The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.

Video Safehaven Marine 'Independent Vision' pilot boarding

published on 8 June 2020

We also undertook some alongside handling trials at the same time with ‘San Cibrao’ before she is shipped to Spain.
