Systems and Qualification Testing

2H conducts qualification testing of components and fabrication methods typically as part of our activity as a riser integration specialist.

We have helped to define, plan and perform successful qualification testing on a variety of components including taper stress joints, buoyancy modules, mechanical connections, welded connections and the associated inspection systems, tensioning systems, monitoring systems and managed pressure drilling riser components. Our experience extends from high strength metallic materials to non-metallic materials used in seals, coatings and monitoring.

Our qualification testing capability is focused around two key areas of expertise:  that of industry codes and standards such as API, ISO, ASTM, DNV, ABS and NACE, etc, and our knowledge of testing equipment such as valves, fittings, HPU’s, as well as data acquisition systems and methods of data interpretation. This combination of skills enables the development and implementation of detailed testing protocols that have assisted our clients to succeed in their testing programs for both evolution of existing technology and the development of novel technology,
