Severn Subsea Technologies offers a full range of engineering services from initial concepts through to detailed design, manufacture, test and type approval.

Our engineering team includes mechanical, electrical, electronics and software engineers with many years’ experience of geothermal, seismic and subsea applications.

Since obtaining ISO-9001 registration in 1996, Severn Subsea Technologies has endeavoured to improve on this standard and is actively seeking a DNV recognised status.

The quality system encompasses all working functions of the company from design through manufacturing to testing and delivery. The recent introduction of SolidWorks Enterprise Product Data Management (PDM) helps with the workflow process and documentation control. Through PDM we are able to ensure design traceability via a predefined workflow process that includes design reviews, engineering change notes, checking and approval stages that must be signed off before proceeding to the next phase.

Projects and Products

Severn Subsea Technologies combines bespoke projects with a growing range of readily customizable ‘standard’ tools. Bespoke projects are normally one-off assignments where we are able to offer a suite of services designed to either enhance an existing product or develop a completely new product from a concept design. In both cases our approach is based on establishing a close working relationship with our client, and a willingness to use our knowledge and experience to question design assumptions, to ultimately arrive at a product design that meets and in many cases exceeds client expectations.

Our range of ‘standard’ tools is designed to be readily customizable to meet specific project requirements.  It includes:

• Downhole Camera
• Riser / Pipeline Camera
• Logging Tools
• Sensor Carrier Systems
• HPHT Production Logging Tools
• Hydraulic Intensifiers.

  • HPHT Testing

    Extensive HPHT testing facilities.

  • Manufacture

    Precision engineering using a range of advanced materials.

  • Development

    New technology, ideas and project management.

  • Design

    Specification Production, Mechanical and Electronics Design
