| Description |
This study was a
Joint Industry Project (JIP) and is an adjunct investigation to Project
No. 147. The objective was to examine the important combined motion and
damping problems involved in the hydrodynamic analysis of deep-water risers and compliant
structures. The specific aims were:
(1) to improve present practice through the use of an
alternative to the Morison equation called the Inertial Pressure Method (IPM); and
(2) to explore improvements to the Morison methodology by
analyzing the IPM damping force time series for each test.
The time series data was partitioned into low frequency
patterns, indicative of patterns previously observed with simple periodic motion and the
IPM, and high frequency time series indicative of the damping forces. During the
performance period, the contractor explored improvements of the Morison methodology which
are indicated by these damping force coefficient |
| Progress |
Completed. A proposed continuation
of the project will not be funded. |
