This book describes new methods developed for modelling dynamics of
machines commonly used in the offshore industry. These methods are
based both on the rigid finite element method, used for the
description of link deformations, and on homogeneous
transformations and joint coordinates, which is applied to the
modelling of multibody system dynamics. In this monograph, the
bases of the rigid finite element method and homogeneous
transformations are introduced. Selected models for modelling
dynamics of offshore devices are then verified both by using
commercial software, based on the finite element method, as well as
by using additional methods. Examples of mathematical models of
offshore machines, such as a gantry crane for Blowout-Preventer
(BOP) valve block transportation, a pedestal crane with shock
absorber, and pipe laying machinery are presented. Selected
problems of control in offshore machinery as well as dynamic
optimization in device control are also discussed. Additionally,
numerical simulations of pipe-laying operations taking active reel
drive into account are shown.
