Muiri Carraige Aonair Teoranta

Muiri Carraige Aonair Teoranta (MCAT) is pioneering Ireland’s underwater frontier with the nation’s first purpose‑built research submarines. Operating the A‑EX1 and A‑EX2, MCAT deploys state‑of‑the‑art U‑Boat Worx submersibles – capable of diving to 300 metres, carrying a pilot plus two passengers, and remaining submerged for up to 12 hours – to explore the 90 percent of Irish territory that lies beneath the sea.

The company offers a suite of specialised services to marine‑focused businesses, academic research bodies and government agencies. Its capabilities include high‑resolution 4K video recording, forward‑looking imaging sonar, and long‑duration data collection for environmental monitoring, marine archaeology, and other scientific investigations. All vessels are independently certified, meeting stringent safety standards and rigorous testing from design through delivery.

MCAT welcomes collaboration, positioning its cutting‑edge technology as a platform for partners seeking to understand, protect and sustainably manage Ireland’s hidden marine heritage.
