Got into a debate with a mate on the ship I’m on, and I wanted y’all’s take:
The topic was a two for one. Are DP vessels considered RAM while they are actively working inside the 500M zone around platforms? And if a vessel was on DP while in restricted visibility, which sound signal would they use one for a vessel at anchor, underway making way, or underway not making way?
I said that they would be considered RAM because due to the nature of work being alongside a platform they are restricted in their ability to maneuver to avoid collision. My opinion for the second question was that we should sound a signal for a vessel at anchor to let other vessels know that we are stationary and not moving.
Any and all thoughts are welcome!
