Bunker Claims Handling &

Mitigation: Strategies Beyond Traditional Fuels

Learn what you need to know and do, to avoid problems, disputes and claims, resolve bunker disputes or defend a claim.

22 Aug 2023 to 23 Aug 2023, Singapore



This 2-day course will provide comprehensive coverage of what you need to know and do, to avoid problems, disputes and claims and devise strategies to resolve bunker disputes or defend a claim. The course will cover testing methodologies beyond the standard ISO 8217, including specialized areas and the latest case studies.


Since the implementation of the IMO 2020 sulphur cap regulations on 1 January 2020, the shipping industry has faced a new set of potential issues relating to bunker quality. There have been numerous complaints of contaminated fuels globally, notably in Houston, Panama & Singapore, causing engine damage, and sludge, fuel pump seizures and engine blackouts. With the forthcoming 2030 and 2050 IMO GHG compliance, alternative marine fuels will become the main fuel of choice. Participants will get to learn the issues experienced by some vessels in using these alternative fuels, in particular, biofuels which are currently the most widely available.
