Abstract: Starting from the requirements of intelligent plant construction, this paper discusses the objectives, significance and content of digital delivery standards for petrochemical engineering by analyzing the difficulties of intelligent plant construction and the situation of digital factory construction in enterprises, and explores the implementation process and effect of digital delivery standards in engineering projects. The release and implementation of digital delivery standards provides unified compliance for all engineering participants, standardizes the delivery content and process, ensures the quality of delivery, reduces the costs of project communication, data exchange, information collection and integration, shortens the construction cycle of digital plant, and improves the efficiency of asset management.

Key words: digitization, digital delivery, digital factory
