This may be due, to some extent, to clashes of personality, but it is generally due mainly to differences of role and hence viewpoint which are inherent in the situation. An alternative, described by Horsley (1974), is to let this evolve by negotiation of roles among the managers with division of ‘ownership’ of particular features among them.ĭuring commissioning there is likely to be conflict between individuals. One is to design and impose the organization. There are many variations in the ways of organizing the management team for commissioning. Some of the many variations in commissioning team composition are described by Troyan (1960), Finlayson and Cans (1967) and Garcia (1967). The organization of an extra field-work team for this purpose has been described by Horsley (1974). It may be desirable, particularly on large projects, to create an additional troubleshooting team. Unforeseen problems can often result in considerable demands on resources. It is necessary that the commissioning manager should be able to command the resources necessary to carry through the commissioning. The team may consist of the personnel assigned to the plant supplemented by others who are brought in for the limited period of the commissioning only. The commissioning team for an in-house project should be a strong one, with good technical capability and relevant experience. Experience indicates that it is usually not good practice to attempt to combine the roles of project manager and commissioning manager. The job of the project manager is normally a separate one. Where the project is done in-house, a common practice is to appoint a plant manager for the new plant some time in advance to let him familiarize himself with it, and to make him the commissioning manager. The typical composition of a contractor's commissioning team for a large ammonia plant is given by Horsley and Parkinson as a commissioning manager and deputy, four shift leaders, four assistants, a chemist and mechanical, electrical and instrument specialists. For the case considered, that of a turnkey project, the commissioning manager is appointed by the contractor. It is normal to appoint a commissioning manager who has this responsibility. Responsibility for the commissioning should rest with a single individual. In Lees' Loss Prevention in the Process Industries (Third Edition), 2005 19.1.4 Personnel Produce the final commissioning test report. Produce a punch list (also known as a snags list) that includes the items not completed in any equipment test in the electrical system. The base and detailed design comments should be checked by the commissioning engineer on site. 8.įactory test results, approved test procedures and test sheets should be checked by the commissioning engineer on site. 6.Įnsure there is a reliable power source without fluctuation at site to perform the testing in reliable manner the use of nonstable equipment leads to errors in test results. 4.Ĭonfirm that the approved relay setting and approved schematic drawings are at site (last revision). Insulation resistance and wiring check for all equipment and panels at site. 2.Ĭonfirm all equipment and test tools are on site to start activities as per commissioning program (all with valid calibration certificate for at least one year). The responsibilities of the commissioning engineers and technicians are: 1.Ĭonfirm all equipment is installed in the correct manner. Produce a contingency plan for an emergency should the required circuits be switched off and the situation requires restoration of the operation of one or more circuit during commissioning of existing circuits modification. 7.Īttend commissioning panel meetings on site with other project members. Producing the commissioning file which includes all method statements, single line diagram, site instructions, deviation list and base design comments, various tests, switching program, relay setting calculations, equipments data sheet and specifications, relay manual, relay testing software, and any other required items. Producing the switching program and coordinate with national control center (NCC) local/state/federal electrical supply company (also called the National Control Center, NCC) during energization. 4.Įnsure that the project has the required resources to perform the different tests required and all material, facilities, tools are on site. The responsibilities of the commissioning manager responsibility are: 1.Ĭoordinate with other stakeholders on the project regarding commissioning. A commissioning team consists of the commissioning manager and commissioning engineers.
