Seakeeping model tests of a 400 MW OTEC spar platform and cold water pipe

PDF Version Also Available for Download.

Description

A number of theoretical methods are currently being used to predict seakeeping behavior (behavior in a seaway) of complete OTEC plants including a platform and CWP. Validation of these methods is generally limited, due in part to the limited available test data. To date no at-sea data and only one set of model test data are available for a complete OTEC plant. The primary purpose of the present and previous tests is to provide data for validation. The present tests are for a large (400 MW) spar type platform developed by Lockheed Missiles and Space Company (LMSC). A 1:110 scale ... continued below

Description

A number of theoretical methods are currently being used to predict seakeeping behavior (behavior in a seaway) of complete OTEC plants including a platform and CWP. Validation of these methods is generally limited, due in part to the limited available test data. To date no at-sea data and only one set of model test data are available for a complete OTEC plant. The primary purpose of the present and previous tests is to provide data for validation. The present tests are for a large (400 MW) spar type platform developed by Lockheed Missiles and Space Company (LMSC). A 1:110 scale model was constructed and used for testing. Tests were carried out for the following configurations: spar alone, spar with CWP free in pitch and roll, and spar with CWP rigidly attached. For all seakeeping tests, wave height and five motions (heave, pitch, roll, surge, sway) of the spar model were measured. Results are presented in the form of response amplitude operators and significant (average of one-third highest) amplitudes for random waves. Test results are also compared with theoretical predictions made for the exact conditions of the test model. (WHK)
