3. What does the ISGOTT guide say about measuring and sampling of inerted tanks? Answer No.3 -  I will try to answer this question according ISGOTT guide book (International Chamber of Shipping). Third edition 2002, about measuring and sampling of inerted tanks, that is tank washing may be carried out in one of the following atmosphere   INERT INERT –   –   an an atmosphere made incapable of burning by the introduction of inert gas, 

and thereby reducing the over all oxygen content non exceed 8% for the purpose of this guide

   NON INERT –  INERT –  an  an atmosphere which is undefined



SOURCE of INERT GAS -  Nitrogen supplied by the ship it self can exther be produced on board as needed from  pressure swing adsorption or membrane separation generator or can came from liquid nitrogen or compressed nitrogen stored on board. If the nitrogen supply system is located in a class a machinery space.

4. What precautions are recomended by the ISGOTT guide when loading loading static accumulator oil? Answer No.4 -  The overall loading rate should be selected so as to ensure a maximum product velocity of 1 m/s into any tanks, assuming even distribution of cargo between tanks -  Possible different flow distributions in to different tanks should be considered and the  best efforts should be made to esure equal flow distribution between cargo tanks

-  Not more then 6 cargo tank should be loaded at only 1 time  

 

-  Tank inlet valve be used to control cargo flow in the initial loading phase their use will reduce the crossectional area of the inlet resulting the increased tanks inlet velocity and greater turbulence and mist formation. If it necessary to throttle valves in order to control flow rate, this should be done upstream of the tank valves

5. List all items coded “R” in the ISGOTT ship/shore safety check list.  list.  Answer No.5 Items in coded thrown overboard within 3 miles or o r nearest land and oil in land waters you cant throw anything overboard.

  Within 3-12 miles of shore, garbage if not ground in 1 inches. Paper,rays,metal,glass

Write short notes on inerting and gas freeing procedures on board your ship. Answer No.9 A.  Inertine Gas To make oxygen content on our tank or each tank No more than 8 % as Required oxygen content of our tank less than 5 % . As per ISGOTT   Use of inert gas on my vessel are, a. Boiler distributed steam to the Scrubber.  b. From the Scrubber it makes to Deck Water Seal. c. And then from Deck Water Seal, It going to Every Each Tank.

In the replacement of hydrocarbon vapours in a cargo tank with fresh air. A tank or compartment is said to be gas free when sufficient fresh air has h as been introduced to lower the level of flammable..  

Methods or gas freeince a.  By introducing fresh air water through the inert gas g as line after the tanks atmosphere has been brought down to below the oritical dilution line in the flamibility diagram  b.  By means of portable blowers which are either steam or water driven hydraucally or preumatically operated c.  On old tankers-wind sails ware used to gas free the tanks.

If so look at the manual and describe in detail their operation, their pressure setting and how they are arranged on board your ship. Supplement your answer with sufficient diagrams. Answer: Yes , I have Details operation : The pressure vacuum relief valve is maintains a tight seal until system  pressure or vacuum exceeds the set pressure of the valve. When overpressure ov erpressure occurs the weighted pallet lifts, breaking the seal between the seat and pallet, allowing vapours to  pass through the orifice and relieving the pressure or vacuum buildup. The valve v alve reseats upon relief and remains sealed.

Answer: On my vessel, we often to use portable blower if we we want to load the different cargo, we have to cleaning all tank with tank cleaning machine or butter worth, after that we didn’t  

 

forget for freeing the gas of tank by portable blowers. Portable blowers powered. By air, steam and water of deck from engine room. We after to use tank cleaning pump for getting the salt water to be used by portable blowers. Portable blowers are usually use on ship when only one tank has to be as freed this is a chieved by isolating the tank from inert gas main.
