All the ship's loads have to be delineated in the document,
excluding only PAeff, the shaft motors and shaft
motors chain (while the propulsion services auxiliaries are
partially included below in paragraph 4.1.2 B). Some loads
(i.e. thrusters, cargo pumps, cargo gear, ballast pumps,
maintaining cargo, reefers and cargo hold fans) still are
included in the group for sake of transparency, however
their service factor is zero in order to comply with rows 4
and 5 of paragraph 2.5.6 of the Guidelines, therefore making
it easier to verify that all the loads have been considered
in the document and there are no loads left out of the
measurement.
4.1.1 A - Hull, Deck, Navigation and safety
services
- loads included in the Hull services
typically are: ICCP systems, mooring equipment,
various doors, ballasting systems, Bilge systems,
Stabilizing equipment, etc. Ballasting systems are
indicated with service factor equal to zero to
comply with row 5 of paragraph 2.5.6 of the
Guidelines;
- loads included in the deck services typically are:
deck and balcony washing systems, rescue systems,
cranes, etc.;
- loads included in the navigation services typically
are: navigation systems, navigation's external and
internal communication systems, steering systems,
etc.; and
- loads included in the safety services typically are:
active and passive fire systems, emergency shutdown
systems, public address systems, etc.
4.1.2 B - Propulsion service auxiliaries
This group typically
includes: propulsion secondary cooling systems such as
LT cooling pumps dedicated to shaft motors, LT cooling
pumps dedicated to propulsion converters, propulsion
UPSs, etc. Propulsion service Loads do not include shaft
motors (PTI(i)) and the auxiliaries which are
part of them (shaft motor own cooling fans and pump,
etc.) and the shaft motor chain losses and auxiliaries
which are part of them (i.e. shaft motor converters
including relevant auxiliaries such as converter own
cooling fans and pumps, shaft motor transformers
including relevant auxiliaries losses such as propulsion
transformer own cooling fans and pumps, shaft motor
Harmonic filter including relevant auxiliaries losses,
shaft motor excitation system including the relevant
auxiliaries consumed power, etc.). Propulsion service
auxiliaries include manoeuvring propulsion equipments
such as manoeuvring thrusters and their auxiliaries
whose service factor is to be set to zero.
4.1.3 C – Auxiliary Engine and Main Engine
Services
This group
includes: cooling systems, i.e. pumps and fans for
cooling circuits dedicated to alternators or propulsion
shaft engines (seawater, technical water dedicated
pumps, etc.), lubricating and fuel systems feeding,
transfer, treatment and storage, ventilation system for
combustion air supply, etc.
4.1.4 D – Ship's General services
This group includes Loads which provide
general services which can be shared between shaft
motor, auxiliary engines and main engine and
accommodation support systems. Loads typically included
in this group are: Cooling systems, i.e. pumping
seawater, technical water main circuits, compressed air
systems, fresh water generators, automation systems,
etc.
4.1.5 E - Ventilation for Engine-rooms and
Auxiliaries room
This
group includes all fans providing ventilation for
engine-rooms and auxiliary rooms that typically are:
Engine-rooms cooling supply-exhaust fans, auxiliary
rooms supply and exhaust fans. All the fans serving
accommodation areas or supplying combustion air are not
included in this group. This group does not include
cargo hold fans, and garage supply and exhaust fans.
4.1.6 F - Air Conditioning services
All Loads that make up the
air conditioning service that typically are: air
conditioning chillers, air conditioning cooling and
heating fluids transfer and treatment, air
conditioning's air handling units ventilation, air
conditioning re-heating systems with associated pumping,
etc. The air conditioning chillers service factor of
load, service factor of time and service factor of duty
are to be set as 1 (kl=1, kt=1 and kd=1) in
order to avoid the detailed validation of the heat load
dissipation document (i.e. the chiller's electric motor
rated power is to be used). However, kd is to
represent the use of spare chillers (e.g. four chillers
are installed and one out four is spare then
kd=0 for the spare chiller and kd=1
for the remaining three chillers), but only when the
number of spare chillers is clearly demonstrated via the
heat load dissipation document.
4.1.7 G - Galleys, refrigeration and Laundries
services
All Loads
related to the galleys, pantries refrigeration and
laundry services that typically are: Galleys various
machines, cooking appliances, galleys' cleaning
machines, galleys auxiliaries, refrigerated room systems
including refrigeration compressors with auxiliaries,
air coolers, etc.
4.1.8 H - Accommodation services
All Loads related to the accommodation
services of passengers and crew that typically are: crew
and passengers' transportation systems, i.e. lifts,
escalators, etc., environmental services, i.e. black and
grey water collecting, transfer, treatment, storage,
discharge, waste systems including collecting, transfer,
treatment, storage, etc., accommodation fluids
transfers, i.e. sanitary hot and cold water pumping,
etc., treatment units, pools systems, saunas, gym
equipments, etc.
4.1.9 I - Lighting and socket
services
All Loads related
to the lighting, entertainment and socket services. As
the quantity of lighting circuits and sockets within the
ship may be significantly high, it is not practically
feasible to list all the lighting circuits and points in
the EPT for EEDI. Therefore circuits should be grouped
into subgroups aimed to identify possible improvements
of efficient use of power. The subgroups are:
- Lighting for 1) cabins, 2) corridors, 3) technical
rooms/stairs, 4) public spaces/stairs, 5)
engine-rooms and auxiliaries' room, 6) external
areas, 7) garages and 8) cargo spaces. All have to
be divided by main vertical zone; and
- Power sockets for 1) cabins, 2) corridors, 3)
technical rooms/stairs, 4) public spaces/stairs, 5)
engine-rooms and auxiliaries' room, 6) garages and
7) cargo spaces. All have to be divided by main
vertical zone.
The calculation criteria for complex groups (e.g. cabin
lighting and power sockets) subgroups are to be included
via an explanatory note, indicating the load composition
(e.g. lights of typical cabins, TV, hair dryer, fridge,
etc., typical cabins).
4.1.10 L – Entertainment services
This group includes all Loads related to
the entertainment services that typically are: public
spaces audio and video equipments, theatre stage
equipments, IT systems for offices, video games,
etc.
4.1.11 N – Cargo Loads
This group will contain all cargo loads such
as cargo pumps, cargo gear, maintaining cargo, cargo
reefers loads, cargo hold fans and garage fans for sake
of transparency. However, the service factor of this
group is to be set to zero.
4.1.12 M – Miscellaneous
This group will contain all loads which
have not been associated to the above-mentioned groups
but still are contributing to the overall load
calculation of the normal maximum sea load.
