Method and apparatus for operating hydraulic equipment through a rotary table

An apparatus for providing hydraulic power below a snubbing unit, comprising:

• a swivel assembly having at least one hydraulic port therein, the swivel assembly defining a first hydraulic channel connected to the at least one hydraulic port, wherein the swivel assembly further comprises:
• a swivel housing defining an opening therein and having a lower swivel housing flange;
• a swivel including a first portion that inserts into the swivel housing and a swivel flange that connects to a top edge of the first portion;
• wherein the at least one hydraulic port is located on the swivel flange;
• wherein the swivel flange defines a first portion of the first hydraulic channel;
• and
• wherein the first portion of the swivel defines a second portion of the first hydraulic channel that runs a length of the first portion of the swivel;
• a rotary table;
• a rotary mounted within the rotary table having a second hydraulic port therein below the rotary table, the rotary defining a second hydraulic channel therein connected to the second hydraulic port, wherein the rotary further comprises:
• a first cylinder portion that connects to the lower swivel housing flange;
• a lower rotary flange that connects to a bottom edge of the first cylinder portion of the rotary;
• wherein the second hydraulic port is located on the lower rotary flange;
• wherein the lower rotary flange defines a first portion of the second hydraulic channel;
• and
• wherein the first cylinder portion of the rotary defines a second portion of the second hydraulic channel that runs a length of the first cylinder portion of the rotary and interfaces with the second portion of the first hydraulic channel;
• wherein the rotary is connected to the swivel assembly such that the first hydraulic channel aligns with the second hydraulic channel to provide for hydraulic fluid flow therebetween;
• and
• wherein hydraulic fluid is provided from the at least one hydraulic port through the first hydraulic channel of the swivel assembly and the second hydraulic channel of the rotary to the second hydraulic port below the rotary table.

A method for providing hydraulic power below a snubbing unit, comprising:

• defining a first hydraulic channel connected to at least one hydraulic port in a swivel assembly;
• defining a second hydraulic channel within a rotary mounted within a rotary table connected to a second hydraulic port located below the rotary table;
• connecting the rotary to the swivel assembly such that the first hydraulic channel aligns with the second hydraulic channel to provide for hydraulic fluid flow therebetween;
• providing hydraulic fluid from the at least one hydraulic port through the first hydraulic channel of the swivel assembly and the second hydraulic channel of the rotary to the second hydraulic port below the rotary table;
• connecting a hydraulically powered mechanism below the rotary table;
• and
• receiving the hydraulic fluid to power the hydraulically powered mechanism from the second hydraulic port below the rotary table.
