Mitsui OSK Lines will operate two 210,000-dwt iron ore carriers for Vale under a 25-year charter, marking the first deployment of tri-fuel propulsion on ships of this size in the long-haul ore trade.

MOL Ocean Bulk, the group's Singapore-based capesize operator, signed the agreement with Vale International. The vessels enter service in 2030 and will carry Brazilian iron ore primarily to China and other global destinations.

The newbuildings can burn ethanol, methanol or conventional heavy fuel oil. MOL described the project as the first involving 210,000-dwt ore carriers with this three-fuel configuration. The design also includes provisions for future LNG or ammonia operation, giving owner and charterer room to shift fuel pathways as availability, regulation and economics evolve.

Why ethanol matters on the Brazil–China lane

MOL said ethanol could cut lifecycle carbon emissions by up to 90% versus heavy fuel oil, depending on the fuel's production pathway. Unlike several emerging marine fuels, ethanol is liquid at ambient conditions, which simplifies handling and bunkering.

That practicality matters for the Brazil–Asia route, the longest major iron ore trade lane and one where fuel bills dominate voyage economics. Each vessel measures 299.95 m long with a beam of 50 m, placing it firmly in the newcastlemax segment that dominates Brazilian ore exports to Asian mills.

The ships will also carry energy-saving equipment intended to reduce fuel consumption, compounding the emissions benefit from the fuel switch.

What does the deal mean for Vale's Scope 3 targets?

The charter forms part of Vale's shipping decarbonisation strategy and directly targets the miner's Scope 3 emissions from seaborne transport — a growing pressure point for mining majors as steelmakers demand greener supply chains.

For Vale, locking in fuel-flexible tonnage on 25-year terms secures decarbonised capacity well into the 2050s while transferring fuel-technology risk to owners willing to manage it. For MOL, the contract guarantees employment for the ships' full economic life in a segment where spot capesize earnings swing violently with Chinese steel output.

The agreement extends a wider wave of Vale-backed tri-fuel ore carrier commitments. The miner has already chartered eight similar 210,000-dwt ships from HMM under 25-year agreements also beginning in 2030, bringing the confirmed programme of methanol-and-ethanol-capable newcastlemaxes to ten vessels.

Who builds the fuel chain?

MOL said it will work with Vale and other partners across ethanol and methanol procurement, supply and bunkering to develop the required fuel chain — an acknowledgement that vessel technology now outruns commercial fuel availability at scale.

For bunker suppliers and port operators along the Brazil–China corridor, ten contracted tri-fuel newcastlemaxes arriving from 2030 signal demand for bioethanol and green methanol supply at Brazilian load ports and Asian discharge hubs, years before those fuel chains exist at volume.

With Vale holding 25-year commitments and MOL building fuel-optionality into the hulls, the Brazil–China ore trade has become the testing ground for alternative-fuel bulk shipping — and further tri-fuel charter announcements from competing miners and carriers look likely as 2030 delivery dates approach.
