Increase of life & rescue boat occupants weight from 75 kg to 82.5 kg
The assumed mass of occupants of life boats and rescue boats is to be increased from 75 kg to 82.5 kg for vessels with keel laid on or after 1 July 2010 according with MSC 272(85).
The requirements apply as follows:
- Cargo ship lifeboats (both davit launched and free-fall) should be approved assuming an average mass of occupants of 82.5kg (increased from 75kg).
- Cargo and passenger ship rescue boats should be approved assuming an average mass of occupants of 82.5kg (increased from 75kg).
- Cargo ship free-fall lifeboat seating arrangements should comply with amended LSA Code Chapter IV, paragraph 4.7.2.
When installing new equipment on board vessels with a keel laying date before July 2010, clear guidance on the application of Resolution MSC 272(85) should be provided by the Flag Administration.
Testing / Survey requirements
During 5 year load testing of life boat and rescue boat launching appliances the above increase to the weight of the occupants should be applied.
Load test is performed with 1.1 times the total weight of the boat including equipment and all passengers. So in your calculation you should multiply the total amount of life boat passengers, as stated in form E of safety equipment certificate, by 82.5 kg add the weight of life boat and equipment and add 10% more.
