2 FWD(G) - 8.7MW
2 AFT(M) - 11.3MW

33
Q

Hotspots (visual checks)
Fire/flood dangers
Arc-ing between cables
Insulation isn’t damaged

35
Q

DG watch keeping checks

-HT & LT (60 & 40)
-Governor sight glass
-Oil mist detector - reads 1 only and everything else is green
-Oil levels via Dipstick
-Unusual noises, smells, vibrations
-Oil/fuel leaks
-7bar fuel pressure
-Duplex strainer diff pressure (0.4bar)

36
Q

How a DG works (4 stroke cycle)

A

Induction - inlet open, Ex Vv shut, Piston is TDC, fresh air cools cylinder

Compression - inlet & Ex Vv shut, Piston moves to TDC, compresses Fresh air, hot cylinder

Combustion - Measured atomised fuel injected & combustion in the hot pressured air

Exhaust - Ex Vv opens, piston moves to TDC pushing Ex gasses out - Vv overlap at TDC (both Vv open) cools cylinder & allows for charging

The Vv’s on the cylinders operate via the rocker arms that are connected to the cam shaft

Alternator is on the drive end of the DG, it drives the shaft, rotating the rotor that induces EMF into the stator(windings & magnets) In terms of the alternator produces electrical power from mechanical movement ( Kinetic Energy)

37
Q

DG HVSBD’s

A

Receive 11,000v 3phase 60Hz from DG’s
4 HVSBD’s - 2 FWD & 2 AFT
HVSBD’s have red & yellow hashings around the compartment entrances
All HV spaces have; red and yellow hashings at the entrance, decay times, Signs of death and HV Kill Cards

38
Q

What is ‘Decay Time’

A

Decay times allow you to know how much time should have to pass before being allowed to enter a compartment as it’ll be rendered as safe to do so once the time has elapsed

39
Q

How many LVSBD’s are there and their Locations

A

13 LVSBD’s as well as a emergency one

Located in:
6C
6G
6M
6P
5L
6U

40
Q

What the Emergency Switchboard does

A

The emergency switchboard is powered from 5.1 LVSBD if not it will automatically try 5.2 if both fail the EDG will start within 45seconds to power the Emergency Switchboard

Emergency Switchboard feeds:
5 zones, 4 edc in each zone
4 intermediate HPSW Pp’s
3 hanger boost Pp’s (3K port, 3L, 3R STBD)
2 Submersible Pp’s
1 Emergency Generator

These are the direct supplies Indirectly from the 4th powered EDC in each zone, things like the 4 auxiliaries for the DG’s

41

44
Q

Rover FWD Engine Room

A

Running Checks
Leaks (fuel, oil, water)
Tripped Equipment
Alarms
Atmospherics
SW Pp’s (Running/not & for leaks)

45
Q

Safety devices on the HVSBD’S

A

Harmonic filters - on 3 of 4 to pick up harmonic feedback from the prop motors, HVSBD 2 doesn’t need one as it isn’t directly connected to a PM

All the HVSBD’s have VCB’s - a circuit breaker that disconnects the busbars via a vacuum to stop any arc-ing

46
Q

Things to check on the HVSBD

A

Micron Units -
Any alarms/faults if so record the fault then book, book clear the LCP
If the fault comes back, notify part of ship

47
Q

Entering a HVSBD procedure at sea

A

Check entrance for signs of heat & use the back of your hand to feel the heat of the entrance. If contempt, slightly open and have a quick scan of the area then pin the door back. Do a figure of 8 checking the compartment before inviting others in.

48
Q

How many SSTX’s and what they do

A

13 SSTX’s to match 13 LVSBD’s

The SSTX’s alarm at 60•c and trip at 65•c

HVSBD’s feed 11,000v into the SSTX’s and they step it down to 440v to supply the LVSBD’s

49
Q

How many hanger boost Pp’s and their locations

A

3 Hanger Boost Pp’s
3K PORT
3L STBD
3R STBD

50
Q

E - Earth
C - Cordon
P - Prove Dead
R - Release Paperwork

51
Q

Describe Induction

A
  • Inlet valve open, exhaust valve closed
  • Piston moves from TDC to BDC drawing
    in new air.
52
Q

Describe Compression

A
  • Both inlet and exhaust valves closed
  • Piston moves from BDC to TDC
    compressing and heating the air within
    the cylinder
  • Just before TDC fuel is injected (to allow
    for ignition delay) into the hot
    compressed air within the chamber
53
Q

Describe Combustion

A
  • Both inlet and exhaust valves closed
  • Fuel ignites within combustion chamber
    forcing the piston from TDC to BDC
54
Q

Describe Exhaust

A
  • Inlet valve closed, exhaust valve open
  • Piston moves from BDC to TDC forcing
    spent gases out the chamber and out the
    exhaust manifold
55
Q

Describe Valve Overlap

A
  • inlet valve open, exhaust valve open
  • Drawing in new air across the top of the
    cylinder and exhaust valve to aid cooling
  • This process also aids in cylinder purging

Q

Inergen Shots

A
