Seakeeping Strip Theory
Seakeeping strip theory is a method for predicting the dynamic motion of a ship in regular and irregular waves by decomposing the hull into two-dimensional transverse sections (strips) and computing the hydrodynamic forces on each strip. Developed by Salvesen, Tuck, and Faltinsen in 1970, the method efficiently estimates ship heave, pitch, and roll motions, accelerations, and loads without resorting to expensive three-dimensional computational fluid dynamics. Seakeeping analysis using strip theory is standard in ship design and operational planning.
