Is it for me?

Completing the CSWIP 3.3U ROV Inspector online course cuts the duration of time required at a TWI Training Centre to a minimum. The online course is delivered in two parts covering theoretical and practical elements leaving you to only attend a TWI Training Centre for the CSWIP examination.

You will be required to complete the CSWIP 3.3U online theory course prior to attending the online practical course.
The practical training will be delivered via Zoom.  Candidates who have completed both theory and practical online courses, and successfully passed the end of course assessment can then attend the CSWIP examination at a TWI Training Centre.

What will I learn?
