Updated Final Safety Analysis Report – (STS-004-002)2.4.2 Fire Detection and Alarm System (FA)The installed FA system is multi-loop, Class A computerized and programmable. It is approved by theU.S. Coast Guard, NFPA, and UL for marine use. The FA System is powered by a 120VAC powersource via a 120/120VAC isolation breaker. The isolation breaker will prevent power spikes fromdamaging the Alarm Panel internal components.It consists of 130 smoke detectors and 50 pull boxes throughout the ship, which will activate stroberepeaters with alarm warnings and pre-recorded spoken directions. This alarm system notifies a remotemonitoring station that will alert the local fire department.In accordance with NFPA 72, Fire Safety Codes, a speaker microphone is located at the Alarm panel andspeaker strobes are located throughout the normally occupied positions of the ship.2.5 Lifesaving EquipmentAll of the life-saving equipment is deactivated, disabled and performs no active function. A limitednumber of life rings are located on the ship.2.6 Radio EquipmentAll of the radio equipment is deactivated, disabled and performs no active function.2.7 Deck MachineryMost of the principal deck machinery including lifeboat davits and boat winches are deactivated, disabledand performs no active function. The hydraulic anchor windlasses are operable and can be used to lowerand raise the anchors which are made up with the anchor chains. The forward mooring capstans arepresently disabled, but can be reactivated with minimum effort, if required.2.8 Flooding AlarmsThe flooding alarm system is installed and maintained in accordance with standard marine practices fordeactivated ships. The ship has flood alarm sensors that will detect flooding in any compartment adjacentto the sea. The ship’s flood detectors alarm at a continuously manned monitoring center as described inSection2.11. The detectors also alarm visibly and audibly at the ship.2.9 Dehumidification SystemThe dehumidification (DH) system is out of service and partially dismantled. It was installed in 1994following the ship being placed in protective storage at the James River Reserve Fleet, Ft. Eustis, VA.The DH system is an interior preservation system commonly employed by MARAD on vessels in longterm(multi-year or indefinite) retention. A DH system mechanically lowers the moisture content of theatmosphere of an enclosed area of a ship to arrest deterioration. Per the MARAD Reserve Fleet Manual,the acceptable range for relative humidity is 35% to 45%. DH systems are typically temporary in nature,to permit rapid removal in the event of a vessel reactivation. Vent ducting and cabling associated with theDH system is normally routed through doorways, passageways and ladders throughout ship, leading toobstruction of the same.The DH system was deenergized after the crew was established and the ship was routinely mannedfollowing the end of the Colonna’s Shipyard period in 2007. The crew is expected to note and take actionto correct degradation that the DH system would have minimized in an unmanned ship. The DHductwork was removed and stored for potential future re-use. The DH machinery has been relocated andinstalled in locations that do not obstruct routine vessel operations, in anticipation of possible futureRev. VI 22
Updated Final Safety Analysis Report – (STS-004-002)reactivation. Permanent cabling is provided to power the DH machinery. The DH system will bereactivated if the ship is moved to a periodically unattended state.2.10 Hull Cathodic Protection SystemThe vessel is equipped with a conventional, marine impressed current cathodic protection system for hullpreservation. The system is monitored and maintained as required. It is operated in accordance withstandard maritime practices. At times, the system may be supplemented by external cathodic protectionas described in the Reserve Fleet Manual.2.11 Security SystemsThe ship is served by two separate sensing and alarm systems. The first system includes numerousintrusion, flooding, and fire sensors. The second system includes an intrusion sensor per TechnicalSpecifications as well as a smaller number of flooding and heat detectors. Alarms are transmitted to theoff-site monitoring stations (a separate station for each system), which is then responsible for contactingdesignated NSS personnel. In addition, a fire alarm on the first system will activate internal strobes, anaudible alarm, and a recorded warning; these annunciators are installed throughout the normally occupiedareas of the ship.2.11.1 Camera Surveillance SystemA Camera Surveillance System is installed to allow video monitoring of the ship internal andexternal areas.2.11.2 Security Entrance DoorThe normal entrance to the ship is operated by a key fob by activating entry and exit panels. The foboperates to communicate with the door closure via a reader pad using passive radio identificationfrequency. After opening the door closure ensures the door returns to the closed position. In anemergency, the door can be opened from the inside by an emergency override switch panel. Thesystem records the date and time that the individual holding the fob enters and exits the ship.2.12 General AlarmThe General Alarm System was returned to service after repair and testing. The system is powered by abattery/trickle charger located in the C-Deck Battery Room. The General Alarm is activated by a Manualactivation switch in Stateroom A-18.Rev. VI 23
