Introduction LSS-Steam LSS-Diesel LSS-G

LSS-Steam

Available in either LSS (full mission) or LSS-G (PC-based) formats, our Steam Propulsion Trainer was developed in conjunction with the California Maritime Academy, Vallejo U.S.A. It simulates an entire Steam Plant including the following systems:

Electrical Power Plant comprising 1 Diesel Alternator, 2 Turbo Alternators, I Emergency Alternator, Synchronizing Section Earth Leakage, Circuit Breakers with overload trip protection. Alternator Auxiliary systems - Cooling, Lubrication, Fuel and Air, Alternator Controls include: Manual and Auto Start and Synchronization, Governor Speed Control with adjustable droop, Manual or Automatic Voltage Control. Real Time color graphic display of kW, kVAr, I,V,PF including vector diagram format.

Boilers - Two D-Type boilers with separate controls generate Superheated and De-superheated steam using an attemperator.

Cooling System - comprising Sea Water Cooling using a Scoop or main Circulation.

Fuel System - Heavy and Diesel Oil Bunker and Service Systems, Full Burner management Module with integral Alarms, purge sequence and trips. Steam Heating of Heavy Oil including re-circulation

Lubrication System - The main lubrication system comprises a gravity fed storage tank, hydraulic throttle pump, HP, LP and Shaft bearing lubrication.

Compressed Air System - Generated by separate control and service air compressors, the air system includes 20psi lines for steam regulators and 70psi for boiler controls.

PID Control Systems comprise cascaded Plant Master, Master, Fuel, Air, fuel-Air Ratio with Hi-Lo selection. All controllers can be individually programmed for Set Point, Proportional Band, Integral and Derivative Time and can be set for manual or automatic operation. Other PID controllers include Drum Water Level, Feed Pump Differential Pressure and Superheated Steam Temperature.

Main Turbines - include 2-stage HP and 2-stage LP plus an astern turbine. Each has independent Lubrication and Gland Steam. A dynamic Mollier diagram and Entropy / Enthalpy Diagrams are available for advanced teaching.

Condensate System - Main Condenser (Vacuum assisted with air-ejectors), Condensate (with 2 pumps), Atmospheric Drain Tank, De-aerator (DFT) and DFT Dump System.

Feed Water System - includes two steam-driven Feed Pumps and one electric feed pump. HP and IP bled steam and 875 to 150 psi regulator.

Other Systems - Bilge, Fire, Fresh Water Generator, Vibration and Salinity Monitoring, Alarm System, Telegraph and Throttle, Turbine speed reductions and trips

Instructor Facilities - The instructor may change critical values such as Ambient & Sea Temperatures, Fuel Quality and Fuel Analysis, Cargo Pump Loading. Alternator Droop etc.

Faults - Over 400 faults available to the instructor

The full mission system comprises:

• Main Engine Control Desk
  
• Main Electrical Switchboard
  
• Emergency Switchboard
  
• Generator Local Control Panel
  
• Instructor Desk
  
• Student PCs for Control and Monitoring
