Damping Identification from Subsea Logger Axial Riser Response Data

ABSTRACT: For decades, it has been known that, as drilling riser deployment depths increase, the potential for excessive hook load response will also increase. Using data collected from a drilling riser deployed to a record-setting water depth, nearly 12,000 ft, this paper...
