Tritech expands its industry-standard sonar range with a key renewables device, launching its Gemini SeaTec Mammal Detection System at the All-Energy show in Aberdeen, UK. Gemini SeaTec is a mammal detection system which provides a valuable tool in the detection of marine life around subsea turbines. Tritech’s subsea sonars have been deployed on marine current structures since 2008 when the company made its first step into the offshore renewables sector. Tritech has now developed its real-time multibeam imaging sonar technology for this market.
