FIRST SCHEDULE

REGULATIONS ON LOAD LINES

ANNEX I

(regulations 3(2), 4 and 14{c)(iv))

REGULATIONS FOR DETERMINING LOAD LINES

CHAPTER I

GENERAL

The regulations assume that the nature and stowage of the cargo, ballast etc. are such as to secure sufficient stability of the ship and the avoidance of excessive structural stress.

The regulations also assume that where there are international requirements relating to stability or subdivision, these requirements have been complied with.

Regulation 1

Strength and intact stability of ships

( 1)

The Certifying Authority shall satisfy itself that the general structural strength of the ship is adequate for the draught corresponding to the freeboard assigned.

(2)

A ship which is designed, constructed and maintained in compliance with the appropriate requirements of the Certifying Authority, may be considered to provide an acceptable level of strength. The above provisions shall apply to all structures, equipment and fittings covered by this Annex for which standards for strength and construction are not expressly provided.

(3)

Ships shall comply with an intact stability standard acceptable to the Certifying

Authority.

RegulaHon 2

Application

(ll Ships with mechanical means of propulsion or lighters, barges or other ships without independent means of propulsioR shall be assigned freeboards in accordance with the provisions of regulations 1 to 40 of this Annex.

12)

Ships carrying timber deck cargoes may be assigned, in addition to the free boards prescribed in sub-regulation I 1), timber freeboards in accordance with the provisions of regulations 41 to 45 of this Annex.

(3)

Ships designed to carry sail, whether as the sole means of propulsion or as a supplementary means, and tugs, shall be assigned freeboards in accordance with the provisions of regulations 1 to 40 of this Annex. Additional freeboard may be required as determined by the Certifying Authority.

1686

(4)

Ships of wood or of composite construction, or of other materials the use of which the Certifying Authority has approved, or ships whose constructional features are such as to render the application of the provisions of this Annex unreasonable or impracticable, shall be assigned freeboards as determined by the Certifying Authority.

(5)

Regulations 10 to 26 of this Annex shall apply to every ship to which a minimum freeboard is assigned. Variations from the requirements may be granted to a ship to which a greater than minimum freeboard is assigned on condition that the Director is satisfied with the safety conditions provided.

(6)

Where the assigned summer freeboard is increased such that the resulting draught is not more than that corresponding to a minimum summer freeboard for the same ship, but with an assumed freeboard deck located a distance below the actual freeboard deck at least equal to the standard superstructure height, the conditions of assignment in accordance with regulations 12, 14-1 to 20, 23, 24 and 25 of this Annex, as applicable, to the actual freeboard deck may be as required for a superstructure deck.

(7)

Unless expressly provided otherwise, the regulations of this Annex shall apply to ships the keels of which are laid or at a similar stage of construction on or after 1st January 2005.

(8)

For ships the keels of which are laid or which are at a similar stage of construction before 1st January 2005, the Certifying Authority shall ensure that the requirements which are applicable under the Convention are complied with.

(9)

High-speed craft which comply with the requirements of the International

Code of Safety for High-Speed Craft, 2000 and which have been surveyed and certified as provided in the Code shall be deemed to have complied with the requirements of this

Annex. The certificates and permits issued under the Code shall have the same force and the same recognition as the certificates issued under this Annex.

( 10)

In calculating freeboard for ships of less than 24 metres in length, the length of ship shall be taken as 24 metres.

( 11)

Variations or dispensations from the requirements of this Annex may be granted to new ships of less than 24 metres in length and existing ships of less than 150 tons if the Director is satisfied that the ship's constructional features and nature of

·

voyage render the compliance with this Annex impracticable or unreasonable.

Regulation 2-1

Authorisation of Certifying Authority

Certifying Authority shall comply with the guidelines, specifications and amendments adopted and brought into force by the International Maritime Organisation.

Figure 3.2 1688

Perpendiculars

(2)

The forward and after perpendiculars shall be taken at the forward and after ends of the length (L). The forward perpendicular shall coincide with the foreside of the stem on the· water-line on which the length is measured.

Amidships

(3)

Amidships is at the middle of the length (L).

Breadth

(4)

Unless expressly provided otherwise, the breadth (B) is the maximum breadth of the ship, measured amidships to the moulded line of the frame in a ship with a metal shell and to the outer surface of the hull in a ship with a shell of any other material.

Moulded depth

(5)

{a} The moulded depth is the vertical distance measured from the top of the keel to the top of the freeboard deck beam at side. In wood and composite ships the distance is measured from the lower of the keel rabbet. Where the form at the lower part of the midship section is of a hollow character, or where thick garboards are fitted, the distance is measured from the point where the line of the flat of the bottom continued inwards cuts the side of the keel.

{bj

In ships having rounded gunwales, the moulded depth shall be measured to the point of intersection of the moulded lines of deck and sides, the lines extending as though the gunwales were of angular design.

{cj Where the freeboard deck is stepped and the raised part of the deck extends over the point at which the moulded depth is to be determined, the moulded depth shall be measured to a line of reference extending from the lower part of the deck along a line parallel with the raised part.

Depth for freeboard (D)

1689

(6)

{a} The depth for freeboard (D) is the moulded depth amidships, plus the freeboard deck thickness at side.

{bj The depth for freeboard (D) in a ship having a rounded gunwale with a radius greater than 4% of the breadth (B) or having topsides of unusual form is the depth for freeboard of a ship having a midship section with vertical topsides and with the same round of beam and area of topside section equal to that provided by the actual midship section.

Block coefficient

(7)

C =

; where b

L·B·d

I is the volume of the moulded displacement of the ship, excluding appendages, in a ship with a metal shell, and is the volume of displacement to the outer surface of the hull in a ship with a shell of any other material, both taken at a moulded draught of d1; and where is 85% of the least moulded depth.

Freeboard

(8)

The freeboard assigned is the distance measured vertically downwards amidships from the upper edge of the deck line to the upper edge of the related load line.

Freeboard deck

(9)

{b)

Lower deck as a freeboard deck

At the option of the owner and subject to the approval of the ' Certifying

Authority, a lower deck may be designated as the freeboard deck provided it is a complete and permanent deck continuous in a fore and aft direction at least between the machinery space and peak bulkheads and continuous athwartships.

(il

When this lower deek is stepped, the lowest line of the deck and the continuation of that line parallel to the upper part of the deck is taken as the freeboard deck.

(ii)

When a lower deck is designated as the freeboard deck, that part of the hull which extends above the freeboard deck is treated as a superstructure so far as concerns the application of the conditions of assignment and the calculation of freeboard. It is from this deck that the freeboard is calculated.

1690

1691 31st. DECEMBER, 2007

(iii)

When a lower deck is designated as the freeboard deck, such deck as a minimum shall consist of suitably framed stringers at the ship sides and transversely at each watertight bulkhead which extends to the upper deck, within cargo spaces. The width of these stringers shall not be less than can be conveniently fitted having regard to the structure and the operation of the ship. Any arrangement of stringers shall be such that structural requirements can also be met.

{c)

Discontinuous freeboard deck, stepped freeboard deck

(i)

Where a recess in the freeboard deck extends to the sides of the ship and is in excess of one metre jn length, the lowest line of the exposed and the continuation of that line parallel to the upper part of the deck is taken as the freeboard deck (see Figure 3.3).

Iii)

Where a recess in the freeboard deck does not extend to the sides of the ship, the upper part of the deck is taken as the freeboard deck.

(iii)

Recesses not extending from side to side in a deck below the exposed deck, designated as the freeboard deck, may be disregarded, provided all openings in the weather deck are fitted with weathertight closing appliances.

(iv)

Due regard shall be given to the drainage of the exposed recesses and to free surface effects on stability.

(v)

The provisions of sub-paragraphs (i) to (iv) are not intended to apply to dredgers, hopper barges or other similar types of ships with large open holds, where each case requires individual consideration.

(b}

An enclosed superstructure is a superstructure with

(i)

enclosing bulkheads of efficient construction;

(ii)

access openings, if any, in these bulkheads fitted with doors complying with the requirements of regulation 12 of this Annex;

(iii)

all other openings in sides or ends of the superstructure fitted with efficient weathertight means of closing.

A bridge or poop shall not be regarded as enclosed unless access is provided for the crew starting from any point on the uppermost complete exposed deck or higher to reach machinery and other working spaces inside these superstructures by alternative means which are available at all times when bulkhead openings are closed.

(d)

The length of a superstructure (S) is the mean length of the part of the superstructure which lies within the length (L).

(e}

Bridge

A bridge is a superstructure which does not extend to either the forward or after perpendicular.

({)

Poop

A poop is a superstructure which extends from the after perpendicular forward to a point which is aft of the forward perpendicular. The poop may originate from a point aft of the after perpendicular.

(g)

Forecastle

A forecastle is a superstructure which extends from the forward perpendicular aft to a point which is forward of the after perpendicular. The forecastle may originate from a point forward of the forward perpendicular.

(h)

Full superstructure

A full superstructure is a superstructure which, as a minimum, extends from the forward to the after perpendicular.

1692

{i) Raised quarter deck

A raised quarter deck is a superstructure which extends forward from the after perpendicular, generally has a height less than a normal superstructure, and has an intact front bulkhead !sidescuttles of the non-opening type fitted with efficient deadlights and bolted manhole covers) (see Figure 3.4). Where the forward bulkhead is not intact due to doors and access openings, the superstructure is then to be considered as a poop.

where lw and It are defined in sub-regulation 4(a);

[v)

to adjust the freeing port area for the distance of the well deck above the freeboard deck, for decks located more than 0.5h8 above the freeboard deck, multiply by the factor -

where hw is the distance of the well deck above the freeboard deck and h8 is one standard superstructure height.

(c)

To determine Aw-

(i)

the freeing port area for the open well (Awl shall be calculated in accordance with paragraph (b)[i), using lw to calculate a nominal freeing port area (A'), and then adjusted for the actual height of the bulwark (hb) by the application of one of the following area corrections, whichever is applicable -

for bulwarks greater than 1.2 metres in height for bulwarks greater than 0.9 metre in height-for bulwarks between 1.2 metres and 0.9 metre in height there ls no correction [i.e. Ac = 0);

Freeboards at intermediate lengths of ship shall be obtained by linear interpolation.

Ships above 200 metres in length shall be dealt with by the Certifying Authority.

(7)

TYpe 'B' ships, which in position 1 have hatchways fitted with hatch covers complying with the requirements of regulation 16(2) to {5) of this Annex shall, except as provided in sub-regulations (8) to ( 13), be assigned free boards based on Table 28.2.

(8)

Any type 'B' ship of over 100 metres in length may be assigned freeboards less than those required under sub-regulation (7), provided that, in relation to the amount of reduction granted, the Certifying Authority is satisfied that -

(a}

the measures provided for the protection of the crew are adequate;

(c} the covers in positions 1 and 2 comply with regulations 16{1) to (5) and (7)

of this Annex; and

(9)

In calculating the freeboards for type 'B' ships which comply with the requirements of sub-regulations (8L (11), (12) and (13), the values from Table 28.2 shall not be reduced by more than 60% of the difference between the tabular values in Tables 28.1

and 28.2 for the appropriate ship lengths.

1724

(10}

{a} The reduction in tabular freeboard allowed under sub-regulation (9) may be increased up to the total difference between the values in Table 28.1 and those in

Table 28.2 on condition that the ship complies with the requirements of -

(i)

regulation 26 of this Annex, other than sub-regulation (5), as if it were a type '~ ship;

(ii)

sub-regulations (8), ill) and (13); and liii) sub-regulation (12), provided that throughout the length of the ship any one transverse bulkhead will be assumed to be damaged, such that 2 adjacent fore and aft compartments shall be flooded simultaneously, except that such damage will not apply to the boundary bulkheads of a machinery space.

{b)

In such a ship, if over 150 metres in length, the machinery space shall be treated as a floodable compartment, but with a permeability of 0.

85.

Initial condition of loading

( 11)

The initial condition of loading before flooding shall be determined as follows-

1725

{a} the ship is loaded to its Summer Load Line on an imaginary even keel;

{bJ when calculating the vertical centre of gravity, the following principles apply-

(i)

homogeneous cargo is carried;

(ii)

all cargo compartments, except those referred to under sub-paragraph

(iv)

50% of the individual total capacity of all tanks and spaces fitted to contain consumable liquids and stores is allowed for. It shall be assumed that for each type of liquid, at least one transverse pair or a single centreline tank has maximum free surface, and the tank or combination of tanks to be taken into account shall be those where the effect of free surfaces is the greatest; in each tank the centre of gravity of the contents shall be taken at the centre of volume of the tank. The remaining tanks shall be assumed either completely empty or completely filled, and the distribution of consumable liquids between these tanks shall be effected so as to obtain the greatest possible height above the keel for the centre of gravity;

(v)

at an angle of heel of not more than 5° in each compartment containing liquids, as prescribed in sub-paragraph {ii), except that in the case of compartments containing consumable fluids, as prescribed in sub-paragraph {iv), the maximum free surface effect shall be taken into account Alternatively, the actual free surface effects may be used, provided the methods of calculation are acceptable to the

Certifying Authority;

(vi)

weights shall be calculated on the basis of the following values for specific gravities -

salt water 1.025

fresh water 1.000

oil fuel 0.950

diesel oil 0.900

lubricating oil 0.

900.

Damage assumptions

( 12)

The following principles regarding the character of the assumed damage apply

{a) The vertical extent of damage in all cases is assumed to be from the base line upwards without limit.

{b)

The transverse extent of damage is equal to B/5 or 11.5 metres, whichever is the lesser, measured inboard from the side of the ship perpendicularly to the centreline at the level of the Summer Load Line.

{c) If damage of a lesser extent than specified in paragraphs fa) and {b) results in a more severe condition, such lesser extent shall be assumed.

{d)

Except where otherwise required by regulation (10){a) of this Annex, the flooding shall be confined to a single compartment between adjacent transverse bulkheads, provided that the inner longitudinal boundary of the compartment is not in a position within the transverse extent of assumed damage. Transverse boundary bulkheads of wing tanks which do not extend over the full breadth of the ship shall be assumed not to be damaged, p;ovided they extend beyond the transverse extent of assumed damage prescribed in paragraph {b).

If in a transverse bulkhead there are steps or recesses of not more than 3 metres in length located within the transverse extent of assumed damage as defined in paragraph {b} such transverse bulkhead may be considered intact and the adjacent compartment may be floodable singly. If, however, within the transverse extent of assumed damage there is a step or recess of more than 3 metres in length in a transverse bulkhead, the 2 compartments adjacent to this bulkhead shall be 1726

considered as flooded. The step formed by the afterpeak bulkhead and the afterpeak tank top shall not be regarded as a step for the purpose of this regulation.

{e}

Where a main transverse bulkhead is located within the transverse extent of assumed damage and is stepped in way of a double bottom or side tank by more than 3 metres, the double bottom or side tanks adjacent to the stepped portion of the main transverse bulkhead shall be considered as flooded simultaneously. If this side tank has openings into one or several holds, such as grain feeding holes, such hold or holds shall be considered as flooded simultaneously. Similarly in a ship designed for the carriage of fluid cargoes, if a side tank has openings into adjacent compartments, such adjacent compartments shall be considered as empty and as being flooded simultaneously. This provision is applicable even where such openings are fitted with closing appliances, except in the case of sluice valves fitted in bulkheads between tanks and where the valves are controlled from the deck. Manhole covers with closely spaced bolts are considered equivalent to the unpierced bulkhead, except in the case of openings in topside tanks making the topside tanks common to the holds.

ff}

Where the flooding of any 2 adjacent fore and aft compartments is envisaged, main transverse watertight bulkheads shall be spaced at least 113 L213 or 14.5 metres, whichever is the lesser, in order to be considered effective. Where transverse bulkheads are spaced at a lesser distance, one or more of these bulkheads shall be assumed as non-existent in order to achieve the minimum spacing between bulkheads.

Condition of equilibrium

(13)

The condition of equilibrium after flooding shall be regarded as satisfactory provided-

1727

{a} The final water-line after flooding, taking into account sinkage, heel and trim, is below the lower edge of any opening through which progressive downflooding may take place. Such openings shall include air pipes, ventilators

(even if they comply with regulation 19(4) of this Annex) and openings which are closed by means of weathertight doors (even if they comply with regulation 12 of this Annex) or hatch covers (even if they comply with regulation 16(1) to (5) of this

Annex), and may exclude those openings closed by means of manhole covers and flush scuttles (which comply with regulation 18 of this Annex), cargo hatch covers of the type described in regulation 27(2) of this Annex, remotely operated sliding watertight doors, and sidescuttles of the non-opening type (which comply with regulation 23 of this Annex). However, in the case of doors separating a main machinery space from a steering gear compartment, watertight doors may be of a hinged, quick-acting type kept closed at sea whilst not in use, provided also that the lower sill of such doors is above the Summer Load Line.

{b) If pipes, ducts or tunnels are situated within the assumed extent of damage penetration as defined in sub-regulation (12){b}, arrangements shall be made so that progressive flooding cannot thereby extend to compartments other than those assumed to be floodable in the calculation for each case of damage.

{cj The angle of heel due to unsymmetrical flooding does not exceed 15°. If no part of the deck is immersed, an angle of heel of up to 17° may be accepted.

BRUNEI DARUSSALAM GOVERNMENT GAZETTE fd} The metacentric height in the flooded condition is positive.

fe} When any part of the deck outside the compartment assumed flooded in a particular case of damage is immersed, or in any case where the margin of stability in the flooded condition may be considered doubtful, the residual stability is to be investigated. It may be regarded as sufficient if the righting lever curve has a minimum range of 20° beyond the position of equilibrium with a maximum righting lever of at least 0.1 metre within this range. The area under the righting lever curve within this range shall be not less than 0.0175 metre radius. The Certifying

Authority shall give consideration to the potential hazard presented by protected or unprotected openings which may become temporarily immersed within the range of residual stability.

if} The Certifying Authority is satisfied that the stability is sufficient during intermediate stages of flooding.

Ships without means of propulsion

(14)

A lighter, barge or other ship without independent means of propulsion shall be assigned a freeboard in accordance with the provisions of these regulations. Barges which meet the requirements of sub-regulations (2) and j3) may be assigned type 'A!.

freeboards-fa} The Certifying Authority should especially consider the stability of barges with cargo on the weather deck. Deck cargo can only be carried on barges to which the ordinary type 'B' freeboard is assigned.

fb}

However, in the case of barges which are unmanned, the requirements of regulations 25, 26(3) and (4) and regulation 39 of this Annex shall not apply.

fc} Such unmanned barges which have on the freeboard deck only small access openings closed by watertight gasketed covers of steel or equivalent material may be assigned a freeboard 25% less than those calculated in accordance with these regulations.

Regulation 29

Correction to the freeboard for ships under 100 metres in length

The tabular freeboard for a type 'B' ship of between 24 metres and 100 metres in length having enclosed superstructures with an effective length of up to 35% of the length of the ship shall be increased by -

7.5(100 - L { 0.35 - ~·) ~illimetres where L is the length of ship in metres,

E1

is the effective length E of superstructure in metres as defined in regulation 35 of this Annex but excluding the length of trunks.

Regulation 30

Correction for block coefficient

Where the block coefficient (Cb) exceeds 0.68, the tabular freeboard specified in regulation 28 of this Annex as modified, if applicable, by regulations 27(8), 27(10) and 29 of this Annex shall be multiplied by the factor -

Regulation 31

Correction for depth

( 1)

Where D exceeds 1~

the free board shall be increased by ( D -

(2)

Where D is less than 1~ no reduction shall be made except in a ship with an enclosed superstructure covering at least 0.6L amidships, with a complete trunk, or combination of detached enclosed superstructures and trunks which extend all fore and aft, where the freeboard shall be reduced at the rate prescribed in sub-regulation (1).

(3)

Where the height of the superstructure or trunk is less than the standard height, the calculated reduction shall be corrected in the ratio of the height of the actual superstructure or trunk to the applicable standard height as defined in regulation 33 of this

Annex.

1737

Regulation 32

Correction for position of deck line

Where the actual depth to the upper edge of the deck line is greater or less than D, the difference between the depths shall be added to or deducted from the freeboard.

Regulation 32-1

Correction for recess in freeboard deck 11)

Where a recess is arranged in the freeboard deck, and it does not extend to the sides of the ship, the freeboard calculated without regard to the recess shall be corrected for the consequent loss of buoyancy. The correction shall be equal to the value obtained by dividing the volume of the recess by the waterplane area of the ship at 85% of the least moulded depth {see Figure 32-1.1).

(21

The correction shall be an addition to the freeboard obtained after all other corrections have been applied, except bow height correction.

{3)

Where the freeboard, corrected for lost buoyancy as above, is greater than the minimum geometric freeboard determined on the basis of a moulded depth measured to the bottom of the recess, the latter value may be used.

Standard height (metres)

Raised quarter deck 0.90 1.20

All other superstructures 1.80 1.80

The standard heights at intermediate lengths of the ship shall be obtained by linear interpolation.

Regulation 34

Length of superstructure

Ill Except as provided in sub-regulation (2). the length of a superstructure IS) shall be the mean length of the parts of the superstructure which lie within the length (L).

Where a superstructure bulkhead is recessed, the effective length of the superstructure shall be reduced by an amount equal to the area of the recess in plan view divided by the breadth of the superstructure at the midlength of the recess.

Where the recess is unsymmetrical about the centerline, the largest portion of the recess shall be considered as applying to both sides of the ship. A recess need not be decked over.

(2)

Where the end bulkhead of an enclosed superstructure extends in a fair convex curve beyond its intersection with the superstructure sides, the length of the superstructure may be increased on the basis of an equivalent plane bulkhead. This increase shall be two-thirds of the fore and aft extent of the curvature. The maximum curvature which may be taken into account in determining this increase is one-half the breadth of the superstructure at the point of intersection of the curved end of the superstructure with its side.

Where there is an extension to a superstructure, which extension has a breadth on each side of the centerline at least 30% of the breadth of the ship, the effective length of the superstructure may be increased by considering an equivalent superstructure bulkhead in the form of a parabola. This parabola shall extend from the extension at the centerline and pass through the junction of the actual superstructure bulkhead with the sides of the extension and extend to the sides of the ship. This parabola shall be completely contained within the boundary of the superstructure and its extensions.

1739

If the superstructure is set in from the side, up to the limit allowed under regulation 3(10) of this Annex, the equivalent bulkhead should be calculated on the basis of the actual breadth of the superstructure (and not the breadth of the ship).

(3)

Superstructures which have sloped end bulkheads shall be dealt with in the following manner

(a} When the height of superstructure, clear of the slope, is equal to or smaller than the standard height, the length S is to be obtained as shown in Figure 34.1.

(b}

When the height is greater than the standard, the lengthS is to be obtained as shown in Figure 34.2.

(cj The foregoing will apply only when the slope, related to the baseline, is 15°

or greater. Where the slope is less than 15° 1 the configuration shall be treated as sheer.

Regulation 35

Effective length of superstructure

(1)

Except as provided for in sub-regulation (2), the effective length (E) of an enclosed superstructure of standard height shall be its length.

(2)

In all cases where an enclosed superstructure of standard height is set in from the sides of the ship as permitted in regulation 3( 10) of this Annex, the effective length shall be the length modified by the ratio of b/B5, where-b is the breadth of the superstructure at the middle of its length; and

B5

is the breadth of the ship at the middle of the length of the superstructure.

Where a superstructure is set in for a part of its length, modification shall be applied only to the set-in part.

(3)

Where the height of an enclosed superstructure is less than the standard height, the effective length shall be its length reduced in the ratio of the actual height to the standard height. Where the height exceeds the standard, no increase shall be made to the effective length of the superstructure (see Figures 34.1 and 34.2).

Where the height, clear of the slope, of a superstructure which has slope end bulkheads is less than the standard height, its effective length E shall be its length S as obtained from Figure 34.1, reduced in the ratio of the actual height to the standard height.

Where a poop or forecastle of less than standard height is fitted on a ship with excessive sheer but without any superstructure within 0.2L amidships, credit may be given to the height of the poop or forecastle by increasing the actual height by the difference between the actual and the standard sheer profiles. The deduction for excess sheer in accordance with regulation 38(16) of this Annex is not to be granted.

(4)

The effective length of a raised quarter deck, if fitted with an intact front bulkhead, shall be its length up to a maximum of 0.6L. Where the bulkhead is not intact, the raised quarter deck shall be treated as a poop of less than standard height.

The maximum effective length of 0.6L of a raised quarter deck is to be measured from the after perpendicular, even where a poop is fitted in conjunction with the raised quarter deck.

(5)

Superstructures which are not enclosed shall have no effective length.

1741

Regulation 36

Trunks

(1)

A trunk or similar structure which does not extend to the sides of the ship shall be regarded as efficient on the following conditions -

{a)

the trunk is at least as strong as a superstructure;

{b)

the hatchways are in the trunk deck, and the hatchway coamings and covers comply with the requirements of regulations 13 to 16 of this Annex and the width of the trunk deck stringer provides a satisfactory gangway and sufficient lateral stiffness. However, small access openings with watertight covers may be permitted in the freeboard deck;

{c)

a permanent working platform fore and aft fitted with guard rails is provided by the trunk deck, or by detached trunks connected to superstructures by efficient permanent gangways;

(d)

Sheer

General

(1)

The sheer shall be measured from the deck at side to a line of reference drawn parallel to the keel through the sheer line amidships.

(2)

In ships designed with a rake of keel, the sheer shall be measured in relation to a reference line drawn parallel to the design load water-line.

(3)

In flush deck ships and in ships with detached superstructures the sheer shall be measured at the freeboard deck.

(4)

In ships with topsides of unusual form in which there is a step or break in the topsides, the sheer shall be considered in relation to the equivalent depth amidships.

(5)

In ships with a superstructure of standard height which extends over the whole length of the freeboard deck, the sheer shall be measured at the superstructure deck.

Where the height exceeds the standard, the least difference (Z) between the actual and standard heights shall be added to each end ordinate. Similarly, the intermediate ordinates at distances of and .l L from each perpendicular shall be increased by 0.4442 and 3

(9l

Where the sheer profile differs from the standard, the 4 ordinates of each profile in the forward or after half shall be multiplied by the appropriate factors given in the table of ordinates. The difference between the sums of the respective products and those of the standard divided by 8 measures the deficiency or excess of sheer in the forward or after half. The arithmetical mean of the excess or deficiency in the forward and after halves measures the excess or deficiency of sheer.

( 10)

Where the after half of the sheer profile is greater than the standard and the forward half is less than the standard, nu credit shall be allowed for the part in excess and deficiency only shall be measured.

( 11 J Where the forward half of the sheer profile exceeds the standard, and the after portion of the sheer profile is not less than 75% of the standard, credit shall be allowed for the part in excess. Where the after part is less than 50% of the standard, no credit shall be given for the excess sheer forward. Where the after sheer is between 50% and 75% of the standard, intermediate allowances may be granted for excess sheer forward.

L'

is the mean enclosed length of poop or forecastle up to a maximum length of 0.5L;

L is the length of the ship as defined in regulation 3(1) of this Annex.

The above formula provides a curve in the form of a parabola tangent to the actual sheer curve at the freeboard deck and intersecting the end ordinate at a point below the superstructure deck a distance equal to the standard height of a superstructure. The superstructure deck shall not be less than standard height above this curve at any point.

This curve shall be used in determining the sheer profile for forward and after halves of the ship.

1747

(13)

(a} Any excess in the height of a superstructure which does not extend to the after perpendicular cannot be regarded as contributing to the sheer allowance.

(b} Where the height of a superstructure is less than standard, the superstructure deck shall not be less than the minimum height of the superstructure above the virtual sheer curve at any point. For this purpose y shall be taken as the difference between the actual and minimum height of the superstructure at the after/

forward perpendicular.

(c)

For a raised quarter deck credit may be given only when the height of this quarter deck is greater than the standard height of 'other superstructures' as defined in regulation 33 of this Annex, and only for the amount by which the actual height of the raised quarter deck exceeds that standard height.

(d)

When a poop or forecastle has sloping end bulkheads, the sheer credit may be allowed on account of excess height. The formula given in sub-regulation 112) shall be used, the values for y and L' being as shown in Figure 38.

Maritime Organisation, as amended}.

Timber load line

(2)

A timber deck cargo may be regarded as giving a ship a certain additional buoyancy and a greater degree of protection against the sea. For that reason, ships carrying a timber deck cargo may be granted a reduction of freeboard calculated according to the provisions of regulation 45 of this Annex and marked on the ship's side in accordance with the provisions of regulations 6(3) and (4) of this Annex. However, in order that such special freeboard may be granted and used, the timber deck cargo shall comply with certain conditions which are laid down in regulation 44 of this Annex, and the ship itself shall also comply with certain conditions relating to its construction which are set out in regulation 43 of this Annex.
