... Abstract We present a semi-analytical method to analyze the multi-string mechanical response of the tubulars, the wellhead and the mudline hangers (MLH) in offshore wells with a mudline suspension system (MLS). The MLS introduces redundancies at the MLH shoulders. In our method, the tubulars...
