Mohon pencerahannya mengenai Back-up Fire Water Pump. Di perusahaan saya bekerja berniat mengganti Back-up Sea Water Fire Pump yang sudah lama dimakan usia dengan Fire Pump yang baru. Apakah cukup didesain dengan NFPA-20? atau ada standard lain untuk Back-up Seawater? atau saya cukup ganti dengan spec Fire pump yang sama?

Subject yg menarik sekali untuk diperbincangkan praktisi di safety. I duno the right answer for this situation. but safety was not process related issue. my thinking during fire, people want all available water source to used at once.
So nothing to do with the pump sized say 3 x 50% rated capacity. if you want one , two, or three pump then be it. the only think you should consider was maintenance related issue, the pump must available at all time, from here people consider independent power source separate from plant electricity. back to maintenance related issue was your statement, habis dimakan usia, actually if we back to root of the fire pump in the first place (should be available at all time) we should not have the issue in the first place right pak ????.
Now the discussion spilling to other issue , maintenance ????, that the main problem in our industry, people just interesting on production,production, production. Maintenance anak bawang how about that ???.
Any way pak. in my opinion if you have opportunity to buy , i think i would not use 30 years old specification. i think I would like to have a modern specification where i can feel save and sleep well whithout worrying about part, after sales services and many other beautiful thing that offered by modern industry.

Yup pak Roeddy.
Actually only for back-up while both our main fire pump failed, and need more water supply.
Our back-up sea water fire pump was 15 years old. And till now it was never operated. We have 5 fire pump (1 jockey, 1 main pump, 1 diesel pump, and 2 back-up sea water pump). Both sea water pump was old coz we’re never operate those pump even for warm-up. Yup, as you said that people just interesting on production. hehehe…. hope my boss doesn’t read this mail.
Now, I wanna re-desain those pump as NFPA-20 requirement. is it right? or there’s a spesific standard? coz I’d like to have the new one. hehehe….

Dear Pak Arif,
I am not a good practitioner on this subject, you know fire water system was only made once when we build the facilities so its a rare opportunity to get on hand. so other member i am sure will help you with their tough
But i guess dealing with this situation will need more carefull reference, not just single reference to consult. there were a lot of excellent recom. at a mater of fact to me NFPA spreading out their recommendation in various volume. duno if this was their comercial politic so people buy their book ha ha ha .
Several volume that i remember deal with this was nfpa 13,14, 15, 30 and various nfpa suplement, other reference api 2510, IRI,were closely related with yr requirement. i guess the 20 was dealing with water source ???? i might be wrong on this
some write up in uk now pushing to use a fog tipe spray (need very high pressure and special nozle to do this).
One thing i do know from operational perspective working for offshore. the suction line was blocked with fouling/marine growth/teritip. this happend in area where the sun have a good penetration to down depth. so at time the need the water they were very surprised they lost the water.so important that surveilance to probe the healtines the system were in place. i dont think old engineer in the past put that in equal proportion specialy the system that designed by the contractor, their objectif was completed the job, commisioned , handover to owner then move on to new project. we then inherited with the crap that they left.
