1. INPLANT TRAINING
CHENNAI PORT TRUST

2. Introduction
Chennai Port, formerly known as Madras Port, is the second largest container
port of India.Over the period,the port has become a hub port for containers, cars
and project cargo in the east coast of India.Chennai port is the second smallest
in the country measured by surface area, encompassing only 274
hectares.Chennai port area is divided into north, central and south zones and
fishing harbours.The port has 26 alongside berths, including 21 deep-drafted
berths and 2 oil jetties, in the 3 docks, viz., Dr. Ambedkar Dock, Satabt Jawahar
Dock, and Bharathi Dock.
The total port roads run to a length of 27.5 km with a minimum width of 6 m
and a maximum width of 26 m. The port is served by the Chennai
Beach railway terminus in the Chennai Railway Suburban Newtwork of
the Southern Railway, chiefly handling suburban trains on the Chennai Beach-
Tambaram section of the Chennai Suburban Railway Network. .
Crude is transported from oil tankers berthed at the port through a pipeline and
then by road or rail.Since 1969, the port is connected to the Chennai Petroleum
Corporation's (CPCL) refinery in Manalii via a 30-inch-diameter pipeline
running for a length of 17 km.CPCL is planning to replace this with 42-inch-
diameter pipeline at a cost of ₹ 1,260 million along the proposed Quadrilateral
Road Network from Chennai Port to Ennore-Manali Highway.However, citing
threats to habitation, the government has refused clearance to the project.
Diesel Locomotive
The backbone of the transportation of cargo intra-port is the diesel locomotive.It
runs on heavy duty batteries.Each battery is of 8V.There are 8 batteries in a
single section.One cell provides 2V.So 4 cells are combined to form a

3. battery.The electrolyte mainly consists of distilled water and an acid medium in
the proportion of 3:1.An insulator tub is used for mixing the electrolyte.A
hydrometer is used for the wellness of the battery , for specific gravity
measurement.An auxillary generator is used for charging these batteries .The
electrolyte is poured after 48hrs into the cell.
Two high torque DC motors are used ,one on each side of the bogey.The supply
is thus used to run these 4 motors.A traverse is used to repair the engines which
runs on a motor which is used to rotate or accelerate the engine.
There are 8 diesel electric locomotive; 7 of which has a capacity of 700HP and
1 has a capacity of 1400HP.These locomotives are mainly used for cargo
handling.
Electric Cranes
Electric cranes are used for moving equipments,loads from and to the
containers.Also they are used in transporting cargo and other items to and from
ports.The following are the major functions that are involved in cranes
 Hold / Close
 Slew
 Luff
 Travel
Four ropes are present in the crane to perform the hold and close
operation.Solid cargo shifiting is done directly with the help of the four ropes
directly. For loose cargo such as sugar,potash,fertilisers etc. grab is used.
Ropes 1&4 are used to hold the cargo.Rope 2 is used for upward and downward
movement of the luff.Rope 3 is used to open and close the grab. Electric cranes
have specifications and rated value of equipments for each function.

6. A three phase slip ring induction motor is used for higher torques.Due to
this,speed control is possible.Four knotches is used as starter (Resistance
starter).A timer is set for moving between the 4 knotches to avoid motor strain.
Safety devices such as limiter,timer,OLD etc are used for the working of the
cranes.The circuit breaker called MCCB (Moulded Case Circuit Breaker ) is
used for disconnecting the supply from the element.
FCSS
FCSS is the section where the detailed parts of the ship is entirely seen in
pratise.The most interesting section of the entire port trust consists of 3
generators which are powered by diesel.Residual magnetism is present for self
excitation.It can be of either type, rotating field or rotating armature.Carbon
brushes are not required in rotating field.2V is the maximum value of voltage
for each cell in the battery.Dil. Sulphuric acid is used as an electrolyte. The
power factor of the system is kept high so as to improve the efficiency of the
generators.Synchronous generators or capacitor banks are used to improve the
power factor from lag to lead.
Ratings of alternator :
 Power : 75 Kva
 Voltage : 415V
 Current :104.4 A
 Speed : 1500 rpm
 Frequency : 50Hz
There are multiple gauges such as the pressure gauge , water level gauge ,
power level gauge etc.The pressure gauge is used to maintain the pressure that

7. is experienced.The power level gauge is used to denote overload or
overpower.There are two ways by which the ship gets power.
It gets its power either from the generators or the plug pits.The power supply is
connected to the alternative before switching off the current supply to ensure
continuos power.The generators are used to supply power when the ship is off
the docks and under any emergency situations.The plug pits supply power when
the ship is at the dock.The entire system is shut down after removing both the
powers supply.Propellsion is also done with the help of shafts
coupled.Commands are used in order to dictate the direction of the ship.
 Starboard – Right
 Port Side – Left
 Astern – Reverse
 Ahead – Forward
With the help of the generators salvaging fire fighting and other applications are
performed.
33 kV Substation
The substation uses 2 feeders mainly.Each substation has a step down process
of 11kV to 440V. “ANEX” is the name of the feeder that is used in the
distribution.Each substation has its own acronyms ie., SQ-1 is for South Queue
Substation.The various classifications of the transformer are
 Based on “Cooling”
 Air cooling
 Oil cooling
 Air Forced Water cooling

8.  Water Forced Air Cooling
 Based on “Core”
 Shell type
 Core type
 Berry type
 Based on “phase”
 Single Phase
 Three Phase
 Based on “Winding”
 Single winding
 Double winding
 Based on “Connection”
 Star-Delta (For generation)
 Delta- Delta (For transmission)
 Delta-Star (For distribution)
 Star-Star (For utilisation)
Basics of transmission and distribution , electrical machines , circuit theory ,
protection and switchgear , measurements and instrumentation were studied.
JD Electronics
JD electronics basically consisted of audio and visual biasing.Navigation lights
by artificial ports lead to channel biasing.UPS,Stabilisers,Inverters come under
the same.Channel boyce is a way that helps a ship to reach the port.Two colors

9. mainly are used for channel boyce namely green and red.Green is used to depict
the Shore Side whereas the Red is used to denote the sea side.
A 12V battery is used to operate these lights.These lights are of flashing nature
which is performed with the help of a 555 timer.The lights are switched ON for
1 second and are switched OFF for 3 seconds.The battery is charged with solar
energy which makes it efficient.A single plate in the battery is rated as 15A.The
surveillance is done by 360 degree rotatable,zoom-in and zoom-out type
cameras.This secures safety for transport of goods without any mismatch.Other
features include time-lapse recording,surveillance mode via motion and audio
detection sensors.
Conclusion
The above mentioned inplant training that I have undergone provided me with a
great opportunity to know about the various aspects of the industry.The
efficiency of practical knowledge cannot be compared with theoretical
knowledge at all.
It was not only knowledgeable but also exciting to get inside and board the
ship.Experience becomes power and knowledge is the root for it.
