1.1 The purpose of a simplified voyage data recorder
(S-VDR) is to maintain a store, in a secure and retrievable form,
of information concerning the position, movement, physical status,
command and control of a vessel over the period leading up to and
following an incident having an impact thereon. Information contained
in a S-VDR should be made available to both the Administration and
the shipowner. This information is for use during any subsequent investigation
to identify the cause(s) of the incident.
