Applications of Models of Offshore Structures

Abstract

Each offshore structure is unique in the sense that it is built only after a customer with a specific need actually places an order. Design companies and manufacturers of engineering systems of this type are often small and medium enterprises, which cannot afford purchasing costly computer software packages for numerical computation involved in dynamics of mechanical systems. Therefore, they often employ custom, in-house dynamic models of the structures designed. In the present chapter, dynamic models of the following are presented: a gantry suited for relocating sets of BOP valves on an extraction platform, a column crane and a device for laying pipes on the seabed. The formulation of models thereof leverages the methods described in earlier chapters.
