beyond anything www.kiswire.com Installation instructions Treatment of drill Lines shall be done as any other crane rope – with much care and knowhow. Here is a summary of issues : Order the right diameter of rope for the drill rig. Check grooves of drums and sheaves prior to installing the drill line. When spooling the drill line from factory reel to draw-works storage reel, make sure it is done according to the general rules for such spooling. For instance, over-wind to over-wind and under-wind to under-wind spooling. Commonly, the new drill line is spooled by connecting it to the old one. Be sure to make this connection strong enough, for instance by welded links. Any drill line shall be spooled and installed 100% rotation free. To guarantee a rotation free spooling it is recommended to unroll the drill line on a clean floor, make sure it is rotation free, and colour the rope with paint on the topside of the rope. When spooling the rope on the rig, one can now notice any possible twist occurring. Let this twist out before fixing the ends in the machine. The travelling block in the rig shall be aligned with the crown cluster block sheaves, as well as it shall be hung off, to prevent any movement of the travelling block. The drill line shall be spooled under tension. Special tensioning tools to perform this job are available. Give attention to the position of possible cylinders when installing the drill line. Wrong cylinder positions could upset the tensioning during reeving the rope. Slack of rope could be the result. Finally, when the drill line has been installed, the system shall be lifted and lowered under working tensions, several times, in order to let the rope bed in. Slip & Cut of Drill Lines The life of a drill line can be increased dramatically by using and following a planned cut-off program based on work performed. Such a plan moves the rope through the system so that the wear is spread uniformly along the entire length of the rope, enabling the line to be removed from the drawworks drum end when it has reached the end of its useful service life. As the rope is cut off the drawworks drum end, new rope is fed into the system from the storage drum on the dead line side. The art of slip and cut is to be prepared, have all the needed equipment ready and the number of rapes you intend to remove/slip worked out. Use the hang off line to hold the block and TDS weight before you remove the pigtail clamp on the dead man. When making a cut and slipping never be pulled through a loosened dead man clamp this could put a twist in the rope. The clamp should be completely removed and inspected. If worn or damaged, replace. Once ready, spool the amount of new line from the storage drum onto the drawworks drum, insure the line moves freely throughout the system, modern rigs have a rotating center drum on the dead man if yours doesn’t use a little oil to lubricate the wire so it slide freely around the dead man. Once you have transferred the amount of wire need across to the drawworks put the clamp back on the pigtail With the clamp holding on the dead man you can now start to remove the wire you intend to cut off, mark the number of reps you need to cut off, count from the drawworks clamp in, Using an air tugger with a sheave hoist the wire you intend to put back on the drum after the cut up the derrick, drive the wire from the drum, DRILL LINES for land - and offshore drill rigs.
