API Spec 8A:1997 pdf download.Specification for Drilling and Production Hoisting Equipment
1 Scope
1.1 DESIGN RATING BASIS This specification provides a basis for establishing the ratings of main load carrying components of certain hoist- ing equipment used in drilling and production operations as follows: 1.1.1 Maximum Load Rating This is a calculated maximum load rating using a pre- scribed design safety factor on the minimum yield strength of the material used in the equipment. This load rating is not intended to fix the expected service life other than by provid- ing a reasonable margin of safety against failure. CAUTION: The terms safety factor or design safety factor are intended as design criteria and should not under any circum- stances be construed as allowing loads in excess of the maxi- mum load rating as established under this specification. 1.1.2 Bearing Load Rating This is a calculated maximum load main-bearing rating for traveling blocks, and swivels. This bearing rating is intended primarily to achieve consistency of ratings, but is also intended to provide a reasonable service life for such main bearings when used at loads within the equipment rating. 1.1.3 Design Criteria This specification provides for a method of rating main load carrying components of certain hoisting equipment used in drilling and production operations, predicated on normal field loading in which the following conditions are assumed to exist: a. The maximum load rating includes all static loads encoun- tered in the operation of the equipment. It should be recognized that dynamic loads exist and if the combined static and dynamic loads exceed the maximum safe working load, the safety factor will be reduced accordingly. b. The fatigue limit of the material in the equipment and the effect of stress risers are recognized as important factors in design. c. The ratings determined herein are intended to apply to new equipment only.
1.3 SUPPLEMENTARY REQUIREMENTS
This specification also covers a group of supplementary requirements which may be applied to equipment manufac- tured under the provisions of this specification. These are meant to be used when additional testing or inspection is desired and apply only when specified individually by the purchaser in the inquiry, contract, and order. Details of these requirements shall be as agreed to by the manufacturer and purchaser.
