ships systems

Question 1

sanitary

Answer 1

collect process and hold sewage ,grey water. and ground food waste from around the submarine and discharge them overboard. your 4 tanks are food waste sewage grey water and sanitary.operated by the lcp on scc using pms. you’ve got two discharge hull valves are san 601 (in ems) and san 602 (in ems) and san 618 (control room behind smcs)

Question 2

fresh water system

Answer 2

fresh water system is split into two separate sections hot and cold .water is supplied to the hot water tank (located fwd in ems) where it’s controlled at 71’C this hot water is then supplied to domestic services.ur fresh water tanks are located 3 deck port side no1 is outboard of air purification and 2 is outboard of cool and cold rooms

Question 3

ro plants

Answer 3

located in feed pump flat they convert sea water into fresh water by a way of reverse osmosis they draw sea water from the o comp tanks

Question 4

electrolyser

Answer 4

provide necessary oxygen to maintain the subs atmosphere and hydrogen which is converted to alternativ which is suitable for disposal overboard

Question 5

scrubbers

Answer 5

they use a chemical called amine the air we don’t wnat is drawn into the scrubber and is mixed with a amine spray absorbing the co2 the cold and purified air is put to the ventilation system and then the stuff we don’t want is either discharged overboard or to the gmp. there located in air purification compartment and operated by the sqep members of the fwd me staff

Question 6

burners

Answer 6

use a catalytic reaction that burns the carbon monoxide to produce co2 hydrogen and hydrocarbons. the co2 re enter the atmosphere where it’s removed by the scrubbers the h2 is turned into water vapour and the hydrocarbons are turned to co2 and h20. there located in the air purification compartment and operated by the fwd me staff

Question 7

gmp

Answer 7

mixes h2 and co2 because there gases and make a lot of noise when discharged overboard so they turn it into methanol as it’s quieter as it’s a liquid

Question 8

cams unit

Answer 8

just monitors the atmosphere and is located in the health physics lab

Question 9

apds

Answer 9

monitor the air for radioactive contamination and are located in engine room ,switchboard room which monitors the rc and 1 deck lobby that monitors fwd

Question 10

Question 14

chilled water plants

Answer 14

1 2 3 on freon flat provide a cooling medium for the chilled water system

Question 15

chilled water pumps

Answer 15

all 3 located behind chill water plants
circulate the chilled water around the chilled water system
