  38. 38. 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), trainedon 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.)
  39. 39. Introduction (cont.)cleaning of SALT WATER tubes etc.) , MT Swat (major thing which I learn in Swat is howto dismantle head of main unit and copper gasket replacement with a minor facing defectwhich is found during overhauling which is filled and faced by Belzona) , MTLahore(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, MTKarachi (Dry washing of the main engine turbocharger with granules, water washing of IGFan of Inert Gas system, sludge removal of from purifier(centrifuge) etc., . One thing Iwant to added is that the trend in ship building is more toward based on electronic andelectrical application. So a marine engineer must strong in automation, instrumentationand control system. PLC (programmable and logic control) and SCADA (supervisorycentral access and data acquisition) are the upcoming technology that are using onmodern ship. The latest engine of MAN B&W is based on Camless technology. Chain isremoved ; fuel pump and exhaust valve actuation is control by hydraulic servo(lub) oilwhich is driven by Axial piston pump mounted on the Fly wheel.Regards,Z.A.
