3000 ITC Master OSV on a vessel with a dual tonnage certificate

I currently hold 3000 ITC Master OSV NC (domestic waters only) as well as 500 GRT Master NC. I just took a new job with a company in Louisiana that operates mostly (maybe only) offshore supply vessels. This might sound like a dumb question, but a situation has arisen between my new personnel manager and myself about my capacity to sail as master or mate on a particular vessel.

The OSV in question has a dual tonnage certificate: 1174 GT (ITC) and 996 GRT. It works coast wise in the Gulf of Mexico doing what all the other OSVs are doing out there. I’ve asked the NMC whether or not I qualified to run as master or mate on that vessel and they said that I could. They also directed me to talk to the USCG Inspection Division in sector New Orleans. I spoke with them as well and they said that the OSV was within my licenses’ capacity.

Does anyone else have an opinion on whether or not I qualify to work in the capacity as master or mate on this vessel I have described? I believe the heart of my personnel manager’s argument is that although I meet the ITC requirements, the vessel was also measured with GRT. So, that is true, nowhere on my license does it say that I can run as master or mate on a vessel less than 1600 GRT, OSV or otherwise. I guess that’s how the disagreement is still in play.

Also, as a side note, how do I change this personnel manger’s mind? What proof other than my license and the paperwork on the vessel can I offer? The situation seems absurd to me, but It wouldn’t be the first time I was wrong in a disagreement. I’m pretty sure this is the first time he has seen a 3000 ITC Master OSV license.

Old thread but for sake of not starting a new one I have a similar problem.

I went from AB to 100 ton master 500 ton/3000ton ITC OSV license. I’ve been working on a 491 ton vessel for a few year and now they are offering me a spot on a new build. The tonnage hasn’t been set but they are saying over 500tons but under 1600 tons and they are putting in for duel tonnage.

Will I be able to run as mate under my 3000 ton ITC in the gulf of Mexico Aboard it?

Why not upgrade to a 1600/3000 license? Then there will be no issues…

I was working with a Master 500/3000 on a 1800 ITC vessel, and he was having no problems.

Boarider- Your good to go as long as it stays under 3000ITC.

But did the vessel in question have dual tonnage or just ITC?

I’ve come to that conclusion after seeing 20 people here get laid-off this week.
I’m on the boat now in the shipyard and we are doing the inclin test next week, I think she’ll fall under 3000ITC.
Thanks for the input, I feel a lot more at ease.

Doesn’t ‘less than 1600 OSV’ come with 3000 ITC?
for example, the national page says less than 1600 GRT OSV and on the int’l page the 3000 GT is used. This would cover the dual tonnage as long as the vessels domestic tonnage isn’t 1600 or over.

I’m not sure if they’ve changed the wording but the OSV only license was for not more than 500 GRT / 3000 GT. Even the large OSV used to read 500 GRT / 6000 GT.

I bet this is something where there will be differences for lots of folks in the last year. I upgraded six months ago, and my national page says ‘master less than 1600 grt osv’ while the stcw says ‘less than 3000 gt OSV.’ For the 500 ton, everything on both sides is simply listed as ‘master less than 500.’

Then they probably changed the wording with the 2014 rulemaking like they did with the 6000 ton but this guy sounds l apparently has the old worded license and I believe the wording on it is still binding even though it should be automatically changed next time he renews.

Previous law did not permit OSVs to be larger than 500 “gross tons.” Gross tons was taken to mean GRT, thus larger OSVs were measured GT only, and the 500 GRT on the endorsement.

For the record, I do renew in March 2016. Should be interesting how they word it.

For three functionally identical,just-issued raises-in-grade that I have first-hand knowledge of, NMC issued different endorsements and restrictions. You would think that, in 2015 and with the available resources (software, programming, database management) it wouldn’t come down to different interpretations between different evaluators … but apparently it does. To the point of this thread, though, my OSV license was issued as 1600/3000.
