2Terms
2.0.1 Structured data refers to the information that can be decomposed into multiple interrelated components after analysis. Each component has a clear hierarchical structure，which can be managed through relational database and follows certain operation specifications，such as intelligent P&ID，3D model and other data based on database management，or data that can be expressed in a two-dimensional table. Unstructured data refers to the information in the form of documents，such as documents，graphics，drawings，etc.
Structured data can be generated and managed by intelligent engineering software or extracted from unstructured data.
The digitalization process also includes the establishment of information model with plant objects as the core，consisting of data，documents，3D models and their associated relationships.
2.0.2 Digital static information refers to the engineering information in the engineering，procurement，construction and other stages generated during the construction of a project. Digital dynamic information refers to the real-time information generated during the operation and maintenance stage of a plant that reflects the operating status of plant objects.
2.0.3Digital delivery
With the plant object as the core，the work process that digitally creates the static information generated in the construction stage of the engineering project until the handover. It covers information delivery policy development，information delivery basis development，information delivery solution development，information integration and verification，information handover and information acceptance.
2.0.4 A plant object refers to an entity with unique identification that can be maintained during the operation and maintenance of a plant，such as a pump，compressor，pipeline，instrument，etc.
2.0.5 Plant objects can be divided into pumps，columns and heat exchangers according to their functions. Taking pumps as an example，they can be divided into the power pump and positive displacement pump according to their structures.
The plant object class has inheritance relationship. For example，the pump class is the superclass，the power pump and positive displacement pump are the subclasses，and the subclass inherits the attributes of the superclass
2.0.6 Plant breakdown structure
The tree structure that is organized according to certain classification principles and coding system and established to reflect the plant objects based on the process flow or layout.
2.0.7 Information granularity
It reflects the level of detail for plant object information，which is related to information usage requirements，information collection and processing capacity and cost.
2.0.8 The digital delivery requires the definition of class library，which is used to describe the data，documents and other information related to the plant objects and the relationship between them. Taking the flowmeter 1000-FT-0008 as an example，various information related to the object is organized as shown in Figure 1.
3 Basic requirements
3.0.1 Project digital delivery is a process from digital creation to transfer of static information generated during the construction of the project，including information delivery strategy development，delivery basis
development，information delivery scheme development，information integration and verification，information transfer and information acceptance. Digital delivery and project construction shall be carried out and coordinated with the project construction at the same time to ensure the consistence，accuracy and integrity of information. If itis carried out after the project is completed，it is easy to cause information omission and redundant work.
3.0.2 The documents for handing over a completed project refers to the final version of documents to be delivered to the construction unit in the whole process of design，procurement and construction，excluding intermediate information. Intermediate information refers to the intermediate process information generated to form the final deliverables agreed in the contract，such as calculation process information in the design process，intermediate version documents and other information. However，the inspection report，quality inspection record and other technical documents generated during the project construction that need to be delivered belong to the final deliverables.
3.0.3 The necessary information is information that must be delivered，and is of the nature of mandatory delivery; the optional information is information that the delivery party can choose to deliver，and is of non-mandatory nature. Taking the vessel class as an example，the tag number，service，and material are necessary information; the fluid operating density is optional information.
