The purpose of any Simultaneous Operations (SIMOPS) Procedure is to provide all personnel from the construction and commissioning groups who are involved with simultaneous operations on the projects with a sound knowledge of the relevant safe work practices and procedures applicable to simultaneous operations.
These Procedures shall also be used to determine the compatibility, interference, and limitations raised during the planning and operational stages of any simultaneous operation.
The activities covered by procedures shall not be limited to the following
- The remaining construction activities (i.e. lifting and rigging, confined space, naked flame, and hot works, etc.)
- The commissioning activities.
- Production activities after partial handover to production.
- Assuring compliance with Permit to Work Procedure.
Should it be deemed necessary, specific operations must be reviewed on a case-by-case basis with a risk assessment such as a job safety analysis being developed as the need arises.
Additionally, the requirements of the SIMOPS Procedure shall ensure that any activity or works in any given area, where joint activities may be ongoing simultaneously, are reviewed and analyzed for potential interference or limitation. The requirements of these Procedures are;
- Establish a mechanism for the review of proposed activities (e.g. meetings, toolbox talks, etc.) to identify department and subcontractor participation.
- Establish a matrix of responsible persons who shall authorize such simultaneous activities.
- Ensure simultaneous activities are controlled and performed in a safe manner by; a) Defining the responsibilities of all personnel involved in the tasks.
- Appointing a Simultaneous Operations Leader (SOL) to coordinate the activities between the different organizations.
- Identifying any preventive safety measures, which shall be implemented prior to commencement of the simultaneous activities
- Limiting the number of simultaneous activities in any given area.
- Avoiding interference during Production Operations after Early Production.
- Establishing communication channels.
- Providing training of all personnel involved in the tasks.
To minimize the potential for personnel injury and equipment damage by:
- Controlling and restricting personnel access to areas where simultaneous activities may be taking place.
- Providing specific instruction for securing (making safe) operations and mustering personnel in case of emergency.
- Ensuring that all personnel involved in the simultaneous tasks are aware of the specifics of simultaneous operations and emergency procedures.
- Identifying hazards and evaluating the consequence of failures.
The SIMOPS Procedures shall further ensure that nothing is done, during the performance of these tasks, to prejudice the safety of personnel or the Plant.
The work activities covered by the SIMOPS Procedure shall include but not be limited to the following;
- Any works significant in nature such as large construction jobs, change-out of major rotating equipment, naked flame and hot works in restricted areas, blasting and painting works, radiography, entry into confined space, rigging and lifting works over live equipment or plant, etc. and which occur in the areas under commissioning control
- Any works that pose a significant hazard such as working in areas where there is a risk of hydrogen sulphide gas (H2S), activities where special chemicals are utilized, work in which multiple subcontractors are involved,
The above examples are not inclusive and other work activities may also be covered under the SIMOPS Procedure.
The requirements of the Simultaneous Operations Procedure (SIMOPS) shall be applied to all construction, commissioning, and production activities to highlight and mitigate any potential restrictions and/or safety impact when planning SIMOPS work activities due to take place at the same time and in the same/vicinity location.
As a minimum, the Procedure shall be distributed to the personnel referenced in the list below.
