Compliance. The manufacturer is responsible for complying with all of the
provisions of the specification.
Supplementary Requirements
Magnetic Particle Examination. All accessible surfaces of the main load
carrying components of the equipment shall be examined by a magnetic particle
examination method or technique conforming to the requirements of ASTM
E709: “Recommended Practice for Magnetic Particle Examination.” Acceptance
limits shall be as agreed upon by the manufacturer and the purchaser.
Liquid Penetrant Examination. All accessible surfaces of the main load carrying
components of the equipment shall be examined by a liquid penetrant examination
or technique conforming to the requirements of ASTM E165: “Recommended
Practice for the Liquid Penetrant Examination Method.” Acceptance
limits shall be as agreed upon by the manufacturer and the purchaser.
Ultrasonic Examination. Main load carrying components of the equipment shall
be ultrasonically examined in accordance with applicable ASTM standards. The
extent of examination, method of examination, and basis for acceptance shall
be agreed upon by the manufacturer and purchaser.
Radiographic Examination. Main load carrying components of the equipment
shall be examined by means of gamma rays or x-rays. The procedure used shall
be in accordance with applicable ASTM standards. Types and degrees of
discontinuities considered shall be compared to the reference radiographs of
ASTM as applicable. The extent of examination and the basis for acceptance
shall be agreed upon by the manufacturer and purchaser.
Traceability. The manufacturer shall have reports of chemical analysis, heat
treatment, and mechanical property tests for the main load carrying components
of the equipment.
Welding. Where welding is involved in the critical load path of main load
carrying components, recognized standards shall be used to qualify welders
and procedures.
Extreme LOW Temperature. Equipment intended for operation at temperatures
below 0°F may require special design and/or materials.
Inspection
Hoisting Tool Inspection and Maintenance Procedures
Frequency of Inspection. Field inspection of drilling, production, and workover
hoisting equipment in an operating condition should be made on a regular basis.
A thorough on-the-job shutdown inspection should be made on a periodic basis,
typically at 90 to 120-day intervals, or as special circumstances may require.
Critical loads may be experienced; for example, severe loads, impact loads
such as jarring, pulling on stuck pipe, and/or operating at low temperatures.
If in the judgment of the supervisor a critical load has occurred, or may occur,
an on-the-job shutdown inspection equivalent to the periodic field inspection
should be conducted before and after the occurrence of such loading. If critical
