Annual Thorough Examination: Lifeboats.The following items should be examined and checked for satisfactory condition and operation:.
1 condition of lifeboat structure including fixed and loose equipment;.
2 engine and propulsion system;.
3 sprinkler system, where fitted;.
4 air supply system, where fitted;.
5 manoeuvring system;.
6 power supply system; and.
7 bailing system. 9

Release gear
The following should be examined for satisfactory condition and operation after the annual winch brake test with the empty boat:.
1 operation of devices for activation of release gear;.
2 excessive free play (tolerances);.
3 hydrostatic interlock system, where fitted;.
4 cables for control and release; and.
5 hook fastening.

Release gear operational test of on-load release function.
1 position the lifeboat partially into the water such that the mass of the boat is substantially supported by the falls and the hydro static interlock system, where fitted, is not triggered;.
2 operate the on-load release gear;.
3 reset the on-load release gear; and
.4 examine the release gear and hook fastening to ensure that the hook is completely reset and no damage has occurred.

Release gear operational test of off-load release function.
1 position the lifeboat fully waterborne;
.2 operate the off-load release gear;.
3 reset the on-load release gear; and.
4 recover the lifeboat to the stowed position and prepare for operational readiness.



Davit The following items should be examined for satisfactory condition and operation:.
1 davit structure, in particular with regard to corrosion, misalignments, deformations and excessive free play;.
2 wires and sheaves, possible damages such as kinks and corrosion;.
3 lubrication of wires, sheaves and moving parts;.
4 functioning of limit switches;.
5 stored power systems; and.
6 hydraulic systems.
Annual Thorough Examination: Winch The following items should be examined for satisfactory condition and operation:
.1 open and inspect brake mechanism;.2 replace brake pads, if necessary;.3 remote control system;.4 power supply system; and.5 winch foundation.

 Dynamic Winch Brake Test1 Annual operational testing should preferably be done by lowering the empty boat. When the boat has reached its maximum lowering speed and before the boat enters the water, the brake should be abruptly applied. 15
16. Dynamic Winch Brake Test2 The five-year operational test should be done by lowering the boat loaded to a proof load equal to 1.1 times the weight of the survival craft or rescue boat and its full complement of persons and equipment, or equivalent load. When the boat has reached its maximum lowering speed and before the boat enters the water, the brake should be abruptly applied.3 Following these tests, the brake pads and stressed structural parts should be re-inspected. 16
17. Overhaul of on-load release gear Overhaul of on-load release gear includes:.1 dismantling of hook release units;.2 examination with regard to tolerances and design requirements;.3 adjustment of release gear system after assembly;.4 operational test as per above and with a load according to SOLAS regulation III/20.11.2.3;and.5 examination of vital parts with regard to defects and cracks

Importantly dont forget to mention FPD and Recovery strap maintenance and to replace every five years.
