The Argus Umbilical Sheave is designed to make a safer work environment for personnel and equipment. The use of a sheave will drastically reduce damage to the fiber optic umbilical caused by pulling the cable over the vessel railing with tension. The sheave is hung in the crane and moved out to the side of the vessel. Minimum bend radius of the umbilical cable will not be exceeded using the sheave. Plastic rollers will make sure the cable moves freely over the sheave.
