Offering the world an unrivalled glimpse into the evolution of the ocean enterprise, Oceanology International 2026 (Oi26) will showcase the future in action for visitors and attendees from 10th to 12th March at Excel London.

An unprecedented 150-plus companies from around the globe will reveal new technologies and solutions, confirming Oi as the ocean science and technology community’s premier event for the industry to introduce cutting-edge innovations and make exclusive announcements.

David Ince, Event Director, Oceanology International, said: “Our community gathers once again in London, united by a common goal – to ensure a healthy, sustainable future for our oceans. For almost six decades, Oceanology International has been the bridge connecting the ocean’s three pillars of industry, academia and government. This year that bridge is stronger than ever, with more launches, increased exhibition space, and the addition of a new COAST focus alongside core Oi features including Ocean Futures, the Technical Conference, and the Dockside Demonstrations.

“We believe that technology is the key to unlocking a brighter future for the ocean. We believe in the power of collaboration to break down barriers and accelerate progress. And we believe in the power of education and inspiration to empower future generations to become the ocean’s guardians.

“So, whether you’re a seasoned oceanographer, a tech entrepreneur, a policymaker, or simply someone who cares about the future of our planet, I invite you to join us at Oceanology International.”

New Launches at Oi26

Among the companies revealing new solutions is Cerulean Sonar, introducing Omniscan 3D, the newest member of the Omniscan imaging sonar family. It delivers the same high-resolution quality as previous models but adds full 3D point-cloud capability, rendering images on a true spatial mesh.
