MiRO Circuits

There are several places in the application from where you can add a new Circuit, for example:

Circuit main grid

(Header bar)

Equipment main grid

(Side info bar)

Equipment Details Page

(Hierarchy section)

To create a Circuit:

  • Click the Plus to create a new Circuit.

  • Enter the required data in the pop-up window. See the table below.

  • Click Save when done.

The new Circuit will be created, and you will be redirected to the Details Page of the Circuit that was just created.

After the new Circuit has been added, IMS will automatically create:

  • A Corrosion Schedule (status ADMIN FINAL APPROVED). Each active Circuit should have one active Corrosion Schedule that acts as a “safety net” for which the minimal time interval is set (12 months); and

  • An Event History record for this new Circuit (Crct Added).

Circuit pop-up fields:

Field

Description

Equipment ID

This field is auto populated based on the object from which you are creating the Circuit.

Hierarchy

Hierarchy path for this Circuit (read-only).

Circuit

It is advised to use the MiRO naming convention when defining the Circuit ID.

Active

Indicator whether the Circuit is active or inactive.

Inspection Reason

Inspection Reason of the Circuit. When the inherit is active the Inspection Reason is inherited from the FLOC. The Inspection Reason determines the Time-Based Interval. You can select the default defined for the Circuit.

IDAP Status

NA

IDAP Status Comment

NA

Longitude / Latitude / Altitude

Geographic location based on coordinates on a map.

Suggested Corrosion Rate

Select the default. This is a mandatory field. However, this is only used in the standard IMS Corrosion Calculations and will not influence the M-IDAP calculations.

IF Strategy

Interval Factor (IF) Strategy, either IMS or SRBI. If SRBI is selected the SRBI calculated IF will be linked to the Circuit to be used in the Corrosion Schedule NID calculation. The linked Component should, in this case, be analyzed for at least one AR DM. When there is no SRBI IF the Circuit will default to the IMS IF. This is a mandatory field, but does not influence the M-IDAP calculations.

Interval Factor

IMS Interval Factor, default can be used based on Equipment Group. This is a mandatory field, but is not used in the M-IDAP calculations.

RBI Interval Factor

When Circuit inherits from Component, (worst) RBI Interval Factor from linked Component is being used. (read-only)

RBI Inspection Strategy

The RBI Inspection Strategy (IS) is shown if applicable. (read-only)

Inherit Components

If the related Component(s) are already created, you can select the inherit Components now. You can also set the inheritance at a later stage or on the Component Details page. This links the Component IF to the Circuit and the Circuit specs (also CR and RCA) to the Components. Also, the CL to which the Component is linked, will be linked to the Circuit. See Relationship between CLs, Components and Circuits.

Corrosion Loop

If Corrosion Loop is empty, the Equipment is not assigned to a Corrosion Loop.

CL Component

The Corrosion Loop of the inherited Component (read only), only populated when Circuit is inherited with a Component. See Relationship between CLs, Components and Circuits.

Required Inspection Method

You can set a required Inspection Method (e.g. UT, RT, UT-R) for all measurement for the Circuit (optional). This is not mandatory and can also be set on the MSET itself.

Description

Short description for the Circuit.

Special Emphasis

In case of Pipe and Pipe System Equipment, the Special Emphasis can be populated (when there is no pending event). The classification chosen determines the Maximum Inspection Interval (MII) allowed for the Calculation Summary and Corrosion Schedule.

Enable EVA

For Equipment of type bundles, you can enable Extreme Value Analysis (EVA) calculations. In this case an additional field will appear to enter the Number of tubes.

Calculation Method

NA for M-IDAP calculations.

Ignore Calculation Interval

NA for M-IDAP calculations.

Enable MIDAP

Make sure this is checked to enable the M-IDAP corrosion calculations.
