As we mentioned in the Rig Audit Article, rig inspection is an important process that shall be done from time to time. Especially, after the rig moving to a new drilling location. Here we have collected drilling & workover rig inspection & maintenance checklists for onshore and offshore rigs ( including jack up rigs & according to API and Osha recommendations).
Please Subscribe with your e-mail to get the latest drilling articles and job vacancies
Also please take in your consideration that various items on these checklists are shaded grey. (this is an INDICATION ONLY of items that are LESS safety-critical to check). Therefore, by default, the remaining items are the more safety-critical ones.
The major rig acceptance procedures are as following:
- Prime movers acceptance inspection
- Cementing unit acceptance inspection
- Chock manifold acceptance pressure test
- Bop stack acceptance pressure & function tests
- Bop control system acceptance
