McMullen's Newport News

Office Installs Inter-

Active Graphics System

John J. McMullen Associates,

Inc. (JJMA), naval architects, marine engineers and transpor- tation consultants of New York, recently installed an AUTO-TROL

AD/380 Interactive Graphics Sys- tem in its detail design office lo- cated in Newport News, Va. This office, known as JJMA's Hampton

Roads Operation (HRO), has been fitted with four 25-inch screen terminals, a backlit digitizer ta- ble, a hard copy unit, a flatbed plotter, a message center, and an alpha-numeric programming ter- minal. This peripheral equipment is interfaced with a Sperry Uni- vac V77 Model 800 computer. File storage is obtained through the use of a CDC Eagle Disc Drive having a storage capacity of 80 megabytes.

A staff of HRO designers ex- perienced in the structural, elec- trical, piping, and HVAC design disciplines has been trained in op- eration of the system. HRO cur- rently has 135 designers and draftsmen employed, and is in- volved with the detail design for construction of several major shipbuilding projects.

Thomas R. Marr has been en- gaged as system manager for the interactive graphic system in- stallation at HRO. He comes to

HRO from Nuclear Power Serv- ices, Inc., where he was employed as system manager, Automated

Graphics Division.

John J. McMullen Associates has its principal office at Suite 3000, One World Trade Center,

New York, N.Y. 10048.

McDermott Orders Rig

Systems For Hutton Field

From Hydranautics

Hydranautics, Inc. has been chosen by McDermott Engineer- ing Ltd. of London to provide two complete hydraulic rig systems for use on Amoco's Northwest

Hutton Field platform in the

North Sea (U.K.).

The contract calls for eight 200-ton, push/pull piston gripper jacks, four 80-ton lift systems, two control panels, and power supplies. The Hydranautics equip- ment will be used for moving the drilling derrick from well to well and for lifting/lowering the blow- out preventors. The Hydranautics equipment has a maximum mov- ing capacity of 2,000 tons at 20 percent coefficient of friction.

The equipment is scheduled to be shipped in early 1981, and should be installed and operating on the platform in 1982. With the

McDermott order, Hydranautics will have supplied well over 200 rig-skidding systems to the off- shore oil industry for use on nearly every large, multi-well off- shore platform in the world.

McDermott Engineering, Ltd. is responsible for the management of the topside design of the

Amoco platform.

Goodyear Bralceability:

Disc brakes, more efficient, more effective than band brakes under dynamic operation.

As a leader in disc brake technology, we supply brakes for bow thrust engines, propeller shafts, anchor windlasses, winches, as well as other uses.

Disc brakes offer many advantages over band and shoe brakes. They are smaller. They can perform in both static and dynamic situations. Their non-self-energizing characteristic assures smooth, controlled payout and superior brake control. The large exposed disc surface dissipates more energy and heat.

Goodyear manufactured friction materials exhibit minimum fade at elevated temperatures and high energy input rates. As the linings wear, pistons continually advance, keeping displacement constant for each application. Quick-change lining design allows minimum downtime for replacement.

Our disc brakes are available in a complete line of caliper designs from 2xh lb. to 300 lb. units. By varying caliper multiples, disc thicknesses, operating pressures, etc., one brake caliper can be used across a complete product line.

Marketing Manager, Industrial Brakes, Goodyear

Aerospace Corporation, Box 427, Berea, Kentucky 40403, (606) 986-9381.

We know how to make things work.
