FORTESCUE AND CMB.TECH SIGN MILESTONE AGREEMENT
FOR 12 AMMONIA BULKERS
TO ACCELERATE ZERO-EMISSIONS SHIPPING
ANTWERP, Belgium, 22 June 2026, 08:00 CET –
CMB.TECH NV (“CMBT”, “CMB.TECH” or “the company”) (NYSE: CMBT, Euronext Brussels: CMBT and Euronext
Oslo Børs: CMBTO) and Fortescue have signed a milestone agreement for the charter of up to 12 ammonia-capable vessels,
marking a significant step towards decarbonising global shipping and advancing the adoption of ammonia as a shipping fuel.
Under the agreement, Fortescue will charter a fleet
of 12 Newcastlemax vessels (210,000 dwt) from Bocimar, the dry bulk division of CMB.TECH.
Up to three of the vessels will be delivered with dual-fuel
ammonia engines and are expected to enter into service by the end of 2026. The remaining nine vessels will be ammonia-ready and can be
converted to operate on ammonia in the future.
If fuelled by green ammonia, the combined fleet could reduce carbon dioxide emissions
by approximately 250,000 tonnes a year compared with conventional marine fuels.
Fortescue Director Integrated Operations,
Katie Charuga:
“The shipping industry doesn’t need more talk.
It needs action.
Green ammonia is one of the clearest pathways to reducing carbon dioxide
emissions from shipping, and these vessels represent a practical step towards that future. By backing new technologies and working with
partners who are prepared to lead, we can help drive the uptake of green ammonia in shipping.
Fortescue’s Green Pioneer demonstration vessel has already shown
that ammonia can be used safely and effectively in marine operations. The next challenge is scaling the use of green ammonia.
By investing in ammonia-capable vessels and working with partners who
share our ambition, we are helping create demand for green ammonia and supporting the technologies needed to reduce emissions from global
shipping.”
Alexander Saverys,
CEO of CMB.TECH said:
“Fortescue
and Bocimar have built a strong partnership over more than two decades, grounded in shared values and a clear commitment to decarbonise
shipping. This agreement marks an important step in showcasing ammonia as a viable marine fuel and advancing the transition to zero-emission
shipping. It also sends a powerful signal to the market, particularly at a time when there is doubt about the decarbonisation of shipping:
our sector can decarbonise at scale. It just takes like-minded, determined partners who walk the talk.”
