With a mission to power the future ocean economy through unparalleled opportunities for business, networking and collaboration, Oceanology International 2026 opens visitor registration today (18th November).

The world’s leading forum for ocean science, engineering and technology returns to Excel London from 10th to 12th March 2026, connecting more than 8,000 attendees and 500 exhibitors from over 80 countries.

Visitors can register for entry now via the Oi26 website for the chance to join ocean professionals from key ocean industries who will unite across a wide range of sectors, including offshore renewables, oil & gas, ocean observation, defence, maritime security, marine science, ports, aquaculture and subsea.

Next year, Oceanology International (Oi) expands its horizons with the debut of COAST, a new coastal and shallow water exhibition zone and conference track. The added focus will ensure that coastal resilience, infrastructure and engineering will be at the heart of an event which once again promises to spotlight breakthrough solutions in ocean exploration, environmental monitoring, sustainable marine engineering and the ocean enterprise.

New attendees will be welcomed from coastal fields, with an invitation to join stakeholders, spanning industry, government and academia, from engineers, hydrographers and geotechnics to energy professionals, oceanographers, site investigators, marine surveyors and many more.

The exhibition floor and the dockside at Oi26 will play host to more than 100 global product and service launches and exclusive announcements as the industry’s leading innovators and most influential associations unveil their latest developments and technology.

As a crucial component of Oi’s commitment to foster learning and connection, a full conference program will reflect the latest topics impacting future ocean technology and economic needs, encompassing a range of content aimed at improving strategies for exploring, protecting and sustainably operating in the world’s oceans and waterways. Mike Enser, Oi Marketing Manager, said: “Anticipation is already building for Oceanology International 2026, so we are delighted to announce that registration is officially open for visitors to book their free entry. We are once again committed to delivering an unmissable three days of exhibition and conference activity, spanning product launches, live demonstrations, workshops, keynote presentations, discussion and one-to-one meetings.
