Severn Subsea Technologies

Severn Subsea Technologies (SST) is a specialist in the fields of subsea, marine renewable energy and downhole engineering. We design and build high reliability systems for harsh high pressure/high temperature (HPHT) environments. Our key technologies include: high integrity pressure protection systems (HIPPS), fluid management and communications systems, HPHT engineering technologies and sealing systems. We offer product development support, from concept design and prototype production, through to major projects requiring extensive research and development.

SST has full ISO 9001 certification and a functional safety management system. SST also has experience in ATEX/IECEx and the company quality system has been certified compliant with 60079-34, enabling us to manufacture ATEX Zone 0 and IECEx intrinsically safe systems.

Severn Subsea Technologies – Research Centre

Within the research facility we have our administration, R&D, design and testing resource, as well as our experienced team of mechanical, electronic and software engineers and technicians who are able to offer a full systems engineering capability.

Severn Subsea Technologies – HIPPS Engineering Centre

The SST HIPPS engineering facility offers a full functional safety management service including a dedicated HIPPS design, assembly and test facility. All HIPPS projects are performed using a standard design methodology ensuring consistency of interpretation of IEC 61508 and IEC 61511. The SST HIPPS facility enables integrated factory acceptance tests bringing together the HIPPS components, customer and certifying body into a single space for validation and testing.
