North Sea Update
Firstly, I apologise that it has been quite some time since my last blog so instead of going into detail on any one subject I will try and write a bullet point list of the things that have been occupying my time and some points of engineering interest:
1) Financial. I technically approved an estimate for £2.5 million and some change. This was for the replacement of the high pressure discharge cooler. This covers the detailed engineering and offshore construction costs for the project and I had to go through and scrutinise each line of the 35 page estimate because there was only £1.8 million left in the budget.
2) Flushing skid Issue One. I had to prove to the process engineer that the formula used by the vendor would work. The vendor had stated in an email the formula they had used to calculate flowrate but the process engineer was unconvinced. Although the query went back to the vendor I thought it was quicker to try and prove it myself. See the attached picture for details and hopefully I’m not wrong because the flushing has now occurred.
3) Offshore. I managed to get offshore again and I did some line walking, which involves trying to decipher process and instrumentation diagrams and then trying to see if what is on the diagram matches what is actually on the asset. I was also involved in an isolation for potable water prior to the issue of a permit.
4) Flushing Skid Issue Two. When there was a problem with the powering the flushing skid it was suggested that the existing hydraulic pressure unit (HPU) may be suitable to flush the system. I did a quick calculation to prove that this wasn’t possible (below):
5) Apart from that, I have been doing all the project engineer stuff for my other projects, which is keeping me busy. Hopefully, my next blog won’t take as long.
