The engine room is the heart of a ship. It is where the power is generated to drive the ship, and is also where power is provided for the ship's generators. The generators provide electricity for the ship's lights and the D.C. motors which operate the fire and bilge pumps and many other vital ship's motors.

Additional stairways have been added to the engine room so tours can be conducted while the ship is under way. The ship is open to the public seven [7] days a week from 9:00a.m. to 4:30 p.m. There are crew members aboard who will be happy to explain all functions of the ship to you.

The main power is derived from two [2] Babcock & Wilcox Boilers. These are forced draught, water-tube type boilers with superheaters and economizers. They perform at a pressure of 450 p.s.i. at 750 degrees Fahrenheit, and they each have 6000 sq. ft. of heating surface, plus an additional 2400 sq.ft. provided by the superheaters and economizers.

The power derived from the boilers is used to run the main turbines. The turbines are cross-compound driven, double reduction gears which drive a 16" by 166' shaft.

Their are two [2] refrigerator compressors to maintain the temperature in the walk in freezer & chill boxes. There are also two [2] air compressors of 125 p.s.i. each with 200 gallon receivers.

This panel shows the following:

• steam pressure of each boiler [400 lb]
• the superheat temperature of 750 degrees Fahrenheit
• fuel oil temperature
• combustion air pressure
• various control air pressure gauges for the automatic water controls of each boiler.

This panel has gauges for the following:

• main steam pressure
• vacuum pressure
• auxillary steam pressure
• level of the D.C. heater
• level of the main gear sump
• r.p.m.s of the shaft
• total revolutions of the shaft
• control air pressure, and
• the forward & astern main throttle wheels.

Many other gauges and operating conditions can be seen from this important station while under way on our summer cruises.

The fuel oil service system provides fuel oil at the desired pressure, purity and temperature conditions. The oil is delivered to the burners of the boilers from the fuel oil settling tanks, or in a emergency from the inner bottom tanks. This system is arranged so that diesel oil may be delivered to the burners for cold ship starting. The fireman on duty will be glad to explain this important part of steaming for you when you visit the ship.

The power from the main turbine is transmitted to the propellor through the propellor shaft, which is 16" in diameter and 166' long. The shaft rests on numerous carrier bearings and and runs through the stern of the ship by means of a bearing made of of lingnum vitae to a 18' 6" propellor. The shaft is made of solid steel, and at full power it transmits 6000 hp. at approximately 90 r.p.m. to the propellor.
