Abstract
Accuracy management of production materials plays an important role in offshore platform projects. To improve both the efficiency and accuracy of material management in offshore platform projects, a novel material management system characterized by the notion of a material information unit was proposed in light of a review of the industrial Internet of Things and multi-agent technology. The material information unit is used to carry data on production materials and serve as a basic information unit in the system. Furthermore, agents of different functions are employed to tackle assorted tasks. Using this system, material information can be precisely recorded, tracked, and traced during the manufacture of offshore platforms. In addition to this system, an algorithm targeting at multi-agent negotiation is designed. Finally, a prototype system is developed to verify the feasibility and efficiency of this material management process.
Highlights
As the ocean resources such as marine oil and gas have been explored, these years have witnessed the sharp demand for offshore engineering structures such as offshore platforms and pipe ships, and it is expected to continue to grow
With the development of the Internet of Things (IoT) and its supporting technology, material information management that applies to every single object has been technically feasible since 2010,3 but it needs to be equipped with an enterprise data system that has strong information processing capability
The following conclusions can be drawn after analyzing the situation regarding offshore platform project (OPP) material management: 1. the traceable entity unit (TEU) was proposed to facilitate material management during the OPP manufacturing process, it is only a conceptual model, lacking coding rules and content specifications, which is far from satisfactory for efficient OPP material information management
Summary
As the ocean resources such as marine oil and gas have been explored, these years have witnessed the sharp demand for offshore engineering structures such as offshore platforms and pipe ships, and it is expected to continue to grow. Nowadays in China, most marine structures are manufactured by shipyards whose management methods are undeveloped, leading to numerous problems in material management such as waste and additional costs. Since the 1990s, information technology has been applied to the control of production materials using different methods to achieve higher production efficiency and more accurate material management in the OPP manufacturing process. With the development of the Internet of Things (IoT) and its supporting technology, material information management that applies to every single object has been technically feasible since 2010,3 but it needs to be equipped with an enterprise data system that has strong information processing capability
