Lifeboats are an important survival tool in the event of a shipwreck at sea. When using a lifeboat, it is important to pay attention to the safe operation method. Lifeboat manufacturers have summarized the following points.
1. Inspect and maintain life-saving equipment on a regular basis in accordance with regulations. The captain must approve the use of boat life saving equipment.
2. Check the equipment and spare parts before putting the boat in the water, davit machinery, brake test and guide wheel, davit pulley, wire rope, davit hook, and other checks to ensure there are no problems, plug the bottom of the boat plug, and get the boat bow stern cable ready.
3. Place the lifeboat under the leadership of the duty chief sailor or driver, who must master the wind flow and ship speed. In general, the lifeboat should be parked after the remaining speed is not too high, and carried out in the ship downwind a side.
Prevent the boat life saving equipment from colliding with the ship when launching it in the wind and waves. When releasing the hooks, try to coordinate your movements as much as possible so that you can release all of the hooks at once, avoiding previous releases. The davit rope and its pulley should be lassoed ahead of time, and then pulled tight in time to avoid shaking injury.
4. All boat crew members should wear life jackets and helmets, with a maximum of three people, and obey the captain's command. Other people should use the rope ladder to climb and descend. To stay in touch with the ship at all times, the skipper should carry a walkie-talkie.
5. Members of the boarding boat should maintain a low stirrups posture and avoid hooks touching their heads. Water rescue gear lifeboat must use the stop swing rope to hold on to the lifeline before leaving the ship, regardless of the weather.
6. When dangling the boat, all crew members must follow the orders of the commanders. It is strictly forbidden to pull the brake without authorization, use the crank handle and start the motor, and all actions should be closely coordinated.
7. When retrieving the boat, hook both the head and tail at the same time. The personnel accompanying the boat will board the boat once it has been raised to the boarding deck. No one is permitted to board the boat while it is moored on the davit. Tighten the davit wire rope and bind the boat rope firmly and steadily once the boat is in place.
8. When leaving the ship, boat rescue equipment must adhere to the norms and regulations for safe navigation, and the ship's duty officer should reinforce the lookout and contact, paying close attention to its dynamics.
When the lifeboat returns to the ship, it should be lifted quickly and the bottom plug opened to drain the water within the boat. In the cold season, the lifeboat's cooling water should also be released.
The release of lifeboats or rescue boats during navigation is a common method of rescuing people in the water, but it must be done in accordance with the relevant regulations and requirements to ensure the safety of the rescue personnel on board. Boat life saving equipment can be released according to the following requirements.
(1) If the sea is generally calm, the lifeboat should be lowered as soon as possible, and the boat's speed should not exceed 5 kilometers per hour when it is released.
(2) When launching the lifeboat, the ship should be slanted less than 10 degrees longitudinally and less than 20 degrees transversely, with a maximum speed of 5 knots. The ship can employ the halted manoeuvring approach to release the lifeboat in extreme weather. Stopping ropes, padding, and boats can be used to lessen and avoid the lifeboat swaying in severe waves and collisions with huge ships.
(3) The life saving equipment on board is at rest against the water when the boat is dropped to the surface. The bollard should be correctly secured before the hook is removed, and the hook should be removed at the same moment. If all of the hooks cannot be removed at the same time, the rear hooks should be removed first, followed by the front hooks.
(4) If the sea is rough, the boat should be pushed to the man overboard's upwind side and the downwind side lifeboat released.
(5) The lifeboat's approach to the man overboard is determined by relative drift speed, wind conditions, and the accident's circumstances.
a. Approaching people overboard from the downwind side.
b. If a fire breaks out on the distressed vessel, water rescue gear must be approached from the upwind side.
(6) When mooring with a ship in distress or between rafts, rope throwing guns and the necessary mooring lines should be available ahead of time.
(7) Persons in distress should be rescued from the side in the mid-ship area.
(8) When collecting boat life saving equipment in high winds and waves, the hook should be hooked before and after at the same time; if this is not possible, the front hook should be hung first, followed by the back hook. When the ship is swinging sideways from one side to the other, the hooking should be done.
