Compliance overview
Scope and applicability
This standard applies to all Chinese-flagged seagoing vessels engaged in international voyages, as well as domestic coastal vessels of 500 gross tonnage or above or with a main engine total power of 750 kW or above that use internal combustion engines or electric motors as main propulsion. Other Chinese-flagged vessels may refer to this standard voluntarily. It is mandatory for the specified vessel categories. The standard covers both motor vessels (internal combustion engine ships) and electrically-propelled vessels, which is a new addition compared to the previous GB 18436-2001 version.
Technical requirements
The standard specifies the recording content for engine log books, which differs between motor vessels and electrically-propelled vessels. For motor vessels, it mandates recording main engine parameters including total revolutions, average speed, load indication, turbocharger speed, temperatures at multiple measurement points (cylinder exhaust, turbocharger bearings, scavenging air, cooling water, thrust bearings, etc.), pressures (sea water, lubricating oil, common rail oil, servo oil, starting air, control air), fuel and lubricant consumption records, boiler parameters, and equipment running hours. For electrically-propelled vessels, the standard requires recording main generator set parameters, propulsion motor load and speed, insulation values, frequency converter data, and transformer temperatures. The standard also defines recording requirements such as using indelible blue-black or black ink, sequential page numbering without tearing or adding pages, and proper correction procedures with signatures. The chief engineer must review and sign the log daily. For vessels with Auto-0 automation level, motor vessel logs must record at least 3 shifts per day, while electrically-propelled vessel logs must record 2 shifts per day. Additionally, the standard prescribes storage requirements (logs must be retained onboard for at least 2 years and taken during ship abandonment), format and layout specifications (cover dimensions, page numbering systems using Roman and Arabic numerals), and printing requirements including specific paper materials (2mm cardboard covers with kraft paper, 100g offset paper for inner pages), font specifications, and standardized table formats as defined in the normative appendices.
Testing methods
This standard does not involve laboratory testing methods. Instead, it establishes documentation and record-keeping procedures for shipboard operations. The key evaluation aspects include: verification that engine log books contain all required parameters for the applicable vessel type (motor vessel or electrically-propelled vessel); compliance checking of recording practices such as ink type, correction methods, and shift recording frequency; inspection of format and layout conformity with the normative appendix figures (cover style, page layout, table structure); and verification of printing specifications including paper quality, dimensions, and font requirements as specified in the standard's tables.
FAQs
What vessels are regulated under GB 18436-2022?
GB 18436-2022 is mandatory for all Chinese-flagged international voyaging seagoing vessels, and domestic coastal vessels of 500 GT or above or with main engine power of 750 kW or above. It applies to both motor vessels and electrically-propelled vessels. Other Chinese-flagged vessels may refer to it on a voluntary basis.
What are the key changes from GB 18436-2001?
The 2022 revision adds electrically-propelled vessel log book content (a new category), updates the recording content for motor vessels, modifies recording and format requirements, and removes the registration and issuance rules that were in the 2001 version. It also adds new format layout styles for electrically-propelled vessels in the normative appendices.
How long must engine log books be retained onboard?
Used engine log books must be retained onboard for at least 2 years under the care of the chief engineer. In the event of a maritime incident, the chief engineer must safeguard the log book and bring it when abandoning ship for maritime investigation purposes. Compliance with retention requirements is essential for regulatory inspections.
The summary above provides a high-level overview of GB 18436-2022. To ensure complete compliance for your vessels operating under Chinese flag, a precise and professional translation of the full technical specifications—including all recording content tables, format layout diagrams, and printing requirements—is essential.
