ZEESHAN AHMEDZEESHAN AHMED, Marine Engineer, Marine Engineer. After doing FSc(pre-engineering) . After doing FSc(pre-engineering) from PAF(fazaia) intermediatefrom PAF(fazaia) intermediate college Lahore cantt. I joinedcollege Lahore cantt. I joined Pakistan Marine Academy andPakistan Marine Academy and choose Marine engineering branch. choose Marine engineering branch. Two years of training at academyTwo years of training at academy (practical + theoretical) (practical + theoretical) we learned a lot of thing like CNC we learned a lot of thing like CNC (computerize numeric code), trained (computerize numeric code), trained on various models (like control valve, solenoid valve, flow meter, refrigeration system, on various models (like control valve, solenoid valve, flow meter, refrigeration system,

ETC . After two years, we joined 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 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 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 (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 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 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 type heat exchanger gasket change, shell and tube Cooler Anode replacement and (Cont.)(Cont.)

One thing I 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 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 electrical application. So a marine engineer must strong in automation, instrumentation and control system. PLC (programmable and logic control) and SCADA (supervisory and control system. PLC (programmable and logic control) and SCADA (supervisory central access and data acquisition) are the upcoming technology that are using on 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 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 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.which is driven by Axial piston pump mounted on the Fly wheel.
