The quality and thus reliability of GRP (Glass-fibre Reinforced Plastic ) pipe systems is based on their design, production, assembly and maintenance. Therefore, end users, manufacturers, contractors, consultancies and other organizations need to ensure relevant competences of personnel during all stages, but especially related to connecting all pipes and other parts into one big GRP pipe system.
DNV GL has, in close cooperation with renowned stakeholders, set competence profiles for professionals working on GRP pipe systems. The certification of the professional competence requirements are in accordance with the ISO 14692, as determined by the DNV GL Certification Committee and incorporated in the end terms. The DNV GL Certification Committee for GRP accommodates the major global end users, manufacturers, contractors and consultants for GRP pipes in developing and maintaining globally acceptable person’s competence standards and pragmatic but strict certification rules for the currently established competence profiles for field specialist in GRP pipe systems:
A Bonder is a skilled worker, specialized in jointing GRP pipes, who’s competences are certified related to one or more different types of joints (e.g. laminated joints , adhesive joints, threaded joints, “O”- rings, locking keys etc.)
A spool builder is certified bonder and additionally certified for assembling the GRP spools and fabricate GRP (mitered) Tee’s and mitered Elbows.
A Pipe fitter is certified to lay out, assemble, fabricate, maintain and repair piping systems.
A certified supervisor monitors and takes responsibility for the execution of the work done by the bonders, spool builders and pipe fitters.
The certified inspector independently monitors the installation of the GRP piping systems. He controls and verifies that bonders, spool builders, pipe fitters, supervisors and other personnel have performed in compliance with the job specs.
Overall certification process
During the examination phase, a certification candidate will have to demonstrate his/her knowledge, skills and performance in a theoretical and practical exam. The exam pieces will be tested according specific DNV-criteria.
DNV GL enforces and monitors the quality and independency of all by DNV licensed examination organizations and authorized examiners. The examinations shall be supervised by a DNV GL authorized examiner whilst using control equipment according to the DNV GL specifications. During the theoretical and practical exams, the DNV GL examination regulations are applicable.
Examination and test facilities
DNV GL has licensed local independent examination organizations to organize certification exams and test and has authorized local examiners to supervise these examinations and tests. Although the exams and tests are strictly independent from any training institute, they can be efficiently organized and scheduled in cooperation with the local training institutes.
All exam and test results will be assessed by DNV GL per candidate preceding the certification decision by the Manager of Certification of Persons of DNV GL. When a positive certification decision is taken, a DNV GL Competence Certificate will be issued to the certificate holder.
DNV GL Certificate of Competence
All certificates of competence for GRP field specialists have a validity period of two year. Each six months, both the certificate holders and the employer/ contractor shall validate the work experience of the certificate holder within his certification range. At the end of the two years validity period, the certificate holder has to take and pass the recertification exam, conditions related to the initial exam.
