Types of Tags

There are three different types of stiffener tags, two of which are set automatically. The third one is user defined.

1. Stiffeners that lie in planes, which are close to horizontal or vertical, and the end points of which are close to the longitudinal horizontal distance from the CL or to the longitudinal vertical distance from the BL are given a tag which is identical to the longitudinal number.

   The longitudinal positions used are the theoretical midship positions for longitudinals that are defined in the initialization of a new project. A longitudinal position can be defined, even if there is no physical longitudinal, for example, in the position of a girder or a stringer.

   Stiffeners located on the position of longitudinals on the starboard side are given the negative longitudinal number as the tag. The image below illustrates how the tags are set:

   

   Stiffeners	Longitudinal tag No.
   A	- 2
   a, B	- 1
   b, C	1
   c, E	3
   F	4
   G	none
   d, e	31
   f	none

2. Stiffeners located in or close to a frame plane and close to a frame coordinate will be given a tag, identical with the frame number.

3. Quite a number of stiffeners will not be given any tag automatically, because they do not follow the conditions above. Nevertheless, it may be desirable to be able to refer to them with stable references, for example, a stiffener on a platform which is not parallel to CL or stiffeners on a sloping hopper tank top.

   Then the user, in generating a stiffener, can assign a tag as an integer number in the interval 1-999, using the keyword TAG. Such a user defined tag always overrides an automatically selected tag.
