Special Areas under MARPOL

                      In Annex I, Annex II, Annex IV and Annex V, MARPOL defines certain sea areas as "special areas" in which, for technical reasons relating to their oceanographical and ecological condition and to their sea traffic, the adoption of special mandatory methods for the prevention of sea pollution is required. Under the Convention, these special areas are provided with a higher level of protection than other areas of the sea.



                     Annex VI establishes certain sulphur oxide (SOx) Emission Control Areas with more stringent controls on sulphur emissions and nitrogen oxides (NOx) Emission Control Areas for Tier III NOx emission standards.

Special areas under MARPOL are as follows:

Annex I: Oil
  1. Mediterranean Sea
  2. Baltic Sea
  3. Black Sea
  4. Red Sea
  5. "Gulfs" area
  6. Gulf of Aden
  7. Antarctic area
  8. North West European Waters
  9. Oman area of the Arabian Sea
  10. Southern South African waters
Annex II: Noxious Liquid Substances

  1. Antarctic area
  1. Baltic Sea
Annex V: Garbage
  1. Mediterranean Sea
  2. Baltic Sea 
  3. Black Sea
  4. Red Sea 
  5. "Gulfs" area 
  6. North Sea 
  7. Antarctic area (south of latitude 60 degrees south) 
  8. Wider Caribbean region including the Gulf of Mexico and the Caribbean Sea 
  1. Baltic Sea (SOx )
  2. North Sea (SOx)
  3. North American ECA (SOx and PM)(NOx)
  4. United States Caribbean Sea ECA (SOx and PM)(NOx)

Boiler Scale Formation

Boiler Corrosion

Galvanic Corrosion Can occur due to Oxygen attack or contact of two dissimilar metals in an electrolyte (eg: Copper + Steel). Oxygen Attack (Pitting Corrosion) At the Anode: Metal goes into solution               Fe ⟶ Fe 2+ + 2 e -               OXIDATION At the Cathode: Oxygen is reduced           ½ O 2 + H 2 O + 2 e - ⟶ 2 OH -             REDUCTION The variables pH, temperature and the concentration of oxygen affect the rate of corrosion. To avoid this alkaline conditions are maintained in the boiler. Oxygen reacts with iron to give ferric oxide (rust) Fe 2 O 3 which will not protect the metal from further attack and metal is continuously dissolved. 4Fe + 3O 2 → 2 Fe 2 O 3 Hematite (ferric oxide) Oxygen corrosion is usually...

Analog Addressable Fire Alarm System

Main Panel Block Diagram The fire alarm system continuously monitors the detectors. Detectors are divided into zones. (Using Software configuration file in the base board). Detectors are connected to the system through loops. (physically) The Loops are connected to the loop boards. Each Board can have 3 loops. Each loop can have 254 detectors. (Depending on the address size) Each Loop has an address and each device has an address given using DIP switches. (These are stored in the Software config file) Devices send digital data packets containing the Addresses and the Data. The digital data packets are sent digitally using analog signals through the twisted pair cables. ( Analog Addressable Signals ) ID address on DIP switches All addressable loop units must be given an address between 1-254 to be operational. The loop units located on the same physical loop must all have unique addresses. The address is set by a 8 pole DIP switch located on each addressable unit...
