... testing, it has been possible to compare the Axial Excitation Tool performance at drill string fish resonance frequency with other frequencies. The rig tests demonstrate significant increase in fish response amplitude with the Axial Excitation Tool present at the resonance frequency. Full scale field...

..., is mainly low frequency persistent excitation. This is partially due to the low frequency nature of ocean swells as well as to the sharp response of the drillship around the resonant frequency of the coupled drillship-ocean vibration system. Observed drillship oscillation periods are typically above 7...
