A method of stabilizing a riser includes applying an oscillating force to the riser, using one or more thrust units on the rise, so as to counteract oscillating movement of the rise, preferably having a first component oscillating at a period between 3 and 20 seconds and a second component oscillating at a period between 1 and 5 minutes, where the thrust units may be positioned at antinodes of the oscillating movement and preferably each comprise three pairs of thrusters respectively configured to provide thrust in three evenly spaced directions.
