Five years since the IMO 2020 global sulphur cap came into effect, the VLSFO market has matured considerably — but quality variability, supply chain complexity, and the technical demands of blending compliant fuel remain significant challenges for shipowners and bunker buyers. At our Rotterdam and Fujairah terminals, we have refined our VLSFO blending programme to produce consistent, ISO 8217-compliant product from well-characterised component streams — giving clients confidence in the fuel their vessels receive. In this article, we explore what the post-IMO 2020 bunkering market looks like at the world’s two most important bunkering hubs, and what shipowners should look for in a reliable fuel supplier.
