The SEC Fairtrans fairleads, designed for two ropes may have te be selected based upon the ship design or the occurring line angles.
Compared to the fairleads designed for one rope, the basic 7-roller fairlead (Type FA-D) can be modified by adding either one, two or three additional vertical rollers.
The choice of where and how many extra rollers are required depends on the existing line-angles of the mooring lines. If necessary, horizontal rollers can be added to the double fairleads to overcome differences in height.
