I have been given the task of designing a fire protection system for fixed roof fuel oil storage tanks. Tank details are as follows:

 

Diameter    = 58 m

Height        = 13 m

Product      = Fuel Oil (Class III)

Flashpoint = 70 C and above

 

Going through several forums, I have observed that in industrial practice for tanks storing liquids having flash point greater than 100 C use of foam system is often not recommended due to low vapor content being formed & danger of boil over, standards such as IP-19 also give vague hints of such practice. Following are my queries for this scenario:

 

i) whether i should install a fixed foam system?

ii) if no foam system is to be used what other alternative is to be used for fire protection/extinguishment?

iii) if water is to be used for control of burning/extinguishment, what application rates and to which surfaces should the water be applied to (roof surface, shell surface or both)?

 

I have already studied several standards such as NFPA 30, NFPA 15, IP-19, API 2021, API 2030 but they only provide vague hints in such scenario. So any expert advice would be appreciated.
