Abstract: Walkthrough shall be conducted in the final stage of construction of petrochemical projects. As a crucial part of the walkthrough, electrical construction acceptance directly affects the project pre-commissioning schedule and the long-term safe and continuous operation in the future. The organization and acceptance of electrical walkthrough is very important. From the point of view of electrical engineers, this paper describes the inspection details of electrical walkthrough in petrochemical projects, and analyzes and discusses the common problems in walkthrough, providing reference for the design of similar projects in the future.

Key words: walkthrough, petrochemical project, electrical
