Escopo e aplicabilidade

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.

Requisitos técnicos

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.

Métodos de ensaio

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.

Perguntas frequentes

What products and equipment are regulated under GB 15359-2021?
