GENERAL NOTES

1. THIS DRAWING PROVIDES THE CONFIGURATION OF THE SHIP'S ELECTRICAL

POWER SYSTEM FOR THE NOAA SHIP NANCY FOSTER AND WAS DEVELOPED

UNDER TAR SSI-021 (02) BASED ON REFERENCE NO. 1 AND A SHIPCHECK

CONDUCTED AT CASCADE GENERAL, INC. IN PORTLAND, OREGON ON OCTOBER

28-30, 2002, FOLLOWING THE DEMILITARIZATION AND CONVERSION OF THE

EX-USNV AGATE PASS (YTT -12) TO A NOAA RESEARCH VESSEL.

2. ALL MATERIAL AND WORKMANSHIP SHALL CONFORM TO APPLICABLE

REGULATIONS OF THE UNITED STATES COAST GUARD (USCG), 46CFR,

SUBCHAPTER U, OCEANOGRAPHIC RESEARCH VESSELS; AMERICAN BUREAU OF

SHIPPING (ABS) RULES FOR BUILDING AND CLASSING STEEL VESSELS, 2000

EDITION; AND REGULATIONS PRESCRIBED IN THE INTERNATIONAL MARITIME

ORGANIZATION (IMO) SAFETY OF LIFE AT SEA (SOLAS), 2000 EDITION.

3. TWO GENERATORS WILL NORMALLY BE ON-LINE AND ONE GENERATOR IN

STAND-BY. THREE GENERATORS MAY BE ON-LINE SIMULTANEOUSLY FOR A

SHORT DURATION ONLY. SHOULD THREE GENERATORS BE ON-LINE FOR 30

SECONDS, AN ALARM WILL SOUND (VCMS SYSTEM). SHOULD THREE

GENERATORS BE ON-LINE FOR ONE MINUTE, THE LAST GENERATOR ON-LINE

WILL BE AUTOMATICALLY TRIPPED OFF-LINE.

4. GENERATOR CONDENSATE HEATERS ARE ENERGIZED VIA AUXILIARY CONTACTS

ON THE RESPECTIVE GENERATOR CIRCUIT BREAKER THAT ARE CLOSED WHEN

THE CIRCUIT BREAKER IS OPEN.

5. UV TRIPS ON MAIN SWITCHBOARD CIRCUIT BREAKERS SHALL BE INDIVIDUALLY

FUSED.

6. WHEREVER POSSIBLE, INSTALL NEW 480VAC AND 120VAC CABLES IN EXISTING

DESIGNATED CABLEWAYS. CABLES OF THE VESSEL CONTROL & MONITORING

SYSTEM (VCMS) SHALL BE TREATED AS SENSITIVE TO RFI AND EMI, AND SHALL

NOT BE ROUTED THROUGH CABLEWAYS CONTAINING 480VAC AND/OR 120VAC

POWER AND LIGHTING CABLES. VCMS CABLES SHALL BE SEGREGATED FROM

ALL AC CABLES BY A MINIMUM OF 6 INCHES EXCEPT WHERE THEY CROSS AT

RIGHT ANGLES. VCMS CABLES SHALL NOT BE INSTALLED IN ANY CABLEWAY

CONTAINING JAMMING CABLES SUCH AS RADIO ANTENNA, RADAR MODULATING

TRANSMIT/RECEIVE CABLES OR WAVEGUIDE, OR DEPTH SOUNDER TRANSDUCER

CABLES. VCMS CABLES HSALL BE SEGREGATED BY A MINIMUM OF 24 INCHES

FROM ALL JAMMING CABLES.

7. THIS DRAWING, IN CONJUNCTION WITH THE 120VAC PANEL SCHEDULE

REFERENCE 5, SUPERSEDES REFERENCE 1, 3 AND 7.
