DESIGN OF FREE FALL LIFEBOATS
|Publication Date:||1 April 2009|
Scope and application
This standard applies to free fall lifeboat systems and their launching appliances.
The standard applies to the design, materials, fabrication, testing, operation, repair and requalification of free fall lifeboats and their launching appliances.
This standard is not applicable to design of an evacuation system as a whole. This limitation reflects that free fall lifeboats and their launching appliances constitute only parts of an evacuation system. Lifeboats and their launching appliances must be compatible with and have interface to escape routes, muster stations, communication systems, power supply systems, lighting and other features of the host facility which are not covered by this standard.
This standard is not applicable to design of davitlaunched lifeboats.
This limitation reflects the difference between free fall lifeboats and davit-launched lifeboats, e.g. when it comes to loads and modes of operation.
This standard is not applicable to design of lifeboats on host facilities located in waters where sea ice or sea floes occur.
