The Digest’s 2026 Multi-Slide Guide to Marine Fuel Quality

The petroleum-centric ISO 8217 standard dangerously lags behind the realities of modern low-carbon marine fuels. While bio-blends introduce unaddressed risks like microbial contamination and cold-flow limitations, emerging fuels like methanol and ammonia demand entirely distinct, specialized handling categories rather than being treated as simple hydrocarbon variants. Even chemically fungible FT diesel presents hidden lubricity challenges. Consequently, operators increasingly rely on interim guidance from class societies to manage the rising frequency of costly fuel-quality and blend-incompatibility incidents.
