Thisdocumentisintendedtogivedetailsandguidancetoaboatbuilderorequipmentinstallertoinstall

theSeakeeper,Inc.Model5500StabilizingGyro.Thegyroiscapableofproducingloadsupto14.7kN

(3300lbs.)oneachfoundationsaddleandcarefulconsiderationshouldbegiventofoundationdesignto

insureitiscapableoftransferringtheseloadsintothehull.Itisassumedthatpersonnelinvolvedin

installationarefamiliarwithGRPstructuresaswellastheuseofhighstrengthadhesivesthatwillbe

usedtobondthegyrotothehullstructure.Theinstallershouldreviewthefollowinglistofdrawingsto

1.1Precautions

Gyroflywheelissupportedbyprecisionbearings.Makecertainwhileunpackingandliftinggyro

assemblytoNOTdroporimpartmechanicalshockasdamagetobearingscouldresult.

Whilehandling/installinggyroassembly,protectexposedhydraulicbrakecylinderrods(See

Figure1)fromscratchesordamageasthiscouldleadtoprematuresealfailureandoilleaks.

Whilehandling/installinggyroassembly,donotallowelectricalfittingsthatexitbottomofgyro

enclosuretocomeincontactwithanysurfaceorobjectasthiscoulddamagethefittingsand

potentiallyaffectthevacuumintegrityoftheenclosure.

Exercisecaretoprotectgyropaintedfinishasdamagetofinishcouldleadtoearlyappearance

degradationofinstalledgyro.



DoNOTremoveforwardbrace(seeFigure1).



1.2SelectionofGyroInstallationLocation

Selectionofmountinglocationofgyroshouldconsiderthefollowingdesirablefeatures:

Thegyromustbeinstalledaftofamidshipstominimizehigh

accelerationloadingsduetohull/waveimpactsduringoperationat

highspeedorinlargewaves.

Overheadaccessorsufficientclearanceforremoval/re‐installationofgyroenclosurefor

overhaulinfutureyears.



Gyroshouldbeinstalledinadryspacetominimizeeffectsofcorrosion.



Clearanceforreplacementofgimbalanglesensorongyroportside(seeFigure2).



Clearanceforfilling/purgingbrakehydraulicoil(seeFigure2).



Clearanceforfillingwater/glycolcoolingcircuit(seeFigure2).



Clearanceforreplacementofbrakehydrauliccylinders(seeFigure2).



Spaceforrecommendedsound/safetyenclosure.

RefertoFigure3forrecommendedclearancestotransversebeams.Ifatransversebeamislocated

undertheforwardbrace,itmustbe3”(76mm)fromtheedgeofthesaddlebeamstoprovidethe

SafetyEnclosure



Thereisalargetorqueaboutthegimbalaxiswhenthegyroisprecessing.Therefore,thegyro

mustbehousedinanenclosureoracompartmentorinstalledinacagesopersonnelorgear

cannotcomeintocontactwiththegyrowhileitisprecessing.

Thegyroshouldbetreatedwiththesamerespectonegivesahighspeedrotatingpropeller

shaftorengineshaft.



Noise/Soundproofing/Ventilation

Gyronoisehasbeenmeasuredundersteadystateconditions(nowaveload)inSeakeeper'slabandin

our43fttestboat.Thesteadystatenoiseistypicallyintherangeof70‐75dBunweighted.Asthe

frequenciesemittingthehighestsoundpressuresarelow(likeothermarinemachinery),itis

recommendedthatthegyrobeinstalledinacageinamachineryspacethatisalreadytreatedwith

soundproofing.

Ifthegyrostabilizerhastobelocatedoutsideamachineryspace,itshouldbeinstalledinasound

dampingenclosuretopreventlowfrequencynoise(approximately133Hz)fromenteringtheliving

spaces. Inthiscase,theenclosurecanbeopenatthebottombetweenthehullstringers. Asmall

exhaustfanshouldbeinstalledinthetopoftheenclosuretopullambientairthrutheenclosuresothe

airintheenclosuredoesnotheatup.Thiswillensurethattheownerdoesnotgetnuisanceshutdowns

duetotheMotorDriveandBearingtemperaturealarmsinsomeoperatingconditions(highambientair

temperature,highseawatertemperature,highseastate,etc).

Thefanshoulddeliveraminimumof35cuft/min(60cum/hr)whichshouldexchangetheairinthe

enclosureaboutonceperminute.Small,massproduced,axialandcentrifugalcoolingfansareavailable

witheitherACorDCinputpower,ballbearings,extendedtemperaturerange,lownoiseratings,long

MTBF,marinized,etc.Locatetheinletatthebottomoftheenclosureandmountthefanatthetopas

anexhaustfan.Acentrifugalfanmaybebesttominimizeoutletarea.Thefanpowerrequirements

wouldtypicallybeintherangeof20watts. WhenusingaDCfan,wireittothesamebreakerthat

providespowertotheGyroControlBoxsothefanturnsonandoffatthesametimeasthecontroller.

1.3UnpackingCrate

1) ReferenceSeakeeperDrawingNo.90212,Model5500HardwareScopeofSupplyforitemsthat

shipwiththegyro.

2) Removeelectricalcomponents,cables,andmisc.itemsandsetaside.

3) Removepackingmaterialsthatsecuregyroassemblyinsidethecrate.

4) Attachspreaderbartothetwoliftingeyeslocatedonthetopofthegyroenclosure.Alsoattach

alevelinglinethatconnectsspreaderbartobrakegimbalshaft.Gyroweighs485kg(1069lbs).
