Choosing a Rig Transportation System
If you're in the oil and gas industry, you know how important a good rig transportation system is. Moving drilling rigs and other heavy oilfield equipment is a big part of the job, and you need a safe, efficient way to do it. Whether you're moving a workover rig between wells, or moving a full drilling rig across the country, the right transportation system makes all the difference. Here's what you need to know to choose the right one.
Types of Rig Transportation Systems
Truck and Trailer Systems. This is the most common way to move rigs. You load the rig equipment onto heavy-duty trucks and lowboy trailers, and drive it to the next location. It's flexible, it works for long distances, and it's well-established. But it's slow, and it requires disassembling the rig.
Self-Propelled Modular Transporters (SPMTs). These are huge, multi-axle trailers that can carry enormous loads. They're used for moving very large, very heavy equipment — like big drilling rigs, refinery modules, and offshore platform components. They're more expensive than regular trucks, but they're the only way to move really big loads.
Hydraulic Skidding Systems. These are for moving rigs short distances on the well site. They use hydraulic cylinders to lift and slide the rig. They're not for long-distance transportation — they're for moving the rig a few hundred meters from one well to the next.
Walking Systems. These are like skidding systems, but they move the rig on "legs" instead of sliding it. They're newer technology, and they're popular on modern drilling rigs. They can move the rig forward, backward, and sideways, which is very handy.
What to Consider When Choosing a System
When you're choosing a rig transportation system, think about:
- Distance: How far are you moving the rig? Short distances can use skidding or walking systems. Long distances need trucks.
- Size and weight: How big and heavy is the rig? Bigger, heavier rigs need bigger, stronger transportation systems.
- Terrain: What's the ground like? Is it flat, or hilly? Is it paved, or rough dirt roads?
- Budget: How much can you spend? Truck systems are the cheapest. SPMTs and walking systems are more expensive.
- How often do you move: If you move the rig every week, a walking or skidding system will pay for itself quickly. If you move it once a year, just use trucks.
FAQ
Q: How much does it cost to transport a drilling rig?
A: It depends on the size of the rig and the distance. A short move within an oilfield might cost $10,000 to $50,000. A long-distance move across the country can cost $100,000 to $500,000 or more. It's a significant expense, which is why faster rig-moving technology is so valuable.
