Sequoia and Aquatec Forge Strategic Partnership on Advanced Sediment Measurement Instruments
[Basingstoke, UK / Bellevue, WA] – Two leaders in oceanographic instrumentation, Sequoia Scientific, Inc. and Aquatec Group Limited, today announced a strategic licensing agreement that secures the future of the widely used LISST-ABS and LISST-AOBS sensors.
Through this agreement, Aquatec will manufacture, supply, and support the instruments via its new specialist subsidiary, TECPRIME Technology Limited. The sensors will be reintroduced to the market as AQUAscat ABS and AQUAscat AOBS, continuing their essential role in measuring suspended sediment and supporting research, environmental monitoring, and offshore operations.
“This partnership underscores the complementary strengths of Sequoia and Aquatec,” said Ole Aarup Mikkelsen, President & CEO of Sequoia Scientific, Inc. “Sequoia continues to focus on its growing portfolio of optical particle measurement technologies, while Aquatec, with its heritage in acoustics, is uniquely equipped to carry forward the LISST-ABS and LISST-AOBS. Together, we are ensuring these technologies remain accessible and supported.”
Andy Smerdon, Chairman of Aquatec Group Limited and TECPRIME Technology Limited, added: “Aquatec and TECPRIME are honoured to collaborate with Sequoia on this important transition. For more than three decades, Aquatec has developed acoustic instruments to study sediment transport in natural waters. This agreement strengthens our market offering, ensures customers retain access to trusted tools, and enables us to innovate further in the years ahead.”
The agreement is effective immediately, with Aquatec/TECPRIME handling all future enquiries, sales, and service requests, while Sequoia continues to honour warranty claims for previously sold units.
