API RP 95J (R2020)

The purpose of this recommended practice is to present an approach to siting Jackup Mobile Offshore Drilling Units (MODUs) and to recommend certain operational procedures to enhance Jackup survivability and stationkeeping during hurricane season in the Gulf of Mexico during drilling, workover and while stacked (idled) at a non-sheltered location. This RP provides guidance and processes and when combined with an understanding of the environment at a particular location, the characteristics of the unit being utilized, and other factors, may be used to enhance operational integrity. This RP was developed through a cooperative arrangement with the International Association of Drilling Contractors’ (IADC) Jackup Rig Committee. Specifically, this RP provides guidance in the following areas:

• Site – including location-specific, geotechnical, and metocean;
• Preloading Process;
• Air Gap Recommendations;
• Unit Preparations and Evacuation;
• Post Storm Recovery;
• and Post Storm Inspections.
