Hydrodynamic Properties of Complex Subsea Structures
This project is aimed at deriving the hydrodynamic properties of complex subsea structures, which are important during the structure’s installation, in mid-water and near the seabed. Presently, there are three methods used in estimating these coefficients, analytical, numerical and experimental. The numerical method using Computational Fluid Dynamics was chosen because of its advantages over other methods in terms of economics, time and its ability to handle several models simultaneoulsly. Figure 1 below shows an integrated structure used as a protective cover for subsea production equipment.
Of interest, is the heave added mass, damping and linear drag coefficients which have a great influence on the dynamic performance of this type of structure during installation in both shallow and deepwater environments. Installation time and cost can be reduced and personnel confidence/safety increased if these properties are accurately determined.
