Lift-ready flowhead assembly

A method of suspending a flowhead assembly from a drilling rig including a hoisting assembly, the method comprising the steps of:

• (a) providing a lift-ready flowhead assembly comprising:
• (i) a flowhead assembly comprising:
• (1) a flowhead body including body threads and a side entry port;
• (2) a swivel housing;
• (3) a load collar tube rotatively supported in the swivel housing by a bearing assembly;
• and (4) a ball valve positioned in said flowhead body and configured to block and unblock a central passage running through the load collar tube and the flowhead body;
• and
• (ii) a lift sub including:
• (1) a head section;
• (2) a neck section having external neck threads, wherein the external neck threads engage the body threads of the flowhead body;
• (3) a sub passage extending through the head section and the neck section;
• and
• (iii) a lifting yoke disposed around the neck section of the lift sub and interposed in position by the head section of the lift sub and the flowhead body, the lifting yoke including:
• (1) a yoke body having a center aperture, wherein the yoke body is formed without a side gate;
• and (2) opposing pad-eyes extending from the yoke body;
• (b) connecting the hoisting assembly to the pad-eyes on the yoke body.

A method of assembling a lift-ready side-flow sub comprising the steps of:

• (a) providing a side-flow sub including a body including:
• (i) at least one pair of opposing side entry ports and
• (ii) a first threaded end;
• (b) connecting a lift sub to the first threaded end of the side-flow sub, the lift sub including:
• (i) a head section;
• (ii) a neck section having external neck threads, wherein the external neck threads engage the body threads of the flowhead body;
• (iii) a sub passage extending through the head section and the neck section;
• (c) positioning a lifting yoke around the neck section of the lift sub, wherein the lifting yoke is interposed in position by the head section of the lift sub and the flowhead body, the lifting yoke including:
• (i) a yoke body having a center aperture, wherein the yoke body is formed without a side gate;
• (ii) opposing pad-eyes extending from the yoke body.
