LNG Process and Design Issues and Considerations during LNG Plant Design - 2019
Since my re-immersion into LNG plant design and construction, I have found a need to review all aspects of the LNG plant Process Basis of Design and Basic Engineering Design Data (BEDD). As background, my career started as an LNG and natural gas process engineer and then I spend 30 years in the refining EPC area. I now have 40+ years in the oil and gas industry.
During the 30-year refining period, the project owner had refining and delayed coker standards and experienced project engineers involved all aspects of project planning, process design, and project execution.
In 2012, need for engineers with LNG experience led me back into the LNG industry, first as a Project Manager, developing new projects and proposals, and then in LNG Consulting and Expert Witness roles. In many ways, LNG plant design has not change and in many ways, it very different; new tank specifications, instrumentation and facility size to mention a few. FLNG adds another aspect.
Another difference for some new LNG plants, especially the smaller ones, is that they are being developed and built by entrepreneurial teams and companies who employed fewer experienced LNG engineers then I was accustomed to seeing in the refining business. Often these entrepreneurial companies rely too heavily on the EPC contractors’ standard, which are okay, but certainly now specific to a specific owner’s need.
This ‘drove’ me to develop my list of issues and considerations somewhat specific to LNG plants. Attached I share a list of issues which I use as a checklist, especially early in project bidding and development.
I look forward to comments and additions regarding the attachment. It is likely to grow and change.
