Used in conjunction with standard abrasive blast machines, pipe cleaning tools simply re- place conventional blast nozzles at the end of the hose. The Spin-Blast Tool incorporates a rotating head with two nozzles to propel abra- sive to the surface. 'The Hollo-Blast Tool utilizes a deflection tip to direct abrasive to the surface, and the Hollo-Blast Junior utilizes a deflection tip like the Hollo-Blast, but with smaller pro- portions to accommodate pipe with inner diame- ters of %-inch to 2 inches. Through this highly powered abrasive impact, precise surface pro- files can be obtained, which will ensure proper adhesion for long life coatings. Various Tungsten Carbide nozzle sizes are available to comply with the range of pipe diam- eters. Internal pipe surface preparation is said to be easier, faster and more economical with the Clemco Internal Pipe Cleaning Tools.

Immediately following de- livery, the rig left under tow for India, where it will begin drilling offshore Bombay. The new unit is the 21st jackup drilling rig built by Hitachi Zosen, and the third built for ONGC. The company's rig backlog includes four more jackups, five semisubmersibles, and one drillship. Designed and built to American Bureau of Shipping class, the Sugar Ratna's platform is 216.5 feet long, 200 feet wide, and 23 feet deep, with a draft of 13.6 feet. The rig's three legs are 420 feet long, permitting drilling in water depths up to 300 feet, to a well depth of 20,000 feet. It is designed to withstand winds of about 120 mph and waves more than 60 feet high. As the spud tank can be completely retracted inside the platform, there are no protrusions from the platform bottom, making it easy and safe to tow the rig in shallow waters or to trans- port it on a barge or heavy-lift ship. An on-board computer will facilitate efficient rig operation by performing stability and leg load calculations, as well as aiding with drilling, spares management, and equipment maintenance.
