MODU license

Can someone explain the logic behind needing to test for Barge Supervisor, but not needing to test for BCO, or OIM as an Unlimited Master? Especially when there are 5 day courses that take the place of testing for each - all one shot. So, you are essentially good for 2 out of 3…just wondering what the divide is, as far as true competency, or is this just another regulation gap?

Depends on how they feel the day they receive your application. I never tested for BCO or BS, just sent in my modu stability and my sea time letters for each. Working on a drillship, neither BCO or BS is required for any of the officers though.
