(S700) the hypochlorite (S) concentration if the amount of seawater injected is an appropriate flow rate in step S600;
Confirming whether the concentration of hypochlorite (S) detected in the step S700 is an appropriate concentration (S800);
(S810) adjusting the hypochlorite (S) concentration to 6 to 8 ppm by controlling the neutralization agent (N) injection if the hypochlorite (S) concentration is excessive or under-detected in step S800; And
And terminating the driving if the concentration of hypochlorite (S) ascertained in step S800 is an appropriate concentration (S900).
The step S210 includes generating an alarm at the alarm signal unit 420 (S220);
Confirming whether the error is due to the failure mode (S230);
If it is determined in step S230 that the failure mode is selected, step S240 is performed to calculate an RPN (Risk Priority Number) index using an FMEA (Failure Mode and Effect Analysis) technique.
If the RPN index is calculated in step S240, step S250 of estimating the failed part is performed. And
Further comprising a step S260 of processing the failure of the faulty component estimated in the step S250.
If the fault mode is not caused by the fault mode in operation S230, the fault mode probability of the fault tree is calculated by an FTA (Operation S231);
Estimating the type of the failure mode with the failure mode probability calculated in step S231 (S270); And
Further comprising a step (S280) of checking whether the kind of the failure mode estimated in the step S270 is due to the failed component,
If it is determined in step S280 that the faulty part is used, the method returns to step S240.
