What is a rig inspection?
Rig inspections, also known as rig audits, are conducted on drilling assets for both drilling contractors and drilling operators to assess the condition of an asset. Rig inspections are conducted to industry standards, such as API, as well as to specific client requirements.
What is included in a drill rig inspection checklist?
Drilling Rig Rotating Equipment Inspection Checklist, which includes the following: Rotary Table (Rt), Driller Control Instruments (DCIS) (Check also Driller Job Descriptions), Iron Roughneck Ir, Pipe Spinner Ps (If Applicable), Drill String Components (Tested As Per Api Rpg), Other Drilling Equipment, Top Drive.
Who conducts rig inspections?
Rig inspections can be conducted by either the owner or operator of a drilling asset. Services for rig commissioning are conducted prior to the equipment entering service. This can be at the end of construction or during major overhauls and five-yearly inspections.
What is rig inspection & rig commissioning?
Rig inspection and rig commissioning are critical to the oil and gas industry. Rig inspections can be carried out both before the hiring of a drilling asset and during the contract. A pre-hire rig inspection/audit assess the condition and suitability of the asset for a drilling contract.
What inspections do drilling rigs undergo?
At the commissioning stage, drilling rigs undergo inspections for acceptance. These usually include inspections of critical systems such as the prime movers that produce energy for the rig, rig floor testing, blowout prevention control systems review, stack acceptance pressure tests, and many other detailed audits.
When should rig inspections be carried out?
Rig inspections can be carried out both before the hiring of a drilling asset and during the contract. A pre-hire rig inspection/audit assess the condition and suitability of the asset for a drilling contract. During the contract, rig inspections assess both the asset’s operational condition and its compliance with the terms of the contract.
Mast in drilling rig
The mast is normally used on land drilling rig types requiring a good deal of mobility; they are rarely used on offshore rigs. The racking board is in a cantilever position and lengths of drill pipeare racked on a floor, called the setback, that is separate from the mast structure. Most masts have one side open (window side),. . There are different types of masts for land drilling and service rigs: 1. Folding Type 2. Telescopic Masts 3. Bootstrap Type 4. Portable/Cantilivered masts (Non-Guy line) . Figure 8 shows a telescopic mast. Telescopic masts with their drawworks and engines are usually mounted on trucks or trailers. The load should be borne by hydraulic or. . Each structure shall be rated for the following applicable loading conditions. The following ratings do not include any allowance for impact. Acceleration, impact, setback, and wind loads will reduce the rated static hook load capacity. Technical specifications are identical to those for derricks: 1. Maximum hook load given the reeving system, 2. F. . For conventional Mast (Land rig), the below pictures show the erection sequence of rigging up For rigging up the vertical mast, the below pictures show the bootstrap sequence of rigging up. [pdf]
