SMM 2026 was the best-attended edition in the fair's history, but the growth was marginal and the footprint barely moved. What changed was inside it: a dedicated Naval Hall, a new Energy Efficiency Hub, and security displacing decarbonization at the top of the agenda. SMM 2028 runs 5-8 September.
September 1-4, 2026 | Hamburg Messe und Congress, Hamburg, Germany | ~2,300 exhibitors from 66 countries, 70%+ international | 50,000+ participants from 134 nations (preliminary) | 90,000+ sqm across 12 halls | 26 national pavilions | Next edition: September 5-8, 2028
SMM 2026 closed on Friday as the best-attended edition in the fair's history, and the numbers that got there are the least interesting thing about it. Based on preliminary figures extrapolated during the final day, more than 50,000 participants came to Hamburg from 134 nations, up from 48,000 from more than 100 countries in 2024. Around 2,300 exhibiting companies took space, up from more than 2,200. The reported footprint remained broadly unchanged at more than 90,000 square meters across twelve halls.
So the growth was real but marginal, roughly 4% on participants and 5% on exhibitors. What actually changed at SMM 2026 happened inside that broadly unchanged footprint. An entire hall was handed over to naval and maritime defense for the first time. A new dedicated area was carved out for energy efficiency. And the running order of the industry's priorities, which for three editions has read decarbonization first and everything else after, was visibly rewritten in front of 50,000 people.
The clearest signal was structural. Hamburg Messe und Congress consolidated maritime security and defense into a purpose-built Naval Hall in B8, pulling the MS&D Expo, the MS&D conference and a central Naval Stage into one place. Previous editions scattered that content across the grounds. More than 50 specialist companies and organizations exhibited inside the hall, with a further 150-plus dual-use suppliers spread across the rest of the fair.
"With the Naval Hall, we are now taking the next step by creating a dedicated hall and stage for this important sector," Claus Ulrich Selbach, Vice President at Hamburg Messe und Congress, said when the format was announced in July.
Exhibitors bought it. "SMM is an important platform for us to engage personally with partners and suppliers. The new Naval Hall is an excellent addition and has been very well received by visitors," said Oliver Grün, Spokesman of the Naval Systems division at Rheinmetall AG.
The MS&D conference ran on the Naval Stage across 3 and 4 September, working through underwater systems, European cooperation in naval shipbuilding, technological sovereignty, autonomous systems and defense procurement. Its most-watched slot was Vice Admiral Jan Christian Kaack's keynote on the Thursday, his final public appearance as Chief of the German Navy. His argument was about speed rather than capability: given the current security situation, proven solutions need to be procured far faster than they currently are, and crewed and uncrewed systems need to work together much more closely than they currently do.
Rear Admiral Christian Bock, head of the Bundeswehr Innovation Center, framed the show itself as part of that pipeline: "SMM and MS&D are important platforms for identifying new technologies at an early stage and bringing innovations into operational use more quickly."
The commercial side of the floor said the same thing in plainer language. "Decarbonisation remains important, but safety at sea and the protection of sea lanes are currently the number one priority," said Klaus Deleroi, Managing Director of gearbox maker REINTJES.
That sentence is the recap in miniature. Not decarbonization abandoned. Decarbonization demoted to second on a list it used to own outright.
The second structural change ran in the opposite direction, and it is easy to misread. SMM gave energy efficiency its own dedicated exhibition space for the first time, the Energy Efficiency Hub, where 24 companies from Europe, Asia and the Middle East shared 300 square meters of floor with an adjoining Energy Efficiency Stage. The Global Maritime Environmental Congress ran on that stage on 2 September, with green shipping corridors as its organizing idea.
A dedicated hub is not what a fair builds for a topic that is fading. It is what a fair builds for a topic that has stopped being visionary and started being purchasable. Exhibitors in the hub described exactly that transition.
"What stood out to us in particular was how specific the discussions have become: shipping companies are actively looking for solutions to improve fleet efficiency and are increasingly exploring technologies such as wind propulsion that can already be deployed today," said Ada Ak, Sales Engineer at BAR Technologies.
The phrase doing the work there is "can already be deployed today." Efficiency retrofits, wind assistance and fleet optimization sell now, against fuel bills that exist now. Alternative-fuel newbuildings are sold against the economics of a global fuel standard and carbon price that, as of the week SMM opened, had still not been adopted.
That is the backdrop nobody on the floor could ignore. The IMO's extraordinary MEPC session in October 2025 adjourned on a 57-49 vote without adopting the mid-term measures at the heart of the Net-Zero Framework, the global fuel standard and greenhouse-gas pricing mechanism. It was scheduled to resume on 4 December 2026, around three months after SMM, subject to confirmation at MEPC 85. Owners were being asked to commit capital to twenty-five-year assets under a pricing regime that had been deferred once and could be deferred again. Everllence chief executive Dr Uwe Lauber's line at the opening event went straight at it: the technology is ready, and what the industry now needs is a credible IMO Net-Zero Framework that gives investment the certainty to move.
Alfa Laval read the same room more optimistically. "SMM 2026 has been an excellent week for Alfa Laval, with a high level of engagement and substantive conversations across the industry. What stood out was the strong focus on turning ambition into action," said Helena Sannicolò, Vice President Marketing and Communications, Ocean Division.
The third shift was quieter and, for exhibitors, probably the most useful to note. The AI conversation at SMM 2026 stopped being about AI.
"At SMM 2026, we can clearly see that the conversations are becoming more specific: customers are asking less about the potential of AI and more about ready-to-use solutions for collision avoidance on board. The quality of the discussions was noticeably higher this year," said Patrick Haebig, Senior Sales Manager EMEA North at SEA.AI.
That is the sound of a category graduating. Two editions ago the maritime AI pitch was a capability demo; at this one it was a procurement conversation about a specific function on a specific bridge. The Maritime Future Summit worked the same ground, with moderator Michael Meyer arguing that the interaction between artificial and human intelligence is one of the key factors in moving the industry forward. Fleet optimization, predictive maintenance and collision avoidance were where the substance sat.
Post-show reports from maritime fairs often describe atmosphere rather than transactions. SMM 2026 produced both. A partial list of what was signed or unveiled on the floor:
Nineteen young companies exhibited through Start-ups@SMM. One new side event broadened the fair's remit: ALL ABOUT PORTS, a two-day conference and exhibition covering port digitalization and AI, sustainability and propulsion, infrastructure and logistics, port security and process automation, held at the CCH on 2 and 3 September in parallel with SMM and LogiNext Germany. Its first edition drew more than 1,100 participants, and Hamburg Messe has already scheduled a second for 17-18 November 2027. The Maritime Career Market returned, running across two full exhibition days aimed at students and early-career professionals in an industry with a well-documented crewing and engineering shortage.
The internationalization story is where SMM's growth actually showed up. The participant-nation count rose from more than 100 in 2024 to 134 in 2026, and more than 70% of exhibitors came from outside Germany. Twenty-six national pavilions represented around 30 countries, with India, Cyprus and Brazil taking their own pavilions for the first time.
India's was the substantial debut. The Ministry of Ports, Shipping and Waterways organized two official pavilions for a contingent expected to include roughly 35 Indian exhibitors, and the delegation converted the trip into signed paper:
Vijay Kumar, Secretary at India's Ministry of Ports, Shipping and Waterways, used the opening event to set out the Maritime Amrit Kaal Vision 2047 investment programme. For a fair whose exhibitor base has long been European and East Asian, a first-time South Asian pavilion arriving with a state-backed capex story is a more meaningful data point than the headline attendance figure.
Other pavilion organizers were blunt about why they came. "SMM is a unique meeting place for the maritime industry. Our exhibitors held numerous discussions with international business partners that will lead to new collaborations. We will be back in 2028 with a strong Danish presence," said Mie Jakobsen, Deputy CEO and Head of Marine at the Danish Export Association. Junichi Hirata, Managing Director at CAJS in Japan, described SMM as "the Maritime Olympics!"
Three things carry forward from this edition.
Hall position now matters more. With the publicly reported footprint broadly unchanged while the show introduced more strongly defined specialist areas, choosing the right hall may matter as much as stand size in 2028. The halls now signal something they did not signal in 2024, and a naval-adjacent supplier in a general engineering hall is a harder find than it used to be.
Sell what ships this year. The exhibitors reporting the best conversations were the ones with deployable product: wind assistance, efficiency retrofits, collision-avoidance systems, service agreements. The buyers were noticeably less interested in roadmaps while the IMO's fuel standard and carbon price remained unadopted. If your 2028 pitch is a 2032 technology, pair it with something a superintendent can buy in the same conversation.
Dual-use is now a category, not a footnote. Fifty-plus companies in the Naval Hall and 150-plus dual-use exhibitors elsewhere is a large enough presence that commercial marine suppliers should be deciding deliberately whether they present a defense-adjacent capability, rather than discovering at the show that their competitors already do.
SMM 2028 runs 5-8 September 2028 at Hamburg Messe und Congress in Hamburg, Germany. The standalone MS&D Conference & Expo runs earlier, on 8-9 December 2027 at the CCH - Congress Center Hamburg, alongside the Global Security and Defence Summit. ALL ABOUT PORTS returns to the same venue on 17-18 November 2027, three weeks ahead of it.
Hamburg's maritime and offshore calendar does not wait that long. WindEnergy Hamburg 2026 runs 22-25 September 2026 at the same venue, and covers a good share of the same offshore supply chain. You can browse everything else on the Hamburg and Marine & Maritime pages.
SMM 2026 ran Tuesday 1 September through Friday 4 September 2026 at Hamburg Messe und Congress in Hamburg, Germany. It is a biennial fair, held under the patronage of German Chancellor Friedrich Merz, with the guiding theme "SMM - driving the maritime transition."
More than 50,000 participants from 134 nations attended, a record for the fair and up from 48,000 from more than 100 countries in 2024. These are preliminary figures, extrapolated by the organizer from the final day of the event as of noon. Around 2,300 exhibiting companies from 66 countries took part, more than 70% of them from outside Germany, across more than 90,000 square meters in twelve halls.
Maritime security and resilience overtook decarbonization as the dominant issue. Organizers introduced a dedicated Naval Hall in B8 combining the MS&D Expo, the MS&D conference and a Naval Stage, with more than 50 specialist exhibitors inside and over 150 dual-use suppliers elsewhere on the grounds. Decarbonization, digitalization and competitiveness remained central, but were increasingly discussed alongside security rather than ahead of it.
A new dedicated exhibition area, the first time SMM gave energy efficiency its own space. Twenty-four companies from Europe, Asia and the Middle East exhibited across 300 square meters, covering wind propulsion, fleet optimization and efficiency retrofits, supported by an Energy Efficiency Stage that hosted the Global Maritime Environmental Congress on 2 September.
A new two-day conference and exhibition for the global port industry, staged by Hamburg Messe und Congress at the CCH on 2 and 3 September 2026 in parallel with SMM and LogiNext Germany. Its first edition drew more than 1,100 participants across digitalization and AI, sustainability and propulsion, infrastructure and logistics, port security and process automation. The second edition is scheduled for 17-18 November 2027.
Announcements on the floor included two 14,000 TEU container ships ordered by Peter Döhle at Hudong-Zhonghua Shipbuilding on 1 September, four Long-Term Service Agreements between Everllence PrimeServ and TT-Line covering two RoPax newbuildings plus the Nils Holgersson and Peter Pan, two hydrogen fuel-cell 3,000-dwt bulk carriers ordered from Chowgule Shipbuilding by Norway's Green Maritime Infrastructure Group, and a new roughly 17,000-dwt semi-liner multipurpose design from Deltamarin and Toepfer Transport. India's delegation also signed a maritime-centre cooperation MoU with Germany and two GRSE MoUs with DNV and Damen Technical Cooperation, and the Indian Register of Shipping announced a Hamburg office.
SMM 2028 runs 5-8 September 2028 in Hamburg. The standalone MS&D Conference & Expo runs 8-9 December 2027 at the CCH - Congress Center Hamburg, and ALL ABOUT PORTS returns there on 17-18 November 2027.
