After being in the rov game for over 30 + years I find the whole thing a bit silly also dont forget this is not a one off thing but you must re do it every 3 years .
I feel more like a Cow with a very large bucket under him being milked for every drop of milk they can get .
After having a chat with Sonsub in Singapore it seems that most of there guys are doing the MTCS HV distance learning package. This costs £135.00 per person (plus VAT).
This course can be taken offshore and the assessment is submitted to MTCS Ltd. on line. There is a practical element that should be taken offshore/in base and requires you to demonstrate that you are aware of isolation procedures and safe working practices for ROV HV systems.
Cheers all and Bring Your Own Bucket !
