The program recognises that from time to time infrequent, short term visitors are required to go offshore. Personnel who spend less than five consecutive nights on an offshore facility and undertake less than six visits offshore within a 12-month period are not required to hold a CSTP card. Typically these are “visitors” for whom a HUET exemption has also been made.

Offshore construction workforces on construction vessels are currently exempt from having to hold CSTP cards. Marine crew are also currently excluded unless they are directly involved in activities relating to drilling or operations on a production facility.

Some companies require exempt occupations to hold CSTP or have more stringent exemption criteria.
