WHAT ARE THE REASON FOR PURIFIER OVERFLOW? INCORRECT DISC SIZE  TOO HIGH FUEL OIL TEMPERATURE  TOO MUCH FEED RATE  TOO MUCH SLUDGE I SIDE THE BOWEL LOW RPM OF THE BOWL SEALING WATER FAILURE OPERATING WATER FAILURE MAIN SEALING RING WORN OUT. WHAT ARE THE REASON FOR VIBRATION ON PURIFIER? TOO MUCH SLUDGE BEARING FAILURE FAILURE OF FOUNDATION BOLT GEAR WORN OUT  UNEVEN TOUCHING WITH FRICTION CLUTCH MOTOR SPEED IS TOO LOW OE TOO HIGH. WHY WE ARE NOT GETTING ENOUGH RPM WHEN PURIFIER IS RUNNING? IMPROPER TOUCHING WITH FRICTION CLUTCH TOUCHING WITH BREAK EXCESSIVE SLUDGE IN SIDE THE PURIFIER BEARING FAILURE ONE PHASE POWER FAILURE MOTOR RUNNING OVERSPEED. SURVIVER WILL ASK YOU GOW TO CHANGE  THE PURIFIER HFO TO DO? REPLACE THE GRAVITY DISC  (WHICH IS SMALLER THAN HEAVY OIL) OPEN HEATER BYPASS VALVE  CLOSE THE HFO HEATER'S IN AND OUT VALVE  AND OPEN THE DRAIN VALVE OF HEATER. ( SOME PURIFIER DESIGN ONLY FOR DO WHICH WILL NOT CHANGEOVER TO HFO.) HOW WILL YOU ADJUST PURIFIER BOWEL HEIGHT? F

  FREE SURFACE EFFECT Definition of free surface effect?     When a tank or compartment partially filled with liquid, when a ship is inclined. liquid will moves along with ship's inclined  direction. which will reduce the stability of the ship. How to reduce free surface effect : Swash bulkheads  Pocketing Surface permeability Sluice valves  Swash bulkheads This types of bulkheads give some additional strength, Which are longitudinal  bulkheads which will restrict the flow of liquid when ship is  inclined   Pocketing  fill the tank fully which will reduce the free surface effect Surface permeability The object such as machineries, engine and piping systems prevent the moving water  shifting of wedge, these reducing the free surface effect. Sluice valves  The large slack tanks are cross connected with sluice valves, it will reduce  the flow of the liquid so that it will reduce free surface effect.

  Safety measures enhance to maritime security ISPS code Objectives of Ism code :  To discover the security threats and take preventive action against the security threats. And proper preventive measures are placed  Early and efficiently collecting the security level information, and share  the security information. Three levels of ism code  Level 1:  Minimum appropriate preventive security measures for all the time. Level 2:  Additional protective preventive security measures for period of time. Level 3:   Level 3 is High level protective preventive security measures for limited time. Level 1:  Deck over lightings. Crew photo identification  Visitors should be identified Regular patrolling will carried out. rooms which is not in use should be closed and locked by key. Certain area should be closed and locked by key Level 2   In additional to level 1 Oscillation search will carried out. Shore Delivery should be checked properly. Visitors will strictly assist. Cargo seals should be chec

 Fire control safety plan Location:   Entrance of the ship both sides.   On bridge.   On Engine control Room.    Ship's office. (In side the red colour container ) It will contain the details of all fire fighting appliances and its location. Importance of located outside: Other fire fighter came to our vessel. they will easily find out the extract location of extinguishers and  emergency escape route. It contains: Fire detection and alarm system Springer installation Co2 nozzle installation Location of all extinguishers EEBD location Ventilation system Details and location of escape route Life craft life Jacket immersion suit location Total number of fire hoses and nozzles   

What is Emergency Generator, Location and It's Regulations? Emergency Generator: Back up Electrical System in the event of main power supply failure. Within 45 seconds emergency generator should start and give power to emergency source.  Location: Emergency generator with it's switchboard is located in a compartment outside the engine room above the uppermost continuous deck and not forward of the collision bulkhead. Regulations: It should be above longitudinal continuous deck. It shouldn't be forward of the collision bulkhead. compartment should be accessible from the open deck. It should be able to start at 0°C in cold weather. Heaters should be provided (for cold weather, JCW system must be treated with anti-freeze agent) Fuel flash point shouldn't below 43°C. Fuel tank capacity should be last long for 18 hours. Two starting medium must be available.  Each medium should be capable to give three starts consecutively in 30 minutes without charged.   It should be capabl

  INCLINING EXPERIMENT    WHAT IS INCLINING EXPERIMENT? The initial metacentric height is determined by inclining experiment. after the ship is fully build or major changes in structure must do inclining experiment. WHAT IS METACENTRIC HEIGHT? When a ship is heels by an angle the center of buoyancy and center of gravity will moves laterally. if we draw the imaginary vertical line from, the new center of buoyancy it will cut the original vertical line that point is called metacenter , The distance between center of gravity G and metacenter is called metacentric height, INCLINING EXPERIMENT    place the special tool name STABILOGRAPH, placed the tool in forward and aft of the ship, four masses are placed in the each two will placed port and aft sides,  masses should be placed away from the center line. masses should moved one by one to port sides from stbd side, now move the masses from stbd side to port side one by one , finely placed two masses each sides, all movement of masses should
