API SPEC 8C

Abstract

This International Standard provides requirements for the design, manufacture and testing of hoisting equipment suitable for use in drilling and production operations. <br>This International Standard is applicable to the following drilling and production hoisting equipment: <br>a) hoisting sheaves; <br>b) travelling blocks and hook blocks; <br>c) block-to-hook adapters; <br>d) connectors and link adapters; <br>e) drilling hooks; <br>f) tubing hooks and sucker-rod hooks; <br>g) elevator links; <br>h) casing elevators, tubing elevators, drill-pipe elevators and drill-collar elevators; <br>i) sucker-rod elevators; <br>j) rotary swivel-bail adapters; <br>k) rotary swivels; <br>l) power swivels; <br>m) power subs; <br>n) spiders, if capable of being used as elevators; <br>o) wire-line anchors; <br>p) drill-string motion compensators; <br>q) kelly spinners, if capable of being used as hoisting equipment; <br>r) pressure vessels and piping mounted onto hoisting equipment; <br>s) safety clamps, if capable of being used as hoisting equipment; <br>t) guide dollies for traveling equipment (e.g. hooks, blocks, etc.). <br>This Standard establishes requirements for two product specification levels (PSLs). These two PSL designations define different levels of technical requirements. All the requirements of Section 4 through Section 11 are applicable to PSL 1 unless specifically identified as PSL 2. PSL 2 includes all the requirements of PSL 1 plus the additional practices as stated herein. <br>Supplementary requirements apply only when specified. Annex A gives a number of standardized supplementary requirements.
