Lifeboat accidents resulting in fatalities and serious injuries are all too frequent, despite efforts in recent

years to reduce them.

Most of the accidents happen in boats using conventional davits and on-load release systems.

Real Life Accident: Rescue Boat Falls In Water During Drill With Crew Members Inside, One Dies

By MARS Reports | In: Case Studies | Last Updated on July 21, 2016The crew of a large vessel was conducting a routine launching drill of a rescue boat in port. As the craft was coming up to its normal stowage position, a proximity sensor/limit or cut-off switch arrangement (Figure 1) that was designed to cut electrical power to the winch motor failed to operate correctly. The rescue boat and its four crew fell 29 meters into the water. One of the boat’s crew died and two were hospitalised.

FREE-FALL LIFEBOAT

FREE FALL LIFEBOATเรอชวยชวตแบบปลอยเลอนลงอสระ

movie : FREE-FALL LIFEBOAT launching (1min.)

FREE-FALL LIFEBOAT - Maintenance

As per SOLAS we need to lower the free fall lifeboat as followsEvery 3 monthsEvery 3 months we can lower the lifeboat either by free fall launching or by secondary means of launching.

Every 6 monthsIf you are lowering the boat every 3 months by free fall means, there is no other thing you need to do every 6 month. But if you had lowered the boat by secondary means such as davit, you need to lower the boat by free fall every 6 months. Or you can carry out simulated launching provided lifeboat has the provisions for that. After simulation test, the boat then need to be lowered with davit and manoevered in water.

Lifeboat hullLifeboat Self contained air support systemEvery month we should check the pressure of the air bottles. The pressure of each bottle should not be less than 10% of the working pressure of bottle.

Usually there are three air bottles in the lifeboat. When checking the pressures, we should check the pressure in each bottle. When doing so for the second bottle, make sure to close the valves from the first bottle. Also you should release pressure from the line before opening the second bottle valve.

FREE-FALL LIFEBOAT - Maintenance

Sprinkler systemAs I mentioned, we need to test the sprinkler system during maneuvering of the lifeboat. Apart from that every month we need to check and operate the sprinkler valve. This is to ensure that the valve is not frozen and we can open/close it easily.Every time, sprinkler is tested with sea water, it is good practice to flush the lines with fresh water.

Lifeboat EngineWe need to test and run the lifeboat engine every week for at least 3 minutes (SOLAS Chapter III, Reg 20.6.3).If the ship is trading in cold weather, it is important to check if the fuel for lifeboat engine is suitable for these conditions.Every 5 years, we need to either change the fuel oil or send the fuel for analysis. As lifeboat fuel quantity is not considerable, renewing the fuel every 5 year is much economical option.

Lifeboat batteryWe have to make sure that battery can start the lifeboat engine multiple times. Many companies have a policy to renew the lifeboat battery every 2 or 3 years.

CASE STUDY : Improper Reset Launches Freefall Lifeboat Accidentally

5 days before the incident, the second engineer was involved with multiple checks of the lifeboat release hook operation. During these checks, he noticed that the hydraulic system was low on oil and he topped it up. He also noted that the activation of the hook release required between 10 and 15 operations of the hydraulic pump handle.

On 1 March 2014, with this knowledge in mind, the second engineer entered the lifeboat to satisfy himself that all was in readiness for any possible upcoming port state inspection. He noted the oil level was low in the release pump and topped it up. He then pressurized the system to see if he could locate any leaks. He operated the pump 3 or 4 times, well short of the 10 to 15 pumps he believed it normally took to release the hook, but the hook unexpectedly released.

Concerns have arisen regarding the dangers of a hydraulic ram not being properly reset after use in Chinese-made JX-4 release mechanisms from Jiangsu Jiaoyan Marine Equipment Company after a freefall lifeboat launched during a maintenance inspection seriously injuring the occupant. Simulations wires which should have restrained the lifeboat and prevented the launch also failed below their safe working load and are being investigated

Case study of Free-fall lifeboat incident !!

Inspection of the

lifeboat, its release

mechanism and analysis

of the available evidence

showed that the

actuating cylinder ram

did not always retract

fully into the cylinder

without some external

force being applied.

Furthermore, it was

found that the hook

stopper block could be

repositioned sufficiently

to engage the hook and

prevent it opening

without the actuating

cylinder ram being fully

retracted. In such cases,

with the hook reset, the

hydraulic pump

recirculation valve could

be closed trapping the

system in this position

It is likely that this is what happened when the lifeboat release system was reset following the tests in Singapore. Then, on 1 March, the second engineer only had to operate the pump handle three or four times for the actuating cylinder ram to move far enough to release the stopper block and the hook.

In such circumstances, the release hook could be activated with a reduced number of operations of the hydraulic pump because the actuating cylinder ram had less distance to travel before it released the stopper block and the hook.

Before entry into the lifeboat to carry out maintenance and procedures which list the checks that are to be made prior to any lifeboat maintenance being carried out have been implemented. Further, the master’s permission is now required before the lifeboat release system hand pumps are operated.

years of their service lives, and thereafter at the frequency required by SOLAS regulation III/20.8.1.1.

This 10-year limitation may be extended if real time verification justifies acceptance by the

Administration;

2. inspected on board by inspection personnel in accordance with the provisions of these

Guidelines and the instructions of the manufacturer at intervals not exceeding 12 months from the

last service or onboard inspection and for the first 10 years of their service life;.

GUIDELINES FOR THE APPROVAL OF INFLATABLE LIFERAFTS SUBJECT TO EXTENDED SERVICE INTERVALS NOT EXCEEDING 30 MONTHS

4. GENERAL

5.4.7 Cold inflation test

Following the damp heat cyclic test, two liferafts should be subjected to a cold inflation test in accordance with

paragraph 5.17.5 of Part 1 of the Revised recommendation (resolution MSC.81(70)).

5.4.8 Pressure test

The liferafts should be subjected to the test described in paragraphs 5.17.7 and 5.17.8 of Part 1 of the

Revised recommendation (resolution MSC.81(70)).

5.4.9 Floor seam test

The liferafts should be subjected to the floor seam test described in paragraph 5.9 of the Recommendation on

conditions for the approval of servicing stations for inflatable liferaft (resolution A.761(18), as amended by

resolution MSC.55(66)).

5.4.10 Detailed inspection

Liferafts which have been subjected to the above specified tests, and have been found to comply with the

acceptance criteria, should then be subjected to a thorough visual inspection in order to reveal any damage,

wearing or chafing which may have been imposed by the previous tests.

5. TESTING

6. SERVICING AND INSPECTION PROCEDURES

6.1.4 Provisions should be available at the servicing station to ensure that the relative humidity behind the

protective barrier of the liferaft approved for extended service intervals will not exceed a relative humidity of 65%

rH at 20ºC when the liferaft has been serviced and repacked.

6.1.5 Items of equipment should be checked to ensure that all are in good condition and dated items should be

replaced in cases where the expiry date falls before the next service date of the liferaft if they cannot be replaced

in due course in conjunction with an intermediate periodic onboard inspection.

6.1.6 Davit-launched liferafts approved for extended service intervals should be subjected to a 10% overload

suspension test at intervals not exceeding 30 months.

6.1.7 Liferafts approved for extended service intervals should be serviced at the intervals specified in 4.1.1.

Tests as described in appendix 2 to resolution A.761(18) should be applied thereafter.

6.1.8 Procedures as described in the appendix should be established to ensure that each gas cylinder is

properly filled and gastight before fitting to a liferaft.

APPENDIX

CONTROL OF GAS CYLINDERS

(see 6.1.8)

1 All gas cylinders should be weighed and checked against the gross mass which has been marked

on the bottle. To allow for difference of scales when check-weighing, a tolerance of 14 g should be

permitted. No gas cylinder should be fitted unless it has passed one of the following two tests:

.1 A storage period of at least 30 days after filling. Weighing should take place before and after

storage using the same scales. There should be no loss of weight.

.2 The leak test specified in paragraph 2.

2. This paragraph describes a leak test for CO2 cylinders which is regarded as

equivalent to weighing the filled cylinder before and after at least 30 days of storage.

การตรวจสอบถง CO2

1. Materials required

1. Polythene bags of a suitable size to fit over the head of the cylinder, e.g.:

for a 125 mm diameter cylinder the bag size is approximately 230 mm open width x 300 mm length;

for a 100 mm diameter cylinder the bag size is approximately 165 mm open width x 300 mm length;

for a 90 mm diameter cylinder the bag size is approximately 150 mm open width x 300 mm length.

2. Elastic bands of a suitable size.

3. A measuring glass, capacity 25 ml.

2. Test solution

• The test liquid should be the standard test solution used to indicate small amounts of CO2 gases

(0.004N sodium carbonate in a 2% weight/volume solution of phenolphthalein).

• The solution should be stored in a cool place in dark coloured glass bottles with a tight-fitting screw

cap. The shelf life should not exceed 12 months.

LEAK TEST FOR CO2 CYL.

3 Method of testing

1. Lay the cylinder to be tested on its side in a rack, such that the valve end is protruding. Make sure the valve

and shoulder of the cylinder are free from dust and other contaminants by carefully wiping it with a clean, dry

cloth. Remove the dust cap to clean the valve, then replace the cap loosely.

.2 Using the measuring glass, transfer 25 ml of the test solution into a polythene bag.

.3 Pass the open end of the bag over the valve head and attach it to the cylinder body using one or more elastic

bands. Make sure there are no air gaps in the seal.

.4 The polythene bag should hang 20 cm off the valve end of the cylinder with the test solution in one corner.

.5 Maintain the test for a period of not less than one hour.

.6 After the period of time stated in 2.3.5, shake the solution gently and make the observations detailed in 2.4.

.7 A control sample is necessary to detect any contamination. The sample is made by pouring 25 ml of test

solution into a bag which is not fitted to a cylinder, but is sealed at the open end with adhesive tape to exclude

atmospheric contamination. This bag should be placed on the rack in the vicinity of the cylinders being tested.

LEAK TEST FOR CO2 CYL.

.4 Observations

.1 A leak of carbon dioxide from the cylinder will cause the pink colour of the test solution to fade. The

test solution will become clear as water.

.2 If no colour change is observed, there is no leak of gas from the cylinder.

.3 The control sample should not change colour during the test. If a colour change takes place, this

indicates that the atmosphere in the test area is contaminated with carbon dioxide and tests carried out together

with this control sample are invalid. Tests should be repeated after corrective action has been taken on the

atmosphere.
