| Summary: | The extreme towline tension prediction methods used by the U.S. Navy are based on analytical models developed by Milgram, Triantafyllou, Frimm and
Anagnostou (1988) . The analysis of the test results for an instrumented offshore tow
conducted in 1989 indicated that the analytical model underpredicted extreme tension.
The reason for the underprediction of the extreme tension was the analytical model
did not account for the second order ship surge motions and resulting low frequency
tension fluctuations. Frimm and Milgram (1991) proposed a semi-empirical correction to the extreme tension model based on an analysis of the at sea test results... |
