An apparatus for improving thermal-mechanical stress resistance in a delayed coking drum having a drum shell. The apparatus includes a support skirt section configured to mount to and to assist in supporting the coking drum above a ground surface. A joining edge joins the support skirt section to an exterior portion of the drum shell. A T-shaped slot is formed in the support skirt section and is located proximate the joining edge. The T-shaped slot may be formed by a vertical slot portion and a horizontal slot portion joined together as a single slot.
