DESCRIPTION The main drive of the tanker, HERMAN FALK, consists of two 8-cylinder, enclosed, trunk type, Falk re- versible diesel engines connected by means of Falk flexible couplings to a reduction gear unit located at the for- ward end of the en- gine. Reversing, start- ing and speed control is common to both en- gines which handle ex- actly as one_ unit. 431 ft.; Beam—59.2 ft.

E. generator, direct connected Remarks The conversion of the tanker HERMAN FALK (ex TUXPANOIL) was carried out at the Sparrows Point plant of the Bethlehem Shipbuilding Corp. under C. E. Ross, marine consulting engineer, New York. The interesting twin diesel engine geared unit installed was designed by O. A. Banner, engineer and manager of the oil engine department of the Falk Corp. The port and starboard boilers were retained and the center one removed. The HERMAN FALK carries oil in bulk, having already made a number of successful trips, is owned by the Oil Transport Co., and operates on charter.
