Test procedure for IGS alarms

Blower Power Fail
Switch off the power supply for the required blower from the main switchboard.

Burner Fuel Oil Pressure Low
Shut the valve to PS-185. This valve is on top of the scrubber tower.
Open drain screw and drain the fuel in the line.

Emergency Stop
Press the emergency stop button. This is in CCR.

Burner Flame Failure
Shut photocell – BE 200 valve. Location of valve is on top of the scrubber tower.
Cooling Water O\Board – O. Bilge Tank Changeover V\V to be activated.

High I.G. Gas Temperature
This test is carried out with the help of temperature calibration unit.
Remove thermocouple from IG outlet line.
Put it in calibration unit and raise the temperature.

Scrubber Water High Level
Disconnect cable from LS193, which is near level sensor on scrubber unit.

Loss of Power
Remove relay from CCR IG panel.

JCW Pressure Low
Close valve # 50.
This is JCW inlet valve on scrubber tower.

Low Deck Seal Water Pressure
Stop running deck seal water pump.
Stand-by pump will start and stand-by pump started alarm will sound.
Deck seal water pressure low alarm will sound.

Deck Seal Water Level Low
Stop deck seal water pump, which is in use.
Open deck seal drain valve.

Instrument Air Pressure Low
Shut off air to PS183. Location of this valve is on top of the scrubber tower.
Drain air by opening drain screw.

Low Scrubber Water Pressure
Throttle scrubber water inlet valve 164.
This valve is on the scrubber unit.

High IG Pressure
Shut inlet valve on the pressure transmitter.
Pressure transmitter is on the main deck, below IG line near #6 stb tank.
Disconnect transmitter inlet line and lightly blow air in the line.

High Oxygen Content
Change setting in CCR I.G.S. Panel.

Main engine interlocks

Interlocks are provided so that the engine can be started or reversed only when certain conditions have been fulfilled. When there is a remote control of engines, it is essential to have interlocks. This reduces the possibility of engine damage and any hazards to the operating personnel. Turning gear Interlock . This device prevents the engine from being started if the Turning gear is engaged. Running Direction Interlock . This prevents the fuel from being supplied if the running direction of the engine does not match the Telegraph. Starting Air Distributor in end position . This prevents starting from taking place if the shifting of the Distributor has not been completed. Main Lube. oil pressure, Piston cooling pressure, Jacket water pressure, and important parameters must be above the required minimum. Auxiliary Blower Interlock . The Auxiliary Blower is provided in case of Constant pressure turbo charging. Air Spring pressure Interlock . In case of the present generation

Why is a man hole door elliptical in shape?

Any opening in a pressure vessel is kept to a minimum and for a man entry an elliptical hole  is lesser in size than the corresponding circular hole. More over it is prime concern to have a  smoothed generous radius at the corners to eliminate stress concentration. Hence other  geometrical shapes like rectangle and square are ruled out.  To compensate for the loss of material in the shell due to opening, a doubler ring has to be  provided around the opening. The thickness of the ring depends on the axis length along the  dirrection in which the stresses are maximum and the thickness of the shell. It is important to  align the minor axis along the length of the vessel, as the stress in this direction is  maximum. Longitudinal stress: Pd/2t where P= pressure inside the vessel, d= diameter of the arc, t=  thickness of the shell plating  Circumferential stress: Pd/4t  More over a considerable material and weight saving is achieved as minor is along the  direction of maximum stress.
