Dynamic response and runup on spar platforms Conference Paper

abstract

• Deep draft spar platforms are an attractive concept for the recovery of oil at deepwater sites. This study reports on a series of large scale model tests in which the dynamic response of a large moored spar and a smaller tethered spar platform design were investigated. To put these spar platform designs in perspective with those already designed and built, some geometric and dynamic characteristics of all the designs are compared and discussed. The model spars were subjected to both operational and one-hundred year design seas. Their response behavior is characterized using statistical parameters, probability plots and linear spectral analyses. The heave and pitch response was shown to be well approximated as a narrow-band Gaussian processes. Spectral analysis of single point measurement of the wave runup data revealed a modest degree of amplification of the incident waves. This amplification does not fully account for the behavior observed in the model tests.
