3. SIMOPS Risk Assessment Process 
Purpose of the SIMOPS risk assessment process was to review and evaluate in detail the simultaneous 
construction, commissioning, start-up and operations activities planned, with the final aim of: 
• Identifying the additional hazards introduced by the SIMOPS; 
• Assessing the relevant level of risk; 
• Verify the adequacy of the planned control measure; 
• Identifying additional risk reduction measures; 
• Provide input to Permit To Work process for embedding additional controls. 
All the project’s parties as plant owner, PMC, main contractor, subcontractors and vendors were actively 
involved in the entire SIMOPS risk assessment process. 
3.1 SIMOPS Assessment Study Workshop 
The SIMOPS assessment study workshop is the initiator event of SIMOPS risk assessment process, the key 
moment to share necessary information and to proper coordinate the involved parties. 
Participation of a multidisciplinary study group from all project’s actors was a mandatory requirement. 
Presence of following roles was requested: construction manager, commissioning manager; operations 
representatives, site HSE manager, process and process safety specialists. The workshop was led by 
SIMOPS facilitator, having the responsibility to moderate and to stimulate the discussion between participants. 
Due to the fact that SIMOPS assessment is strictly related to the plant area where simultaneous operations 
are carries out, different SIMOPS workshops were executed according to planned simultaneous activities and 
related plant location. 
During each SIMOPS workshop the below steps were undertaken under the guidance of the SIMOPS 
facilitator: 
• Identification of the SIMOPS scenarios, means identification of the concurrent activities to be carried out 
during hydrocarbon introduction; 
• Identification of the related hazards; 
• Evaluation of the risk of simultaneous execution of the activities; 
• Identification of control measures and/or operating procedures already planned and consequent 
assignment of the responsibility for their implementation; 
• Evaluation of the residual risk with risk control measures already in place; 
• Identification of additional risk control measures, if required; 
• Assignment of responsible person for the implementation of identified countermeasure. 
In addition to the above, during the workshop propaedeutic documentation was made available as follows: 
• Updated schedule of construction, pre-commissioning, commissioning and start-up activities; 
• Process Flow Diagrams (PFD) and Piping & Instrumentation Diagrams (PID); 
• Plant layouts and equipment layouts;

• Material Safety Datasheet (MSD) of handled substance; 
• Hazardous areas classification drawings; 
• Detail regarding manning level and worker distribution on area involving SIMOPS; 
• Layout showing Permit To Work areas; 
• Layouts showing location of temporary construction devices as: crane, diesel generator, welding machines, 
scaffolding, etc.; 
• Quantitative Risk Assessment (QRA) and consequence analysis developed during detailed design.
