A method for retrofitting existing drilling rigs with a catch pan. Firstly, provide a pan-like body consisting of two portions. Each portion includes an interior edge having a semi-circular indentation with depending semi-cylindrical collar. Latches are provided to secure the interior edges in abutting relation with the semi-cylindrical collars mating to form a cylindrical collar. Secondly, secure the body to a flow nipple disposed below an opening in a drilling platform by positioning the semi-circular indentations with depending semi-cylindrical collars one opposed sides of the flow nipple, and using the latches means to secure the interior edges in abutting relation. Drilling fluids from the drilling platform are caught in the pan-like body and directed into the flow nipple.
