A string of pipe formed by the connection together of multiple joints of shorter pipe segments is stored in the water space adjacent an offshore drilling rig. The pipe string bends from the drilling rig floor in a semicircular arc and enters the water adjacent the drilling rig. A curving guide is used to direct the pipe string movement. A platform extension from the corner of the drilling rig is provided to position a work area above the point at which the pipe enters the water. Multiple guides may be employed for simultaneously running two strings of pipe. The string may be stored in one or more long sections or in a single continuous string. The major portions of the string or long pipe sections may be stored below the surface of the water. Provision is made for pumping fluids through the pipe string, and/or the pipe sections, to the well. The string may be stored in a sleeve.

A power tong system is used to make up and break out threaded pipe connections. Rotary power tongs are connected to an integral backup tong through an extendable hydraulic cylinder and rod. A brake is secured to the rotary tong to selectively hold the pipe stationary relative to the rotary tong. When rotation of the pipe by the rotary tong ceases, the brake is applied, and the cylinder and rod are actuated to angularly displace the power tongs and the backup tong to apply a torque force to the pipe connection disposed between the power tongs and the backup. A resulting torque force is obtained that is greater than the maximum torque that can be exerted by the rotary tong acting alone. The system may also be deployed to apply and hold precise torque forces on the pipe connections. When used to obtain a makeup torque below the maximum rated rotary tong output, the rotary tong is regulated to limit its torque output. When the limited torque is reached, the brake is applied and the cylinder and rod are actuated to apply a smooth, closely controlled increase in torque to the connection.

A sheet of paper is provided with pressure-sensitive adhesive on areas of its front and rear surfaces. In a preferred form, the sheet is provided as a pad of similar sheets that may be removed from the pad one sheet at a time. The adhesive on the rear of the sheet is employed to secure the sheet to a first object. The adhesive on the front of the sheet is employed to secure a second object to the sheet. An area of the sheet face free of adhesive may be employed for a written message. A modified sheet is provided with cuts formed in an adhesive area of the sheet so that the cut area of the paper may move away from the plane of the sheet to adhere to irregular surfaces. The cut sheet may have adhesive on one or both sides. Where the adhesive is applied to both sheet sides, pressure-sensitive adhesive on the back of the uncut side of the sheet is used for adhering the sheet to a smooth surface. One modification of the pad configuration provides individual sheets folded so that the adhesive on the sheet is covered by an adhesive-free portion of the sheet so that no adhesive is exposed on the top of the pad.

Control lines extend vertically through lateral spaces formed between a rig floor and a pipe holding assembly supported on the rig floor. A pipe string held by an elevator extends vertically through the pipe holding assembly into the well. The pipe holding assembly is raised vertically off of the floor, about the pipe string, to allow the control lines to be clamped to the pipe string below the pipe holding assembly. The invention permits the control lines to be clamped to the pipe string without passing through the pipe handling assembly to prevent damage to the control lines when the pipe handling assembly is closed to secure the pipe string.
