The UJC does not grant jointing concessions for deviations from the jointing specifications.

Any deviations from the jointing specifications are wholly the responsibility of the company providing the jointing service which includes the individual UJC member companies ASN, Global Marine, KCS and SubCom. Care should be taken when granting and issuing concessions to ensure that the safety, strength, service life, integrity & function of the joint or coupling are unaffected for its intended purpose.

Deviations from the specifications covered by concessions should be unique events granted for the operational and the system requirements and limited to each joint construction, on a case by case basis. The UJC welcomes feedback from such concessions where deviations can be seen to be of a re-occurring nature so that investigation and process improvements can be facilitated.
