Dynamics of Offshore Structures – Basic Knowledge and Applications
This lecture has three main objectives:
(1) To discuss basic ideas, limitations and physical laws involved in modeling complex offshore structures as single freedom degree systems
(2) To quantify the important environmental forces, except for wave action, that occur offshore and show how these forces interact with structures and
(3) To illustrate the modeling of structural mass, stiffness and structural restraint forces of guy wires and soil foundations.
Emphasis will be given on the 1st step in dynamic engineering analysis, i.e on the formulation of the structural equations of motion, while wave actions as well as solutions for structural motions, both deterministic and stochastic, are considered known or at least easily approachable.
