Seascale Energy, the marine fuel procurement joint venture between Cargill’s Ocean Transportation business and Hafnia, on Monday (21 September) announced that co-CEO Olivier Josse (OJ) will retire from Cargill on 14 December 2026 after 36 years. Gaetan Perret, Head of Marine Fuel Procurement, West, will succeed him as Vice President, Marine Fuels at Cargill and as co-CEO of Seascale Energy, alongside Peter Grünwaldt, effective the same date. Olivier Josse joined Cargill in 1990 and has held leadership roles across the company’s trading and chartering activities, joining Ocean Transportation in 2006 and serving on its leadership team since 2010. He led the establishment of Seascale Energy in 2025 and has served as co-CEO since the joint venture began operations. “OJ has spent 36 years building businesses and developing people at Cargill, most recently through Seascale Energy,” said Jan Dieleman, President of Cargill’s Ocean Transportation business. “He leaves the platform in a strong position and with a successor who helped build it. Gaetan knows this market, knows our customers and knows what Seascale was set up to do.” “Seascale was built to give the market scale and transparency, and that remains the job,” said Olivier Josse. “After 36 years, the timing is right for me personally. Deciding to retire says everything about the strength of the platform, the direction of the business, and the wonderful people in it. The volumes, the membership and the pipeline all point in the same positive direction – and as a co-founder, I would not be stepping back at this time if I thought otherwise. It is now time for my close colleague Gaetan Perret to take on the baton, and I congratulate him, and wish both him and Peter all the best in taking Seascale onto its next steps. It has been a fantastic experience working with both and the wider team.” “OJ and I started this venture together with an amazing team, and I am grateful for his partnership and friendship in the last years,
