Purpose:

Suppose a situation where a big panel (for example, a complete deck) has been generated in the early design phase. Further suppose that this big panel has been broken down into panels of production (for example, block) size. In the detail design stage details are added and changes are made (for example, of dimensions and qualities), also in parts that have been derived form the original big panel. To make certain that these changes do not jeopardize the strength calculations made during the basic design stage, a function has been developed to assist the designer in comparing the original big panel with the derived panels of production size.

This function compares a number of component types (plates, stiffeners, welded flanges, pillars and brackets) regarding dimensions and quality. Found differences will be displayed both graphically and in a list. To identify a difference, AVEVA Marine must be able to find a component in the big panel in the same location as a component of the same type in the part panel. Additional requirements for stiffeners are that they have to be on the same side of the panel and have the same inclination.

In the view of the part panel the following colours are used to indicate differences/no differences compared to the big panel:

• The dimensions are smaller or the quality differs: Red

• The dimensions are bigger and the quality is the same: Blue

• The dimensions and quality are the same: Green

• No corresponding component found on the big panel: White

For the big panel:

• No corresponding component found on the part panel: White

The identity of the component will also be displayed to make it easier to find the corresponding row in the list of differences that is also displayed. This difference list contains the component identity, the dimensions and quality of matching components of both the part panel and big panel.

Prerequisites:

None

Instructions:

Select the big panel and the part panel to be compared.

Options:

Using the Option button will give the user a possibility to key in the name of the big panel or the part panel instead of indicating

Result:

The differences are displayed in the drawing (using colours as described above) and in a dialog window on the screen. The differences optionally be output as a CSV list.
