In this paper the assessment of the hydrostatic collapse of submarine pipelines is addressed. Initially an overview of the classical approach is presented. Then a historical review of the classic methods is carried out. Seven assessment methods are reviewed: six well-known classic methods (the Southwell method, the Timoshenko method, the Shell method, the Murphey method, the Haagsma-Schaap method and the DNV method) and one newly developed classic method (the RCA method). Finally the collapse pressures previously calculated using Finite Element (FE) models are compared with those predicted by the seven methods.
