3 Ballot Comments and Resolution Ballot: 1845 Name: 4F 3rd Ed - Service Rig Rating Report Date: 11/10/2009 Closing Date: 10/30/2009 Sort Key Name Proposal: Vote Section Type Clause Subclause Number Type of Comment Comment Proposed Change Comment Resolution 1 Barr, Stephen Guest All Sections General I don't understand the reason for the creation of two classes of masts. If a service rig is used for drilling (as many are), then can it be classified as a drilling structure and avoid all of the extra requirements? Do not go forward with the proposed changes The comment and proposed changed are considered non-persuasive. The change was initiated at the request of a number of manufacturer's to reflect ratings practices under previous versions which they felt were useful. The ballot item defines new ratings for masts that allow a user to determine safe usage of his rig for combinations of hook load, wind, rod loads and setback; it also includes the requested rating for hook load alone with operating wind, which is likely to be a somewhat higher rating than would be possible with rod and setback."
