Abstract

DC60 (06/07/49) Rigid tubular construction for connecting drilling from the dredger to the pre-arranged levers. On the sea floor Which consists of a pipe set where The drilling path can be passed for oil well drilling as well as a long overhang of pressure hoses to control the action of the valves. And floating parts placed around the stand and pressure pipes to limit the load on the drilling rig. The riser and pressure hoses are assembled from a module that can be connected together. The floating components are constructed by a tightly sealed, leak-proof steel tube chamber positioned around the module. And tightly connected to the said module. In addition The invention also involved the upright module. Riser tubular structure for connecting drilling from the dredger to the pre-engineered tongues.
