01A / How I work

A visible line from design basis to operating result.

Each case is structured for a quick technical review: personal role, engineering challenge, selected deliverables, multi-discipline interfaces, and the outcome the work was intended to produce.

01
Define the design basis
Clarify operating cases, process requirements, constraints, safeguards, and the decision the work must support.
02
Analyse the system
Use production data, simulation, hydraulics, equipment assessment, and risk review to test viable options.
03
Translate into deliverables
Connect calculations to PFD/P&ID development, technical specifications, material criteria, and cost or procurement inputs.
04
Coordinate the interfaces
Align process intent with operations, mechanical, piping, instrumentation, HSE, construction, and commercial teams.
05
Close the field loop
Support construction and commissioning, then compare post-start-up performance with the original engineering basis.
