No, all diving equipment is provided for courses and examinations taken place at TWI facilities.

All CSWIP underwater qualifications are valid for 5 years. The certificates are renewed by attending an examination at an approved TWI centre.

TWI has diving facilities in Middlesbrough in the UK, Chonburi in Thailand and Baku, Azerbaijan – this is where the 3.1U and 3.2U NDT Inspection training and examinations take place. For courses that do not require a diving tank (3.3U ROV Inspector and 3.4U Underwater Inspection Controller) the venues are worldwide.

To renew your certification you will need to successfully complete a renewal examination. A renewal examination can be taken from 6 months prior to the expiry date upon till the ticket expires. We would strongly advise attending refresher training prior to your examination.
