Is anyone familiar with the acoustic ESDV leak testing methods and know of any recommended / best practice available? I have heard that this could be used as alternatives to the normal leak testing process that requires full depressurization of the pipeline.

Gents,
We have subsea valves that have not been functioned for a while.
As Left: Filled with MEG at ambient
Flowing pressure: 120 barg
Max DP: 120 barg
Content found initially: Hydrate
Valve condition: clear evidence of the valve passing.
The line now is clean and clear of hydrates, however...
Gents,
I am currently looking at the possibility of replacing our WI PL with something completely different. This will be a big project and I am thinking of going for a plastic lined pipeline system
Is there any integrity issues that anyone can think of that should be considered for WI...
Gents,
Does anyone have historical knowledge of these systems and the normal cost for refurbishment?
I am looking to find out what's wrong with one of the SCMs' we have in our warehouse and I want to know what the average cost of a "fault finding" exercise on a typical SCM is?
And is it...
Gents,
Morning, I am currently looking into inspecting / examining a few of our gaskets in oil and gas environment.
Does anyone know of best practice techniques for the inspection of gaskets?
All I can really think of is visual inspection technique but this will mean inspection thousands due...
I am currently looking into how I can tackle the halite issues we are experiencing with our wells. A lot of them have salt build up just before the SSSV.
We've been trying water washing for a while and that used to work. Now it seems like it is having no effect. We operate at relatively low...
We are having salt build up in the manifold coming from some of our wells causing pressure build up in the wells.
What we do to get rid of the salt is water washing the manifold. My question is, does anyone know of any method of preventing the build up in the first place?
Secondly, we noticed...
Ok, I asked for the first post on this topic to be deleted because for some reason some people took it too personal... Hmmm I wonder why!
Anyways
What's people's opinion on this topic? . Differences between manned and unmanned platform? pluses and minuses.

Hi,
I dont have a task in this but it was something i overhead. I am quite interested in how people deal with the integrity of their bolted joints to prevent hydrocarbon releases/leakages etc.
Please do drop more information or knowledge you have on this subject they will all be taken in and...
Hi guys just a quick question on the inspection of steam turbine valves.
Does anyone have advice on the inspection periodicity for steam turbine HP and IP stop and control valves?
The other question is with regards to life time. When should this valves be changed and under what criteria...
Hi guys,
We have set of anti-icing duct that are failing where the tube is welded onto the manifold.
The system consist of LP steam at about 4bar fed into the anti-icing system at about 128degC
a bundle consist of a bottom manifold where the steam enters and 3 top manifolds.
The bundle is...
Hi,
I have a few questions,
1. what sort of flexible "tube to tube" fitting can be used and will with stand 140degC steam at about 3barg
tube spec => out dia 25mm, wt 1mm
2. what sort of fittings are there (apart from welding & swage joints) for fitting a tube to it's manifold operating with...
Can you please let me know of different designs of anti-icing systems that can be used on different powerstations?
Please do drop more information or knowledge you have on this subject they will all be taken in and appreciated.

There's known issues about pitting corrosion occuring on our anti-icing tubes on the air intake heat exchanger units fitted on our gas turbines. These operates at above 420degC.
Before i kick off this into a big project in replacing all our tubes with materials with better Pitting Resistance...
Hi,
Can someone help me with this? I am trying to calculate minimum wall thickness for pipes according to ASME B31.1 standards,
t (min) = PD/2(SE+PY) + A
t(min)= Minimum wall thickness required (in)
t(corr) = Mechanical, erosion, or corrosion allowance (in), typically 0.05 in. = A
P = Design...
I am currently loking at increasing the ramp rate of a Gas Turbine on a CCGT system, and have a temperature gradient limit.
Can people please just give me what sort of concerns / advice / look outs / issues I should be on the look for as I am not experienced at this.
the only concern I can...
