26th April 19
Prathista Bhavan
External: Bald guy with specs, winks a lot.
Internal: Don't know.
First Attempt

Safety

*IMSBC code, explain what is there in it.
*Draw midship of bulk carrier showing cargo hold and name and show strengthening members in drawing.
*Draw Torsion box, how it is connected to ship, how it is strengthened.
*Lifebuoy, location, attachment, length of lifeline.
*Watertight doors regulation.

Electrical

*Single phasing, how you will come to know in watch?
*Motor not starting when pressing button, reason and further action.
*Generator started but no voltage is showing in msb, reasons.
*Starter panel maintenance, reasons why maintenance is required.
*Types of fuse, how it is classified.
*Name types of starters, why to use star delta, (expecting formala).
Decider: Difference between 3phase 3 wire and 3 phase 4 wire.
Decider2: Draw Dol starter circuit ( both power and control)

Motor

*Engine specs.
*Manual desludging of purifier, complete desludging procedure ( how it happens)
Pilot valve construction and working.(drawing expected)
*Temp of one cyl rising, reason, what will be result of it, what will you do if you are in watch
*Main advantages of pulse turbocharging.
Decider: Oiler called you and told gen cyl head is ready to lift, what all things you need to check before lifting.


*What is pipe schedule.
*Different ways of extracting studs, draw how stud extractor looks.
*Types of threads, standards.
*Welding defects, lap welding, Why tig welding.
*Lube oil properties of 4 stoke crankcase oil.
*Types of Boiler tubes, too much cross questions.
*Compressor v/vs part names.
Deciders: Checks and any measurements before boxing up shell and tube type heat exchanger, Draw and show fwg condenser plates and how movement of water and vapour is happening,

Wire drawing effect

Wire drawing effect : It is erosion or scoring of valve seat and disc material of the valve . Causes : 1. Due to differential pressure across the valve . 2. Thermal and mechanical damages . Effects : Valve is unable to isolate the line and fails in sealing . Gas and liquid will leak from the wire and scratch like groove .

Difference between Attemperator and De-superheater

Attemperator are fitted in order to keep the steam temperature in the final stages of the superheater within certain desired limits . This is done for two main reasons . 1. The most important is the protection of the superheater tube material from the effects of overheating. *Mild steel superheater tubes tubes should not be subjected to steam temperatures in excess of 455℃. 2. The formation of bonded deposits on superheater tubes can be reduced if steam and gas streams within certain temperature ranges are prevented from coming into contact of each other. De-Superheater is used to reduce the temperature of a quantity of superheated steam and make it suitable for used in auxiliary services requires low temperature or saturated steam . *The reason for doing this way rather than by taking the saturated steam direct from steam drum , is to protect the superheater , these must be protected against overheating under all conditions of load by circulating steam through them . *Al...
