Powering the future of marine fuel procurement

Seascale Energy is a joint venture equally owned by Cargill’s Ocean Transportation business and prominent tanker shipping company, Hafnia. As a leading provider of marine fuel solutions globally, Seascale Energy leverages the collective knowledge and experience of both companies, offering exceptional value to all segments of shipowners and maritime professionals around the world.

Seascale Energy: Raising the standard for Marine fuel operations

Seascale Energy is a founding member of the Bunkering Services Initiative (BSI) – a collaborative industry program established to improve accountability, visibility and operational efficiency across marine fuel supply chains.

Developed by a group of leading marine fuel buyers and suppliers, including Seascale Energy (via Hafnia and Cargill as founding participants and members), the BSI combines independent assurance, digital technologies and industry best practice to deliver greater confidence in fuel quantity and quality throughout the bunkering process.

The initiative was launched in the Amsterdam, Rotterdam and Antwerp (ARA) region, Europe’s largest and most globally significant marine fuel hub, and is open to participation from any company active in the bunkering market.

“This concept derives from an industry challenge that required a practical solution for our customers and the broader market. Through strong collaboration with like-minded partners across the supply chain, the initiative has gained momentum since its launch, and we would not be surprised to see similar approaches replicated elsewhere. We are encouraged by early signs of engagement that could unlock further value for the port, its stakeholders, and the industry.” – Peter Grunwaldt (Hafnia) and Olivier Josse (Cargill), CEOs of Seascale Energy.
