fun 4b
A/E overhauling prechecks compressor safeties and why NRV on discharge side why bursting disc and if burst, bursting disc material why brake on purifier and lots of cross question fun 5 generator principle and cross question single phase motor types of fuses and location how to test fuses battery testing and safeties starter routines and cross question fun 6 machineries overhauled on board fuel injector over hauling nd test centrifugal pp overhauling nd clearance if no spare wear ring spare on board then(he given sleeve machining nd all) ref charging nd purging nd some more |
Safety..
Hopper tanks const.. Margin plate.. Transverse section of bulk carrier.. Regulation about safety of bulkhead.. Angle of loll.. Gm and gz.. stability affected by hopper tanks.. Metacentric height and show GZ.. Righting lever.. How it works.. Motor and MEP Combined Exhaust valve.. stuked in cross questioning. Draw exhaust valve.. Explain.. Pulse and constant pressure turbo.. Differentiate the two.. in deep.. Explain why i cant use pulse on me.. Valve overlap.. Some other questions too.. i forgot.. Electrical.. PID.. where is it used.. and on off switch.. where is it used.. Star delta starter used where.. and what happens to voltage and current.. Trickd me by mixing with auto transformer.. Alternators protections.. how each of them is tested |

Fun 3
Q GRT,NRT,displacement Q why tanker less freeboard compare to bulk carrier Q metacenter,righting lever Q simpsons rule Q explain ISPS & ISM Fun 4b & 6 Q diff b/w 2 stroke and 4 stroke Q M.E lub oil system Q T/C surging & cause Q high exh temp n one unit Q bumping clearance Q scum blowdown Q centrifugal inspection Fun 5 Q emg.power supply Q alternator safety Q reverse power trip Q battery room panel How much power produced onboard? How much voltage? How many generators? How much voltage for lightings? Why cant we use 220 volts motors and use 220 voltage thro out? How are we getting 220 volts? Principle of transformer? Unlike motors is the coil moving to cut the flux? Then how is the emf induced? I said the current is alternating and it cuts the stationary coil which in turn cuts the magnetic flux inducing emf! |
Function 3:
Starts with ship particulars Isolation valve in fire line ship is in angle of loll condition what will happen if it further heel ows discharge criteria light ship displacement reserve buoyancy Function 4b: Starts with Main engine nomenclature what is the indication for fuel pump roller reversing turbo charger surging. cross questions exhaust gas temperature for one unit increase reasons. cross questions angular bearing how axial vibrations in purifier is nullified Function 5: draw full wave bridge rectifier ckt diagram explain what r the things u see in steering gear motor panel * wat type of ship &wat engine u had. * wat is the difference in Manouring with RT-FLEX & MAN B&W. * how wil u know if one unit is not reversed while starting. * safeties in steering gear. * relief valve lifting pressure in it. * what is the minimum weight of life buoy on bridge wing. * tel me the off load release mechanism of life boat. |
Fun-4:
1.Which ship u sailed and what is the MCR? 2.What is Superlong stroke &howz it significant than earlier type engines? 3.How,where& why expansion line is provided in m.e jacket cooling water line? 4.Reefer compressor HP cut-out happens. What corrective action will u take to rectify it and how u will report it to second engineer? 5.Starting sequence of boiler? 6.How L.O reaches Main bearing? (I have no idea what he meant by this question) 7.Working of M.E L.O backflush filter Fun-5: 1.Alternator specification 2.What is reverse power? How reverse power works?(Atleast a dozen of cross questions) 3.How three phase is converted into single phase. 4.What r all the voltages in the ship. Fun-6: 1.How will u take peak pressure in a generator running idle. 2.What type of pressure gauge is used in peak pressure indicator. 3.A/E crankshaft deflection. |
