Topside and Underwater Inspection

CSWIP provides a range of certifications for those working both underwater, topside and offshore. These certifications provide industry with the assurance that their inspectors are competent in both underwater inspection and non-destructive testing. It is also possible to add specialised tests depending on the particular needs of the candidate, employer or client, such as concrete inspection and A-Scan endorsement.

The CSWIP Underwater Inspector Scheme is divided into two certifications enabling entry, and a means of progression, from basic knowledge and skills to greater responsibilities in inspection and testing. It is then possible to progress further and become more specialised as a CSWIP ROV Inspector or CSWIP Underwater Inspection Controller.
