Vista has been working with this client for nearly 15 years engineering small projects for several major gas facilities. Work started as a study to help address catastrophic corrosion issues associated with a change in amine (which was solved by changing the amine to Sulfinol), and has led to a long series of gas plant modifications and revamps. Typical work included:
- Engineering plant modifications associated with amine upgrade including new vessels, exchangers, tower internals, pump modifications and associated piping/instrumentation and EIC work;
- Replacing sweetening solvent with Sulfinol;
- Engineering a sulphur degassing facility;
- Installing a sales gas compressor;
- Engineering a variety of piping changes, equipment replacement/repairs required for shutdowns;
- Engineering a 1000 HP multistage centrifugal amine charge pump installation with electric driver;
- Engineering the removal of a failing sulphur pit roof and replacement with new concrete panels without downtime
- Engineering associated with installing several lube oil coalescers, piping changes, PSV evaluation/replacement, revamp of fire & gas detection systems.
Key success factors contributing to this long-term partnership
- Projects have been managed by a Vista Project Manager who is also an owner of Vista;
- Key people who engineered projects remained with the same jobs over the years;
- Rather than a traditional discipline based specialisation, engineers from the Vista “Small Projects Team” multi-tasked to achieve quick turn-around on engineering;
- Working directly/closely with plant operations & maintenance teams and quickly accommodating their needs resulted in minimising down-time/lost production;
- Vista’s diverse experience and repository of past similar engineering solutions allowed selection of tried and tested solutions that worked every time.
