OMNITHRUSTER® Thrust Is Forwards And Sideways And Backwards 360° Maneuvering, Slow-Speed Propulsion, Ice Management! Thrusts Underway Thrusts While Pitching No Reversing Impeller to Change Directions Minimum Buoyancy Loss Smaller Hull Penetration Fuel Savings OMNITHRUSTER DOES IT ALL! Thrusts with nozzles out of water in rough seas: vertical systems only. No protrusions ... no change in hull shape. Small nozzles reduce drag . . . save fuel and passage time. \ Easily retrofitted. Micro-Processor Control System, Model 1200A . . with gyro input . . . holds vessel's heading. System also accepts compatible NAV/A1DS fore aft and slow speed propulsion and positioning. MODULAR THRUSTER SYSTEM . .. OMNTTHRUSTER ship control systems* utilize individual module thrusters of up to 3000 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. ADVANTAGES FOR LARGE VESSELS . . . • Incremental Thrust Capability • Multiple Module Reliability • Easily Retrofitted or Installed in New Construction • Minimum Maintenance JT/PVl 100-1000HP MODULE THRUSTER •Covered by U.

R J Brown Initiates Pipeline Study For Alaskan Diapir Area R J Brown and Associates, Houston, has initiated a joint in- dustry study on the feasibility and costs of offshore pipeline transpor- tation in the Diapir area, off Alaska. This area is subject of planned OCS Lease Sale 87, scheduled for mid-1984. A significant portion of this area is permanently covered by the Po- lar ice pack. Novel pipeline con- struction techniques need to be in- vestigated and developed in order that submarine pipelines can be economically installed in such an environment. Subjects to be addressed include establishing a data base, design criteria, review and selection of pipeline installation and trench- ing methods, and cost estimates. Companies interested in joining the study as a late participant should contact Jim Gillespie at the RJBA Houston office, tele- phone (713) 683-9333, telex 762186 or 4620114.
