This document summarizes a design project for a 100 TEU container ship. It includes calculations for stability and trim, resistance and power, engine selection, rudder design, propeller and shaft design, and scantling. Principal particulars of the ship include a length of 74m, breadth of 13m, draught of 3m, and capacity of 100 twenty-foot equivalent units. Calculations show the ship will have a speed of 11 knots powered by a 900kW engine.
The ship at sea or lying in still water is constantly being subjected to a wide variety of stresses and strains, which result from the action of forces from outside and within the ship.

It mainly explains about generation of electricity using floating hydro turbine using spring suspension system .The main important factor is the turbine generates electricity when the wave enter and leave the coast.In this the design is also explained about each and every part in the following PPT
InternalInternal combustion engines provide outstanding drivability and durability, with more than 250 million highway transportation vehicles in the United States relying on them. Along with gasoline or diesel, they can also utilize renewable or alternative fuels (e.g., natural gas, propane, biodiesel, or ethanol). They can also be combined with hybrid electric powertrains to increase fuel economy or plug-in hybrid electric systems to extend the range of hybrid electric vehicles.
HOW DOES AN INTERNAL COMBUSTION ENGINE WORK?
Combustion, also known as burning, is the basic chemical process of releasing energy from a fuel and air mixture. In an internal combustion engine (ICE), the ignition and combustion of the fuel occurs within the engine itself. The engine then partially converts the energy from the combustion to work. The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. Ultimately, through a system of gears in the powertrain, this motion drives the vehicle’s wheels.

70. Trim calculation LCB at LWL =1.162 m fowd. of amidships LCG of total ship = 1.4132m fwd of amidships Load Displacement of the ship = 2240.025 tones At LWL,MCT1m = 3672.3tones. C.F. = 0.621m fwd amidships & Draft = 3 m. Now, Amount of trim= [1.162-(-1.4132)]X 2240.025 / 3672.3 m. = 1.570 m. So, change in trim forward = ( 1.570 – 0.798) m = 0.772 m. Change in trim aft = (l / L)*Change of trim = {(37+.621) / 74 }*1.570 m. =0.798 m.

100. Propeller design CALCULATION OF PROPELLER DIAMETER AND PITCH USING BP – δ The maximum permissible diameter of the propeller would be , DP (max) = 0.7 x draft of ship = 0.7 x 3 , [draft = 3 m ] = 2.1 m We need the following data for the calculation of propeller diameter – Brake power of Engine, PB =884 kW Speed of the vessel, VS = 11 knots Shaft rpm, N = 1800/5.00 = 450 Propeller Type: Fixed Pitch Propeller (FPP) No of blades of propeller, Z = 4 Expanded blade area ratio, AE / AO = 0.55 Now, Delivered power, PD = PB (1 – 0.03) kW [3% shaft loss] = 884 X (1 – 0.03) kW = 857 kW
101. Velocity of advance, VA = VS (1 - wt) [wt = Tailor wake fraction = 0.195] = 8.855 knots Now, BP = {N X √ (1.34 X PD)} / VA 2.5 = 62.75 From BP – δ diagram, when, BP = 34.177, δo = 233 We get, PO / DO = 0.58 Now, δo= 3.28 X N X DO / VA = 300 So,DO = 1.82 m This is less than maximum permissible 2.1 m & PO = 1.82 X 0.58 = 1.0556 m Where, ar = distance between leading edge and generator line at r br = distance between leading edge and location of maximum thickness cr = chord length of blade section at radius r sr = maximum blade section thickness at radius r
102. CALCULATION OF PITCH AT DIFFERENT SECTION: Here, PB / DB = 0.7368 Where, DB = 1.178 m So, PB at 0.6 R, 0.8 R & 1.0 R = 0.868 m At 0.2 R, PB = (82.2% of PB at 1.0 R) = 0.713 m At 0.4 R, PB = (95 % of PB at 1.0 R) = 0.8246 m CALCULATION OF PITCH ANGLE AT DIFFERENT SECTION: We know, tanφ =P / 2πr Where, φ = pitch angle P= pitch at different section Now, using the above formula pitch angle at different section is given below Now using the pitch angle and other data; side elevation, pitch diagram & transverse view is drawn.
