Most of the time the device, commonly called a B.O.P., does little but sit on the seabed as drilling pipe and liquids travel through its main bore, which is usually about a foot and a half wide.
For several thickness ratios and cross bore to main bore radius ratios, the variation of SCF with chamfer angle for various chamfer length (clr) ratios was investigated.
Where thickness ratio was between 1.25 and 2, a cross bore to main bore radius ratio of 0.075 was found to be a geometrical constant with a corresponding SCF of 2.65.
The main Bears highlight was Hester putting a nuclear-powered charge into the Bears with his return for a score on the opening kickoff.
