4.4.6.7. All lifeboats shall be designed with due regard to the safety of persons in the water and the possibility of damage to the propulsion system by floating debris. the number of persons with an average mass of 75 kg, all of whom may wear lifejackets and sit in a normal position without affecting the means of propulsion or the operation of the lifeboat equipment; or any lifeboat with lateral openings in the vicinity of the firing range shall have a freeboard measured from the waterline to the lowest orifice through which the lifeboat can be invaded, of at least 1.5 per cent of the length of the lifeboat or 100 mm, whichever is greater; and There are different types of lifeboats used on board a vessel depending on the type of vessel and other special requirements. Not all lifeboats have the same type of trigger mechanisms, as starting a lifeboat depends on several other factors. In this article, we will examine the main types of lifeboat release mechanisms and learn more about SOLAS requirements for lifeboats. at least the distance between 1.3 m and 1.7 m determined by linear interpolation for a lifeboat that can accommodate nine to 24 people. (7) Two painters capable of a length at least twice the distance between the towing position of the lifeboat and the waterline in the lightest airworthiness conditions or 15 m, whichever is greater. On lifeboats, which are launched in free fall, the two painters must be stowed near the bow ready for use. In the case of other lifeboats, one painter attached to the required release device and release mechanism shall be attached to the forward end of the lifeboat and the other to the other firmly attached to the bow of the lifeboat or in the vicinity of the operational lifeboat.

Each lifeboat must be equipped with a device for securing a painter near its bow. The device shall be so designed that the lifeboat does not exhibit dangerous or unstable characteristics when towed by the vessel moving in calm waters at speeds of up to 5 knots. 2.2 A laden release capability that releases the lifeboat with a load on the hook. This clearance shall be so arranged that the lifeboat is released, under all loading conditions, from the lifeboat not loaded on the water at a load of 1.1 times the total mass of the lifeboat when loaded with all its crew of persons and equipment. This rejection capacity must be adequately protected against accidental or premature use. Adequate protection shall include, in addition to a danger signal, special mechanical protection which is not normally required for discharge. To avoid accidental release during the rescue of the vessel, the mechanical protection (locking) should only be activated when the release mechanism is correctly and completely reset. In order to avoid premature release of the load, the operation of the trigger mechanism charge should require conscious and sustained operator intervention. The release mechanism shall be designed in such a way that the crew of the lifeboat can clearly observe when the release mechanism is correctly and completely reset and ready to be lifted.

A clear instruction manual should be accompanied by an appropriately worded warning; 4.4.7.11. A manually operated light or light source capable of being lit for at least 12 hours shall be installed inside the lifeboat so that the survival instructions and equipment instructions can be read. However, oil lamps are not allowed for this purpose. How to overtake people who perform a release test on board the lifeboat when it is on trailers. Are the trailers 100% safe? And what do you think if we add an extra chain block during testing? 4.4.6.4. The engine shall be operational when the lifeboat is invaded to the centreline of the crankshaft. 4.4.7.3. In addition to proximity to the rudder and propeller, appropriate handles shall be provided or a floating lifeline shall be installed around the outside of the lifeboat above the waterline and within reach of a person in the water. According to the LSA and SOLAS codes, there are a number of requirements that ensure safety on a lifeboat. These requirements are as follows: A lifeboat alone is enough to get people to a safe place, but there are some basic life safety equipment that every boat should carry.

Here is a list of these equipment: This type of mechanism releases lifeboats once the boat is completely at sea. At the bottom, there is a hydrostatic piston unit connected to the control lever. Once in the water, the water pressure moves the lever upwards, releasing the drop wire. The engine shall be equipped with either a manual starting system or a power start system with two independent rechargeable energy sources. Any necessary start-up assistance must also be provided. Engine starting systems and engine starting devices shall start the engine within 2 minutes of starting at an ambient temperature of -15°C, unless the administration considers that a different temperature is appropriate, taking into account the particular voyages on which the lifeboat is constantly used. Starting systems must not be obstructed by crankcases, seats or other obstacles. The speed of a lifeboat when travelling in calm water, when loaded with all its crew of persons and equipment and with all motorized auxiliaries, shall be at least 6 knots and at least 2 knots when a 25-person life raft is loaded with all its crew of persons and equipment or equivalent. A sufficient quantity of fuel suitable for the full temperature range provided in the ship`s area of operation shall be provided to allow the fully loaded lifeboat to operate at 6 knots for a period of at least 24 hours. New technologies for modern lifeboats are now very important for all sea voyages, but now many ships carry lifeboats with old systems.

For this reason, it is necessary to modernize not only the new lifeboats, but also the old lifeboats. specifically. Equipment, radio systems (SOLAS) and so on. Having addressed the issues of lifeboats and their trigger mechanisms, let`s consider what standards must be met when using the above. 3) The following must be present in the lifeboat (the most important are mentioned here) Enclosed lifeboats are surrounded by a roof that protects people inside from rain, sea water currents and strong winds. These boats, when overturned, stand by themselves. These are further divided into fully enclosed lifeboats and partially enclosed lifeboats. HII has a question about where it is mentioned in SOLAS or other IMO publications or guidelines, the standard length of lifeboats drops many tanks In addition, remember the LSA code requirement for cargo release mechanisms, which require every lifeboat, including lifeboats, which are also lifeboats, or equipped with hooks with a load release capability. The exceptions are free-falling lifeboats. The requirement has been met and the compliance date has expired (no later than July 1, 2019).

IMO requirements for pressure relief systems in accordance with IMO Resolution 320(89). In addition to these three common types, there are two other advanced types of lifeboats, namely fire-retardant lifeboats and hyperbaric lifeboats. Regardless of the type of lifeboat, the most important consideration is to ensure that it is released quickly and perfectly to help people in distress as quickly as possible. Therefore, there are three different types of boat release mechanisms. Where a single drop and hook system is used to stack a lifeboat or rescue boat in combination with a suitable painter, the requirements of paragraph 4.4.7.6.2. In such an arrangement, a single ability to release the lifeboat or lifeboat only when it is fully on the water is sufficient. The number of persons allowed to be accommodated by a lifeboat intended to be launched by fall shall be the lesser of the following: any lifeboat launched in the event of a fall or fall, with the exception of a free-falling lifeboat, shall be equipped with an unlocking mechanism arranged in such a way that all hooks are released simultaneously and the opening control must be clearly indicated in only one colour; that stands out from its environment. The loading mechanism can detach the lifeboat from the wire, with the vessel above water level and all crew members in the vessel.

The cargo will still be in autumn, because the boat would not have touched the water. Normally, the release of the load is activated when the boat is about to touch the surface of the water, so that the fall is smooth without damaging the boat and harming the crew inside.
