Craneless elevatable MGS vessel and swivel joint U-tube mud line and method of installation

A craneless elevatable MGS vessel and U-tube assembly comprising:

• an MGS vessel mounted on a support base frame providing a swivel bed supporting the vessel providing a gas vent line extending from the distal end of the MGS vessel;
• and a U-joint connecting a sump line of the MGS vessel interposed between the sump line and a mud pit line providing a swivel joint at an upper end of the U-joint and a second swivel joint at a lower end of the U-joint, supported by a hydraulic cylinder connecting the upper extension of the U-joint to the adjacent extended U-joint member for moving the U-joint in an independent direction to align the U-joint with a mud handling system of a drilling rig;
• double-acting hydraulic lifting means for raising the vessel from its shipping position to its final operating position;
• and,
• a plurality of lifting lugs attached to MGS vessel in spaced relationship for attachment of the double-acting hydraulic lifting means at selectable positions along the MGS vessel permitting the operator to raise the MGS vessel to an appropriate height.
