Compliance overview
Scope and applicability
This standard applies to maritime light vessels (lightships) and large navigational buoys (LANBY) deployed in China's sea areas, seaports, and sea-reaching estuaries. It is specifically designed for vessels and buoys equipped with high-intensity lights and auxiliary navigation devices. Engineers designing or maintaining large-scale floating aids to navigation for Chinese waters must comply with this standard.
Technical requirements
The standard specifies the marking characteristics for both day and night operations. For daytime features, it defines the structural shapes (ship-form for light vessels, cylindrical for large buoys), mandates red surface colors compliant with GB 17381, and regulates the typography and placement of identification names. For nighttime features, it mandates white light colors and sets strict regulations on nominal light range, rhythm, and flashing periods. Compliance with these exact visual signaling parameters is mandatory for safe maritime navigation. Additionally, the standard outlines requirements for nautical chart symbols in accordance with GB 12319.
Testing methods
While traditional destructive testing is not the primary focus, the standard specifies performance evaluation criteria for acoustic and radio navigational equipment. This includes verifying the transmission of Morse code for sound signals and radar beacons, ensuring a minimum operational range of 10 nautical miles. Furthermore, it outlines functional checks for Physical AIS Aids to Navigation (AtoN), requiring them to possess channel broadcast and reception capabilities with a minimum range of 10 nautical miles. All equipment must be evaluated against these specific operational distance and signaling criteria.
FAQs
What products and equipment are regulated under GB 15359-2021?
This standard regulates maritime light vessels (lightships) and large navigational buoys (LANBY) with a waterline diameter of over 8 meters, deployed in China's sea areas, seaports, and estuaries.
Are there any significant updates from the previous version of GB 15359?
Yes, it replaces GB 15359-1994. Key updates include modified requirements for nighttime characteristics, sound signals, radar beacons, and the addition of requirements for Physical AIS Aids to Navigation (AtoN).
How does GB 15359-2021 relate to other international maritime standards?
It aligns with the Chinese maritime standard framework by referencing GB 4696 for visual aids and GB 12319 for chart symbols, ensuring localized compliance for navigational lighting and marking within Chinese waters.
