Black Consulting specialzes in offshore platform structural vibration data collection and analysis.
The purpose is to use low cost topsides acceleration measurments to assess a platform's structural conditon.
An offshore platform responds to ambient environmental forces (waves and winds) in a dynamic manner with a peak response at the platform’s resonant (natural) frequency. The resonant frequency will shift if the platform’s stiffness or mass changes. This principle is used to determine if a frequency shift indicates a loss of platform stiffness. This is a low cost method of assessing structural integrity since all work is done topsides.
