With the continuous advancement of technologies such as automation and information technology, and the ongoing transformation of operation and maintenance models, innovative management models are essential for high-quality industrial development. This is an inevitable requirement. Industries such as oil and gas extraction and pipeline transportation, and power generation have successively begun to implement unmanned operation and management models for their facilities. To ensure... This document, combining new technologies and management models, outlines the safe and stable operation of unmanned stations. It also considers the construction and development needs of relevant domestic industries. Drawing on advanced experience, a comprehensive evaluation method for the operation and risk control level of unmanned stations is proposed, and relevant technical requirements are given. This document aims to guide unmanned depots in identifying weaknesses and potential risks during operation, and to objectively evaluate and effectively assess these risks. This study examines the implementation effects and current technical and management status of unmanned operation modes at facilities with varying basic conditions, aiming to effectively evaluate unmanned facilities across different industries. This provides a basis for assessing the operational level and risk control capabilities of the stations. Furthermore, it can fully identify the transition of relevant stations from traditional management models to unmanned operation. Risks arising from technological upgrades and management changes during the transition of management models will be addressed through management optimization, safety control, emergency management, and response. Such means or technical measures ensure that risks are controllable, thereby safeguarding national industrial security and the safety of people's lives and property.

1 Scope

GB/T 46712-2025 is the Chinese national standard covering judging whether a station can safely run with nobody there - the instrumentation and its coverage, the remote monitoring and the response time of the crew that would have to travel to it, the failure modes that need a human present, and the scoring that says yes or no. At 74,500 words this is one of the largest documents in the catalogue. First edition. Issued on 2 December 2025, it has been in force since 1 July 2026.

This document specifies the general requirements, evaluation system model, evaluation implementation, and other aspects for the comprehensive evaluation of the operation and risk control level of unmanned stations. Content related to ability perfection level assessment. This document applies to the overall operation and risk control level of facilities that have already implemented unmanned operation and those planned to implement unmanned operation management models. Evaluation and related activities, such as at stations in the energy (oil and gas, electricity, new energy, etc.), rail transit, and manufacturing industries.
