Growing – We like to grow and take on a challenge, but it is not all about size and performance, it’s about continuous improvement whilst maintaining our core values and ethics, and we want our staff to have some fun achieving this.

Sustainable – We have been going for over 50 years, and we plan to be going at least another 50. To do this we are ensuring we cut our footprint accordingly and help our customers cut theirs where we can.

Our History

Covelya Group Limited was formed in April 2020.

The founding company, Sonardyne International Limited was formed in 1971 by John Partridge who had a vision to make operations beneath the waves safer and more efficient. Sonardyne remains at the heart of Covelya as our largest operating company. We are proud of the origins of our company and invite you to read more about these roots on the Sonardyne website.

Wavefront Systems Limited joined Sonardyne in 2008 to exploit an opportunity that both companies saw around the development of imaging sonar systems. This was the start of our strong preference for working across group companies to encourage the joint development of products, technologies and markets.



Chelsea Technologies Limited was acquired in October 2018 to increase the group offering through access to new technologies within and beyond Sonardyne’s traditional markets. Chelsea’s strengths within environmental monitoring technology enabled diversification and new opportunities for the group.

EIVA a/s was welcomed into the group in May 2019. Bringing strength and depth across software, equipment and services across subsea markets it was clear that there would be many opportunities for integration and collaboration.



Voyis Imaging Inc was acquired in January 2020. It too adds diversity with its focus on underwater laser scanners and imaging payloads and its products have proved to be compatible with existing and developing projects across the group.

The combinations of these acquisitions increased the size of our global team to over 400 people and enhanced our global reach.
