A system and associated method for reducing pressure are provided. The system includes a pressure-reducing device having an inlet tubular member defining an inlet port and adapted to engage a pressurized chamber having a fluid therein, and an outlet tubular member having a distal end defining an outlet port being adapted to extend to a surface external to the pressurized chamber. The pressure-reducing device channels the fluid to the surface external to the pressurized chamber via the outlet port. The system also includes manipulation tools configured to adjust one or more channels defined by the outlet tubular member to regulate a pressure within the pressurized chamber, the length of the one or more channels being proportional to the flow resistance imparted to or the backpressure on a fluid flowing from the inlet port to the outlet port by at least the outlet tubular member.
