STIFF SHIP AND TENDER SHIP and Difference between stiff and tender ship.

Stiff ship and tender ship

  STIFF SHIP

• When a metacentric height and righting lever distance is large,
• Ship have excessive stability
• Ship will come to its normal upright position very quickly when its heeled.

Tender ship

• When metacentric height and righting lever distance is very small. 
• Ships have less stability
• Ship will come to its  normal  upright position very slowly when its heeled.

DIFFERENCE BETWEEN STIFF SHIP & TENDER SHIP?

EPIRB EMERGENCY POSITION INDICATING RADIO BEACION

MEO CLASS 4

• self activating radio transponder 

• made of buoyancy material

• as per SOLAS min 1 should be carried, as per dg shipping 2 should be carried,

• battery storage life is 5 years.

• attached in bridge wings with HRU 

• it capable of flooding and automatically activated in the event of flooding.

• once it is activated it will continuously sends the radio signal at least 48 hours .

• it will send the code message via satellite. frequency is 406.5Ghz signal recived by the rescue coordination center, 

• EPIRB capable of send signal to 3NM 

• some of EPIRB have in build GPS which accuracy is  located to  +- (1- 50) meters 

• cospassart satellite 

•   signal will update every 20 mints

INDICATOR DIAGRAM

 indicator diagram

•  At the same time it will indicate pressure and the position of piston.

Purpose:

• To indicate the power developed in the system (cylinder).
• To indicate the pressure maximum (Pmax) and compression pressure
• To find the exhaust and scavenging condition
• To evaluate the combustion process.

 

Types of indictor diagram.

• Draw card 
• Power card
• Compression card
• Light spring diagram

DRAW CARD 

 

• Its used to find the Pmax & Pcom accurately
• With this draw card we can find the ignition delay,fuel pump timing and after burning and the loss of compression.
• Its 90° out off phase with piston movement.

POWER CARD

• Its used to find the indictor power.
• And to find the peak pressure and compression pressure.
• Its in-phase with piston with fuel on.
• It can be find by planimeter.

COMPRESSION CARD

• Its used to find the compression pressure.
• Ans the cylinder thickness.
• Its in-phase cut off fuel and reduce rpm.

LIGHT SPRING DIAGRAM

• Its used to find the pressure variation in the cylinder. With respect to scavenge and exhaust manifold.
• It is in-phase with light spring in fuel on .
• It will show the chocks in scavenge manifold and exhaust valve chocks and less air.

SURVIVER MAY ASK

Why is not possible to take power card in 4-stroke engine?

• 4 stroke piston moves 2 times to TDC in one cycle. So we can't able to take.

FOAMING / PRIMING AND ITS EFFECTS IN BOILER

FOAMING

Formation of thick layer of steam bubbles.

PRIMING 

Its the condition of large amount of water carried over alone  with the steam 

EFFECT OF FOAMING AND PRIMING

• water hammering
• Contamination
• Scale formation
• Fluctuation in water level

Function 3

 

FREEBOARD AND ITS PURPOSE

 

 Distance measured from water line to top of the deck.

 Purpose- 

 Its the protection and closure opening such as hatchway, door ways, ventilation, air pipes, scuppers, and prevent the water accumulation. 

 

Chamber

 

 The transverse cure of the deck from center line to side shells 

 To drive the water outside of the deck ..

Tumble home 

In some ship's side shells are slightly inverted facing to centre line this is called tumble home.

Sheer 

 The curvature of the deck from mid ship to forward and aft .

Stiff ship 

Its the condition of ship's metacentric height and righting level is large. At any angle resistance to rolling.

Tender ship

 

 When metacentric and righting lever both distance is small  At any angle ship will roll.

Pounding

 When a ship is sailing in heavy weather bow rises above the water because of waves, bow will completely out from water and when it will come back  and hit the water with heavy impact its called pounding.
