Annex 1
Performance standards for the systems and services to remain operational on passenger ships for safe return to port after a casualty
General
- These performance standards provide additional guidance for the uniform implementation of SOLAS regulations II-2/21.4 and II-2/21.5.1.2, which require that, after a fire or flooding casualty, as defined in regulations II-1/8-1 and II-2/21.3, basic services be provided to all persons on board and that certain systems remain operational for safe return to port.
Propulsion systems and their necessary auxiliaries and control systems
- Propulsion machinery and auxiliary machinery essential for the propulsion of the ship should remain operable.
Ship’s electrical-generation systems and their auxiliaries vital to the vessel’s survivability and safety
- Electrical power should be available and sustainable for all essential services specified in SOLAS regulations II-2/21.4 and II-2/21.5.1.2, with due regard to such services as may be operated simultaneously. The application of regulation II-2/21.4 requires that other systems (e.g., engine-room ventilation, lighting of spaces outside safe areas not affected by the casualty, etc.) remain operational to support the functionalities listed therein.
Steering systems and steering-control systems
- Steering systems and steering-control systems should be capable of manoeuvring the ship.
Systems for fill, transfer and service of fuel oil
- Systems for internal fill transfer and service of fuel oil should be capable of fuel transfer to
active propulsion and power generation equipment.
Internal communications system
- Internal communications should be achieved by any effective portable or fixed means of
communications.
External communications
- The ship should be capable of communicating via the GMDSS or the VHF Marine and Air
Band distress frequencies even if the main GMDSS equipment is lost.
Fire main system
- The fire main should remain operational in all main vertical zones not directly affected by the casualty. Water for fire-fighting purposes should be available to all areas of the ship.
Fixed fire-extinguishing systems (gaseous and water)
- The automatic sprinkler system or any other fixed fire-extinguishing system designed to protect an entire space should be operational in all spaces not directly affected by the casualty.
Fire and smoke detection systems
- The fire detection system should remain operational in all spaces not directly affected by the
casualty.
Bilge and ballast systems
- The bilge pumping systems and all associated equipment essential for its operation should be available in all spaces not directly affected by the casualty.
Navigation systems
- Equipment essential for navigation, position fixing and detection of risk of collision should be available. The ship should be capable of displaying the proper light configuration in compliance with the International Regulations for Preventing Collisions at Sea in force.
Basic services to safe areas
- The basic services specified in SOLAS regulation II-2/21.5.1.2 should be available to all safe areas, as defined in SOLAS regulation II-2/3.51.
Flooding detection system
- The flooding detection system should remain operational after a casualty.
Other systems vital to damage control efforts
- This includes any system that the Administration determines is vital to damage control
pertaining to fire or flooding.
