1974年国际海上人命安全公约1988年11月（GMDSS）修正案（二）

d， at intervals not exceeding 12 months，when the ship is not at sea.

　　[ One method of checking the capacity of an accumulator battery isto fully discharge and recharge the battery， using normal operatingcurrent and period （e.g. 10 hours）。 Assessment of the charge condition canbe made at any time， but it should be done without significant dischargeof t

he battery when the ship is at sea.]

　　7 The siting and installation of accumulator batteries which provide areserve source of energy shall be such as to ensure：

　　。1 the highest degree of service；

　　。2 a reasonable lifetime；

　　。3 reasonable safety；

　　。4 that battery temperatures remain within the manufacturer'sspecifications whether under charge or idle； and

　　。5 that when fully charged， the batteries will provide at leastthe minimum required hours of operation under all weather conditions.

　　8 If an uninterrupted input of information from the ship'snavigational or other equipment to a radio installation required by thischapter is needed to ensure its proper performance， means shall beprovided to ensure the continuous supply of such information in the eventof failure of the ship's main or emergency source of electrical power.

　　Regulation 14 Performance standards

　　1 All equipment to which this chapter applies shall be of a typeapproved by the Administration. Subject to paragraph 2， such equipmentshall conform to appropriate performance standards not inferior to thoseadopted by the Organization.

　　[ Reference is made to the following performance standards adopted bythe Organization by the resolutions indicated：

　　。1 Narrow-band direct-printing telegraph equipment for thereception of navigational and meteorological warnings and urgentinformation to ships （Assembly resolution A.525 （13））。

　　。2 General requirements for Shipborne radio equipment forming partof the future global maritime distress and safety system （Assemblyresolution A.569 （14））。

　　。3 Ship earth stations capable of two-way communications （Assemblyresolution A.608 （15））。

　　。4 Shipborne VHF radio installation capable of voice communicationand digital selective calling （Assembly resolution A. 609 （15））。

　　。5 Shipborne MF radio installations capable of voice communicationand digital selective calling （Assembly resolution A. 610 （15））。

　　。6 Shipborne MF/HF radio installations capable of voicecommunication， narrow-band direct printing and digital selective calling（Assembly resolution A.613 （15））。

　　。7 Float-free satellite emergency position-indicating radiobeacons operating on 406 MHz （Assembly resolution A.611 （15））。

　　。8 Survival craft radar transponders for use in search and rescueoperations （Assembly resolution A.604 （15））。

　　。9 Float-free VHF emergency position-indicating radio beacons（Assembly resolution A.612 （15））。

　　。10 INMARSAT standard-C ship earth stations capable oftransmitting and receiving direct-printing communications （Assemblyresolution A.663 （16））。

　　。11 Enhanced group call equipment （Assembly resolution A.664（16））。

　　。12 Float-free satellite emergency position-indicating radiobeacons operating through the geostationary INMARSAT satellite system on1.6 GHz （Assembly resolution A.661 （16））。

　　。13 Float-free release and activation arrangements for emergencyradio equipment （Assembly resolution A.662 （16））。]

　　2 Equipment installed prior to the dates or application by prescribedregulation 1 may be exempted from full compliance with the appropriateperformance standards at the discretion of the Administration， providedthat the equipment is compatible with equipment complying with theperformance standards， having due regard to the criteria which theOrganization may adopt in connection with such standards.

　　Regulation 15 Maintenance requirements

　　1 Equipment shall be so designed that the main units can be replacedreadily， without elaborate recalibration or readjustment.

　　2 Where applicable， equipment shall be so constructed and installedthat it is readily accessible for inspection and on-board maintenancepurposes.

　　3 Adequate information shall be provided to enable the equipment to beproperly operated and maintained， tanking into accoun

t the recommendationsof the Organization.

　　[ Reference is made to the recommendation of general requirements forShipborne radio equipment forming part of the future global maritimedistress and safety system （resolution A.569 （14））。]

　　4 Adequate tools and spares shall be provided to enable the equipmentto be maintained.

　　5 The Administration shall ensure that radio equipment required bythis chapter is maintained to provide the availability of the functionalrequirements specified in regulation 4 and to meet the recommendedperformance standards of such equipment.

　　6 On ships engaged on voyages in sea areas A1 and A2， the availabilityshall be ensured by using such methods as duplication of equipment，shore-based maintenance or at-sea electronic maintenance capability， or acombination of these， as may be approved by the Administration.

　　7 On ships engaged on voyages in sea areas A3 and A4， the availabilityshall be ensured by using a combination of at least two methods such asduplication of equipment， shore-based maintenance or at-sea electronicmaintenance capability， as may be approved by the Administration， takinginto account the recommendations of the Organization.

　　8 While all reasonable steps shall be taken to maintain the equipmentin efficient working order to ensure compliance with all the functionalrequirements specified in regulation 4， malfunction of the equipment forproviding the general radiocommunications required by regulation 4.8 shallnot be considered as making a ship unseaworthy or as a reason for delayingthe ship in ports where repair facilities are not readily available，provided the ship is capable of performing all distress and safetyfunctions.

　　Regulation 16 Radio personnel

　　Every ship shall carry personnel qualified for distress and safetyradiocommunication purposes to the satisfaction of the Administration. Thepersonnel shall be holders of certificates specified in the RadioRegulations as appropriate， any one of whom shall be designated to haveprimary responsibility for radiocommunications during distress incidents.

　　Regulation 17 Radio records

　　A record shall be kept， to the satisfaction of the Administration andas required by the Radio Regulations， of all incidents connected with theradiocommunication service which appear to be of importance to safety oflife at sea.“

　　CHAPTER V SAFETY OF NAVIGATION

　　Regulation 12 Shipborne navigational equipment
