Supply Boat Types

**follow40** · April 14th, 2012, 12:21 PM

Having recently started working on platform supply vessels I frequently hear people talking about different supply boats being called by numbers such as 755's 705's etc.... apparently its got something to do with the design of the hull but I'm still not absolutly sure what they're on about... I've tried searching google for information about this but so far I've failed to come up with any decent info.

Can anyone tell me more about these numbers? And also let me know how many different ones there are and the differences between them.

It sounds like they are talking about length

That's the model number from builders for the vessels over in Europe.
Just an educated guess, but probably like 7th generation and 205ft long or 255ft long.

This mostly a US forum, so i doubt any of us could tell you the difference.

That link goes on about the Rolls-Royce UT 755 series offshore supply vessels.

Nah it wont't stand for 205ft because we use metric over here, gave up on imperial measurements a while back.

Looking at the link, it is amazing how far the dollar goes when getting a new build in Italy. What would $7.5 MM get in the US? A 166 DP1 with maybe some spare change left over?

Wasn't Ulstein designing those boats?

755= 75.5m= 250'
It's my guess, it's just a guess

Here's an interesting piece on the UT 704:

In regards to the Ulstein vessels; 755 is simply a model number. The 755, 755-L are probably the "best selling" PSVs presently being built.
These vessels are the back bone of the global OSV fleet.
Surfing the web I found a couple of interesting articles on the history of UT-704, which in its day was the premire AHTS vessel.
I can't seem to add links to my posts here on GCaptain, but one intersting site is ships and oil dot com which many of you will probably enjoy.

I know some people that have sailed on the 755's built in italy... I guess you can say you get what you pay for as I hear the build quality is not the best, too many design flaws apparently.

In Europe the best supply boats by far are built in Norway. Polish built are not too bad either.

Check out this beast of a boat built in Norway called the Olympic Commander,
