Derrick structures are the backbone of drilling operations, and ensuring their structural integrity is not just a compliance issue—it’s about preventing accidents, minimizing downtime, and safeguarding your crew. Unfortunately, many inspections miss critical elements that lead to long-term damage or even catastrophic failure.

In this blog, we’ll explore the essential structural integrity checks every derrick inspection must include—whether you’re working offshore or onshore. We’ll also show how digitizing your inspection workflow with tools like InspectionsTrack can help ensure no detail slips through the cracks.

Why Structural Integrity Checks Are Non-Negotiable

Derricks endure constant stress from wind, vibrations, mechanical operations, and heavy equipment loads. Over time, wear and tear on bolts, welds, and joints can compromise safety.

Neglecting key inspection points can result in:

• Dangerous collapses or failures
• Costly repairs or unplanned shutdowns
• Non-compliance with industry standards like API RP 4G

That’s why a standardized, detailed inspection checklist is essential—and better yet, digitized.

Must-Check Structural Points During Derrick Surveys

Here’s a breakdown of the most critical structural integrity checkpoints to cover during your derrick survey:

Structural Component	What to Check	Why It Matters
Main Legs and Cross Bracing	Cracks, corrosion, deformation, or loose bolts	Core load-bearing structure; issues here can trigger collapse
Welded Joints	Visual cracks, fatigue, undercuts	Weak joints increase risk of detachment or bending
Guy Wires and Anchors	Tension, corrosion, wear, or misalignment	Maintains vertical stability of derrick
Crown Block Support	Fatigue cracks, bolt tension, alignment	Supports hoisting system, vital for safe lifting
Ladder Systems & Safety Cages	Rust, damage, or loosened fittings	Crucial for personnel safety during climbing
Derrick Base	Settlement, alignment, or foundation cracking	Affects overall stability and vertical load transfer
Bolt Torque & Fasteners	Torque values, missing or loose nuts/bolts	Keeps all structural components secured

Common Oversights That Lead to Failures

Unfortunately, many teams still use manual spreadsheets or paper checklists that are easy to overlook or forget to update.

Some of the most common oversights include:

• Failure to inspect areas under load or in hard-to-access zones
• Ignoring subtle fatigue signs in older welds
• Skipping torque checks for structural bolts
• Relying on outdated inspection templates

Over time, these oversights compound into serious safety risks.

How to Ensure No Checkpoint Is Missed (Even in Harsh Environments)

One of the easiest ways to ensure consistency and completeness in your derrick inspections is to use a centralized digital inspection system like InspectionsTrack.

How InspectionsTrack Helps:

• Smart Checklists tailored to API RP 4G and other industry standards
• Offline Mode so inspections can be done on remote sites
• Auto Sync when internet becomes available
• Photo Uploads and condition tags for every structural point
• Historical Data Access to spot trends or recurring issues
• AI-Powered Suggestions for potential failure risks

By digitizing the process, you eliminate human error, improve accountability, and create a clear audit trail for compliance.

Tips for Better Structural Integrity Audits in Derrick inspections

Here are a few expert tips to take your derrick surveys to the next level:

• Always use calibrated torque wrenches for bolt verification
• Train teams to spot early fatigue signs in welds and beams
• Cross-check survey findings with previous inspection data
• Capture images and use tagging software for documentation
• Schedule inspections during both static and operational modes
