Ship, Tow-Tether and Moonpool Models

The file “Ship, Tow-Tether and Moonpool Models.zip” is a collection of linked macro-enabled Excel workbooks suitable for conceptual to preliminary design of the title systems. The file “Block Diagram.pdf” shows linkages and summarizes each workbooks’ major features. FD and TD at the end of a file name denotes frequency domain and time domain solutions, respectively. Except for the moonpool TD model, which is a solution to the nonlinear equations of motion for the moonpool piston mode, TD solutions are obtained by superposing FD solutions in uniform random phase.

Toolbars on the plot tabs can be activated to expose plot options. Model input parameters are defined in comments to the input cells of each workbook. (Use the TAB key to move between input cell.) Dropdown menus on the first worksheet of each linked workbooks facilitate moving between open workbooks.

Supporting documentation is included.
