Appendix 2

 This appendix provides examples, one for hierarchical layered structure and one high-level only, both in compliance with these guidelines. These examples may be further developed.

Area: SOLAS chapter III

Example for layers of functional requirements

High-level generic functional requirements

  • .1 Information: provide necessary information of conditions both within and surrounding the ship during an emergency.

  • .2 Communication: ensure necessary means of communicating emergency and distress, communication to SAR organizations and indication of the ship's position.

  • .3 Escape: provide means of safe escape to the assembly/muster stations.

  • .4 Evacuation from ships: provide a safe means of evacuation for passengers and/or crew from the assembly/muster stations to a survival craft and ensure safety of their lives at sea.

Specific functional requirements

Description Rationale Expected performance
Survival Place

Provide a safe place protecting all people (crew + passengers) from a ship in distress until rescue

Fire & explosion and loss of floatability of vessel endanger persons on board and require a place for survival until rescue - Safe even if vessel sinks

- Safe in case of fire on vessel

- Protection for anticipated time of rescue (set by regulator?)

Protect Against Environment

Provide means to protect people in distress against (extreme) environmental conditions

High/low temperature, strong wind, animals etc. can endanger people by the hazards hypothermia, heat stroke etc. - A habitable environment is provided protecting people against anticipated temperatures, wind, sun radiation, …
Prevent Drowning

Provide means to enable survival in water until rescue

 Persons in water are endangered by drowning and hypothermia. Means are provided to

- prevent drowning of persons (unconscious, awake) in water

- enable/support rescue from water?
Life Sustainment

Provide means for life-sustainment

 Persons in distress are endangered by starvation, die of thirst or injuries.

Persons on board are endangered by consequences of injuries.

Means are provided to

- sufficiently supply people with water

- sufficiently supply people with calories

- allow first medical aid for injuries

- all provided for anticipated time of rescue

Area: SOLAS chapter II-2

High-level generic functional requirements

Description Rationale Expected performance
Containment and extinction of any fire in the space of origin Fire & explosion endanger persons on board. Mitigate the possibility spread of fire - Contain fire in fire zone of origin for given time

- Contain fire by passive and/or active means

- Provide means to extinguish fire
