The three-day event, which runs from April 8-10 at the National Oceanography Centre in Southampton, is open to all visitors for free by registering online at www.oceanbusiness.com.

With more than 350 exhibitors already booked for the sold-out show, this year’s Ocean Business is expected to attract over 5,000 visitors from around the world, offering unrivalled networking opportunities.

The popular Training and Demonstration programme – to be unveiled shortly – is also bigger this year, with 180-plus hours of new technologies demonstrated in the dockside waters, onboard vessels and in the classroom.

The sessions will explore tomorrow’s world today, displaying the latest in autonomous vehicle underwater monitoring, next generation ROVs, ground-breaking advances in AUV technology, and much more.

In the quayside hospitality suites, key industry players, including Teledyne Marine, Nortek and Greensea IQ, alongside ocean tech experts from the Canada Pavilion, will showcase their products and services, all with a focus on fast changing technology.

Meanwhile, inside the expanded exhibition halls, visitors will be able to see pioneering developments across the ocean technology sector and find solutions to shape the future of their business.

Ocean Business 2025 will preview emerging technologies from sector pioneers and game-changing innovators, with the familiar big-name suppliers exhibiting with newer entrants to the industry.

Visitors will be able to see the most up-to-date equipment in action, test drive products to keep them ahead of the competition, and connect with industry leaders in an interactive environment.  

The Ocean Careers programme is back, offering students an opportunity to meet potential employers and gain valuable insights from industry professionals.

Ocean Business 2025 will also stage a two-day, free-to-attend conference – on top of a series of associated, on-site meetings - with leading sector voices addressing critical industry issues.

Additionally, Ocean Business will once again host MARELEC, the world’s only conference dedicated to marine electromagnetics. Building on the success of the 2023 event, delegates will hear from eminent scientists, engineers and academics of advances in the fields of geophysics, geotechnical engineering, oceanography and naval warfare.

Cheri Arvonio, Event Director at show organiser Diversified Communications, said: 'Ocean Business has become a must-attend event for marine industries.

‘As the countdown to Ocean Business 2025 begins, we look forward to welcoming the international ocean business community back to Southampton in April.

‘We are delighted with the response from exhibitors and we have high hopes that this enthusiasm will be matched by registrations as we gear up for our biggest show yet.

‘Ocean Business provides an ideal platform for doing business, forging relationships, hearing industry updates and sharing ideas, and we are confident that this year’s event will turn out to be a memorable occasion for ocean people everywhere.’
