1、Designation:F 1756 97a(Reapproved 2002)An American National StandardStandard Guide forImplementation of a Fleet Management System Network1This standard is issued under the fixed designation F 1756;the number immediately following the designation indicates the year oforiginal adoption or,in the case
2、of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide provides an overview and guide for theselection and implementation by shipowners and op
3、erators of aFleet Management System(FMS)network of computer ser-vices in a client/server architecture(see Fig.1).The FMS isbased upon a wide area enterprise network consisting of anunspecified number of Shipboard Information TechnologyPlatforms(SITPs)and one or more shoreside Land-BasedInformation T
4、echnology Platforms(LITPs),which providesmanagement services for the shipping enterprise.The FMS canbe understood as a computer system comprised of one or moreLITPs and one or more SITPs.It can be characterized asmission critical 24 3 365(24 h/day,365 days/year).1.2 The SITP(see Fig.1)provides a set
5、 of softwareservices,including:1.2.1 Communications Services,to communicate betweenvessels and with shore via multiple wireless communicationtechnologies;1.2.2 Data Acquisition Services,providing access to ship-board system data as required for use by other systems andmanagement purposes;and,1.2.3 E
6、xecutive Services,providing software process admin-istration and control.1.2.4 In total,the SITP provides the capability for multipleshipboard computer systems to share data with each other andto communicate with shore-based management or other vesselsor both.1.3 The SITP is understood to consist of
7、 integrated hard-ware,software,a data repository,and standardized procedures,which provide the ability to send,receive,process,transfer,and store data or messages in digital form in a common modefrom shipboard systems or administrative utilities or both,andfrom designated sources outside the network
8、,for example,systems accessed through wireless communication services,such as satellite,VHF,HF,and so forth.Shipboard systemsinclude navigational,machinery control and monitoring,cargocontrol,communications,and so forth.The SITP also willprovide the capability for the remote administration andmainte
9、nance of associated computer systems aboard the vessel.1.4 The SITP requires an underlying hardware and networkinfrastructure,including a shipboard computer local area net-work(LAN),file servers,workstations,wireless communica-tions transceivers,cabling,other electronic and optical devices,video dis
10、play units,keyboards,and so forth.1.5 The SITP also requires underlying system softwareproviding network operating system(NOS)services,DBMSservices,and other system software.1.6 There also is a layer of shipboard application systems,which are designed to capitalize on the FMS infrastructure toshare
11、data with other shipboard systems and managementashore.Those systems also would be able to capitalize on theremote management capabilities of the FMS.1.7 The LITP is an asset that can exchange operating andadministrative data from individual ships and maintain aDBMS to support fleet management and o
12、ther maritimeapplications.The LITP will support data repositories,fileservers,workstations or personal computers(PCs),and acommunication hub providing connectivity to distributed sat-ellite services,VHF(very high frequency),HF/MF(highfrequency/medium frequency),and land lines.The DBMSmakes possible
13、the development of knowledge-based“decisionaids”by providing the ability to retrieve,process,and analyzeoperational data.1.8 This guide does not purport to address all the require-ments for a SITP,which forms a path for data for direct controlof the operation or condition of the vessel or the vessel
