Inthis dissertation, the relationship between the bandwidth, the arrayschemeandfeedingwaveguide is studied. As a solution, choke grooves are used to expandthebandwidth.
And because of the increased containment capacity out of the sealing cap, the choke line, which was feeding to the Q4000 at about 10, 000 barrels a day, will have its containment capability increased to 20, 000 to 25, 000 barrels a day.
