Abstract:

Against the background of "dual carbon" goals, the operation and management of petrochemical enterprises is undergoing transformation and upgrading from "physical assets" to the dual-drive of "digital assets + physical assets”. Digital delivery has gradually become a standard configuration for large-scale projects such as integrated refining and chemical plants and LNG receiving terminals. However, there is still a lack of unified definition of the connotation scope, pricing base and pricing method of digital delivery cost, leading to frequent disputes during cost estimation, contract negotiation and payment. Based on a systematic review of the connotation and composition of digital delivery cost in the petrochemical industry, this paper compares two mainstream models taking the engineering cost and the basic design and detailed design fee as the pricing base, respectively. It demonstrates the rationality of using the basic design and detailed design fee as the pricing base, and proposes a dynamic rate model of "engineering design correlation coefficient + multi-dimensional characteristic coefficient + scenario adjustment coefficient", providing a reference for the quota revision in the petrochemical industry, the investment decision-making of enterprises, and the bidding and quotation of engineering companies.
