6.  Wear protective equipment.
 Always be alert and awake.
 Follow correct procedures, don’t take shortcuts.
 Clean and organize your workplace.
 Ensure a clear and easy route to emergency exits and equipment.
 All metallic covers over electrical machinery or control equipment should be properly
earthed.
 Underground cables/wires should be safe from mechanical damage or exposure to excessive
moisture.

7.  An aircraft carrier is a warship that serves as a seagoing airbase , equipped with a full length
flight deck and facilities for carrying ,arming, deploying and recovering aircraft.
 Typically it is the capital ship of fleet , as it allows a naval force to project air power world wide
without depending on local bases for staging aircraft operations.

9.  LATHE
 RADIAL DRILLING MACHINE
 SHAPER
 GRINDING MACHINE
 BAND SAW MACHINE

10. Fig. Lathe Machine
 A lathe is a machine tool which is used to rotate a work piece to perform various operations such as
turning, facing, knurling, grooving etc.
 It removes the undesired material from a rotating workpiece in the form of chips with the help of a
tool that is traversed across the work and can be feed deep into the work.

11. Fig. Radial Drilling Machine
 A drilling machine is primarily utilized for drilling holes of different sizes and precise depths on the
surface of an object.
 A drilling machine can even perform several other functions such as tapping, reaming, counter
sinking, spot facing, counter boring, etc.
 It is commonly referred as a drill press; and has the capacity to drill very tiny holes and also extremely
large holes.

12. Fig. Slotting Machine
 Slotting is a reciprocating type of machine tool in which the ram that holds the tool moves in the
vertical axis.
 In the slotting machine the ram reciprocates in the vertical direction.
 The cutting action in the slotting takes place during the downward stroke of the ram, and there is no
cutting in the return stroke and called an idle stroke.

13. Fig. Grinding Machine
 Grinder, is one of power tools or machine tools used for grinding, it is a type of machining using
an abrasive wheel as the cutting tool.
 Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.
 Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness)
and high accuracy of shape and dimension.

14. Fig. Band Saw Machine
 A bandsaw is a power saw with a long, sharp blade consisting of a continuous band of toothed
metal stretched between two or more wheels to cut material.
 They are used principally in woodworking, metalworking, and lumbering, but may cut a variety
of materials.

15. These are used to measure various aspect such as clearance, diameter, depth, flatness etc.
This following are the various instruments used :-
1. VERNIER CALIPER
2. SCREW GAUGE
3. FEELER GAUGE
4. DIAL GAUGE

16. Different Types Of Pumps We Observed In The Industry Are:-
1. GEAR PUMP
2. SCREW PUMP
3. CENTRIFUGAL PUMP

17. Gear Pump:
 A gear pump is a type of positive displacement (PD) pump. Gear pumps use the actions of rotating
cogs or gears to transfer fluids.

18. Screw Pump:
 A screw pump is a subset of positive displacement pump that use one or more than one screw; to
perform pump action along its spindle axis.
Centrifugal Pump:
 Centrifugal pumps are one of the most commonly used pumps on the earth with ever growing
applications. They are simple and reliable machine of any machinery space.

19. Shifting is a process of moving parts from one location to another location.
This following are the various equipment's used in Shifting :
1.Chain Pulley Block
Chain blocks are used extensively to move heavy loads through chain pulling.
Most chain blocks are operated by hand, lever blocks are operated by pulling
a manual lever
2. Rope
Rope is a thick cord or wire that is made by twisting together several thinner
cords or wires.Ropes are used for pulling and tying.

20. 3.Trolley
It is a equipment on wheels that is used for carrying things from one place to another place.

21. Problem Identification
 Leaks
 Corrosion
 Unusual noise
 Vibration
Servicing
 Disconnect power supply wires and motor.
 Disassemble the pump casing
 Clean all the physical parts of pump.
 Inspecting impeller blades, casing for signs of erosion and wear.
 Check all bearings for wear and change if required.
 Using feeler gauge check for clearances.
 Check for uneven movement of the shaft.
 Assembly.

22. Gaskets & glands used in valves:
 A Gasket is an elastomeric component that covers the intersection between two surfaces. They
are usually manufactured from a variety of materials, including rubber, cork or paper, metal,
copper, and foam.
Hydrostatic Test Pump:
 Hydro test pumps are common procedure used to check fluid pressure vessel, such as, cylinders,
boiler, tubes pipe, valves, castings, components etc.

23. Technical Outcomes:
 Understanding working various Machine.
 Understanding the different component of Ship and learning the advantages and disadvantages of
each.
 Learning the basics maintenance process.
 Application of academic knowledge in industrial works.
Non Technical Outcomes:
 This internship helped me enhance my communication skills.
 Develop time management skills.
 Improved my writing ability.
 Understand the interactions between different departments and also between workers and managers.
 Learning to work in a group to achieve a common goal.
