Once a pipeline is successfully constructed and commissioned for operation, it is the responsibility of the operations and maintenance personnel to operate and maintain the pipelines with the safety of the public and operating personnel and to prevent pipeline failures through proactive measures such as periodic maintenance monitoring and check and balance through the SOP.
The scope of any maintenance contract is divided into two parts. These are:
I. The technical scope which involves the technical work which is to be implemented through the related SOPs that shall form part of the procedure to be adopted while the technical jobs related to the maintenance of pipelines are carried out. The maintenance which are required during operation and maintenance of pipelines are comprised of the mechanical maintenance for example valves operation and maintenance, maintenance of filters, leak repairs and welding, etc while the electrical maintenance deals with the control panel (CP) which is a device that detects abnormal currents in an electrical circuit then blocks and protects the circuit.

II. The commercial scope mainly involves the schedule of works to be executed in the contracts involving specification, payment, etc.
