GB/T 39215-2020 in English

Standard Overview

This standard is equivalent to ISO 29404:2015, which specifies the logistics information message format of offshore wind turbine (WTG) components from suppliers to installation sites, focusing on the supply chain information flow management during the installation and maintenance stages.

Core content analysis

1. Supply chain process management

2. EPCIS extension mechanism

Based on the EPCIS standard, three types of data fields are extended:

• Plan data: PT field (such as PTArrivalPort)
• Instruction data: ET field (such as ETDeparturePort)
• Event data: New processing status (such as loading_completed)

Key points of technical implementation

Unique identification system

Data carrier selection

RFID (ISO/IEC 18000-6) or QR code (ISO/IEC 16022) is recommended as the physical carrier to ensure AIDC technology compatibility.

Standard evolution background

With the large-scale development of offshore wind power projects, traditional paper documents can no longer meet the needs of cross-border supply chain collaboration. This standard solves the following problems by unifying EPCIS extension fields:

1. Information gaps in multimodal transport
2. Real-time coordination between installation vessels and ports
3. Reverse logistics tracking during maintenance period

Implementation suggestions

It is recommended that enterprises implement the standard in three stages:

1. Identification system construction: Standardize GLN/SGTIN encoding according to Chapter 7
2. EPCIS system transformation: Refer to Appendix A to expand XMLSchema
3. Process alignment: Establish event mapping rules based on Table B.1
