The SIMOPS study is carried out through a workshop to be attended by production and Construction team members and facilitated by a competent study leader.   A matrix of all production and construction is developed at the beginning of workshop session. The issues related to interfacing of the risk are then discussed through cross reference of each Construction activity with each production activity.  Based upon the discussions the simultaneous operation activity is to be designated as:   The issues related to interfacing of the risk are discussed through cross reference of each construction activity with each production operation activities.  Based upon the discussions the activity has been designated:  

Y- Permitted: Where there are no hazards or risk profile by performing the activities concurrently. It means that the two activities can be carried out following normal work procedures.

N-Not Permitted: Where the hazards introduced are considered excessive and the activities should not be conducted concurrently.

R-Restricted: Where potential hazards or risk could be elevated by the simultaneous operations and may require restrictions to be imposed or contingencies implemented. Such Restrictions are indicated as R1, R2 & so on and description of that restriction is tabulated.
