About IBC

The International Bunker conference (IBC) has a long history supported by the industry. It has remained a proactive forum since its introduction in 1979 and setting sail for the 43 time 23-25 April 2024. 

IBC is committed to the tradition of not only having in-depth presentations of papers on issues of importance to the international bunker industry, but also introduce new and relevant topics for the audience. The IBC program committee aim to take the International Bunker Conference into the future by focusing on relevant topics within the bunker and maritime industry.

Our main asset will remain a close cooperation with industrial partners such as oil companies, ship owners and class societies and our priority will remain to deliver quality-based subject content and a continued network for the IBC delegates.
