5.1 All Polar Class ships should be provided with
directional control systems of adequate strength and suitable design
to enable efficient operation in Arctic ice-covered waters.
5.2 For the purpose of this chapter, a directional
control system includes any device or devices intended either as a
primary or auxiliary means of steering the ship. The directional control
system includes all associated power sources, linkages, controls and
actuating systems.
5.3 Attention is drawn to the possibility of interaction
between directional control systems and propulsion systems. Where
such interaction occurs or where dual purpose components are fitted,
the provisions of chapters 7 and 8 should also be complied with, as
applicable.
