I suggest that as an engineer you need to at least identify what the correct solution is as per LittleInch's advice. The first step would be to discuss with the pump vendors. The impellor may be able to be changed, pump speed (VSD/VVVF), the pump displacement, or an orifice on the...

I believe there is a difference between submitting a file and providing the file to a client. I use AutoCAD files as an example, the client will need the native to allow it to update in the future (I am basing my comments on OnG industry, but it could be applicable to structural drawings as...
One Australian client required that all calculations were "stamped" by a suitable chartered / registered engineer (ie same discipline) even though only one state in Australia requires registration (do not quote me on this wrt structural engineers that may require registration in more states /...
Two things that should be considered during the design:
1. I am not sure about the piping arrangement, but the you need to ensure that the inlet pipework to the PSV is full of liquid
2. If you are considering the effect of external fire, the PSV is relieving vapour (typically). What impact does...
If you were revising a drawing (layout, P&ID, SLD ...), the native file belongs to the owner, and the engineer will send the native file to the client with the invoice. I am sure that no one has a problem with this, and processes are in place to protect the engineer should the native file be...
I am not sure that a set of rules can be put down that will satisfy each and every project. At the end of the day, the benefit of producing a demolition P&ID should be considered against the benefit that it adds. A demolition P&ID for the installation of flanges adds little value, but a...
Surely this is covered by Change Control in your organisation, noting that it is not only a cost saving measure, it is removing more points of failure.
If the correct level of engineering justification is done (HAZOP and calculations), then the risks assessed for removing and not removing the...
Thanks for the reply, but still some of the responses you have received, in my opinion, are unprofessional. I acknowledge that it is only my opinion and that everyone has one. I was thinking longer term than the environment at your current place of employment. You will be extremely lucky if you...
I am flabbergasted by some of the responses, but there are gems of knowledge in there (Ron, zeusfaber, MintJulep). Remember that there are always three sides to any story; employees, employers and the truth. I cannot see how the forum can provide advice without more details. All that was...
To me construction management can be boiled down to two simplistic things. Making sure the construction matches the drawings and that foreman is preparing for the next task. ie be one step behind and one step in front all the time. Hopefully the foreman is thinking beyond the next task, but...
Thank you to Saplanti and Brimmer for your helpful comments. You have both hit the nail on the head of the knowledge we have and what we are trying to achieve. There is always some possibility of an incident, and there is a need to reduce the consequence to reduce the residual risk...

I would be grateful for advice on the use / availability of crack arrestors to arrest long running brittle fractures in a pipeline.
The pipeline of interest is old, transports natural gas, and is made from X42 steel with a low toughness and high ductile brittle transition temperature. I am...
I had a 17", then went to a 15" and then another 15". The 15"s were great (even if the case on the first one was a bit fragile). I appreciated the reduction in weight. The biggest problem for me was keyboard. The 17" one had a full keyboard with number pad, similar to the one on the docking...
My suggestion is to ask the Hysys helpdesk, it is very helpful. I have asked them this question myself in the past and got a fulsome response. I cannot remember the response fully but recall that cp and cv are derived from the enthalpy values, as Apetri states.
MicroMotion has software that can be used with the Coriolis meter for determining the oil cut of a stream. This is typically used on well production streams. I am not sure that it could be used for custody transfer without detailed information on the density of the water and oil; this would be a...
If a HIPPS is put in place to shut down FG to the compressor, ensure that you are not going to bypass the system during commissioning and other non-standard operation (either using bypass valves or manual control operation).
WD40 works to remove old silicone from tiles etc. Not sure that it actually dissolves the silicone, but I have had some luck with it softening the old caulk.
The thing that made me more confident is watching a video of myself presenting. I could then see that the pauses that I believed went on forever and crippled me during the presentation, actually came across as "thought gathering" time and helped the presentation flow. I thought I came across as...
