Recent RNS excerpts:
“More recently GyroMetric has moved into monitoring and protecting wind turbines, having recently completed HIGHLY SUCCESSFUL trials using the world's newest and most powerful offshore wind turbine drive train test facility at the Offshore Renewable Energy (ORE) Catapult at Blyth.”
“Monitoring the condition of rotating shaft mechanisms has traditionally been carried out using vibration sensors. Such sensors measure the frequencies and amplitudes of vibration. The GyroMetric approach is to measure accurately the ACTUAL displacements and the frequencies...”
The competition doesn’t exist, in the truest sense of the term, given the tech is UNIQUE. So existing Condition Monitoring Services (CMS) measure vibrations (using accelerometers, sensors etc), thermal, acoustic etc and extrapolate this to measuring the defects within the drive train system. Examples include Gram-Juhls.

From what I read, these guys have been around 21 yrs and have cornered approximately 80-90% of the offshore wind turbine condition monitoring (TCM) share worldwide, being fitted within Siemens-Gamesa (merged wind businesses in 2017) turbines etc.
Gyrometric measures ACTUAL displacement. It does this using three sensors, along two axes, and the first generation did it using DIGITAL sensors. They applied for a new patent with the U.K. IPO in March 2018, towards an improved encoder, that measures displacement using ANALOGUE sensors. This should further improve the accuracy of a technology that is already far ahead of peers, imho.

White paper on the research published few years ago. The gyrometric team is essentially pedigree academics with serial entrepreneurs, they have been working on this tech for over 20 years. They have already commercialised it in the Marine market. Wind turbines need “marinised” kit which can withstand harsh environs. It should get very interesting if any turbine manufacturer considers incorporating this. The two cos supplying off shore turbines in the U.K. are MHI Vestas and Siemens-Gamesa.
Recent trading update RNS clearly signals TWO major manufacturers involved: “These trials have led to serious interest from two major turbine manufactures, one of which has signed a contract to test the IME system on their own equipment in 2019 and a further trial is scheduled at ORE for the other. In 2019 further material progress and COMMERCIAL developments are expected in relation to both these opportunities.” Imho this is GE and either Siemens or MHI Vestas.
Plus “strong” enquiries from numerous other manufacturers (ALL three major chinese manufacturers, and let’s face it, if you are ignoring China as a market, you are missing a big chunk going forwards). Intellectual property developed over decades of research, ie proprietary software and algorithms, towards interpreting the IME data.
