Training & Site Support

At CSNRI, we pride ourselves on the knowledge and experience of our staff. Our qualified, professional staff delivers field supervision/support and quality control (QC) services as well as a full suite of verification and oversight programs in any installation environment anywhere in the world.

If you want an expert to verify that a repair is being carried out properly, we provide onsite personnel to supervise field work to build confidence in executing composite repairs. Our team monitors the entire repair process to ensure materials are applied correctly for a reliable repair every time.

For installers who want to have a repair verified by a third party prior to commissioning, a CSNRI expert can inspect the work to ensure our products have been installed as intended.

If you need assurance about a repair that has been in service for a while and is approaching its intended repair life, our team can inspect the repair and determine if it is safe or let you know what should be done to enable continued safe operation.

Custom Composite Testing Services

CSNRI places a high priority on R&D activities, and we have some of the best scientists and engineers in our industry constantly working to develop new products and repair solutions, including the capability of doing full in-house ASME PCC-2 certification and testing.  In addition, we also host a fully outfitted testing facility allowing us to perform full-scale testing programs on installed solutions to further validate effectiveness and feed our continuous improvement goals.

With custom-built testing equipment, we can perform testing on pipe diameters anywhere from ¾” up to 48” in full-scale cyclic pressure and burst testing with our custom-built pump system. Our laboratories are fully functional to perform many ASTM tests including tensile, compression, environmental effects, abrasion, adhesion, and many other coupon-level tests.  We have also developed custom testing plans to accommodate special requests such as vibration and cathodic protection evaluations.

Some of our previous testing programs have included:

  • Cyclic pressure testing of 12” OD dent repairs up to 250,000 cycles
  • Cyclic and burst testing of 36” x 12” nozzle repairs
  • Subsea testing replicating deep sea conditions on composite repairs
  • Full burst pressure testing on out-of-service pipeline sections supplied by owners/operators for evaluation of repairs made in field from 16” up to 30” diameters

UK Services

CSNRI Europe’s teams of highly trained leak repair and composite installation technicians are based at our Aberdeen Offshore local office and our Manchester HQ. Coupled with our wide range of qualified composite solutions, CSNRI also provides full turnkey pipeline and vessel repair services to oil and gas companies in the UK.

CSNRI understands our clients’ needs us to respond to urgent situations and we have a proven history of responding to requests 24/7. They may arrive at 9am on a Monday morning or 10pm on a Sunday evening, irrelevant of time, our teams understand the need to do whatever is needed to meet Heli check in deadlines or supply boat departures.

CSNRI staff are trained leak seal technicians who hold full competency certs for installation of all composite systems. We recognize that even when a system can be shut down or isolated there is often a residual leak of fluid. Often if the line is production or safety critical, such as a deluge line, an isolation is not possible. CSNRI has developed several live leak sealing methods including our Composite injection leak seal system to arrest leaks and allow installation of an ECR (Engineered Composite Repair).
