the higher-sulfur heavy bunker oil while remaining compliant with emissions standards. Furthermore, the formation of asphaltenes—hard, brittle particles—in stored fuel can lead to filter blockages and engine failures, necessitating constant monitoring and the use of dispersant additives to maintain fuel stability.
Heavy Bunker Oil Asphaltenes Formation Risks and Operational Impact
Market Dynamics and Pricing The pricing of heavy bunker oil is intricately linked to the crude oil markets and the balance between residual supply and low-sulfur demand. This transition forced shipowners and operators to adapt their fleets and logistics.
Operational Challenges and Safety Protocols Working with heavy bunker oil presents distinct operational hazards that require rigorous safety protocols. Its high viscosity means it must be heated to specific temperatures, often between 130°C and 150°C, to maintain the necessary flow for pumping and injection into the ship's engines.
Heavy Bunker Oil Asphaltenes Formation Risks and Mitigation
Often referred to as bunker C fuel oil or residual fuel oil, this substance is the bottom fraction remaining after the distillation of crude oil, making it highly viscous and energy-dense. However, the very properties that make it economically attractive also present significant challenges in terms of handling, environmental impact, and regulatory compliance.
