Engineering Design Reviews

Engineering Design Reviews

Engineering design is usually a collaborated effort. Different teams from different disciplines of engineering need to collaborate on the same project. Naturally, the work done by each team / participant needs to be reviewed by others on regular intervals. Engineering Design Reviews are meetings held for these review sessions where different stakeholders can develop a better common understanding of the work in progress.

Depending on the engineering deliverables being reviewed, their are some commonly practiced review meetings which have now become quite standard.

3D Model Design Reviews

The 3D Model design reviews are conducted to facilitate the engineering and erection of units during construction phase, to provide a check on technical and personnel safety aspects, operability and maintenance aspects, etc. The review normally is conducted at different stages of completeness of the 3D model, as more and more details become available in the 3D model.

Fire Safety Review

A Fire safety review is a safety review process for assessment of fire risk from potential flammable release hazards associated with the infrastructure of selected plant sections. The objective of Fire Safety Review is to ensure that a fire, hydrocarbon spill or vapor release anywhere in the plant can be adequately dealt with to prevent escalation of the emergency (fires or explosion).


HAZOP- an abbreviated term of “HAZards and OPerability”- is defined as: “The application of a formal systematic critical examination of the process and engineering intentions of the new facilities, to assess the hazard potential of mal-operation or malfunction of individual items of equipment and the consequent effects on the facility as a whole”. The objective of HAZOP is to assess the hazard potential of mal-operation or malfunction of equipment and the consequent effects on the facility.

Pre-Startup Safety Review (PSSR)

The PSSR is a safety review conducted prior to startup (commissioning) of a new or modified processing / manufacturing plant or facility to ensure that installations meet the original design or operating intent, to catch and re-assess any potential hazard due to changes during the detailed engineering and construction phase of a project. In other words, it ensures the “Ready for Start-up” status of process facility/units. PSSR is conducted by a team, lead by a Leader. The leader is normally a representative of operation group because they are the ultimate customer of the facility.

Process Design Safety Review

Process design safety review is a planned and systematic brainstorming meeting for identification of potential hazards, assessment of risk and reviewing the  readiness and effectiveness of risk control measures to ensure safety for personnel and equipment systems in a process plant.
