System and method for collaborative design of offshore oil and gas engineering

The invention discloses an offshore oil and gas engineering collaborative design system and method, and relates to the technical field of offshore oil and gas engineering design. Comprising a design business process management module, a design workstation module, a design business data module and a design data asset module, and the design business data module is in bidirectional communication connection with the design business process management module, the design workstation module and the design data asset module. The design work station module is in one-way communication connection with the design business process management module and the design data asset module. According to the method, a full-design-chain digital design mode is provided for the offshore oil and gas facilities, a complex, multidirectional and isolated design service is converted into a working mode which takes a service process as a drive, design data as a core and a digital design object as a carrier, and closed-loop controllability o
