Korea Coast Guard, Incheon Metropolitan City, Incheon Tourism Organization and Reed K. Fairs together form the official host and organiser-side contact structure of Korea Ocean Expo. The first two provide maritime-safety and municipal backing, while the latter two handle exhibition operations, venue coordination and market outreach.

For exhibitor, visitor and partnership enquiries, the official website provides a unified public email address and phone number, and the Contact page also lists named project-team members and roles for more specific communication.
