Hitachi To Build Third Jackup Rig For Danish J.L Offshore Drilling Hitachi Zosen recently received an order for construction of an- other cantilever type, jackup off- shore oil drilling rig for J.L. Off- shore Drilling A/S, Copenhagen. This is the third rig of this type to be ordered from Hitachi by J.L. Offshore. All three rigs are designed for operation under rough sea and severe weather conditions. The first is scheduled for delivery on July 1, 1981, the second on October 1, 1981, and this latest one in January 1982. The rig is designed for oper- ation in water depths under se- vere North Sea weather condi- tions of up to 62.5 meters (205 feet) and in water depths of less severe weather conditions of up to 91.8 meters (301 feet). It ranks among the world's largest of this kind, a cantilever type. Hitachi has drawn upon its long and ex- tensive experience in both marine and industrial fields in the design and construction of this highly advanced rig. Hull dimensions are 70 by 76 by 7 meters. The three legs have an overall length of 104.8 meters (343 feet), and can be extended up to 129.5 meters (425 feet). The rig will be built at Hitachi's Ariake Works to American Bu- reau of Shipping Classification. It will have a complement of 72 per- sons, and drilling capability of 6,096 meters (20,000 feet). J.E.

New Brochure Available From Unimation On Portable Welding Robot A new, illustrated brochure cov- ering the benefits and capabilities of the Unimate® Apprentice® arc welding robot is available from Unimation Inc., Danbury, Conn. The brochure references the ro- bot as an economical automatic welder that provides greater arc time and better weld quality. De- signed for one-of-a-kind weld- ments, as well as repetitive weld- ing, the Apprentice robot can be programmed in minutes. It easily compensates for poor metal fit ups, and eliminates most of the OSHA-mandated protection de- vices required by welder opera- tors. Covered in the new brochure are the robot's ease-of-use, and ver- satility. Specification diagrams, mounting configurations and ex- amples of Apprentice robots cur- rently in use in industry are in- cluded in the 8V2 x 11 brochure.

As a professional, you know that speed, efficiency and maneuverability are increasingly important to your profitability. That's why — when it comes to making the right move — you should run with Michigan-Jastram Bow Thrusters, Michigan-Jastram combines Michigan Wheel's experience in design and manufacturing of propellers and nozzle systems with the ex perience in design and manufacturing of right angle gears and thrusters of Jastram-Werke of Hamburg, Germany, The result...the latest designs of propulsion and maneuvering equipment in North America today. Michigan-Jastram Bow Thrusters are your modern means of improving maneuvering capabilities in ships of all sizes and types. By generating transverse thrust, the vessel achieves the ultimate manageability. Especially at slow speed, when the main rudder ceases to respond, the ship can still maintain control. What that means for you is improved maneuvering capability, substantial saving of tugboat charges, reduced risk of collision and increased safety at low visibility, Michigan-Jastram Bow Thrusters are usually delivered with full length high quality tunnels for lower material cost and ease of installation. Once installed in the vessel hull, simply connect the system to your engine. In its standard form the bow thruster gear and propeller can be removed through the tunnel. Michigan-Jastram, a part of Michigan's new Michigan Propulsion Systems Group, is playing a major role in the development of Michigan- maneuvering techniques. 1 i^B f laslram . . , c ^ , I —.
