Of course, in many contracts, they may delete or add new terms. But that entails a modest effort as the rest of the standard terms of the contract will be used. Nowadays, information may be vital for the contract and the skill of the lawyer will be demonstrated through the use of the information. For example, in off-shore operations, a distinction is drawn between a wet and a dry tow. In the latter, the rig or equipment is placed on a barge which is towed, pushed or pulled by a tug.
Accidents frequently occur as a result of the parting of the tow-rope.
If the tow-rope is long, the tow will be unmanageable and could be lost. If it is short, the tow could collide with the tug. A computer program has been developed to show the exact length and thickness of the tow-rope. Other examples could be cited, for instance the so-called permissible loss in the transport of oil. A computer program takes account of the age of the tanker, the duration of the voyage, the quantity of oil, the grade, etc., and determines the exact percentage of loss.
