Abstract
The global nonlinear dynamics of a typical mobile offshore drilling unit (MODU) about its critical, approximately quartering axis is described. It is well known that short and wide twin hull vessels such as MODUs have minimum righting moment about an approximately quartering axis. The effect of the out-of-plane coupling is investigated using advanced decoupling techniques known as nonlinear normal modes. These techniques are applied to the capsized MODU Ocean Ranger as an example.
