REPLACING WIRE ROPE ON A LIFEBOAT M/V MORNING SALUTE

Replacing the wire rope on a ship's lifeboat involves a careful and detailed procedure. Here's an overview:
1. The task usually starts with a thorough inspection of the current condition of the wire ropes.
2. Once the need for replacement is established, the old wire rope is removed. This process should be done with utmost care to prevent any accidental damage to the lifeboat or the davit system.
3. The new wire rope is then installed. It's crucial to ensure that the rope is properly fixed and secured to maintain the stability of the lifeboat.
4. After the replacement, another round of inspection is conducted to check the fixing condition of the new wire ropes.
5. The length of the boat falls (the ropes or cables used to lower the lifeboat) is adjusted as necessary so that the clearances between the davit arm and davit arm stopper at fore and aft are almost the same.
6. Finally, a test is performed to ensure that the lifeboat can be safely lowered to deck level with the new wire rope.
Remember, these are generalized steps and the exact procedure can vary based on the specific make and model of the lifeboat and davit system. Always refer to the maker's manual for precise instructions.
What are some common signs that indicate the need for wire rope replacement on a ship's lifeboat?
There are several signs that can indicate the need for wire rope replacement on a ship's lifeboat. Here are some of the most common ones:
1. Age of the Wire Rope: According to SOLAS (Safety of Life at Sea) rules, wire ropes used in launching appliances for lifeboats, rescue boats, and life rafts may be in service for a maximum of 5 years. After this period, replacement is necessary regardless of the condition of the wire rope.
2. Physical Damage: If there are visible signs of wear and tear such as broken wires, corrosion, abrasion, or deformation, these are clear indicators that the wire rope needs to be replaced.
3. Reduced Diameter: If the diameter of the wire rope has significantly reduced due to wear and tear, it's a sign that the wire rope needs replacement.
4. Incorrect Installation: If the wire rope has been installed in the wrong direction or if the wrong type of wire has been used, it may not last for the intended usage period and would need to be replaced.
5. Deterioration: Deteriorating falls must be renewed as necessary or at intervals of not more than five years, whichever is the earlier.
According to SOLAS (Safety of Life at Sea) rules, the general requirement is that wire ropes used in launching appliances for lifeboats, rescue boats, and life rafts should be replaced at intervals not exceeding 5 years. However, there are a few exceptions to this rule:
1. Impracticability: In cases where it is impracticable to service the wire ropes within the 5-year interval, the Administration may extend this period to a maximum of 17 months.
2. Thorough Examination: In addition to the 5-year replacement interval, there is a requirement for a thorough examination of the wire ropes during the fifth year. This examination ensures that the wire ropes are in good condition and suitable for continued use.
It's important to note that these exceptions are subject to the specific guidelines and regulations of each Administration. Therefore, it is advisable to consult the relevant authorities or the maker's manual for precise information regarding the replacement intervals for wire ropes on a ship's lifeboat.
