1 Objective and target group 2 System description 2.1 Introduction 2.2 Design basis 2.3 Process description 2.4 Utility systems, chemicals and catalyst requirements 2.5 Analysis (sampling points, etc.) 2.6 HSE requirements 3 System operation, including process control 3.1 Normal operation 3.2 Normal start-up 3.3 Normal shut down 3.4 Special operations 3.5 Routine operations 4 Maintenance 4.1 Depressurization and flushing 4.2 Maintenance 5 System protection 5.1 Premises 5.2 Process and emergency shut-down functions 5.3 Specific equipment protection 5.4 Pressure safety equipment (relief valves, rupture disks, etc.) 5.5 Car seals, key locks and key interlocks 6 Specific design solutions 7 Technical data, calculations and drawings 8 Additional information 8.1 Definitions and abbreviations 8.2 Changes from previous version 8.3 References

Section 4 shall describe maintenance sequence, including how to shut down and drain equipment and parts of the system, relevant conclusions from HAZOP and other evaluations, and any other relevant considerations; reference to supplier documentation for individual equipment maintenance procedures can be done in addition.

Section 5 shall include a list of all the isolation valves located in the pressure-relief system piping which could isolate pressure relief valves in the system. The required position and the reason for the lock or the seal shall be included.

Section 6 shall give details about the specific design solutions chosen for equipment, instrumentation and materials. The reasoning behind the specific design solutions shall also be given in this section, e.g. the reason for choosing a specific level control instrument, the specific compressor configuration, the specific heat exchanger configuration etc. Any limitations to the operation caused by the e.g. the material selection or e.g. the design capacity shall be explained in this section. This could be low or high temperature limitations, throughput limitations for heat exchangers, operating conditions which reduce the lifetime of an equipment unit etc.

Section 7 shall include the relevant technical data, calculations and drawings not covered by a reference to a separate document in section 8.3.

Section 8.2 shall be used to log the performed modifications affecting the described system design and operation. For a new built installation this section will be empty. For a modification this section shall describe the changes resulting from the modification only once, i.e. changes between the versions issued internally throughout the modification project shall not be commented.
