Compliance-Überblick

Dieser Überblick ist derzeit nur auf Englisch verfügbar.

Geltungsbereich und Anwendbarkeit

This standard is mandatory for Chinese-flagged seagoing vessels engaged in international voyages, as well as coastal navigation vessels of 500 gross tonnage and above, or with a total main engine power of 750 kW and above. It is not applicable to inland waterway vessels or smaller coastal craft below these thresholds. The standard serves as the core regulatory document for the *Deck Log Book* used aboard these regulated ships.

Technische Anforderungen

The standard specifies the comprehensive content and recording requirements for the Deck Log Book. It mandates that the logbook be divided into a left page and a right page. The left page must include sailing records, meteorological and sea state records, watchkeeping details, tank sounding records, and noon measurements. The right page must contain a remarks column and a major events record. Entries must be made with indelible blue-black or black ink, and any corrections must be signed and dated by the correcting officer. Key recording content includes detailed navigation parameters such as gyro-compass and magnetic compass courses, true course, leeway and drift angle, and log readings. Meteorological observations must follow specific symbols and scales for weather phenomena, visibility, wind force, cloud types, and wave levels. The standard also requires the recording of critical operational events, including arrival/departure procedures, pilotage, anchoring, AIS operation, and emergency drills. The Chief Officer is responsible for the daily review and safekeeping of the logbook, while the Master must supervise and sign to ensure completeness. Furthermore, the standard defines strict formatting and printing requirements. It dictates the exact layout, page numbering (Roman numerals for preliminary pages, Arabic for the 100-page main body), and material specifications, such as using 2mm cardboard for the cover and 100g offset paper for inner pages. Specific font and size requirements (e.g., *Song typeface*, *Kai typeface*) are mandated for different sections, including the cover, ship's main particulars table, and daily entry pages.

Prüfverfahren

This standard does not involve laboratory testing methods. Instead, it prescribes observation and recording procedures for maritime navigation. Key observational protocols include standardized methods for determining sea surface visibility, wind force levels (based on the Beaufort scale), cloud classification, and wave height assessment. Compliance is verified through the accurate and chronological completion of the logbook entries as specified in the standard's appendices.
