Established in 1991, Tritech International Limited [Tritech] began with the aim of producing an innovative range of subsea products for the offshore oil & gas industry, military and other world-wide subsea markets.

As specialists in the production of high performance acoustic sensors, sonars, video cameras and mechanical tooling equipment we serve professional underwater markets, including; defence, energy, engineering, survey and underwater vehicles.

In recent years, new markets have emerged from within these professional underwater markets, within the energy industry; decommissioning, debris clearance, hydro-electric and renewables and in within the defence industry; law enforcement and Search and Rescue (SAR). Operations in these working environments usually result in low-visibility and in very shallow or very deep water. From our imaging ranges (mechanical and multibeam) to our bathymetric sensors, to hydraulic and mechanical equipment, Tritech are able to support these developing industries.

Today, Tritech remains a respected industry leader in the provision of sensors and tools for ROV/ AUV markets, a reputation achieved from its 21 years of delivering expertise through key industry-standard products such as the Super SeaKing mechanically scanning sonar and the Subsea UK award-winning Gemini 720i real-time multibeam imaging sonar.


Obstacle Avoidance & Target Recognition Sonar. Tritech’s SeaKing sonar is the sonar of choice for many of the world’s ROV fleets. For fast, reliable and complete operational flexibility, all products in the SeaKing family can be run simultaneously on a single ArcNet communications link, using the same processor and display. The Super SeaKing family of products provide all around obstacle avoidance and target search and recognition capability to any underwater vehicle, offering Digital Sonar Technology (DST) and low power consumption (suitable for AUV platforms).

Real-Time Multibeam Imaging Sonar – Gemini. Tritech remains an industry leader in the mechanical scanning sonar market; however as underwater vehicles become more powerful and time constraints become more critical offshore. Gemini’s real-time imaging eliminates the restrictions in low-visibility conditions. In underwater operations Gemini enables rapid visualization, easy interpretation, search and inspection of the underwater environment. Interfacing provides for full integration with users operational/ control software. Current R&D initiatives include the further development of the Gemini range and further multibeam applications as recently showcased at Ocean Business.

RAMS™ is a real-time, field-proven system which detects the presence, integrity and position of mooring lines and risers deployed beneath a FPSO.
