Our engineers have over 100 years of combined experience and industry-proven capability in realising the best solution for our customers.

Hydro Group offers project management support services to customers from initial concept stage through to on-site installation and maintenance.


We offer in-house pressure, optical and electrical testing through our Quality Assurance team. Hydro Group is able to carry out hydraulic, hydrostatic and helium pressure-testing along with SF6 gas testing. Testing is performed with several pressurise, hold and vent cycle combinations for total assurance in multiple operating environments.

Third-party verification on our testing procedures can also be delivered by surveying companies including Lloyd’s Register, Det Norske Veritas and American Bureau of Shipping.

Our optical technicians are trained in optical fibre installation and testing to City & Guilds standard, with specialised engineers trained in multimode optical termination and testing.


We are able to carry out fault-finding and repair recommendations on a variety of electronics, including in customer-supplied connector and cable assemblies. Alternatively, our trained technicians can be made available at your site to carry out testing and repairs.


Hydro Group is also experienced in providing field support for electrical, optical and mechanical termination and moulding requirements. Our competitive technician rates are inclusive of all standard equipment required to carry out the work, with breakdowns for day and overtime rates and all necessary details required for the task at hand.

For more unusual applications, specifically-engineered terminations and mould tools can be created through our engineering department to ensure a trouble-free installation on-site.
