Share your knowledge by writing answers to the question Ask or answer a question. I keep saying lifting the boat on lifenoat basis of release gear example I mentioned earlier.
After simulation test, the boat then need to be lowered with davit and manoevered in water.

For this, shore engineer just lowers the lifeboat with the davit to perform this test. This is because, opening of hydraulic brake decreases rather than increases the reliability of the brake.
If by ERD you mean Emergency recovery Device called recovery stropes then it is Nylon straps used for recovery of on lifdboat release lifeboat in heavy weather. SOLAS want us to try to lower by free fall every 3 months But if it is not possible for some reasons, it allows us to lower the lifeboat with davit and then manoeuvre once every 3 months but it must be lowered by free fall atleast every 6 months.
Crew can then board the lifeboat by embarkation ladder. And the main reason for that is ease of use and ease of maintenance. But if we combine this fact with the fact that most of the companies do not allow fredfall vessels to stay at anchor if wind force is more than 6, the stopper should not deform.
What if, there is leakage in the hydraulic system. Free fall lifeboat holds onto a hook and this hook is released by hydraulic pressure generated from the hand pump inside the lifeboat. As I had said, the problem with chain resting on the stopper is that in high wind force, the stopper can deform creefall in emergency we may not be able to pick up the anchor.
