A precision cable handling system to measure varying tension on a ship based cable-laying system. The system must provide accurate horizontal force measurement without interference from vertical loads, while compensating for vessel trim, roll and pitch.

The solution is applicable to Linear Engines (see picture), Drum Winches, and Draw Off Hold Back Engines (DOHBs). High resolution AST load cell instrumentation, combined with KIS Weigh Module accuracy, provides the ideal solution to this problem. The KIS measurement axes are aligned horizontally to measure the horizontal tension. High linear engine dead weight is ignored by the unique KIS Beam design, which rejects side loads. The System includes pitch compensation, which eliminates measurement inaccuracy due to motion of vessel.

A wide range of tensions must be measured with high accuracy on fiber optic cable deployed from an oceangoing vessel. In addition to wide rangeability, the system must also accommodate a high dead weight to tension force ratio. Although fiber optic cables carry many more channels of information than their equivalent copper counterparts, they are much more sensitive to excessive tension. Over stressing drastically affects the cable's transmission characteristics.
