SEEMP SHIP ENERGY EFFICIENCY MANAGEMENT PLAN MEO CLASS 4

  SEEMP     SEEMP is designed to achieve better energy efficiency Ship efficiency management plan provide a mechanism to improve the energy efficiency of the ship in a cost effective manner. SEEMP made mandatory for all the ship as per MARPOL   SEEMP divided into two parts     part A :  ship specific measure that have been adopted by company to improve energy efficiency.  FUEL EFFICIENCY OPTIMIZATION WEATHER ROUTINE DRAFT AND TRIM OPTIMIZATION PROPELLER AND HULL CLEANING SPEED OPTIMIZATION TIME MAINTENANCE PART 2: Applicable for the all ship of 5000gt and above. Should collect the data .   TYPE OF FUEL CONSUMED  AMOUNT OF EACH FUEL CONSUMED DISTANCE TRAVELED HOURS UNDER WAY.

BOILER MOUNTINGS

  Internal mountings. O gee ring  Demister Ring and distributor  Fusible plug  External mountings   Pressure gauge Steam stop valve  Auxiliary steam stop valve  Bottom blow down valve  Scum blow down valve  Safety valve  Salinometer valve  Feed checker valve  Gauge glass  Vent 

Difference between smoke tube and water tube boiler.?

  SMOKE TUBE BOILER   LOWER RATE OF EVAPORATION LOW PRESSURE BOILER  LESS COMPACT SIZE  GAS PASSES THROUGH TUBES  USED FOR LOW STEAM  DEMAND AREA  NORMAL QUALITY OF WATER CAN USE  MORE STORAGE CAPACITY OF STEAM. WATER TUBE BOILER HIGH RATE OF EVAPORATION HIGH PRESSURE BOILER  COMPACT SIZE USED FOR HIGH DEMAND AREA WATER QUALITY SHOULD BE GOOD  LOW STEAM HOLDING CAPACITY.

BOILER GAUGE GLASS BLOW THROUGH

  GAUGE GLASS BLOW THROUGH SHUT THE STEAM SIDE VALVE  SHUT THE WATER SIDE VALVE  NOW OPEN THE DRAIN VALVE  NOW GAUGE GLASS BECOME EMPTY. NOW OPEN THE STEAM SIDE VALVE ,IF STEAM COME OUT WITHOUT ANY DEFICIENCY WHICH MEANS STEAM SIDE IS CLEAR . NOW CLOSE THE STEAM SIDE  OPEN THE WATER SIDE, IF WATER  WILL COME OUT WITHOUT ANY DEFICIENCY WHICH MEANS  WATER SIDE IS CLEAR. NOW CLOSE THE WATER SIDE  AND CLOSE THE DRAIN VALVE. NOW OPEN THE WATER SIDE FIRST, WATER WILL RISE AND FILL UP THE GAUGE GLASS. NOW OPEN THE STEAM SIDE STEAM WILL COME INTO GAUGE GLASS AND SHOW THE EXTRACT LEVEL OF INSIDE  BOILER WATER. Notes SURVIVER MAY ASK YOU OPEN WATER SIDE FIRST  (If we open steam side first gauge glass will breake because of lantern heat.)

STARTING OF IG SYSTEM& IG PLANT PARTS AND FUNCTIONS

  Starting of IG System Boiler should be on. Set the line for deck seal pump  Set the line for scrubber pump Set the line for O2 analyser. Set the line on blower, Now put the breaker to on position.  Ig starts & running. Function of ig parts. Scrubber tower: Gas will be cooled down to working temperature. Solid particles will removed  Soluble gas and Sox and carbon gases set mixed with water and draun out. Demister    Demister made on wire gauge. Act as a water absorbent. It Moisture will removed and gas will br dry. Blower There will be two blower . One for stand by another one will send the gas freeing to cargo tank. Pressure regulator valve  It regulates ig pressure asper discharge rate of cargo and maintain always  positive pressure inside the tank. O2 analyser . It will analyse the oxygen content flowing with gas  Temperature recorder. If ig gas above 57°c it will not allow the gas to cargo tank. Bleed valve  Its a three way valve  .if o2 content is High in ig gas it will open

Safeties Safety pin Relief valve

PORTABLE EXTINGUISHERS WATER TYPE FIRE EXTINGUISHER

  WATER TYPE FIRE EXTINGUISHER Used for classA and ClassB fires like (wood, paper) Should use Minimum 9 to maximum 13.5 lit capacity of water as per the solas regulation. 74g of cg cartage should be used  Duration 60 seconds lenth of the 6 meter  Pressure will difference as per the capacity and weight of the cylinder. Safeties Relief hole, and safety pin  Maintenance Weekly : Check and clean the nozzle and seal. Monthly : Check internal and external  And co2 cartage and safety pin and weight Yearly Pressure test @ 36 bar

AIR COMPRESSOR MANUAL STARTING PROCEDURE

Air compressor starting procedure manually. Change over the switch to manual position on the switch board. Check the L.O sump level and condition. Open the moisture drain valve.  Open the compressor discharge valve and charging valve of air bottle. Open cooling water system valves. Turn  compressor flywheel by hand (one turn) Now Start the motor, after that  draining the moisture and shut the drain valve. Check the motor ampere consumed. Check the pressure gauge readings. Frequently drain the moistures. Once the charging full, open drain valve and stop the compressor.

PURIFIER OVERFLOW REASONS

Reasons for purifier overflow Incorrect purifier disc size [Inside diameter too large] Too low fuel oil temperature Too much rate of throughput  Too much sludge inside the bowl Low speed (rpm) of bowl rotation Sealing water failure Operating water failure Worn out main sealing ring. Important Note:   surveyor will ask you the following cross questions Q1. what is throughput?  ANS: Purifier feed (inlet) Q2. what is the meaning of overflow? ANS: Overflow means oil leaking to water side or water leaking to oil side due to failure of interface between these two liquids. Q3.How will you come to know your purifier is overflowing when you are being in ECR? ANS:  Purifier abnormal alarm will come Sludge tank high level alarm will come

Air compressor

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

Image
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?

  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
