What is a second order moment?

The second order moment acts only in the vertical direction and precaution needs only be 
considered for 4, 5 and 6 cylinder engines. Resonance with the 2nd order moment may only 
occur at hull vibrations with more than 3 nodes. A 2nd order moment compensator 
comprises two counter rotating masses running at twice the engine speed.
