5. FINAL GENERAL ARRANGEMENT

5.1. Frame Spacing and Bulkhead Disposition 5.1.1 Introduction

The general Arrangement of a ship can be defined as the assignment of spaces for all the required functions and equipments, properly coordinated for location and access.

The requirements that must be met are, a) Volume requirements b) Adequate trim and stability c) Structural integrity d) Watertight subdivision and integrity e) Adequate access to spaces.

The volume below deck is subdivided into: a) Machinery space b) Cargo spaces c) Ballast spaces d) Pump room e) Slop Tank

5.1.2 Basic Hull Framing

The bottom shell, inner bottom, deck, side shell, inner hull bulkheads and longitudinal bulkheads are longitudinally framed. Transverse framing is adopted in fore peak region, aft peak region and machinery space region.

The different regions along with their rule spacing [LRS, Part 3, and Chapter 5, 6] are given below, a) Aft Ice breaking region: 500 mm (taken from trends in Russian Ice class 1A ships)

b) Aft of 0.05 L from AP

s = (470 + L / 0.6) = 908 mm (where L = 263 m) or 600 mm, whichever is the lesser. Taken s = 600 mm


87

c) Between 0.05 L and 0.15 L from AP

s = (510 + L / 0.6) = 948 mm (where L = 263 m) or 850 mm, whichever is the lesser. Taken s = 850 mm

d) Forward of 0.05 L from FP s = (470 + L / 0.6) = 908 mm (where L = 263 m) or 600 mm, whichever is the lesser. Taken s = 600 mm e) Between 0.05 L & 0.2 L from FP s = (470 + L / 0.6) = 908 mm (where L = 263 m) or 700 mm, whichever is the lesser. Taken s = 700 mm

f) Rest of spaces, s = 850mm is adopted.

The maximum frame spacing as permitted by the rules has been calculated. The final frame spacing along the length in accordance with the rules is shown in the table.

5.1.3 Number and Disposition of Bulkheads

The disposition of transverse bulkheads is to comply with the requirements of LRS [LRS, Part3, Chapter 3&4], as applicable to ships with machinery located aft. Minimum number of bulkheads = 9 Number of bulkheads taken = 9 5.1.4 Forward Collision Bulkhead

For ships with bulbous bow [LRS, Part 3, Chapter 3, Section 4] and LL ≥ 200, the distance of collision bulkhead aft of fore end of LL in m is. 10 – f2 (minimum) 0.08 LL– f2 (maximum) Where:

LL = load line length, is to be taken as 96% of total length on WL at 85% of least moulded depth, or as the length from foreside of the stem to the AP on that WL, if that is greater f2 = G/2 or 0.015 LL m, whichever is the lesser G = projection of bulbous bow forward of fore end of LL in m = 4.56 m Here, LL = 270.65 m. G = 4.56 m. Whence f2 = 2.28 m. Minimum distance = 10 – f2 = 7.72 m. Maximum distance = 0.08 LL – f2 = 19.37 m.

Let’s take distance of fore peak bulkhead at a distance of 11.4 m from FP. 5.1.5 Aft Peak Bulkhead

All ships should have one aft peak bulkhead generally enclosing the stern tube and the rudderpost. As provided in the parent ship, aft peak bulkhead is provided at a distance of 12.6 m from AP.


90

5.1.6.1 Length of Engine Room

The length of engine room is determined by the power of the engine, type and whether it is a slow-speed, medium-speed or high-speed engine. Main engine particulars: Type: 9TM620 Number: 3 Manufacturer: STORK WARTSILA DIESEL CO. Holland Rated output: 12,750KW Rated speed: 428rpm

Considering the frame spacing and the information from built ships the length of engine room is fixed as 31.55 m. Length of pump room is 4.25m.

5.1.6.2 Cofferdams

Cofferdams are to be provided at the forward and aft ends of the oil cargo space. These cofferdams should be at least 760 mm in length and should cover the whole area of the bulkheads of the cargo space. Pump room has been incorporated as the aft cofferdam. The fore peak tank forms the forward cofferdam.

5.1.6.3 Slop Tank

According to LRS rule, slop tank should be provided with a minimum capacity of 3% of cargo carrying capacity.

3% of cargo carrying capacity = 3% of 150000 = 4500 t

Assuming a stowage factor of 1.2, 5400 m3 capacity is required for the slop tank, hence length of slop tank taken is 5.1m 5.1.7 Length of Cargo Tanks The structural configuration adopted has been one with a centreline longitudinal bulkhead. For such a configuration the length of the tank [Part 4, Chapter 9] should not exceed, 10 m or (0.25 bi/B + 0.15) LL m, whichever is the greater.

Where bi = minimum distance from side shell to inner hull of tank measured inboard at right angles to the center line at load water line.


91

Here bi = 3.0 m

LL = load line length, is to be taken as 96% of total length on WL at 85% of least moulded depth, or as the length from foreside of the stem to AP on that WL, if that is greater Therefore, LL = 270.65 m (0.25 bi / B + 0.15) LL= 44.76 m

According to the above mentioned restrictions the cargo region is divided into five. For length of cargo tanks see table 5.2.

FIRE PUMP CAPACITY CALCULATIONS

Capacity of fire pump

Q = Cd2 where

C = 5 for ships required to be provided with more than one fire pump (excluding any

emergency fire pump) and C= 2.5 for ships required to be provided with only one fire

pump, and

d = 1+ 0.066 [√ L (B+D)] ⇒ 1+0.066√ 263.07 ( 48.7 +23.76 )] = 10.11

L = length of the ship in meters on the summer load water line from the foreside of the

Stem to the afterside of the rudderpost. Where there is no rudderpost, the length is

measured from the foreside of the stem to the axis of the rudderstock if that be the

greater.

B = greatest moulded breadth of the ship in meters and

D = moulded depth of the ship in meters measured to the bulkhead deck amidships

Q = Cd2

= 5 x 10.112 =511.06 m3/hr

Minimum is 40 m3/hr

Provided is 300 m3/hr@4 bar running at 200 m3/[email protected]

JET THROW CALCULATION

MS (Fire appliances) Rules 1990

Capacity of fire pump = 200 m3/hr

Dia. of nozzle = 19 mm

Cross-sectional area of nozzle = 2.8 x 10-4 m2

Length of the jet throw required = 12 m Jet velocity = 198.4 m/s

Percentage loss due to nozzling and air resistance = 30%

Net jet velocity = 138.8 m/s

Projectile Angle = 45˚

Velocity require at nozzle for 12 m throw

Using formula R = u2 Sin 2θ / g

Where

u = Velocity at the nozzle

θ = Projectile angle to get maximum range = 45˚

a = g (acceleration due to gravity = 9.8 m/s2)

R = Horizontal distance reached by the throw = 12 m.

i.e., u = √ R g / Sin 2θ = 10.84 m/s

Velocity of throw required = 138.4 m/s

Available jet Velocity = 138.4 m/s
