brought in line with the SO-
LAS definition of a bulk carrier (SOLAS Ch. XII). Sec.10
Carriage of Refrigerated Containers This section is new and has
been introduced to meet market
needs for class notations covering container reefer capacity.
Ships complying with the requirements of this section may be
given the new additional class notation RC-1, RC-2 or
RC-3.Comments to the rules may be sent by e-mail to

of passengers. For do-mestic trade, see Pt.1 Ch.1 Sec.2 B900.102
Ships arranged for transport of more than 12 passengersshall be
built in compliance with the relevant requirements inthis section,
and will be assigned one of the mandatory serviceand type notations
Passenger Ship, Car Ferry A (or B),Train Ferry A (or B) or Car and
Train Ferry A (or B). Seealso Sec.3.
A 200 Definitions201 Length of the ship is the length measured
between per-pendiculars taken at the extremities of the deepest
subdivisionload line.202 Deepest subdivision load line is the
waterline, whichcorresponds to the greatest draught permitted by
the subdivi-sion requirements, which are applicable.203 Bulkhead
deck is the uppermost deck up to which thetransverse watertight
bulkheads are carried.204 Margin line is a line drawn at least 76
mm below the up-per surface of the bulkhead deck at side.205
Machinery space shall be taken as extending from themoulded base
line to the margin line and between the extrememain transverse
watertight bulkheads, bounding the spacescontaining the main and
auxiliary propulsion machinery, boil-ers serving the needs of
propulsion, and all permanent coalbunkers. In the case of unusual
arrangements, the Society willconsider the limits of the machinery
spaces.(SOLAS Reg. II-1/2)
B. Hull Arrangement and StrengthB 100 General101 Sufficient
effective side plating area shall be provided soas to transmit the
shear forces and vertical forces to thestrength deck. If the ship's
sides are arranged with rows of win-dows which will significantly
reduce the shear strength, thestrength deck may be defined as a
lower deck than accordingto the definition given for the main
class. The hull structuralstrength is otherwise to be as required
for the main class as-suming design loads for passenger spaces as
for accommoda-tion deck or weather deck whichever is
applicable.
B 200 Double bottoms in passenger ships201 A double bottom shall
be fitted extending from the fore-peak bulkhead to the afterpeak
bulkhead as far as this is prac-ticable and compatible with the
design and proper working ofthe ship.
1) In ships of 50 m and upwards but less than 61 m in lengtha
double bottom shall be fitted at least from the machineryspace to
the forepeak bulkhead, or as near thereto as prac-ticable.
2) In ships of 61 m and upwards but less than 76 m in lengtha
double bottom shall be fitted at least outside the machin-ery
space, and shall extend to the fore and after peak bulk-
3) In ships of 76 m in length and upwards, a double bottomshall
be fitted amidships, and shall extend to the fore andafter peak
bulkheads, or as near thereto as practicable.
(SOLAS Reg. II-1/12).202 Where a double bottom is required to be
fitted its depthshall be to the satisfaction of the Society and the
inner bottomshall be continued out to the ship's sides in such a
manner as toprotect the bottom to the turn of the bilge. Such
protection willbe deemed satisfactory if the line of intersection
of the outeredge of the margin plate with the bilge plating is not
lower atany part than a horizontal plane passing through the point
of in-tersection with the frame line amidships of a transverse
diago-nal line inclined at 25 degrees to the base line and cutting
it ata point one-half the ship's moulded breadth from the
middleline.(SOLAS Reg. II-1/12).203 Small wells constructed in the
double bottom in connec-tion with drainage arrangements of holds,
etc., shall not extenddownward more than necessary. The depth of
the well shall inno case be more than the depth less 460 mm of the
double bot-tom at the centre line, nor shall the well extend below
the hor-izontal plane referred to in paragraph 2. A well extending
to theouter bottom is, however, permitted at the after end of the
shafttunnel. Other wells (e.g., for lubricating oil under main
en-gines) may be permitted by the Society if satisfied that the
ar-rangements give protection equivalent to that afforded by
adouble bottom complying with this Regulation.(SOLAS Reg.
II-1/12).204 A double bottom need not be fitted in way of
watertightcompartments of moderate size used exclusively for the
car-riage of liquids, provided the safety of the ship, in the event
ofbottom or side damage, is not, in the opinion of the
Society,thereby impaired.(SOLAS Reg. II-1/12).B 300 Peak and
machinery space bulkheads, shaft tun-nels301 A forepeak or
collision bulkhead shall be fitted whichshall be watertight up to
the bulkhead deck. This bulkheadshall be located at a distance from
the forward perpendicular ofnot less than 5 per cent of the length
of the ship and not morethan 3 m plus 5 per cent of the length of
the ship.(SOLAS Reg. II-1/10).
Guidance note:The ship length definition given in SOLAS assumes
the perpen-diculars at the extremities of the deepest subdivision
load line.Preliminary calculations can be based on the complete
waterlinelength at the given summer freeboard.

302 Where any part of the ship below the waterline
extendsforward of the forward perpendicular, e.g. a bulbous bow,
thedistances stipulated in paragraph 1 shall be measured from
apoint either:
at the mid-length of such extension; or at a distance 1.5 per
cent of the length of the ship forward
of the forward perpendicular; or at a distance 3 m forward of
the forward perpendicular;
whichever gives the smallest measurement.DET NORSKE VERITAS

see Pt.0 Ch.1 Sec.3, July 2005303 Where a long forward
superstructure is fitted, the fore-peak or collision bulkhead on
all passenger ships shall be ex-tended weathertight to the next
full deck above the bulkheaddeck. The extension shall be so
arranged as to preclude the pos-sibility of the bow door causing
damage to it in the case ofdamage to, or detachment of, a bow
door.(SOLAS Reg. II-1/10).304 The extension required in paragraph 3
need not be fitteddirectly above the bulkhead below, provided that
all parts ofthe extension are not located forward of the forward
limit spec-ified in paragraph 1 or paragraph 2.(SOLAS Reg.
II-1/10).305 Ramps not meeting the above requirements shall be
dis-regarded as an extension of the collision bulkhead.(SOLAS Reg.
II-1/10).306 An afterpeak bulkhead, and bulkheads dividing the
ma-chinery space, as defined in regulation 2, from the cargo
andpassenger spaces forward and aft, shall also be fitted and
madewatertight up to the bulkhead deck. The afterpeak bulkheadmay,
however, be stepped below the bulkhead deck. The after-peak
bulkhead may, however, be stepped below the bulkheaddeck, provided
the degree of safety of the ship as regards sub-division is not
thereby diminished.(SOLAS Reg. II-1/10).307 In all cases stern
tubes shall be enclosed in watertightspaces of moderate volume. The
stern gland shall be situatedin a watertight shaft tunnel or other
watertight space separatefrom the stern tube compartment and of
such volume that, ifflooded by leakage through the stern gland, the
margin linewill not be submerged.(SOLAS Reg. II-1/10).
C. Machinery and SystemsC 100 General101 For ships with class
notation Passenger Ship the ma-chinery and systems are in general
to be as required for themain class.

are given inSOLAS Reg. II-1/21.2
---e-n-d---of---G-u-i-d-a-n-c-e---n-o-t-e---
102 Electrical distribution systems shall be so arranged
thatfire in any main vertical zone, as defined in Pt.4 Ch.10, will
notinterfere with services essential for safety in any other
suchzone. This requirement will be met if main and emergencyfeeders
passing through any such zone are separated both ver-tically and
horizontally as widely as is practicable.
D. Emergency Source of Electrical Power and Emergency
Installations
D 100 General101 Statutory text that has been adopted in the
rules will bewritten in normal rule text font (not italics) with a
reference tothe corresponding statutory regulation. Adopting
statutory re-quirements by reference alone will not be used.
Statutory re-quirements that are outside the scope of class but
important toconsider in association with the rules shall in some
cases be re-ferred to in Guidance notes.102 A self-contained
emergency source of electrical power
103 The emergency source of electrical power,
associatedtransforming equipment, if any, transitional source of
emer-gency power, emergency switchboard and emergency
lightingswitchboard shall be located above the uppermost
continuousdeck and shall be readily accessible from the open deck.

location of the emergency source of electrical pow-er and
associated transforming equipment, if any, the transi-tional source
of emergency power, the emergency switchboardand the emergency
electric lighting switchboards in relation tothe main source of
electrical power, associated transformingequipment, if any, and the
main switchboard shall be such asto ensure to the satisfaction of
the Administration that a fire orother casualty in spaces
containing the main source of electri-cal power, associated
transforming equipment, if any, and themain switchboard or in any
machinery space of category A willnot interfere with the supply,
control and distribution of emer-gency electrical power. As far as
practicable, the space con-taining the emergency source of
electrical power, associatedtransforming equipment, if any, the
transitional source ofemergency electrical power and the emergency
switchboardshall not be contiguous to the boundaries of machinery
spacesof category A or those spaces containing the main source
ofelectrical power, associated transforming equipment, if any,
orthe main switchboard.105 Provided that suitable measures are
taken for safeguard-ing independent emergency operation under all
circumstances,the emergency generator may be used exceptionally,
and forshort periods, to supply non-emergency circuits.Non
essential domestic supplies should not be directly con-nected to
the emergency switchboard.
D 200 Services to be supplied201 The electrical power available

2) started automatically upon failure of the electrical
supplyfrom the main source of electrical power and shall be
au-tomatically connected to the emergency switchboard;those
services referred to in 400 shall then be transferredautomatically
to the emergency generating set. The auto-matic starting system and
the characteristic of the prime-mover shall be such as to permit
the emergency generatorto carry its full rated load as quickly as
is safe and practi-cable, subject to a maximum of 45 seconds;
unless a sec-ond independent means of starting the

emergency switchboard shall be installed as near asis practicable
to the emergency source of electrical power.702 Where the emergency
source of electrical power is agenerator, the emergency switchboard
shall be located in thesame space unless the operation of the
emergency switchboardwould thereby be impaired.703 No accumulator
battery fitted in accordance with thisRegulation shall be installed
in the same space as the emergen-cy switchboard. An indicator shall
be mounted in a suitableplace on the main switchboard or in the
machinery controlroom to indicate when the batteries constituting
either theemergency source of electrical power or the transitional
sourceof emergency electrical power referred to in item 302.3) or
400are being discharged.704 The emergency switchboard shall be
supplied duringnormal operation from the main switchboard by an
intercon-nector feeder which shall be adequately protected at the
mainswitchboard against overload and short circuit and which
shallbe disconnected automatically at the emergency switchboardupon
failure of the main source of electrical power. Where thesystem is
arranged for feedback operation, the interconnectorfeeder is also

The requirements for fire protection in this section applyto any
ship which carries more than twelve passengers.
E 200 Rule references and definitions201 These requirements are
given in addition to those appli-cable for the main class, as given
in Pt.4 Ch.10.202 For fire technical and space definitions, see
Pt.4 Ch.10.
E 300 Documentation301 The following plans and particulars shall
be submittedfor approval:
General arrangement plan showing main vertical zone ar-rangement
including steps and recesses, stairways anddoors.
Arrangement of means of escape from different compart-ments and
escape calculations.
E 400 Main vertical zones and horizontal zones (SOLAS Reg.
II-2/9.2.2.1)401 In ships carrying more than 36 passengers, the
hull, su-perstructure and deckhouses shall be subdivided into main
ver-tical zones by A-60 class divisions. Steps and recesses shallbe
kept to a minimum but where they are necessary, they shallalso
beA-60 class divisions. Open deck spaces, sanitary orsimilar
spaces, tanks, voids and auxiliary machinery spaceshaving little or
no fire risk on one side or where fuel oil tanksare on both sides
of the division the standard may be reducedto A-0.402 In ships
carrying not more than 36 passengers, the hull,superstructure and
deckhouses in way of accommodation andservice spaces shall be
subdivided into main vertical zones byA class divisions.403 As far
as practicable, the bulkheads forming the bound-aries of the main
vertical zones above the bulkhead deck shallbe in line with
watertight subdivision bulkheads situated im-mediately below the
bulkhead deck. The length and width ofmain vertical zones may be
extended to a maximum of 48 m inDET NORSKE VERITAS

order to accommodatea large public space extending for the whole
length of the mainvertical zone provided that the total area of the
main verticalzone is not greater than 1 600 m2 on any deck. The
length orwidth of a main vertical zone is the maximum distance
be-tween the furthermost points of the bulkheads bounding it.404
Such bulkheads shall extend from deck to deck and tothe shell or
other boundaries.405 Where a main vertical zone is subdivided by
horizontalA class divisions into horizontal zones for the purpose
ofproviding an appropriate barrier between a zone with sprin-klers
and a zone without sprinklers, the divisions shall extendbetween
adjacent main vertical zone bulkheads and to the shellor exterior
boundaries of the ship.406 On ships designed for special purposes,
such as automo-bile or railroad car ferries, where the provision of
main verticalzone bulkheads would defeat the purpose for which the
ship isintended, equivalent means for controlling and limiting a
fireshall be substituted and specifically approved by the
Society.Service spaces and ship stores shall not be located on
ro-rodecks unless protected in accordance with the applicable
re-quirements.407 However, in a ship with special category spaces,
anysuch space shall comply with the applicable requirements tosuch
spaces and where such compliance would be inconsistentwith other
requirements for passenger ships specified in thisPart, the
requirements for special category spaces shall prevail.408 The
basic principle underlying the provisions of this par-agraph is
that the main vertical zoning required by 401 and 402may not be
practicable in vehicle spaces of passenger shipsand, therefore,
equivalent protection shall be obtained in suchspaces on the basis
of a horizontal zone concept and by the pro-vision of an efficient
fixed fire-extinguishing system. Based onthis concept, a horizontal
zone may include special categoryspaces on more than one deck
provided that the total overallclear height for vehicles does not
exceed 10 m.(SOLAS Reg. II-2/20.2.2.1)409 The basic principle
underlying the provisions of para-graph 408 is also applicable to
ro-ro spaces. (SOLAS Reg. II-2/20.2.2.2)E 500 Protection of
stairways and lifts in accommoda-tion area (SOLAS Reg.
II-2/9.2.2.5)501 Stairways shall be within enclosures formed of "A"
classdivisions, with positive means of closure at all openings,
ex-cept that:
.1 a stairway connecting only two decks need not be en-closed,
provided the integrity of the deck is maintained byproper bulkheads
or self-closing doors in one 'tween-deckspace. When a stairway is
closed in one 'tween-deckspace, the stairway enclosure shall be
protected in accord-ance with the requirements for decks; and
.2 stairways may be fitted in the open in a public space,
pro-vided they lie wholly within the public space.
502 Lift trunks shall be so fitted as to prevent the passage
ofsmoke and flame from one tween-deck to another and shall
beprovided with means of closing so as to permit the control
ofdraught and smoke. Machinery for lifts located within
stairwayenclosures shall be arranged in a separate room, surrounded
bysteel boundaries, except that small passages for lift cables
arepermitted. Lifts which open into spaces other than
corridors,public spaces, special category spaces, stairways and
externalareas shall not open into stairways included in the means
of es-
E 600 Means of escape from accommodation spaces, service spaces
and control stations (SOLAS Reg. II-2/13.3.2.1 - 13.3.2.4)601 Below
the bulkhead deck two means of escape, at leastone of which shall
be independent of watertight doors, shall beprovided from each
watertight compartment or similarly re-stricted space or group of
spaces. Exceptionally, the Societymay dispense with one of the
means of escape for crew spacesthat are entered only occasionally,
if the required escape routeis independent of watertight doors.602
Where the Society has granted dispensation under theprovisions of
601, this sole means of escape shall provide safeescape. However,
stairways shall not be less than 800 mm inclear width with
handrails on both sides.603 Above the bulkhead deck there shall be
at least twomeans of escape from each main vertical zone or
similarly re-stricted space or group of spaces at least one of
which shallgive access to a stairway forming a vertical escape.604
Stairway enclosures in accommodation and servicespaces shall have
direct access from the corridors and be of asufficient area to
prevent congestion, having in view thenumber of persons likely to
use them in an emergency. Withinthe perimeter of such stairway
enclosures, only public toilets,lockers of non-combustible material
providing storage for non-hazardous safety equipment and open
information counters arepermitted. Only public spaces, corridors,
lifts, public toilets,special category spaces and open ro-ro spaces
to which anypassengers carried can have access, other escape
stairways re-quired by 605 and external areas are permitted to have
directaccess to these stairway enclosures. Small corridors or
"lob-bies" used to separate an enclosed stairway from galleys
ormain laundries may have direct access to the stairway
providedthey have a minimum deck area of 4.5 m2, a width of no
lessthan 900 mm and contain a fire hose station.605 At least one of
the means of escape required by 601 and603 shall consist of a
readily accessible enclosed stairway,which shall provide continuous
fire shelter from the level of itsorigin to the appropriate
lifeboat and liferaft embarkationdecks, or to the uppermost weather
deck if the embarkationdeck does not extend to the main vertical
zone being consid-ered. In the latter case, direct access to the
embarkation deckby way of external open stairways and passageways
shall beprovided and shall have emergency lighting and slip-free
sur-faces underfoot. Boundaries facing external open stairwaysand
passageways forming part of an escape route and bounda-ries in such
a position that their failure during a fire would im-pede escape to
the embarkation deck shall have fire integrity,including insulation
values, in accordance with appropriate re-quirements.606 Protection
of access from the stairway enclosures to thelifeboat and liferaft
embarkation areas shall be provided eitherdirectly or through
protected internal routes which have fire in-tegrity and insulation
values as required for stairway enclo-sures.
607 Stairways serving only a space and a balcony in thatspace
shall not be considered as forming one of the requiredmeans of
escape.608 Each level within an atrium shall have two means of
es-cape, one of which shall give direct access to an enclosed
ver-tical means of escape meeting the requirements of 605.609 The
widths, number and continuity of escapes shall be inaccordance with
the requirements in the Fire Safety SystemsCode.

widely separated as possible,leading to doors in the upper part of
the space similarlyseparated and from which access is provided to
the appro-priate lifeboat and liferaft embarkation decks. One
ofthese ladders shall be located within a protected enclosurefrom
the lower part of the space it serves to a safe positionoutside the
space. Self-closing fire doors of the same fireintegrity standards
shall be fitted in the enclosure. Theladder shall be fixed in such
a way that heat is not trans-ferred into the enclosure through
non-insulated fixingpoints. The protected enclosure shall have
minimum inter-nal dimensions of at least 800 mm x 800 mm, and
shallhave emergency lighting provisions; or
.2 one steel ladder leading to a door in the upper part of
thespace from which access is provided to the embarkationdeck and
additionally, in the lower part of the space and ina position well
separated from the ladder referred to, asteel door capable of being
operated from each side andwhich provides access to a safe escape
route from the low-er part of the space to the embarkation
deck.
702 Where the space is above the bulkhead deck, the twomeans of
escape shall be as widely separated as possible andthe doors
leading from such means of escape shall be in a po-sition from
which access is provided to the appropriate lifeboatand liferaft
embarkation decks. Where such means of escaperequire the use of
ladders, these shall be of steel.703 In a ship of less than 1 000
gross tonnage, the Societymay dispense with one of the means of
escape, due regard be-ing paid to the width and disposition of the
upper part of thespace. In a ship of 1 000 gross tonnage and above,
the Societymay dispense with one means of escape from any such
space,including a normally unattended auxiliary machinery space,
solong as either a door or a steel ladder provides a safe
escaperoute to the embarkation deck, due regard being paid to the
na-ture and location of the space and whether persons are normal-ly
employed in that space. In the steering gear space, a secondmeans
of escape shall be provided when the emergency steer-ing position
is located in that space unless there is direct accessto the open
deck.704 Two means of escape shall be provided from a machin-ery
control room located within a machinery space, at least oneof which
shall provide continuous fire shelter to a safe positionoutside the
machinery space.
E 800 Means of escape from special category and open ro-ro
spaces to which any passengers carried can have access (SOLAS Reg.
II-2/13.5)801 In special category and open ro-ro spaces to which
anypassengers carried can have access, the number and locationsof
the means of escape both below and above the bulkheaddeck shall be
to the satisfaction of the Society and, in general,the safety of
access to the embarkation deck shall be at leastequivalent to that
provided for under 601, 603, 605 and 606.Such spaces shall be
provided with designated walkways to themeans of escape with a
breadth of at least 600 mm. The park-ing arrangements for the
vehicles shall maintain the walkwaysclear at all times.802 One of
the escape routes from the machinery spaceswhere the crew is
normally employed shall avoid direct accessto any special category
space.
E 900 Additional requirements to means of escape for ro-ro
passenger ships901 Escape routes shall be provided from every
normally oc-cupied space on the ship to an assembly station. These
escaperoutes shall be arranged so as to provide the most direct
routepossible to the assembly station, and shall be marked with
(SOLAS Reg. II-2/13.7.1.1)Guidance note:Refer to Symbols related
to life-saving appliances and arrange-ments adopted by IMO by Res.
A.760(18).

902 The escape route from cabins to stairway enclosuresshall be
as direct as possible, with a minimum number ofchanges in
direction. It shall not be necessary to cross from oneside of the
ship to the other to reach an escape route. It shall notbe
necessary to climb more than two decks up or down in orderto reach
an assembly station or open deck from any passengerspace.(SOLAS
Reg. II-2/13.7.1.2)903 External routes shall be provided from open
decks, as re-ferred to in 902, to the survival craft embarkation
stations.(SOLAS Reg. II-2/13.7.1.3)904 Where enclosed spaces adjoin
an open deck, openingsfrom the enclosed space to the open deck are,
where practica-ble, to be capable of being used as emergency
exits.(SOLAS Reg. II-2/13.7.1.4)905 Escape routes shall not be
obstructed by furniture andother obstructions. With the exception
of tables and chairswhich may be cleared to provide open space,
cabinets and oth-er heavy furnishings in public spaces and along
escape routesshall be secured in place to prevent shifting if the
ship rolls orlists. Floor coverings are also to be secured in
place. When theship is underway, escape routes shall be kept clear
of obstruc-tions such as cleaning carts, bedding, luggage and boxes
ofgoods.(SOLAS Reg. II-2/13.7.1.5)906 Escape routes shall be
evaluated by an evacuation anal-ysis early in the design process.
The analysis shall be used toidentify and eliminate, as far as
practicable, congestion whichmay develop during an abandonment, due
to normal move-ment of passengers and crew along escape routes,
includingthe possibility that crew may need to move along these
routesin a direction opposite the movement of passengers. In
addi-tion, the analysis shall be used to demonstrate that escape
ar-rangements are sufficiently flexible to provide for
thepossibility that certain escape routes, assembly stations,
em-barkation stations or survival craft may not be available as a
re-sult of a casualty.(SOLAS Reg. II-2/13.7.4)
