2. IT IS THE ALLAH WHO SUBJECTED
THE SEA TO YOU.THAT SHIP MAY SAIL
THROUGH IT BY HIS COMMAND ,THAT
YE MAY SEEK OF HIS BOUNTY,AND
THAT YE MAY BE GRATEFUL
(Al-Quran Surat Jasiya 45: R12)

41. Author Introduction
ZEESHAN AHMED, Marine Engineer
. After doing FSc(pre-engineering)
from PAF(fazaia) intermediate
college Lahore cantt. I joined
Pakistan Marine Academy and
choose Marine engineering branch.
Two years of training at academy
(practical + theoretical)
we learned a lot of thing like CNC
(computerize numeric code), trained
on various models (like control valve, solenoid valve, flow meter, refrigeration system,
CPP propeller, Main engine model (TWO stroke), Boiler model (water tube)
……………………………….. in GEK (general engineering knowledge) lab,
Mechanical and physics lab, Engineering workshop. ETC . After two years, we joined
PNSC workshop for the training of ONE year Industrial training. That was also the
golden time where we learnt a lot of things at different shops as well as onboard
(repairing and watch keeping). I learn many thing on tanker E.g. MT Johar (learn how
to dismantle turbine rotor from casing and what are the precautionary measurement
while working on turbine, learn how to change the diaphragm(stationary blade) Plate
type heat exchanger gasket change, shell and tube Cooler Anode replacement and
(Cont.)

cleaning of SALT WATER tubes etc.) , MT Swat (major thing which I learn in Swat is how
to dismantle head of main unit and copper gasket replacement with a minor facing defect
which is found during overhauling which is filled and faced by Belzona) , MT
Lahore(About the DEAD MAN ALARM, Alpha lubricator for Cylinder Main Engine Unit,
Pump operation and watch keeping), MT Quetta(Auto load sharing of Generator Set, MT
Karachi (Dry washing of the main engine turbocharger with granules, water washing of IG
Fan of Inert Gas system, sludge removal of from purifier(centrifuge) etc., . One thing I
want to added is that the trend in ship building is more toward based on electronic and
electrical application. So a marine engineer must strong in automation, instrumentation
and control system. PLC (programmable and logic control) and SCADA (supervisory
central access and data acquisition) are the upcoming technology that are using on
modern ship. The latest engine of MAN B&W is based on Camless technology. Chain is
removed ; fuel pump and exhaust valve actuation is control by hydraulic servo(lub) oil
which is driven by Axial piston pump mounted on the Fly wheel.
