Desktop rig review can be performed onboard or remotely. We perform such scope for the following types of rigs:

• Drillships (including last generations)
• Semisubmersibles
• Jackups (including last generations)
• Tender Assisted Rig
• Swamp Barges
• Land Drilling Rigs
• Land Workover Rigs
• Snubbing and Lifting Units

Detailed scopes for each type are available upon request.

Desktop Rig review can be performed any time, for any rig situation.

Usually, our customers prefer such scope for the following situations:

• Major doubt on rig certification status
• Review of rig certification (after initial job onboard)
• Narrowing rig list during tendering process (to make short list)
• After rig major maintenance, modification or refusbishment
• Scope to include Rig Design Review of major design change
• In preparation for Rig Capacity Study (to confirm rig capacity to perform a specific well program)

Detailed scopes for each situation are available upon request.

Our inspection team can perform such scope onboard or remotely, provided that drilling contractor provides all required documents. The review will focus on the following:

• Original Certification of major rig equipment, including well control equipment
• Last Recertification of rig major equipment, including well control equipment
• Last Overhauls of major equipment (mast/sub, blocks, top drive, drawworks, mud pumps, engines, generators, electrical drive motors…)
• Last major maintenance records of the other rig equipment
• Analysis of corrective maintenance records
• Analysis of rig downtime/NPT
• Analysis of all provided maintenance records

Detailed desktop review scope is available upon request.

We also provide specific Rig Capacity Verification: a full study to confirm rig actual available power and capacities to perform a specific type of wells, especially when high power consumption is expected.
