Microprocessor Control System, Model 1200A with gyro input . . holds vessel's heading. System also accepts compatible NAV, AIDS fore-alt and slow speed propulsion and positioning. MODULAR THRUSTER SYSTEM.. OMNITHRUSTER ship control systems* utilize individual module thrusters of up to 1000 HP in any combination to produce desired forward or lateral net thrust. Prime movers for the Modular Thruster System may be electric, hydraulic or diesel powered in conjunction with manual/automatic or integrated control networks.

It is approximately three highway miles southeast of the Julien Du- buque Bridge linking Iowa and Illinois. New MarAd Reports On Ship Structure Collapse The Maritime Administration has released two related reports, "Formulas and Procedures for Estimating the Collapse Loads of Ship Structural Members," and "Structural Analysis of the Col- lapsing Row of A Striking Ship." Both reports were prepared for MarAd by Hydronautics, Inc. The reports are available from the National Technical Informa- tion Service, 5285 Port Roval Road, Springfield, Va. 22161. Their respective order numbers and prices are PB81-221855, $8; and PB81-111838, $12.50. SHIPBUILDING AND DOCKING CO. Head Office: PRAT 856, Plso 14, Valparaiso, Chile.
