QUICKWAVE AND DESIGNER WAVE: UTILIZING APPROXIMATE METHODS FOR RIGOROUS PRELIMINARY DESIGN METHODS FOR COMPLIANT TOWERS

This paper describes the use of approximate (simple) and rigorous methods appropriate for the preliminary design of compliant towers. The novel design tools described include the "Designer Wave" and the "Quickwave". The design of deepwater bottom- founded towers (300 to 1,000m) requires a good understanding of the nature of the design environment, the structural response, design force levels and practical member sizing. The "Designer Wave" is a practical short portion of random wave simulation, derived from rigorous analysis, that captures enough of the important features of structural response for design purposes. The "Quickwave" method achieves reasonably accurate design forces and member sizes without using time consuming random wave runs and full 3-D structural models. The Designer Wave is essential for the occasional calibration of the Quickwave results. Many design iterations are relatively easy with the Quickwave, so much so that it was extensively used to derive a new deepwater compliant tower concept.
