Precautions for inspection of lifeboat related equipment

Release time:


Generally according to the lifeboat landing mode, it can be divided into two categories: davit landing and free landing. Hanger landing type can be divided into single-point inverted arm type and gravity slide rail type. When a single-point inverted boom boat is in operation, the boat generally descends to the vicinity of the deck of the boat, and the boat has a large range of movement. Gravity slide rail boat frame relies on the gravity of the lifeboat, and the boat can move in a small range. Because free-fall lifeboats must rely on guide rails and wire ropes to retract, the whole process is more troublesome. Therefore, for free-fall lifeboats, we generally only perform visual inspections and do not perform actual launch inspections.

1.Appearance inspection

 When inspectors arrive at the lifeboat premises, they should first use professional judgment to determine whether the lifeboat is compatible with the davit. In particular, after some old ships have undergone major repairs, alterations or maritime incidents, the lifeboats have been renewed and the boat frames are still old. In the process, some shipping companies or shipyards were unable to find lifeboats of the same model for a while, and only rushed to install similar or close lifeboats. At this time, we can find that there is a clear difference between the lifeboat and the davit in terms of length and width, and it does not seem to match.

2. Equipment layout

 In addition to free-fall launching lifeboats, there are generally three or two sets of launching mechanisms for lifeboats: one set should be operated by one person at a certain position on the side of the ship's deck, and one set should be able to be operated at a certain position inside the lifeboat. Use the gravity block of the winch. The first two are mandatory requirements of the Convention.

3. Inspection of winch braking device

In order to prevent the lifeboat from becoming abnormal in an emergency, and to ensure the safety and stability of the crew during the lifeboat landing, the winch brake device plays a very important role. When the lifeboat is approaching the deck level of the boat at a faster speed, the inspector may signal the winch to brake. If the lifeboat cannot be controlled to fall or slide for a long distance to stop, it can indicate a problem with the winch braking. Under normal circumstances, the winch braking device should be in the braking state.
