X82DF-A-1.0

Main driver for VLCC, VLOC, VLAC and Post-Panamax container vessels due to its extended rating field

The low engine speed of 58rpm offers an increased flexibility for selecting the most efficient propeller diameter and propeller speed for VLCC’s and VLOC’s whereas the higher engine speed up to 84rpm is suitable for Post-Panamax Container vessels.
X82-DF-A-1.0 is available in 6 to 9 cylinder configuration, covering a power range from 16,560 to 49,500 kW at 58 to 84rpm.
