Oceanology International Drives Innovation to Power the Future Ocean Economy

World’s foremost ocean innovation and technology showcase returns to London’s ExCeL with expanded focus on coastal and shallow water solutions and expertise.

London, UK – 18th August 2025 – Oceanology International, the world’s leading forum for ocean science, engineering and technology, returns to London’s ExCeL from 10th to 12th March 2026, to connect the global ocean community for three unmissable days of innovation, networking and thought leadership. Welcoming engineering, survey and science professionals from ocean industries including offshore energy, ocean observation and defence, the 2026 edition will spotlight breakthrough solutions driving the future of ocean exploration, environmental monitoring and sustainable marine operations.

Adding a fresh dimension for 2026, COAST is launching to increase the attention on the critical coastal and shallow water sectors. The new focus will ensure that coastal resilience, infrastructure and engineering will be at the heart of an event which once again promises to connect the world’s ocean engineering, technology and science communities from more than 80 countries.

COAST will further enhance the traditionally diverse Oceanology International (Oi) program, across both the exhibition and conference by highlighting breakthrough developments in coastal protection, erosion control, sediment transport analysis, shoreline stabilisation, and climate adaptation that support sustainable coastal development and ecosystem protection.

Awarded the title of RX UK Show of the Year in 2024, the next edition in the 55-year history of the biennial event will demonstrate how Oi continues to evolve and adapt in response to the demand for new solutions and collaboration in the energy transition and blue technology markets.

First-time exhibitors and visitors in coastal fields are invited to join stakeholders, spanning industry, government and academia, from engineers, hydrographers and geotechnics to energy professionals, oceanographers, site investigators, marine surveyors and many more, who will unite across a wide range of sectors, including renewables, offshore oil & gas, defence, maritime security, marine science, ports, aquaculture and subsea.

There will also be a full content program, reflecting the latest topics impacting future ocean technology and economic needs and encompassing a range of content aimed at improving strategies for exploring, protecting and sustainably operating in the world’s oceans and waterways.

David Ince, Oi event Director, said: “We are delighted to announce that plans for another defining, inspirational and highly relevant Oceanology International in 2026 are gathering momentum. Following Oi24, which exceeded all expectations, we remain committed to fulfilling our mission for the global marine science and ocean engineering and technology communities to act as the premier facilitator of ocean connection.

“The launch of COAST at Oi26 is in response to the critical challenges facing our coasts in the face of storms, flooding, erosion and rising sea levels, highlighting the essential engineering developments which are ensuring healthy ecosystems, strong sea defences, effective maritime operations, thriving ports and harbours, and secure offshore energy infrastructure.

“COAST is a new gateway for leading companies in the field to join the global gathering at Oi and gain access to a highly targeted and engaged audience – to demonstrate their solutions for dynamic nearshore environments and engage with coastal engineers, hydrographic surveyors, geospatial analysts, port and harbour engineers, environmental consultants, marine data specialists and coastal planners.

“For our visitors, there will be new opportunities to discover cutting-edge solutions, connect with global experts and experience live demonstrations that will put them ahead of the curve in marine, coastal and shallow water innovation.”

Oi26 has also announced its ‘Call for Content’, encouraging individuals and organisations to contribute to the event’s technical conference program by submitting papers across a wide range of topics.

Prospective speakers are invited to submit their proposals by 30th September via the Oi26 website. Submissions will be reviewed by a panel of experts in the field and selected speakers will have the chance to present their ideas, research findings and case studies to a global audience of peers, stakeholders, and potential collaborators.

Ahead of visitor registration opening in November, there is an opportunity to register interest now by clicking on Take Part on the Oceanology website homepage.

Oceanology International returns to London’s ExCeL from 10th to 12th March 2026, uniting more than 8,000 attendees and 500 exhibitors from across the globe. This year, the event expands its horizons with the debut of COAST, building on Oi’s commitment to connect the entire ocean and coastal community.
