Abstract: To achieve the construction goal of "full digital handover, full intelligent operation and full life cycle management" of the China-Russia Eastern Gas Pipeline Project, the basic process and working mechanism of digital handover were proposed, and the significance to pipeline construction and operation management was pointed out. The data docking channel was unblocked by unifying the data acquisition standard. With the full life cycle database as the carrier, the association, storage and sharing of data were realized. Hence, the digital handover was promoted in order to meet the demand of simultaneous delivery of entity pipelines and digital pipelines and ensure the traceability of data history. By establishing an interface with the data warehouse for data calls, the orderly transfer of data from the construction phase to the operation phase was ensured, and the docking application of the digital handover data and the pipeline integrity management system was realized. All of these not only present the value of data to the greatest extent, but also provide data guarantee for intelligent pipeline construction and integrity management.
