Oceanology International

What Oceanology International does

Oceanology International (Oi) is a biennial marine science and ocean technology exhibition and conference series established around 1970, organized by Reed Exhibitions Limited (RX), a wholly-owned subsidiary of RELX Group plc. The flagship Oi London event is held at ExCeL London on the Royal Victoria Dock, complemented by a regional counterpart, Oi Americas, launched in San Diego, California in 2022. The event connects ocean-technology vendors with buyers across offshore energy (renewables and oil & gas), ocean observation, defence and maritime security, marine science, ports, aquaculture, and subsea sectors. The Oi24 edition attracted 7,536 unique attendees from 91 countries, 443 exhibiting companies from 31 countries, 166 conference speakers, and 175+ dockside demonstrations across 19,000 square metres of exhibition space.

The portfolio extends beyond physical events into digital products and specialized zones, including the Inside Oi year-round news and insights platform, an Exhibitor and Product Directory, and the Colleqt QR-code visitor engagement tool. New for Oi26 (10–12 March 2026) is COAST, a coastal and shallow water exhibition zone and conference track addressing coastal resilience, erosion control, and climate adaptation. Conference programming is organized across the Ocean Futures Theatre, Catch the Next Wave track, Ocean ICT Expo, OCEANSP@CE, Ocean Social, and a Future Tech Hub for ocean-tech start-ups.

The business operates a two-sided B2B model in which visitor registration is free for qualified professionals while revenue is generated from exhibition booth fees, conference sponsorships, and advertising/visibility packages priced on a quote basis. Distribution is direct through the oceanologyinternational.com portal, supplemented by social channels (LinkedIn, X, Facebook, YouTube), email, and the Inside Oi digital platform. Oi24 delivered a 39% uplift in total attendance over the prior cycle, and Oi26 is projected to surpass 8,000 attendees and 500 exhibitors from 80+ countries.
