Buying a Derrick? The Procurement Checklist I Use Before Approving Any Quote

Let me save you some time: if you searched for 'derrick harmon father', 'derrick jefferson', '2020 lincoln', 'monarch', or 'hawk vs eagle vs', this article isn't for you. That's fine.

If you're here because your drilling operation needs a derrick—the mast structure that holds the top drive—this checklist is what I use before approving any equipment quote. I'm a procurement manager at a 300-person oilfield services company. I've managed our capital equipment budget for seven years, negotiated with 30+ vendors (maybe 35, I'd have to count), and made a few of the mistakes below more recently than I'd like to admit.

When This Checklist Applies

Use this checklist when you're buying a replacement derrick with the same basic rig footprint: similar height, similar static hook load range, and a conventional mast configuration. It works for both new and well-documented used equipment. It does not work if you're designing a custom offshore mast or a new modular drilling package from scratch. In those cases, you need a structural engineer and a proper design basis, not a procurement checklist.

That's not false modesty. It's the same reason I wouldn't ask an accountant to design a mud pump. Knowing when a tool doesn't apply can save you more than the tool itself.

The 6-Step Derrick Buyers Checklist

1. Lock Down the Operating Envelope Before You Talk Price

Every vendor will ask for a derrick height and rough load. That's not enough. I write down the full set: static hook load, wind speed rating, setback loads, drilling line pull, racking board capacity, and clearance for the traveling equipment.

In 2023, when we audited our replacement plan, our engineer caught that we were planning a heavier top drive the following year. That changed the static hook load requirement by about 12%. We caught it before the quote, not after. That's what step 1 is for.

2. Ask For a Fully Itemized Quote Scope

A quote that says 'fully equipped' without listing what 'fully' means is a quote that will surprise you. I want each vendor to break out the major components: mast sections, base, water table, crown platform, racking board, access ladder with rest platforms, fall protection, coating system, and any attachment steel for the specific rig.

If a vendor won't itemize, that's a sign they don't want you comparing the details.

3. Compare Total Cost of Ownership, Not Sticker Price

Sticker price is only part of the story. In a recent bid, Vendor A quoted $187,000 delivered. Vendor B quoted $162,000 before we added freight, commissioning, a spare parts package, and a post-startup service visit. When we itemized B's full list, it came to about $202,000. Vendor A wasn't the cheapest line item; it was the cheapest total cost.

If you're not including transportation, rigging, site prep, inspection travel, and the cost of a potential delay, you're not comparing quotes. You're comparing soundbites.

4. Verify the Paper Trail Before Any Down Payment

This is the step most buyers skip. I understand why; the load charts all look similar, and no one wants to slow down an approval to ask for documents. But the documentation is where the real differences are.

For a new derrick, ask for the load test certificate with the actual date and applied load, NDT reports for critical welds, material certificates for load-bearing members, and a manufacturer's declaration of conformity. For a used derrick, ask for the most recent inspection report and proof that any required repairs were done. I assumed 'same specifications' meant the same documentation. It didn't. One vendor had a clean certificate; the other could only produce a summary sheet.

5. Put Freight and Site Logistics Into the Same Spreadsheet

A 147-foot derrick is not a normal truckload. If you're moving it across state lines, you may be dealing with overweight and over-dimensional permits, route surveys with bridge clearance checks, utility line clearance, and a crane that actually has the reach to set it up.

I made the mistake of assuming a high quote with 'free shipping' included a full route survey. It didn't. The truck driver called us at the state border and said a bridge was too low. That delay cost more than the survey would have.

6. Do a Hands-On Inspection Before the Final Milestone Payment

When the derrick arrives, don't sign off based on crate photos. Walk the structure and check for damage, corrosion, missing bolts, and any signs the coating got touched up without the underlying metal being addressed. For a used derrick, it is worth paying a third-party inspector with calibrated ultrasonic testing equipment to check thickness on the critical areas.

There is something satisfying about catching a corroded ladder before the funds move. It feels much better than catching it after the supplier has been paid.

Common Mistakes I Keep Seeing in Purchase Approvals

• Treating all vendors' 'standard specifications' as identical. They are not. Coatings, bolt grades, and inspection requirements vary even when the main load chart says the same thing.
• Not connecting the delivery date to your actual project deadline. I said 'as soon as possible' on one order; the vendor heard 'whenever convenient.' The result was a delivery after our permit window closed.
• Making progress payments based only on a calendar instead of on completed milestones with attached documentation.
• Assuming the warranty covers installation damage. It often doesn't, and that becomes your cost, not the manufacturer's.

This checklist won't tell you which derrick is 'best.' No honest buyer can, without knowing your rig profile, your well program, and your budget constraints. But it will help you get to the right comparison.

If you arrived here through one of those unrelated searches, no hard feelings. If you arrived here because you're about to approve a derrick purchase, start with step 1 and do not skip step 4. That's where the bad surprises live.
