Gaining Ecosystem Advantage: Bunker Optimisation

Bunkers are the single largest and highly volatile operational expense for the shipping industry.

Efficient use of bunker and bunker costs are susceptible to performance-based improvements and have a direct impact on carbon emissions and the bottom line. Hence, aligning on a proper strategy and reducing those expenditures is critical for companies that want to create and sustain a competitive advantage.

One quick win would be to use technology to improve and optimize fuel consumption and purchasing.

So, how can you adopt a more deliberate, strategic, and data-driven approach to bunker management with technology?

Attend this webinar where Fernando Alvarez reveals how you can optimise your bunker procurement strategy while planning a voyage with seamless and powerful integration between  Dataloy VMS and BunkerPlanner.
