In the DATE field below, indicate the month the report covers, not the month the report
is prepared. For example, if you are preparing a report for February 2009 on March 7,2009, you would select February 2009 below. Please submit your monthly report viaemail to the Project Manager with a copy to the Champion by the 7 th day of the monthfollowing the report. The report file name should be saved as:Month_CTR#_Company Name (i.e., Feb_9401c_AMOG Consulting).
9401c VIV Data Analysis, Methods and Guidelines (CTR 8402, Part 2)"Explore full-scale VIV riser data (available from BP) to draw somecomparisons/contrasts to the underlying physical behavior of the smaller scaleDeepStar data ('Miami2')
Data Segmentation and Synchronization: It is proposed to review the full scale
accelerometer data (consisting of BP's hung off drill pipe, disconnected andconnected drilling riser data) and sub-divide into 25 chunks then performdetailed investigation on each chunk. Each chunk will be chosen so that a widerange of different conditions are obtained in the final detailed analysis stage.Two (2) chunks will be chosen that cover suppression devices. Howeversynchronization is an important issue and a decision on the data subdivisionmay also occur based on finding characteristic unique 'alignment' points in thedata. Current velocity information will also be synchronized to theaccelerometers at this stage. The second phase (Section 3.2) 'data exploration'is contingent on the success of the first phase and is proposed to requireDeepStar approval prior to commencement.
Data Vector rotation: Where possible a determination of the principal cross-flow
and in-line directions of vibration in the 15 chunks of data will be made bymaximizing fundamental frequency peak in spectrum. Also crosschecking withany directional information available from current profile.
Prediction of structural response characteristics Using simple line dynamics
software (Orcaflex) structural response natural frequencies and wavepropagation parameters will be determined for use in drawing results in theexploration phase.
