Chelsea Technologies
Designs and manufactures environmental and oceanographic monitoring instruments, including sensors used for water quality and marine research.
Chelsea Technologies designs and manufactures environmental monitoring sensors and systems for oceans and other aquatic environments, with a focus on measuring water-related parameters accurately and reliably. The company works across ocean technology, marine science, water quality monitoring, aquaculture, maritime applications, and ocean science, framing its business around making oceans, rivers, and lakes safer and cleaner. Customers use its products to survey aquatic systems, support oceanographic research, monitor pollution and contaminants, and meet regulatory requirements in ballast water management and exhaust gas wash water monitoring. The company addresses industrial and scientific uses beyond open-water monitoring, including measuring primary productivity in phytoplankton, supporting algae production, and enabling autonomous or in-situ measurement from uncrewed systems, autonomous underwater vehicles, gliders, and research vessels. A distinctive part of the business comes from single turnover active fluorometry, optical sensing, and other specialized measurement technologies that deliver highly sensitive, accurate, and reliable results. Chelsea Technologies acts as a systems integrator, adapting underwater technology to specific operational challenges and delivering compact, portable, and autonomous instruments that reduce training needs, operational risk, and the need for laboratory testing. Its products serve both compliance and research needs, from rapid ballast water compliance monitoring to deep-sea profiling and high-biomass phytoplankton assessment. The company forms part of Kraken Robotics, with a broader goal of transforming subsea intelligence, while it keeps a strong environmental monitoring orientation.
