Forward Engine Room B-1


B-1 is the forward engine room.

The forward engine room contains the two main propulsion diesel engines on the port side, the number one ship's service generator on the starboard side, the forward electrical distribution panel and ancillary pumps and compressors needed to support the main propulsion equipment. The propulsion plant of the Evarts and Cannon class destroyer escorts essentially duplicated the propulsion machinery found in WWII US submarines. The primary difference being that there were no batteries.

As initially conceived, all destroyer escorts were to have steam turbine machinery similar to destroyers. However, a limitation in the ability to produce reduction gears in the needed quantities caused other sources of propulsion to be sought. Thus, many destroyer escorts, such as the SLATER, were built with diesel propulsion. While the diesel machinery did not produce the high horse power and speed of the steam machinery, it did provide for longer range and economical operation.

The space consists of upper and lower operating levels. The lower level contains two GM diesel engines (numbers one and two) for main propulsion, located on the port side. These are 16 cylinder Model 278s and each drove a separate direct current generator located in the next compartment aft, B-2. (Engine, Diesel, Main Propulsion, General Motors Co., Model 16-278A, 1700 HP, 750 RPM, 16 cylinder, 2 cycle.) This propulsion equipment is duplicated in space B-3. The duplication of machinery was a standard feature of US World War II destroyer design and it enabled ships to withstand incredible battle damage and still survive.

Also in this room is the diesel powered ship's service electrical generator. (Generator, Ships Service, Westinghouse Electric Co., SN 127619P525, 200 KW, 250 KVA, 321 Amps, 450 VAC, 60 Cycle, 3 Phase. Diesel Data: General Motors Corp., Cleveland Diesel Engine Division, Model 8-268A, SN 12574 11/17/45, 8 Cylinder, 2 Cycle, 350 HP, 1200 RPM.) Also located here are 2 lube oil service pumps (Pump, Lube Oil Service, Gear Type. Motor Data: Howell Electric Co., 3/4 HP, 1160 RPM, 440 VAC), 2 salt water circulating pumps (Pump, Salt Water Circulating, DeLaval Co., Centrifugal. Motor Data: Allis-Chalmers Co., 7 1/2 HP, 1740 RPM, 440 VAC.), and a fire and bilge pump (Pump, Fire & Flushing/Fire & Bilge, Ingersoll-Rand Co., Centrifugal, 200 GPM, 100 PSI, 3500 RPM. Motor Data: General Electric Co., 20 HP, 3500 RPM, 440 VAC). Pump Diesel Oil Transfer, Pump Diesel Oil Service, 2 Sharples Purifier lube oil/fuel oil.

The focus of the restoration effort has been on the aft machinery spaces. It is anticipated that B-1 will be one of the last spaces restored aboard the SLATER.
