Chelsea Technologies Group (CTG) started life as a spin out from Imperial College. Over the last 50 years, they have developed an reputation as a manufacturer of innovative sensors & systems for the military & civil oceanographic, environmental, acoustics & process control markets. CTG’s sensor technology is being pioneered for a range of applications. It is being used to help submariners understand the oceanographic environment within which they operate, monitor water supplies to guard against chemical attack by terrorists, & monitor oceanic algae & their response to climate change. For the last two years CTG has been working with Liquid Robotics to provide them with a number of UV AquaTracka hydrocarbon sensors for integration into their Wave Gliders®. The UV AquaTracka is the industry standard for hydrocarbon detection, a reputation proven during the Macondo Oil Spill. The UV AquaTracka is so sensitive it can detect aromatic hydrocarbons diluted a thousand billion times in water. CTG is working on a number of other projects including providing sensors to monitor ballast water to prevent the transfer of invasive marine species. They are also producing a new range of sensors to monitor ship exhaust scrubbing systems thus preventing environmental pollution. CTG’s underwater acoustics transducers are being used to study the reactions of fish to sound, evaluating active and passive submarine sonars and as part of a blowout preventer acoustic control and monitoring system.

Products

A team of highly experienced scientists and engineers is engaged in manufacture of a range of oceanographic sensors, sonar systems, acoustic transducers, towed vehicle system and ship’s flow through sensors. CTG is leading the way in Fast Repetition Rate Fluorometer development. The recently launched FastOcean improves the accuracy of primary productivity measurements within diverse natural phytoplankton communities. Applications include primary productivity measurements, coastal monitoring, algal bloom detection, ballast water monitoring & the protection of water supplies. Following on from the successful launch of the Lux range of miniature high performance fluorometers, over 200 units are in the field with users reporting excellent datasets. Applications include in-situ chlorophyll a & algae class studies, dye tracing, particulate studies, hydrocarbon & CDOM monitoring. CTG also has an established range of acoustics transducers including hydrophones, projectors, towed arrays and military sonar test & evaluation systems. CTG has a long history of working with navies and has supplied the Sonar 2115 oceanographic system for a fleet wide installation onboard the Royal Navy’s new Astute class submarines. CTG is also providing post design services for support of the Trafalgar Class Sonar 2081 submarine oceanographic sensor suite. This work includes service, repair & calibration is undertaken at CTG’s UK facility utilizing the NAMAS approved calibration laboratory.
