In brief
Mohamed Alyassi’s process-engineering experience covers PFDs, P&IDs and specifications; hydraulic and surge analysis; and participation in HAZOP, LOPA and SIL safety reviews for water and energy systems.
01 · Practice
Engineering capabilities
Hydraulics
Steady-state analysis
System-head, flow and pressure assessment for pipeline and network operating cases, with AFT Fathom experience.
Transients
Surge studies
Assessment of pressure envelopes and transient risks, including AFT Impulse experience and evaluation of mitigation requirements.
Process safety
Structured reviews
Experience supporting HAZOP, LOPA and SIL reviews to identify hazards, safeguards and risk-reduction requirements.
02 · Workflow
From basis to review
- Define the basis. Establish system boundaries, operating cases, design criteria and the available source information.
- Represent the process. Translate the system into clear process documents, equipment duties and control intent.
- Test hydraulic behaviour. Examine steady-state performance and transient pressure extremes against system constraints.
- Review risk. Use structured process-safety methods to challenge deviations, consequences and safeguards.
- Document decisions. Record assumptions, interfaces, actions and limitations so the technical basis remains traceable.
03 · Experience
Water and energy systems
From December 2024 to March 2026, Mohamed worked as a Process Engineer at Mott MacDonald across process design, hydraulic and surge studies, and safety reviews for water and energy projects.
