The Tier I goals are as defined in SOLAS regulation II-1/3-10
and are reproduced here for ease of reference, as follows:
-
Ships shall be designed and constructed for a specified
design life to be safe and environmentally friendly, when properly
operated and maintained under the specified operating and environmental
conditions, in intact and specified damage conditions, throughout
their life.
-
.1
Safe and environmentally friendly means
the ship shall have adequate strength, integrity and stability to
minimize the risk of loss of the ship or pollution to the marine environment
due to structural failure, including collapse, resulting in flooding
or loss of watertight integrity.
-
.2
Environmentally friendly also
includes the ship being constructed of materials for environmentally
acceptable recycling.
-
.3
Safety also includes the ship's
structure, fittings and arrangements providing for safe access, escape,
inspection and proper maintenance and facilitating safe operation.
-
.4
Specified operating and environmental
conditions are defined by the intended operating area for the
ship throughout its life and cover the conditions, including intermediate
conditions, arising from cargo and ballast operations in port, waterways
and at sea.
-
.5
Specified design life is the nominal
period that the ship is assumed to be exposed to operating and/or
environmental conditions and/or the corrosive environment and is used
for selecting appropriate ship design parameters. However, the ship's
actual service life may be longer or shorter depending on the actual
operating conditions and maintenance of the ship throughout its life
cycle.
