Calculate New Load - rig application

In summary, the problem involves a rig accelerating a load of 200,000 lbf from zero to 60 ft/min in 5 seconds. The equation used to calculate the new load shown on the hook load indicator is P-T = ma, and the distance of the load is calculated to be 4.99 ft. The acceleration is vertical and the tension in the cable is caused by the weight of the load and the extra force needed for acceleration.

Can you please show more of your work? Can you attach a diagram of the problem? Is all of this acceleration vertical?

Hello Berkeman:

Thank you for your reply. I don't have a diagram attached. Yes the acceleration is vertical. The hook lowers/hoist loads vertically in a drilling rig.

So the two things creating the tension in the cable is the weight of the load, and the extra force needed to generate that acceleration. Can you start to write down the equation for the total force on the accelerating object now? :smile:

Yes.

P-T = ma
 

Related to Calculate New Load - rig application

1. What is a "calculate new load" and why is it important in rig applications?

A "calculate new load" refers to the process of determining the weight that a rig can safely support based on various factors such as equipment, materials, and environmental conditions. It is important in rig applications to ensure the safety of workers and prevent equipment failures or accidents.

2. What factors are considered when calculating a new load for a rig application?

Factors that are commonly considered when calculating a new load for a rig application include the weight of equipment and materials being lifted, the type of rig being used, the location and terrain of the site, and any potential environmental hazards such as wind or extreme temperatures.

3. How is the new load calculated for a specific rig application?

The new load is typically calculated using specialized software or formulas that take into account the various factors mentioned above. The calculations may also be done manually, but this can be time-consuming and may not be as accurate.

4. Can the new load calculation change during the duration of a rig application?

Yes, the new load calculation can change during the duration of a rig application due to factors such as changes in equipment or materials being lifted, or changes in environmental conditions. It is important to regularly recalculate the new load to ensure the safety of workers and prevent any accidents or equipment failures.

5. What are the consequences of not accurately calculating the new load for a rig application?

Not accurately calculating the new load for a rig application can lead to serious consequences such as equipment failures, accidents, or injuries to workers. It can also result in damage to the rig and surrounding structures, and potentially halt the progress of the project. It is crucial to always ensure accurate new load calculations to maintain safety and efficiency in rig applications.
