Solution Overview

Problem

Wellbore servicing tools, such as components of an electrical submersible pump assembly, are prone to damage during transport and require extensive testing and maintenance, which is time-consuming and labor-intensive, increasing the risk of further damage and delays.

Innovation Solution

A transport assembly comprising a reinforced transport basket with clamps, lift supports, and braces that securely holds and supports ESP components, allowing for efficient testing and preparation while minimizing damage, and enabling safe handling and stacking for transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ESP components are transported without a reinforced transport assembly, then transport simplicity is maintained, but damage risk to components increases

Engineering Contradiction:

Improvecomponent integrityVSAvoidtransport assembly structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The transport assembly is divided into modular components including a transport basket, braces, clamps, and lift supports that can be independently configured and assembled based on specific component protection needs

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The reinforced transport assembly provides pre-established structural protection through braces and clamps before components are subjected to transport stresses, preventing damage rather than remedying it after occurrence

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If ESP components are lifted and handled multiple times for testing and maintenance, then thorough inspection is achieved, but time consumption and labor requirements increase

Engineering Contradiction:

Improvecomponent functionalityVSAvoidtesting and maintenance duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Multiple functions including transport, support during testing, and maintenance positioning are merged into a single integrated transport assembly, eliminating the need for separate handling operations for each function

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The transport assembly serves multiple purposes: transporting components to the wellsite, providing structural support during testing, and facilitating maintenance operations, thereby reducing overall time and labor requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If multiple field service crew members are deployed for component handling, then safe operation is ensured, but labor costs and operational complexity increase

Engineering Contradiction:

Improvesafe operationVSAvoidoperational efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The lift supports enable dynamic height adjustment of the transport basket, allowing single operator control of heavy components through mechanical advantage rather than requiring multiple workers for manual handling

Inventive Principle:

Principle #15Dynamics

AI summary

A method of testing an electrical submersible pump (ESP) component may include placing an ESP component in a transport assembly at a first location for transport to a second location. The ESP component may be tested or maintained while the ESP component remains in the transport assembly, before being deployed at a wellsite. The ESP components can be prepared in the transport assembly to be lifted (including placement of lifting clamps) to run in hole. In various embodiment, the transport assembly may comprise the ESP component and a transport basket configured for stacking multiple transport assemblies.
