Internal combustion engine and its types An internal combustion engine is one in which the fuel is burnt within the engine. Most of the cases it is of reciprocating type. Combustion of the fuel and the conversion of the heat energy from combustion to mechanical energy takes place within the cylinders. Internal combustion engines can …

Write short notes on following Thrust Block, Intermediate Shaft, Incinerator, Bow Thruster Thrust Block The main thrust block transfers forward or astern propeller thrust to the hull and limits axial movement of the shaft. Some axial clearance is essential to allow formation of an oil film in the wedge shape between the collar and the …

Reverse Osmosis Write short note on “Reverse Osmosis”. Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by water pressure pushing the water through a semipermeable membrane. The RO process works depending on the salt content levels in the water. …
Radial vs Axial displacement pumps. List out the differences between Radial and Axial displacement pumps. Radial Displacement Pump Axial Displacement Pump Cylinder block rotates→ hollow pistons with spring return to move in and out. Piston move axially in a rotating cylinder block→ move by contact with the swash plate. Fluid drawn from inlet port. Shaft …

Rotary vane steering gear system Draw a Rotary vane steering gear system and explain its operation. Rotary vane steering consists of a rotor which is taper fit on the rudder stockand keyed to it and a stator of larger diameter than outside diameter of rotor to form an annular space between them. The stator being …

ALCAP system What is ALCAP system? ALCAP system can purify high density residual fuel. Its flow control disc eliminates the need of gravity disc. As it does not have gravity disc the changing of gravity disc with different density of fuel is not required. It detects water in oil side by a transducer (WMS-water monitoring …
Oily Water Separator Draw and explain OWS operation. #Oily Water Separator The separation of oil water in the separator takes place in two stages. In the first stage the separation is by gravity, whereas in the second stage the separation is by coalescing filters. The bilge pump delivers clean sea water to the first stage …
Plate type cooler Draw a simple plate type cooler and explain. Plate coolers are made up of assembly of identical plates pressed together. The plates have horizontal or Chevron corrugations. The corrugations provide stiffness to the plate thus permitting the use of thinner material in the making. Moreover, it also increases the surface area and …

Centrifugal vs reciprocating pump List out the differences between Centrifugal vs reciprocating pump. Centrifugal pump Reciprocating pump It is one of the rotary pumps which used kinetic energy of impeller. It is a positive displacement type pump which is forced by piston. It continuously discharges the fluid. It does not discharge the fluid continuously. In …
