Our purpose is to apply engineering excellence and innovation to enable a safer, more sustainable world.


Covelya Group companies operate in a wide range of sectors within the energy, science, defence and commercial markets. We develop, manufacture, sell and support instruments, systems and solutions worldwide.

For over 50 years the companies within the group have been supporting the exploration of the world’s oceans and waters. Our innovative products, technologies and solutions are used in a vast array of scenarios which continue to grow as the world awakens to the resources available from its waters. Our companies are also applying those same technologies to meet new challenges in environmental applications and life sciences, part of our commitment to work towards a safe and sustainable future for all our stakeholders.

The group has a global footprint with facilities and resellers strategically located to ensure the group companies can provide local support to customers and users.

We foster synergistic partnerships between the operating companies to exploit technologies, products and knowledge to grow organically and explore new market sectors together. This is coupled with targeted acquisition and innovation investments.

Always on the lookout for new technologies and business models, we ensure that investments are made to enable the group companies to continue offering market leading solutions to our customers’ challenges.

Compliance is central to all our operations which are conducted in safe and ethical ways with metrics being used to monitor performance across all group companies.

Covelya Group enables the autonomy, independence and individual identities of each of its operating companies whilst providing core skills, experience, resources and worldwide facilities to unlock growth in each.

Our Strategy

Sustainable long-term growth and profitability shared between shareholders and employees. Utilising the group’s global infrastructure as a nucleus for growth.

Essence: Growing our companies via organic internal investment in developing new products and services, and by targeted acquisitions.

Fuse: Combining existing synergistic technologies and products within the partnership of companies using the group’s infrastructure, knowledge and resources.

Edge: Acknowledging the rapid rate of technological change and the limit to internal innovation, we are exploring, developing and investing in disruptive technologies and business models.
