Objectives   The purpose of this paper is to explore the feasibility of applying heterogeneous network and internet of things (IoT) technology to the remote monitoring of offshore facilities.

  Methods   Therefore, this study proposes an experimental platform for the corrosion acceleration of IoT based on a heterogeneous network composed of a perception layer, network layer and application layer. The salt spray experiment method is adopted to realize the simulation of marine atmospheric corrosion on land, and the perception layer collects simulated corrosion environment data and corrosion effect data. Taking the characteristics of the offshore production environment and existing network transmission technology into consideration, the network layer completes the task of data transmission through the heterogeneous network composed by ZigBee, LoRa, WiFi and Ethernet. Finally, the corrosion information is completed via a web application in the application layer.

  Results   This experimental platform effectively simulates the acceleration of salt spray corrosion in an ocean atmosphere, as well as data transmission and remote monitoring in complex environments.

  Conclusions   The construction of a heterogeneous network-based corrosion acceleration experiment platform can provide a basis for follow-up research on corrosion laws based on big data and artificial intelligence technology in order to predict the corrosion failure of marine structures.
