According to SOLAS we have to lower the disposable fall lifeboat the following
Every 3 several weeks
Every 3 several weeks we are able to lower the lifeboat either by free fall launching or by secondary way of launching. If lowering by free fall, the needed crew have to sit within the boat and launch it from the inside.
Otherwise, we are able to lower the disposable fall lifeboat to water by davit. Crew may then board the lifeboat by embarkation ladder.
Regardless of the way we lower the boat, we have to manoeuver it in water every three several weeks. We have to test the engine and watering during manoeuvring.
Every 6 several weeks
If you’re decreasing the boat every 3 several weeks by free fall means, there’s not one other factor you must do every 180 day. However if you simply had decreased the boat by secondary means for example davit, you have to lower the boat by free fall every 6 several weeks. Or execute simulated launching provided lifeboat has got the provisions for your.
Ok now what will it mean by “simulated launching” from the free fall boat ?
Simulated launching replaces the advantages of decreasing the lifeboat by free fall method. Whenever we lower the lifeboat by free fall method, we’re testing the discharge mechanism from the lifeboat. Simulated launching does same but without decreasing the lifeboat with free fall.
In simple words, the motorboats which are fitted with simulated launching includes a securing wire. One finish of the wire is linked to boat along with other around the ship structure. Once the boat is guaranteed, this wire is going to be loose without any weight onto it.
One crew will operate the discharge gear from the boat. When the boat releases, after moving slight distance, simulation wire holds the boat. This test will make certain the release mechanism is working.
After simulation test, the boat then have to be decreased with davit and manoevered in water.
Maintenance needed on free fall lifeboats
Maintenance by Ship staff
Every company includes a weekly and monthly listing for lifeboat which we must follow. But at the very least, we ought to do following maintenance on free fall lifeboat.
It’s good practice to check on lifeboat shell for just about any cracks during drills. We have to repair any crack within the shell at the same time.
Lifeboat All-in-one air support system
Lifeboats fitted on tankers has all-in-one air support system. This really is to keep positive pressure within the lifeboat in situation of abandoning the ship in toxic atmosphere.
Positive pressure inside lifeboat helps to ensure that toxic gases don’t find its way inside lifeboat.
Each month we ought to look into the pressure from the air bottles. Pressure of every bottle shouldn’t be under 10% from the working pressure of bottle.
Usually you will find three air bottles within the lifeboat. When examining the pressures, we ought to look into the pressure in every bottle. When you are performing so for that second bottle, make certain to shut the valves in the first bottle. You also should release pressure in the line before opening the 2nd bottle valve.
When I pointed out, we have to test the watering during maneuvering from the lifeboat. As well as that each month we have to check and operate the sprinkler valve. This really is to make sure that the valve isn’t frozen so we can open/close it easily.
Each time, sprinkler is tested with ocean water, it’s good practice to purge the lines with freshwater.
We have to make sure run the lifeboat engine each week not less than 3 minutes (SOLAS Chapter III, Reg 20.6.3).
When the ship is buying and selling in cold temperature, you should see if the fuel for lifeboat engine is appropriate of these conditions.
Every five years, we have to either alter the fuel oil or send the fuel for analysis. As lifeboat fuel quantity isn’t considerable, renewing the fuel every 5 year is a lot economical option.
Lifeboat battery supplies power for lighting and for beginning the lifeboat engine.
We must make certain that battery can begin the lifeboat engine multiple occasions. A lot of companies possess a policy to resume the lifeboat battery every two or three years.
As one of the top providers of free fall lifeboat test kit and related products in Singapore Aaron Marine Offshore is a reputed company. It has at least 20 years’ experience in products such as lifeboats, rescue boats, and launching appliances.
