Validating RRBO Performance for Decarbonisation
At Gulf Marine, sustainability and performance go hand in hand. Recognising that base oils comprise 80% - 90% of marine cylinder oil formulations, we have initiated a dedicated research programme to evaluate how re-refined base oils (RRBO) can reduce the carbon footprint of marine lubricants without compromising engine performance. Our exploratory research combines laboratory bench tests with 4,000-hour sea trials to validate the technical feasibility of RRBO integration. While this technology is not yet mature for commercial deployment, our findings establish a robust technical foundation for potential future adoption Gulf Marine experts Obydur Rahman and Vincent Ang discuss RRBO performance and decarbonisation potential with lubricant expert, Rafe Britton.

Episode 1: Re-refined Base Oils: The Future of Marine Lubrication
Obydur Rahman, MSc (Materials Science & Engineering), Technical Manager for Middle East and South Asia, explains how advanced re-refining transforms used lubricants into high-purity base oils that can meet close to API Group II specifications. He explores why RRBO represents a genuine circular alternative to virgin base oil, and identifies key challenges for adoption.

Obydur Rahman, MSc (Materials Science & Engineering), Technical Manager for Middle East and South Asia, shares findings from Gulf Marine’s 4,000-hour sea trials comparing cylinder with 20% RRBO blended against virgin-based formulations. The results show identical linear wear rates of 0.02 mm/1,000 hours and comparable deposit control, confirming RRBO can deliver strong engine protection while supporting more sustainable lubricant production.

Episode 3: Lubricants: The Overlooked Decarbonisation Opportunity
Lubricants are often overlooked in decarbonisation plans, yet they represent a significant opportunity to lower lifecycle carbon emissions in marine applications.
Vincent Ang, Global Formulations and Sustainability Manager, explains how incorporating re-refined base oils can reduce lifecycle CO₂ emissions by 80% compared to virgin base oils. He also explores how low viscosity formulations could potentially improve fuel efficiency, positing lubricants as a practical lever for maritime decarbonisation.
