A Lagally formulation of the second-order slowly-varying drift forces

Abstract

A new formulation of the second-order difference frequency loads is proposed, based on the Lagally theorem. With this formulation, the quadratic part of the QTFs is expressed as the sum of two integrals over the body surface plus one integral over the interior free surface. The good convergence properties of this new formulation are illustrated over three test cases: a vertical cylinder standing on the sea-floor, a floating hemisphere and a FPSO.
