Davit-launched lifeboats

6.4.1 The unloaded lifeboat should be placed on blocks or suspended from the lifting hooks and sights should be erected for measuring keel sag. The measurements required in 6.4.4 should then be made.

6.4.2 The lifeboat should then be loaded with properly distributed weights to represent the fully equipped lifeboat loaded with the full complement of persons for which it is to be approved. The measurements required in 6.4.4 should again be made.

6.4.3 Additional weights should then be added so that the suspended load is 25%, 50%, 75% and 100% greater than the weight of the fully equipped and loaded lifeboat. In the case of metal lifeboats, the testing should stop at 25% overload. The weights for the various overload conditions should be distributed in proportion to the loading of the lifeboat in its service condition, but the weights used to represent the persons need not be placed 300 mm above the seatpan. Testing by filling the lifeboat with water should not be accepted as this method of loading does not give the proper distribution of weight. Machinery may be removed in order to avoid damage to it, in which case weights should be added to the lifeboat to compensate for the removal of such machinery. At each incremental overload, the measurements required in 6.4.4 should be made.

6.4.4 The following should be measured and recorded at each condition of load specified in 6.4.1 through 6.4.3:
.1 deflection of keel amidships;
.2 change in length as measured between the top of stem and stern posts;
.3 change in breadth over the gunwale at the quarter length forward, amidships and the quarter length aft; and
.4 change in depth measured from gunwale to keel.

6.4.5 The keel deflection and change in breadth in 6.4.4.1 and 6.4.4.3 should not exceed 1/400 of the lifeboat's length when the lifeboat is subjected to 25% overload; the results at 100% overload, if required by 6.4.3, should be approximately in proportion to those obtained at 25% overload.

6.4.6 The weights should then be removed and the dimensions of the lifeboat checked. No significant residual deflection should result. Any permanent deflection as a result of these tests should be recorded. If the lifeboat is made of GRP, such measurement should be taken after a lapse of time sufficient to permit the GRP to recover its original form (approximately 18 h).

Free-fall lifeboats

6.4.7 It should be demonstrated that the lifeboat has sufficient strength to withstand the forces acting upon it when loaded with a distributed mass equal to the mass of the number of persons for which it is to be approved and its equipment when free-fall launched from a height of 1.3 times the height for which it is to be approved. If the lifeboat is normally ramp-launched, and a ramp is not available, this test may be conducted by dropping the lifeboat vertically with the keel at the same angle that normally occurs during water entry.

6.4.8 After this test the lifeboat should be unloaded, cleaned and carefully examined to detect the position and extent of damage that may have occurred as a result of this test. An operational test should then be conducted in accordance with 6.11.1. After this test the lifeboat should again be unloaded, cleaned, and inspected for possible damage.

.1 have adequate frequency response for the test in which they are to be used but the frequency response should at least be in the range of 0 to 200 Hz;
.2 have adequate capacity for the acceleration forces that will occur during the tests;

6.18.2 Accelerometers should be placed in the lifeboat, parallel to the principal axes of the lifeboat, at those locations necessary to determine the worst occupant exposure to acceleration.

6.18.3 The accelerometers should be mounted on a rigid part of the interior of the lifeboat in a manner to minimize vibration and slipping.

6.18.4 A sufficient number of accelerometers should be used at each location at which acceleration forces are measured so that all likely acceleration forces at that location can be measured.

6.18.5 The selection, placement, and mounting of the accelerometers should be to the satisfaction of the Administration.

6.18.6 The measured acceleration forces may be recorded on magnetic media as either an analog or a digital signal or a paper plot of the acceleration signal may be produced.

6.18.7 If the acceleration forces are to be recorded and stored as a digital signal, the sampling rate should be at least 500 samples per second.

6.18.8 Whenever an analog acceleration signal is converted to a digital signal, the sampling rate should be at least 500 samples per second.

Evaluation with the dynamic response model

6.18.9 The dynamic response model is the preferred method to evaluate potential for the occupant in a lifeboat to be injured by exposure to acceleration forces. In the dynamic response model, the human body is idealized as a single-degree-of-freedom spring-mass acting in each co-ordinate direction as shown in figure 3. The response of the body mass relative to the seat support, which is excited by the measured accelerations, can be evaluated using a procedure acceptable to the Administration. The parameters to be used in the analysis are shown in table 1 for each co-ordinate direction.


Table 1 - Parameters of the dynamic response model

Co-ordinate axis	Natural frequency (rad/s)	Damping ratio
x	62.8	0.100
y	58.0	0.090
z	52.9	0.224

6.18.10 Before performing the dynamic response analysis, the measured accelerations should be oriented to the primary axes of the seat.

6.18.11 The desired outcome from the dynamic response analysis is the displacement time-history of the body mass relative to the seat support in each co-ordinate direction.

6.18.12 At all times, the following expression should be satisfied:


where d_x , d_y and d_z are the concurrent relative displacements of body mass with respect to the seat support, in the x, y and z body axes, as computed from the dynamic respose analysis and S_x , S_y and S_z are relative displacements which are presented in table 2 for the appropriate launch condition.

6.18.13 In lieu of the procedure in 6.18.9 to 6.18.12, the potential for an occupant in a lifeboat to become injured by an acceleration can be evaluated using the procedure presented in this section.

6.18.14 Before performing the SRSS analysis, the measured accelerations should be oriented to the primary axes of the seat.

6.18.15 Full-scale acceleration data should be filtered with no less than the equivalent of a 20 Hz low-pass filter. Any filtering procedure acceptable to the Administration may be used.

6.18.16 Acceleration data measured on a model should be filtered with a low-pass filter having a frequency not less than that obtained with the following expression:


where f_model is the frequency of the filter to be used, L_model is the length of the model lifeboat and L_prototype is the length of the prototype lifeboat.

8.1.1 For lifeboats other than free-fall lifeboats, davits and launching appliances, except the winch brakes, should be subjected to a static proof load of 2.2 times their maximum working load. With the load at the full outboard position, the load should be swung through an arc of approximately 10°C to each side of vertical in the intended fore and aft plane. The test should be done first in the upright position, followed by tests simulating a shipboard condition of list of 20°C both inboard and outboard. There should be no evidence of significant deformation or other damage as a result of this test. For free-fall lifeboats, the launching appliances for lowering a free-fall lifeboat by falls, except the winch brakes, should be subjected to a static proof load of 2.2 times the maximum working load at the full outboard position. There should be no evidence of significant deformation or other damage as a result of this test.

8.1.2 For lifeboats other than free-fall lifeboats, a mass equal to 1.1 times the maximum working load should be suspended from the lifting points with the launching appliance in the upright position. The load should be moved from the full inboard to the full outboard position using the means of operation that is used on the ship. The test should be repeated with the launching appliance positioned to simulate a combined 20°C inboard list and 10°C trim. All the tests should be repeated with a mass equal to that of a fully equipped lifeboat, without persons, or the lightest survival craft intended for use with the davit to ensure the satisfactory functioning of the davit under very light load conditions. The appliance should successfully lower the load under all of the conditions, and there should be no evidence of significant deformation or other damage as a result of the tests. for free- fall lifeboats, a mass equal to 1.1 times the maximum working load should be suspended from the lifting points. The load should be moved from the full inboard to the full outboard position using the means of operation that is to be used on the ship. The test should be repeated with a mass equal to that of the fully equipped lifeboat, without persons, to ensure the satisfactory functioning of the appliance under light load conditions. The appliance should successfully lower the load under both conditions and there should be no evidence of significant deformation or other damage as a result of the tests.

8.1.3 A mass equal to 1.1 times the maximum working load should be suspended from the lifting points with the launching appliance in the upright position. The load should be moved from the full inboard to the full outboard position using the means of operation that is used on the ship. The appliance should successfully move the maximum designed hoisting load from the outboard to the inboard position without causing permanent deformation or other damage.

8.1.4 Winch drums should be wound to the maximum number of tarns permitted and a static test load of 1.5 times the maximum working load should be applied and held by the brake. This load should then be lowered for at least one complete revolution of the barrel shaft. A test load of 1.1 times the maximum working load should then be lowered at maximum lowering speed through a distance of at least 3 m and stopped by applying the hand brake sharply. The test load should drop no more than 1m when the brake is applied. This test should be repeated a number of times. If the winch design incorporates an exposed brake, one of these tests should be carried out with the brake wetted, but in this case the stopping distance may be exceeded. The various tests should achieve a cumulative lowering distance of at least 150 m. Operation of the winch with a load of a mass equal to that of a fully equipped lifeboat, without persons, or the lightest survival craft intended for use with the winch, should also be demonstrated.

8.1.5 It should be demonstrated that a winch intended for use with a rescue boat is capable of recovering the rescue boat with the number of persons for which it is to be approved and its equipment or an equivalent mass at a rate of not less than 0.3 m/s.

8.1.6 The hand operation of the winch should be demonstrated. If the winch is designed for quick recovery by hand with no load, this should be demonstrated with a load of 1.5 times the mass of the empty lilting arrangements.*

8.1.7 Following completion of the tests the winch should be stripped for inspection. These tests and the inspection should normally be witnessed by a representative of the Administration.

6.2.2 Each release hook should be statically proof tested to 2.5 times the safe working load and do provided with an approved testing establishment certificate certifying that it has been so tested.

Operational test

6.2.3 Each release hook should be submitted to an operational test with a mass equivalent to the safe working load being applied. The release arrangements should be demonstrated and checked with the liferaft loaded to ensure that the automatic release hook will not release while the load is still applied.

Marking

6.2.4 Each release hook should be checked to ensure it is permanently marked with:
.1 the manufacturer's name or the approved name of the release hook;
.2 the date of manufacture;
.3 the safe working load:
.4 the number of the test certificate required by 6.2.2; and
.5 clear, concise operating instructions.

Lowering test

6.2.5 One liferaft ballasted to represent a 10% overload or an equivalent mass should be lowered from each launching appliance to establish the rate of lowering. The 10% overload should be 10% of the mass of the liferaft assembly together with its equipment and full complement of persons calculated at 75 kg per person. It should be jerked to ensure that the liferaft launching appliance, its fastenings and the supporting structures can withstand the associated loads.

Recording of lowering test

6.2.6 The time should be recorded for the sequence of preparing, loading and launching three liferafts. If so desired, persons may be used only in the preparing and loading operations and ballast substituted for the lowering and launching part of the test. This sequence test need not be carried out on every launching appliance on a ship. However, at least one example of each launching appliance type and arrangement should be so tested on each ship.

Towing strain test

6.2.7 A moderate towing strain should be put on the liferaft when waterborne to check that the release arrangements are satisfactory under this condition.
