DNV DNVGL-ST-E406 PDF

Scope and application

The standard applies to the design, materials, fabrication, testing, operation, repair and requalification of free-fall lifeboats and their launching appliances.

The standard is not applicable to the design of an evacuation system as a whole. This limitation reflects that free-fall lifeboats and their launching appliances only constitute parts of an evacuation system.

Lifeboats and their launching appliances shall be compatible with and have an interface with escape routes, muster stations, communication systems, power supply systems, lighting and other features of the host facility which are not covered by this standard.

The standard is not applicable to the design of davit-launched lifeboats.

Guidance note:

This limitation reflects the difference between free-fall lifeboats and davit-launched lifeboats, e.g. when it comes to loads and modes of operation.

The standard is not applicable to the design of lifeboats on host facilities located in waters where sea ice or ice floes occur.

The standard is not part of the technical basis for DNV GL classification or maritime statutory compliance services. Governmental legislation may stipulate requirements differing from the provisions of this standard.
