OCEANS 2023 Limerick – the first OCEANS conference in Ireland

Isela Ibrahimovic, Coordination Chair, OCEANS Limerick 2023


This was the first time the OCEANS conference came to the “Emerald Isle” and the first entirely in-person conference after COVID-19.
The event was held at the University of Limerick Green Campus, a beautiful parkland with the River Shannon as its unifying focal point. The local hosting was led by the Centre for Robotics and Intelligent Systems (CRIS), the only research Centre in Ireland in underwater robotics, with the support of the key partner for the event, Marine Institute, a leading Irish marine research institution.

OCEANS’23 Limerick attracted close to 700 delegates across all the registration categories.

Delegates gathered from around the world for four days (5 to 8 June) to highlight relevant topics and current trends while creating a community of learners and influencers who consistently advance research, practices, and policies under the “Blue Ocean Planet Earth” theme. The conference theme was broader, enabling the committee to offer a diverse technical programme, but with a focus on the relevant local and geographical interest topics.


Behind the “scene,” there is always a great team of people making OCEANS events possible. We give special thanks to our local committee members who worked very hard to ensure a successful conference.

OCEANS 2023 programme

To reflect and underpin the conference theme, a set of local Limerick topics was chosen to be the conference’s centerpiece. A series of plenary and keynote talks were presented to highlight them. These local topics include Offshore wind energy, Ship decarbonisation, Drones in marine applications, Cultural heritage and underwater archaeology, Artificial Intelligence in Ocean Science & Technology, Analytics and Sensing: A new age of dynamic observations, Renewable Energy from the Sea (Wave, Tidal, OTEC, Salinity gradient…), Sustainable Blue Economy, Maritime Vehicle Navigation, Deep Sea Mining, deep sea exploration and parallels to outer space.

In addition, all the traditional OCEANS conference technical tracks ensured that the conference in Limerick retained and maintained its standard structure.

Plenaries and panels

Technical sessions

Ten parallel trucks were run during each conference day, covering a total of 428 presentations, including the general poster session and student poster competition. There were ten special sessions. Traditionally the highest number of papers were presented under the “Autonomous underwater vehicle” topic.  The programme was exciting, comprehensive and well-balanced.


As an add-on to the general programme, the first day of the conference was dedicated to the tutorials. Ten tutorials and one workshop were held on 5 June, with an attendance of over 220 delegates across all sessions. The tutorial fee was included in all full registrations, which we believe significantly increased the number of tutorial attendees.

The covered topics were the following:

  • Detection of Underwater Acoustic Signals – theory and techniques
  • SAR Remote Sensing of the Ocean Surface
  • Building Marine Cyber Resilience using Cybersecurity Standards,
  • Governance, Risk and Control
  • Transceiver Design for Underwater Acoustic communications
  • Introduction to LSTS Toolchain: Bridging interoperability challenges
  • Data Management: A Short Hands-On How-To
  • MARUS – Unity Based Simulator for Marine Robotic
  • Underwater Optical Sensing and Real-time Data Transmission: in-situ measurement of marine particles and other organisms
  • Navigating Estuary and Port Applications of Small Autonomous Surface Vessels: Tips, Pitfalls, and Rules of the Road

Student Poster Competition

One hundred and fifty-six abstracts were submitted for the student poster competition, and based on the threshold score, around 121 were selected for 2nd stage of review (SPC). Following this 2nd review stage, 14 posters were selected for the SPC final.
The SPC jury selected the following winners:

  • First Prize: Amelia Ritger, University of California,
  • Second Prize: Jared McFadden, Florida Atlantic University
  • Third Prize: Patrick McGuire, Woods Hole Oceanographic Institution

The prize winners’ details were announced during lunchtime at the Innovation Hub theatre on the closing day.
You can read the SPC report, winning article and articles from top two winners in this Beacon issue, too.


The exhibition was held in two connected marquees near the conference hall. This made it still possible to bring the technical sessions and the exhibits close together and to have an increased footfall in the exhibition space. The existing crisis inevitably led to reduced exhibitors registering for OCEANS Limerick, and we eventually had 46 booths available. Hard work by the LOC resulted in 42 Institutions (Companies, Research Institutes, Professional Bodies, Societies, and Media Organizations) represented across 46 booths (triple, single, shared or small booths). The exhibitor track was run in the Innovation Theater, and the slots were given to all exhibitors to address the audience and present their products, research or institutions.

Social programme

As in all OCEANS conferences, the social program is essential in enabling delegates to relax and interact in an informal atmosphere. The OCEANS ’23 Limerick team organised a schedule of events designed to give delegates the full flavour of Irish culture.

  1. Student mixer

The Student Mixer was organised for registered students and student poster competitors in a casual setting for networking. Young Professionals and leaders from the Oceanic Engineering Society and Marine Technology Society attended to orient the students to the OCEANS conference and guide how to get the most out of the event. Stables Club, University of Limerick, has a great atmosphere with DJ and BBQ.

  1. Icebreaking event

Another successful networking event was held on Monday afternoon (5 June), the Icebreaking Reception in the University Concert Hall Atrium—a great way to end the first day with relaxing music, good food and drinks.

  1. Exhibition reception

Tuesday afternoon was reserved for networking with exhibitors, starting with the Canadian National Pavilion event, followed by the exhibitors’ reception. Drinks and nibbles were offered to enable exhibitors and attendees to relax in an informal environment.

  1. Gala dinner

The conference banquet was held at the Strand Hotel and was followed by a visit to King John’s Castle for an exciting medieval experience. The gala program included traditional Irish music and dance, and 480 delegates could also enjoy the performances of Prof. Daniel Toal, whose fiddle melodies give the atmosphere an extra spark of Irish hospitality.
