After SIL classification, SIL verification is necessary to confirm if the SIF design and instrument model determination are safe enough to meet the target SIL. SIL verification consulting calculates the achievable SIL based on the current SIF design and compares the result with target SIL. Yokogawa safety experts are able to carry out this assessment for both low and high demand mode applications.
SIL verification consulting are usually executed twice, before instrument bidding and after final selection of instrument by bidding to avoid costly redesign and rework of the safety related instruments.
