shut down production for another week.



There’s a reason the best welders are often offshore.

Shuting down production is a huge decision to do a weld, they will come up with all sorts of schemes to avoid actually shutting down. Bolted schemes, composite wraps, Quick flange etc. And god forbid for an extra week, there are rigs in the North Sea now that if shutdown for a week wouldnt be restarted as they are not viable. When your the one accountable to hit the stop button, it pays to be sure there are not going to be any extra weeks unplanned outage, hence why so much sandbagging goes into the preparation.

This thread makes out that the streets of Aberdeen are still paved with gold, if you can wear a Kromer backwards, the days of hundreds of welders and pipefighters building rigs in situ are long gone. Its all now built and part commissioned before hook up.

As for the best welders, there is one on every installation called BINS, usually a crane driver with a similar nick name too.

here is a typical deck section big gap been out in the salty atmosphere for weeks
lots of cleaning before starting and min 150c pre heat sometimes heating bands too
the platers usualy come away with a good welder would get that
our reply is well you better find one View attachment 150096

GSFCAW, loads of preheat and ceramic backing tiles...

unfortunately no procedure for it
just good old Filarc 88s
we need roofing tiles for some preps
but as they say chaos is cash

Typical rough @r$ed platers, if they spent an extra hour on fit up, you'd save a shift or two on the welding!

I’ve qualified a procedure using 56S to fill an 15mm gap in 4G position.

As you say zep, buttering runs, grind a root prep, roughly 3mm gap, root as per normal.

Keep knocking it back, When I was in Cosco shipyard in China they gave the welders some very poor fit-ups, if your not happy and it’s out of spec knock it back or get the foreman to knock it back, they soon brought better plater’s in, why would anyone weld something that the root gaps as wide as the plate thickness, even if the procedure allows this it’s a waste of time and consumables, The Chinese UT techs got very nervous when you were looking over their shoulder!

The old saying was 'if you can step over it you can fill it with weld' not entirely sure that the inspectors would be quite as keen on that these days...
