Hello offshore structure engineers,
I am preparing inspection report for an offshore structure. Can you please help me in providing the technical name for the items marked in the attached document.
Thanks in advance.

1 "SW",or "NE" (or whatever direction, or use an "A-1", "B-2" designation) Jacket Leg, Splash Zone,
2 Not sure what that is. May be,
"Stub" "SW", or "A-2" Jacket Leg, Splash Zone
3 "SW", or "A-2" Lower Deck Column, Elevation +XX.XX
4 "SW", or "B-2" Stabbing Point Flange, , Elevation +XX.XX
5 "SW", or "B-2" Lower to Upper Deck Column Joint, Elevation +XX.XX
6 Not sure what that is. May be
Jib Crane Mast Extension Joint
RE: Offshore structure parts
6 - Some sort of collar? - difficult to see.

RE: Offshore structure parts
All the 4 legs has item no 2. I too think it has been something left after installation. The legs seem to be filled with concrete.
I have posted the picture of item no 6. It looks like some rubber sleeve around the support column on the loading arm.

RE: Offshore structure parts
No 6 is a rubber collar that should be higher up - you can see the gap further up. It is designed so that when the crane jib moves around, it cushions the main support leg from damage as the half shell hits it. But it's fallen down.
So its a rubber protection sleeve.
But it needs to be fixed back in place.
That second photo 3580 shows it much better. The crane jib can rotate 180 degrees, but the position stop is supposed to hit the protection sleeve. on the other photo you can see the metal clamp on the bottom is broken.

And what was that vertical post in the previous document I had attached?

RE: Offshore structure parts
Do you know what is the purpose of this vertical post? This vertical post is far away from the flare.

RE: Offshore structure parts
Thank you again for your information regarding the flare and pilots.
RE: Offshore structure parts
I think those three little prongs are measuring heat in case the vent ignites or measuring it to make sure it hasn't gone out. You should find them on a P&ID of the vent/flare system which should tell you what these are supposed to be.
The little line looks like a small diameter cold vent to me.
The long pipe thing looks like a lightening rod to me as well, but I'm glad I will never climb up such a thin vertical pipe....
But mr 44 could be also dead right about the flare stuff.

This thing is off a 45 degree elbow, then cut at 45 degrees to have vertical face. Looks like a vent stack to me.

RE: Offshore structure parts
I agree with LittleInch regarding this. This is a vent as there is no black soot around the pipes which gets deposited on the external surface of pipes due to flaring. The small pipe was supposed to have a hat like structure on top which has corroded away which is not required in a pilot burner.
I also think the vertical post is for lightening arrestor.

That one the end of the pipe is horizontal

RE: Offshore structure parts
Not sure that tip angle actually matters a whole lot.
Why would it have to be pointing up? Out and away seems better.
Full speed ahead.
RE: Offshore structure parts
But all the ends are 90 degrees to the pipe.
