4.1.2 Each
of the two objectives has a series of Rule requirements attributed
to them, these Rules are arranged in a ‘top-down’ manner
such that an objective is stated as the highest level requirement.
At the next level, a goal, or series of goals, are detailed; the goals
are then developed as performance requirements; and ultimately specified
guidance where applicable.
4.1.3 In general,
a system is to be compliant with the SOLAS - International Convention for the Safety of Life at Sea convention;
however where this cannot be achieved, the performance criteria, goals
and objectives are to be satisfied by assignment of a Concession or
through the application of an Alternative Design Justification Report, see the Naval Survey Guidance. The referenced SOLAS - International Convention for the Safety of Life at Sea Regulations to satisfy different Goals are
provided for guidance purposes. Alternative standards consistent with
the overall SOLAS philosophy can be applied where the compliance with
the Objective can be demonstrated to an equivalent level as those
in SOLAS.
4.1.4 The
escape routes are to be designed so as to support escape of all personnel
to a designated place of safety. Where a pre-determined time for escape
is specified in the Design Disclosure, based on the design and operational
role of the ship then it is to be validated by full-scale trials or
by a simulation acceptable to LR and the Naval Administration.
