FAQ
Q: What types of inspection services does STR provide?
STR specialises in Flooded Member Detection (FMD), the industry’s method of choice for identifying water ingress in subsea structural members. We deliver this through our SeaGamma and SeaSonic systems, supported by STR’s cathodic protection monitoring (SeaCP) and a wide range of subsea cameras for visual inspection.
Q: Which industries benefit most from STR’s inspection services?
The majority of FMD inspections are carried out within the oil & gas sector, where operators rely on accurate data to maintain subsea assets. Our systems are also applied to renewable subsea infrastructure, supporting the safe installation, maintenance and eventual decommissioning of offshore wind and other energy projects.
Q: How do STR’s inspection services support different project stages?
Our inspection solutions cover the full project lifecycle, from as-built verification after installation, through routine inspection, repair and maintenance (IRM) operations and into decommissioning. Each stage is supported by proven FMD systems, integrated technologies and clear reporting to help clients meet compliance requirements.
Q: What makes STR’s FMD inspection unique in the market?
STR is the only provider offering Gamma FMD as a service, a recognised industry standard. When combined with our acoustic SeaSonic FMD, SeaCP and visual inspection systems, we deliver a comprehensive non-destructive testing (NDT) package that few competitors can match.
Q: How quickly can STR mobilise inspection equipment and teams?
With SeaGamma FMD systems held in the UK, Norway, Australia and Dubai, and supported globally by our specialist engineers, STR can mobilise at short notice, often within a week. Close collaboration with client project teams ensures equipment and personnel are ready when needed.
Q: What are the main benefits of working with STR for inspection?
Clients benefit from faster inspections that reduce vessel costs, accurate results that meet compliance standards and integrated systems designed for ease of deployment. Combined with our in-house software and RPS-trained engineers, STR provides a reliable, end-to-end inspection service that keeps projects efficient and compliant.
