DEEPWATER FLOATING DRILLING AND PRODUCTION FACILITY INCORPORATING FLEXIBLE PRODUCTION RISERS

摘要

ABSTRACT OF THE DISCLOSUREA method of using a floating platform in deep(1000-3000 feet) water as a drilling/workover and productionplatform. By interconnecting the subsea wellheads of atleast one template to the platform using flexible productionrisers connected through a reverse loop, the platform may beadjusted on its moorings to position the platform directlyover a second template for subsequent drilling or workover.This eliminates the additional expense of separate drillingplatforms and workboats. Further, wells of separatetemplates can be serviced separately and the entire fieldproduction need not be completely curtailed during such aworkover.
