after that go through model diagram 70

where you will see the bus bar

then connect your generator

we are now in model diagram number 70

this is the electric power plant

you can see here the shaft generator

this is the main engine

we have the dg1 or d cell generator

number one

this is the generator engine we have the

dg2

or diesel generator number two this

is the generator engine dg1 and dg2 are

exactly the same

so how you start diesel generator one is

exactly the same

with how you start d cell generator

number two

we also have here toolbox generator or

tg this is the turbine

and we have the eg or emergency

generator

it has the smallest engine

now here is the main bus bar

and we have here the emergency bus bar

the power to the emergency bus bar

is being supplied by emergency generator

now let's go to d cell generator number

one

if you have started the engine of diesel

generator number one

then these circles should turn yellow

just like the emergency generator

it is yellow since the emergency

generator engine is running

so assuming that this circle is now

yellow check for the output voltage

there should be a 440 volts output

if you do not see a 440 volts output

go down to voltage control and click on

then the output voltage will appear here

if you see the 440 volts you can now

connect the

diesel generator 1 to the main bus bar

how do you connect dg1 to the main bus

bar

go to the upper right corner you can see

here dg1 dg2

shaft generator and turbo generator

select dg1 click this button

and observe if the ready indicator light

turns green

if it turns green it means that dg1 is

now ready to be connected to the main

bus bar

so click connect if you click this

connect button this breaker

will connect

the next action is to get the load of

the emergency generator

and transfer it to generator number one

meaning this breaker connecting

emergency generator and the emergency

bus bar

should be transferred here how do you

transfer this breaker from emergency

generator to here

go to this breaker and click breaker in

this will connect and this will

automatically jump here

now the load of the emergency generator

is removed and transferred to the

generator number one

however during this transition

when this breaker transfers here

the supply power to the auxiliary sea

water pump is cut

off so you need to go to the auxiliary

sea water pump

and restart otherwise

diesel generator number one will lose

cooling and trip

so let's go to the auxiliary sea water

pump

in process directory zero one

zero one is the seawater system

to the auxiliary sea water pump and

restart the pump the pump will restart

and the power is

being supplied now by generator number

one

after starting the auxiliary pump

proceed in model diagram number 71 and

number 72

and supply power to the other consumers

so go to process directory

model diagram 71 this is the main

switchboard starters

and number 72 is main switch board

feeders

go first to 71

and these are the consumers

in order to supply power to the

consumers

this button must be clicked in

right now all the buttons are clicked in

next

go to 72 which is the continuation of

model diagram 71

and you will find here more consumers

click all the buttons in

these consumers above are 440 volts

while these below are 220 volts

now to have a 220 volt supply

we have another transformer this is the

main transformer

you need to connect the transformer by

clicking in

it should be connected like this now you

have a 220 volt supply

then pick all the buttons in

to supply power to the 220 volts

these are the lights

and the panel boards when you have

supplied power to the consumers

you can now go ahead and start the

equipment that you need

for example we need to start the

air ventilation to the engine room

[Music]

so we go to process directory

number 40 this is the air ventilation

system

we have here the engine room supply

funds

we have number one number two number

three number four

click them start

[Music]

we have purifier room fun see which room

fun we also have your

engine room exhaust fans we have four

two three and four we have the

accommodation fans

number one and two engine control room

fan

cargo control room fan

click the buttons to start now we need

to put the generator into

priority one automatic so go to panel

directory generator control

101 power chief generator control

we have here the shaft generator diesel

generator 1

diesel generator 2 and turbo generator

go to diesel generator 1

check that the ready indicator light is

lighting green

which means the generator is ready to be

put to auto

so click priority one and click

automatic

in case the ready button is not lighting

green then you cannot put the generator

to automatic

so what you should do is go back to 75

this is the diesel generator one

and check whether the preheater is in

auto

and the priming pump is in auto

and the engine control is in remote

control

check also if there is an alarm you need

to rectify the alarm

then go back to panel directory 101

generator control

[Music]

101 power chief generator control

and check if the ready button is now

lighting green

if so then click priority 1

and click auto

that's it gentlemen you have watched how

to prepare the decel generator one

how to connect it to the bus bar how to

supply power to the consumers

and finally how to set it to priority

one automatic
