1.Question: How often should a comprehensive inspection of the anchor chain be carried out?
Answer: It is generally recommended to conduct a preliminary visual inspection before and after each ship's voyage. A more comprehensive inspection, including a detailed check of the chain links, connecting components, etc., should be carried out at least once a month. For ships operating in harsh environments for an extended period, the inspection frequency should be appropriately increased.
2.Question: How to determine if the wear of the anchor chain exceeds the standard?
Answer: Use tools such as calipers to measure the diameter of the chain links and compare it with the original design dimensions. Generally, if the wear of a chain link exceeds 10% of its original diameter, it can be considered that the wear exceeds the standard, and replacement or repair should be considered.
3.Question: What cleaning agents can be used to clean the anchor chain?
Answer: For general dirt and rust, clean water and a wire brush can be used for cleaning. If the rust is severe, a mild acidic rust remover can be used, but it should be rinsed thoroughly with clean water in a timely manner to avoid residues. There are also special ship anchor chain cleaning agents that can effectively remove oil stains, marine organisms, etc., and have less corrosiveness to the anchor chain material.
4.Question: Is there a pressure requirement for flushing the anchor chain with a high - pressure water gun?
Answer: Usually, a high - pressure water gun with a pressure of 1000 - 3000 PSI (pounds per square inch) is more appropriate. If the pressure is too low, it may not effectively remove debris, and if the pressure is too high, it may damage the surface of the anchor chain.
5.Question: Which protective paint should be selected to maintain the anchor chain?
Answer: Ship - specific anti - rust paint with good anti - corrosion performance, such as epoxy zinc - rich paint, should be selected. This kind of paint can form a firm protective film on the surface of the anchor chain, effectively preventing seawater corrosion and having good wear resistance.
6.Question: What are the precautions for applying anti - rust grease?
Answer: Ensure that the surface of the anchor chain is clean and dry before application. The grease should be evenly applied to the surface and joints of the chain links, especially in parts prone to wear. At the same time, pay attention to choosing anti - rust grease suitable for the marine environment, and avoid using grease that is easily washed away by seawater or loses its performance at low temperatures.
7.Question: Does the anchor chain compartment need special moisture - proof treatment?
Answer: Yes. Moisture - proof paint can be applied to the bulkheads and floors of the anchor chain compartment, and ventilation equipment such as exhaust fans can be installed to keep the air in the compartment circulating. If possible, desiccants can also be placed to absorb excess moisture in the compartment.
8.Question: What are the requirements for placing the anchor chain in the anchor chain compartment?
Answer: It should be neatly coiled and arranged, stratified and arranged in a certain order to avoid entanglement and extrusion between the chain links. At the same time, leave enough space for inspection and maintenance. The end of the anchor chain should be fixed firmly to prevent it from loosening when the ship shakes.
9.Question: Can a slightly deformed anchor chain be used continuously?
Answer: If it is a slight deformation, after evaluation by professionals to confirm that it does not affect the strength and performance of the anchor chain, it can be used continuously, but enhanced monitoring is required. If the deformation is caused by excessive local stress or other abnormal conditions, even if it is slight, further inspection is recommended, and correction or replacement may be necessary.
10.Question: How often is the braking device tested?
Answer: Generally, the braking device should be functionally tested before each anchor - raising and anchor - dropping operation to ensure its sensitivity and reliability. In addition, a detailed inspection and test of the braking device, including braking response time, braking force, etc., should also be included in the monthly comprehensive inspection.
