Bilfinger Salamis UK currently has in excess of 250 multi-disciplined, competence-assured, NDT Technicians delivering conventional, advanced and specialist NDT, utilising the latest equipment and techniques. Over 90% of our technicians are rope access qualified.

The company is head-quartered in Aberdeen and supported by a dedicated, purpose-built warehousing, testing and validation facility offering 600 sq.m office space, 2,000 sq.m of warehouse and 9,000 sq.m of yard space. This central logistics hub is supported by three regional hubs in Great Yarmouth, Esbjerg (Denmark) and Groningen (Netherlands).

Bilfinger has established itself at the cutting edge of NDT through continuous investment in specialised equipment and the delivery of industry- and client-specific training programmes.  Bilfinger also invests considerable time and resources in the validation of emerging NDT techniques as is evidenced by our successful collaborations with HOIS and OGTC.

Our bespoke training and competency assurance programmes ensure that our technicians are fully trained and certificated, and that they exhibit the correct behavioural and safety leadership at all times: we never compromise on integrity or safety.

Advanced NDT Validations

We are continuously developing and evaluating new tools and technology. By focusing on the practical applications of new technology we are better able to qualify the real, tangible benefits of new developments and to deliver best-fit solutions.

Bilfinger Salamis UK are participating members of the Harwell Offshore Inspection Research and Development Service (HOIS), which is a joint industry initiative involved in developing and improving products, techniques, and procedures. The HOIS programme includes projects within a number of broad theme areas. These include non-intrusive inspection (NII), inspection of inaccessible components, performance evaluation and probability of detection (POD) assessment and modelling. 

This is achieved by:

  • Developing improved procedures and recommended practices
  • Performing independent evaluation trials to assess techniques and understand benefits and limitations
  • Collaborative development of inspection techniques and inspection technology

By working in close partnership with the leading NDT solutions manufacturers, advanced NDT providers and taking an active lead in collaborative research through trade organisations such as HOIS and the OGTC, we can ensure we never compromise on our commitment to provide best-fit solutions, thereby reducing uncertainty, improving confidence and ultimately extending asset life and reducing costs.
