SMM 2026: The Maritime World's Technology Hub Evolves Again

When the doors open at SMM 2026 exhibition in Hamburg on September 1, 2026, more than 50,000 maritime professionals from over 120 countries will stream into the Hamburg Messe exhibition halls to conduct business, evaluate technology and reconnect with colleagues from around the globe.

For Uli Selbach, Vice President Exhibitions Maritime & Energy at Hamburg Messe, that moment never gets old. "After preparing this event for two years," he says, "standing on the first floor and watching everyone pour into the halls is always a very emotional moment."

After more than a decade leading the world's largest shipbuilding and maritime technology exhibition, Selbach has witnessed both the industry's recovery and its transformation. When he assumed responsibility for SMM in 2014, the global maritime market was still feeling the effects of the financial crisis. Today, he sees an entirely different landscape.

"The industry has been recovering every time," Selbach says. "Today, it's thriving. Shipowners are investing in new ships. They're investing in retrofits. Suppliers are busy. Even the shipyards are smiling."

That resurgence is reflected across SMM itself. More than 2,200 exhibitors will occupy the exhibition grounds, reaffirming SMM's position as arguably the most comprehensive gathering of the global shipbuilding supply chain anywhere in the world.

"If I define SMM," Selbach says simply, "it's about technology. It's the number one technology hub platform worldwide."

While SMM has always been known for its exhibition halls, the event continues to evolve into something much broader.

Over the past several editions, Hamburg Messe has moved nearly all of its conference programming directly onto the show floor. Five open stages now host presentations and discussions ranging from the Global Maritime Environmental Congress (GMEC) to offshore energy, digitalization, maritime security and future technologies, all included with a standard exhibition ticket.

The result is a more integrated experience that keeps visitors immersed in both technology and conversation throughout the week.

"We always have to move on," Selbach says. "Otherwise, you'll die."

Defense to the Fore

Among the most visible additions for 2026 is an expanded emphasis on naval and defense technologies.

Responding to increased defense spending throughout Europe and NATO countries, SMM will dedicate an entire exhibition hall to maritime security and naval innovation, complete with a four-day conference program centered on defense technologies and procurement.

Selbach estimates that roughly 250 exhibitors represent dual-use technologies capable of serving both commercial and naval markets.

The dedicated Naval Hall will also introduce a new area designed specifically for companies entering the maritime defense sector for the first time.

"Many companies are discovering that their products don't only belong in automotive or industrial manufacturing," Selbach explains. "They can also be used aboard ships or submarines."

Major naval players — including Rheinmetall Naval Systems, ThyssenKrupp Marine Systems, Damen, Fincantieri and others — will participate alongside startups and procurement representatives from the German Navy, creating an ecosystem that spans established defense contractors and emerging technology suppliers.

Beyond Future Fuels

Decarbonization remains central to SMM, but Selbach believes the industry's conversation has matured. A decade ago, discussions centered on identifying the future fuel. Today, the consensus is far more nuanced.

"There will not be one solution," he says. "It won't simply be ammonia or methanol or wind propulsion."

Instead, SMM 2026 introduces an expanded Energy Efficiency Hub in Hall A2, bringing together propulsion technologies, efficiency solutions and fuel innovations under one umbrella.

Selbach also continues to advocate for maintaining an open dialogue around nuclear technologies.

"If we're talking about zero emissions," he says, "we also have to look at what the nuclear industry can contribute—whether that's small reactors or technologies supporting hydrogen production."

For SMM, technological neutrality remains a guiding principle.

A New Focus – Ports

Perhaps the most significant addition outside the exhibition halls is ALL ABOUT PORTS, a new two-day event running alongside SMM at Hamburg's adjacent Congress Center.

Unlike traditional port conferences that focus on container terminals or cargo handling, Selbach says the new event takes a comprehensive view of port operations—from bunkering and customs to passenger terminals, digital logistics and critical infrastructure.

The event also hosts the European regional meeting of the International Association of Ports and Harbors (IAPH), underscoring the growing convergence between ports and shipbuilding.

"Ports aren't shipbuilding," Selbach acknowledges. "But there are so many touchpoints that it simply makes sense to bring everyone together."

The Value of Being in Hamburg

Despite virtual meetings becoming commonplace after COVID-19, Selbach remains convinced that face-to-face interaction has only become more valuable. "Zoom or Teams doesn't replace personal meetings," he says. "People want to see each other."

Ironically, he argues that gathering thousands of professionals in one place may actually reduce overall travel.

"If you come to SMM for four days and plan correctly," he says, "you may save yourself four months of traveling around the world."

That philosophy extends beyond business meetings. Hamburg Messe intentionally encourages exhibitors to keep conversations going after exhibition hours through stand receptions and evening networking events held throughout the fairgrounds.

For Selbach, SMM has become something of an annual reunion for the maritime industry.

"It's like returning to school after summer holidays," he says. "You come back and meet all your friends again."

That sense of community, combined with an increasingly diverse technology showcase spanning commercial shipping, naval defense, energy transition and port operations, explains why SMM continues to set the benchmark for global maritime exhibitions.

Or, as Selbach puts it, if you're not in Hamburg this September, you may experience exactly what his daughter calls FOMO—the fear of missing out. In the maritime business, he suggests, missing SMM increasingly means missing where the industry's next conversations begin.
