The China Maritime Safety Administration (MSA) has issued a notice announcing a special safety inspection period to prevent the failure of ships’ mechanical and electrical equipment from 7 April 2024 until 31 October 2024.
Lloyd’s Register issued an article to provide details about this period of extra scrutiny for ships entering Chinese ports and shipyards, advising foreign classification societies in China to enhance and improve:
- Survey, inspection and testing during new construction
- Survey of conversion, renewal or repair of mechanical and electrical equipment
- Survey quality to reduce the risk of mechanical and electrical equipment failure.
In particular, China MSA informs that maritime management agencies at all levels should conduct detailed inspections of ships’ electromechanical equipment in conjunction with daily ship safety inspections.
If it is discovered through various channels that a ship has experienced electromechanical equipment failure, special inspections will be carried out in principle. For ships that have experienced two or more electromechanical equipment failures within 12 months, the maritime administration agency will invite shipping companies and ship inspection agencies to jointly conduct inspections, and require the ships to submit fault analysis reports and measures to prevent ship electromechanical equipment failures
As explained, any such equipment failures on board must be reported promptly to the local MSA and follow Chinese port authority safety requirements. Failure to comply could result in delays, detention in port and legal consequences.
Preventing main propulsion unit failure requires self-examination from the aspects of oil, gas, water, and electricity. It should focus on the fuel system, lubricating oil system, air system, cooling water system and main engine control system.
7 key points to check whether the main propulsion device (prime mover) is normal
- Whether the fuel system of the main propulsion unit is normal (fuel supply unit, high-pressure oil pump, oil pipe, oil leakage monitoring, fuel heating, automatic fuel pump switching (if any), etc.).
- Whether the communication facilities such as the console and driving platform clock are normal, and whether the nearby instruments such as the tachometer are normal.
- Is the starting air system of the main propulsion device normal (main starting air bottle pressure, main air compressor, main starting valve, cylinder starting valve, air distributor, etc.).
- Whether the main engine’s lubricating oil system is normal (whether there are traces of leakage in the pipelines and filter joints, whether the pressure gauge display is normal, whether the sensor joints are firm, whether the lubricating oil pump automatically switches (if any), etc.).
- Whether the cooling water system of the main engine is normal (whether there are traces of leakage in the pipelines and coolers, whether the pressure gauge display is normal, whether the sensor joint is firm, whether the cooling water pump switches automatically (if any), etc.).
- Check whether the host control air system is normal (control air pressure, control whether there is water in the air, etc.).
- Main engine retreat measures (adjustable propeller blade pitch control system, clutch).
