Contractors in HV space (a CP can take up to 6 contractors in a HV space as long as they aren’t working direct on HV equipment)
How are ME ‘important’ keys controlled
By the LETOW, they hold the keys to the key tanks in the SCC
How do we operate the ‘Man below’ routine
Pegging in on the ‘peg-in’ board located in the SCC
What is the access & door policy for HV compartments
A CP can work in a HV space but not on HV equipment
A CP can take up to 6 contractors in a HV space as long as they aren’t working directly on HV equipment
Define HV Live
Capable of producing
Are producing
Or Connected to shore supply
Define HV Safe
Ship has been disconnected
decay times have elapsed
Isolations and earths are in place
Define HV Dead
Ship in no longer capable of receiving/producing HV
All Circuit Main Earths (CME) have been applied
Gas Monitors
Atmospherics for fridges/FWD & AFT Engine room
4X - monitors for refrigerant and methane leaks
5X - can monitor the same as a 4X but is used to monitor for exhaust gases
Diesel Generators locations and power output
4 Main DG’s
2 FWD(G) - 8.7MW
2 AFT(M) - 11.3MW
HV Shore supply
Connected when alongside in harbour via a Caucestac boom, this follows the tide to allow more/less cable to create the slack arch between the ship and shoreside
Things you check when conducting rounds on shore supply
Slack arch from the cauastac boom
Hotspots (visual checks)
Fire/flood dangers
Arc-ing between cables
Insulation isn’t damaged
DG watch keeping checks
-Lub oil checks (60•)
-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)
How a DG works (4 stroke cycle)
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)
DG HVSBD’s
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
What is ‘Decay Time’
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
How many LVSBD’s are there and their Locations
13 LVSBD’s as well as a emergency one
Located in:
6C
6G
6M
6P
5L
6U
What the Emergency Switchboard does
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

Safety devices on the HVSBD’S
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
Things to check on the HVSBD
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
Entering a HVSBD procedure at sea
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.
How many SSTX’s and what they do
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
How many hanger boost Pp’s and their locations
3 Hanger Boost Pp’s
3K PORT
3L STBD
3R STBD
What is the HV Golden rules
D - Disconnect
I - Isolate
E - Earth
C - Cordon
P - Prove Dead
R - Release Paperwork
Describe Induction
- Inlet valve open, exhaust valve closed
- Piston moves from TDC to BDC drawing
in new air.
Describe Compression
- 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
Describe Combustion
- Both inlet and exhaust valves closed
- Fuel ignites within combustion chamber
forcing the piston from TDC to BDC
Describe Exhaust
- Inlet valve closed, exhaust valve open
- Piston moves from BDC to TDC forcing
spent gases out the chamber and out the
exhaust manifold
Describe Valve Overlap
- 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

First shot is automatic, supports life and brings oxygen down to 12.5%
Second shot requires Captains permission as it doesn’t support life, it brings oxygen lvls down to 10% and also takes away fire fighting capabilities
