Gibson tanker report – Diesel Drought

The recent Gibson Shipbrokers tanker report highlights a looming diesel drought, shifting focus from Middle East geopolitical tensions to a critical supply-side shock in global energy markets. As refining margins fluctuate, the availability of ultra-low sulfur diesel is tightening, impacting tanker demand and vessel routing strategies. With major hubs like Singapore and Fujairah monitoring inventory levels closely, shipping companies must navigate this volatility. This supply constraint threatens to disrupt bunkering schedules and operational efficiency for global tanker fleets.

Operational compliance remains paramount under MARPOL Annex VI, which mandates strict sulfur content limits for marine fuels. As the industry faces potential diesel shortages, vessels must ensure that any alternative fuel blends or bunker supplies remain fully compliant with Regulation 14 of MARPOL Annex VI. Classification societies, such as DNV or Lloyd’s Register, emphasize that fuel quality documentation, including Bunker Delivery Notes, must be meticulously maintained to avoid port state control detentions. Failure to secure compliant fuel could trigger severe non-compliance penalties under international maritime law.

Chief engineers and second engineers are directly affected by these fuel supply instabilities. These officers must prioritize rigorous fuel testing and onboard management of fuel oil systems to mitigate risks associated with lower-quality or blended fuels. It is essential to monitor fuel viscosity and compatibility closely during bunkering operations. Maintaining detailed records and ensuring engine room readiness for potential fuel switching are critical steps to prevent mechanical failure and ensure continued vessel performance during this period.
