Mitsui O.S.K. Lines has announced that MOL Ocean Bulk Pte. Ltd. will take part in what is described as the world’s first tri-fuel ore carrier project, under a 25-year contract to move iron ore for Vale International S.A.
The agreement, disclosed in a report on 2 October 2026, commits MOL Ocean Bulk, the arm that operates the MOL Group’s overseas Capesize bulker business, to carry Vale cargoes using two vessels for a quarter of a century.
Mitsui O.S.K. Lines made the announcement through its group channels, noting that the arrangement is part of Vale’s Shipping decarbonisation strategy and that the project is billed as pioneering for tri-fuel ore carriers.
The contract duration is notable in length and scope. Spanning 25 years, the deal establishes a long-term supply of tonnage dedicated to Vale International S.A., a subsidiary of Vale S.A., and ties the carriers closely to the miner’s sustainability planning.
The commitment concerns two vessels only, according to the report, and links a conventional bulk operator to an initiative framed as technological and environmental innovation.
Strategic fit and commercial scale
For MOL Ocean Bulk, the arrangement formalises a long-term relationship with a major commodity owner, anchoring two Capesize-scale assets to Vale’s iron ore programme for an extended period.
From Vale’s perspective the contract secures dedicated shipping capacity while aligning freight arrangements with its stated decarbonisation objectives.
Novelty and constraints
The announcement highlights the project’s claim to be the first to apply tri-fuel capability to ore carriers. The precise technical specifications, commercial delivery schedule and regulatory approvals for the vessels were not detailed in the published summary.
Observers will watch how the two vessels are fitted out and certified, and how the long-term voyage patterns and contractual terms are managed over the 25-year span.
The deal is significant for its duration and the branding of the vessels’ fuel capability, but the report contained limited operational detail; it confined itself to the parties, contract length, vessel count and the link to Vale’s decarbonisation strategy.
Mitsui O.S.K. Lines’ disclosure of MOL Ocean Bulk’s role formalises the company as the operator for the concerned Capesize business overseas, while Vale International S.A. is identified as the contracting counterparty.
The partnership adds to a small but growing set of long-duration shipping contracts that pair major cargo owners with operators to support fleet planning tied to environmental commitments.
