COLD IRONING

COLD IRONING

       COLD IRONING OR SHORE POWER OR ALTERNATIVE MARINE POWER (AMP) IS THE PRACTICE OF PROVIDING SHORE POWER TO A SHIP AT PORT. WHILE THE SHIP IS AT PORT ALL THE ENGINES AND GENERATORS SHUTDOWN AND THE SUPPLY IS TAKEN FROM THE SHORE FOR THE ENTIRE NEED OF SHIP

       THE TERM COLD IRONING IS CAME FROM THE COAL FIRED SHIPS ERA, ONCE THE COAL FIRED SHIPS WAS IN PORT THE SHIP IS CONNECTED TO SHORE SUPPLY AND THE BOILERS TO BE STOPPED AND THE LARGE IRON STEAM ENGINES  ALLOWED TO BE COOLED .THE PROCESS OF COOLING THE IRON BECOME COLD IRONING

      THE LOSANGELS AND CALIFORNIA ARE SOME OF THE PORT FIRSTLY IMPLEMENTED COLD IRONING OR AMP.AND IT IS ALSO REFERRED TO VESSELS OPERATING IN ALASKA

       THE THE COLD IRONING OR SHORE POWER IS FOCUSED TO REDUCE THE EMISSION FROM THE SHIPS BERTHED AT THE PORTS

ADVANTAGES OF COLD IRONING

1. REDUCE THE ENVIRONMENTAL IMPACT. RUNNING DIESEL ENGINE PRODUCES SOx, NOx , PRODUCE NOISE AND VIBRATION WHICH EFFECTS THOSE LIVING AND WORKING ONBOARD

2. COST EFFECTIVE, COMPARING TO RISING BUNKER FUEL COST GRID POWER IS CONSIDER ECONOMICAL

3. THE MORE STRINGENT ENVIRONMENTAL REGULATION SURROUNDING PORT AND COASTAL WATERS

4. MAINTENANCE CAN BE PERFORMED.,ENGINE RUNNING HOURS WILL BE REDUCED,THE MAINTENANCE SCHEDULE WILL INCREASE SO FREQUENT RENEWAL OF SPARES AS PER PMS WILL REDUCE,THROUGH THE SPARE COST CAN MINIMISE

         BY IMPLEMENTING COLD IRONING THE SHIPPING INDUSTRY WILL NOT CUT FUEL OIL COSTS ALSO CUT THE CO₂  EMISSION

DIS ADVANTAGES

1. COST OF INFRASTRUCTURE. THE PORT SHOULD INVEST HUGE AMOUNT ON POWER SOURCE,POWER CABLES,CABLE HANDLING SYSTEM,SWITCH GEAR TRANSFORMERS

2. THE CONNECTORS ARE INTERNATIONALLY NON STANDARD TO BE INTERNATIONALLY STANDARDIZED

3. THE VOLTAGE AND CYCLES ARE NOT UNIFORM ON SHIPS,SUCH AS 380V,440V AND 50HZ,60HZ,CONVERSION TO 50HZ TO 60HZ AND VICE VERSA RAISES THE COST

4. FAILURE OF THE POWER SUPPLY OR PROBLEMS IN THE TRANSMISSION TO WILL CAUSE BLACK OUT

5. POWER LOAD REQUIREMENT OF THE SHIP WILL VARY ON SIZE AND NO OF SHIPS IN PORT

6. THE REDUCTION OF POLLUTION ONLY OCCURS WHILE SHIP IS AT PORT
