Solution Overview

Problem

In offshore and onshore drilling operations, connecting high-pressure fluid conduits to elevated cement or fracturing heads poses safety risks and inefficiencies due to the need for manual labor at elevated positions, which can result in accidents and increased downtime.

Innovation Solution

An automated connection assembly featuring a winch system and quick-lock receptacle allows for remote operation, lifting, and secure attachment of fluid conduits to cement or fracturing heads, eliminating the need for personnel to access elevated locations and reducing connection time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual labor is used to connect fluid conduits to elevated cement or fracturing heads, then connection can be achieved, but safety risks increase due to personnel exposure to hazards at elevated positions

Engineering Contradiction:
ImprovesafetyVSAvoidmanual access requirement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces manual mechanical connection operations with an automated robotic system. The robotic manipulator performs the connection tasks that previously required human operators to physically access elevated positions, thereby eliminating safety risks while maintaining operational capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a robotic manipulator as an intermediary between the control system and the fluid conduit connection process. This intermediary performs the dangerous manual tasks at elevated positions, protecting human operators from hazards while enabling precise connection operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If manual connection procedures are used, then connection can be made, but connection time increases leading to decreased operational efficiency

Engineering Contradiction:
Improveconnection speedVSAvoidconnection time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The robotic system performs connection operations autonomously without requiring human intervention for each connection task. The system can independently position, align, and connect fluid conduits to elevated equipment, significantly reducing connection time and improving operational efficiency.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

By replacing manual connection procedures with automated robotic manipulation, the system achieves faster and more consistent connection speeds. The robotic manipulator can perform repetitive connection tasks more quickly and with greater precision than manual operations, thereby reducing overall connection time.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If personnel access elevated positions for connection tasks, then connection can be performed, but risk of accidents and dropped objects increases

Engineering Contradiction:
Improveaccident riskVSAvoidpersonnel access
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent extracts human operators from the hazardous elevated work environment by deploying a robotic manipulator to perform connection tasks. This removes the source of harm (human personnel) from the dangerous location while maintaining the necessary operational functions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The robotic manipulator serves as an intermediary that performs connection operations at elevated positions without exposing human operators to hazards. The system can safely handle heavy components and perform precise maneuvers in environments that would be dangerous for human workers.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A connection assembly (10) for automated lifting and positioning of a chiksan (110) or other fluid conduit in proximity to a fluid inlet (60) of a device such as, for example, a cement (100) or hydraulic fracturing head. Once a chiksan or other flow line is positioned in a desired location, a secure connection is made between the outlet of the chiksan or other fluid conduit and the fluid inlet including, without limitation, when the device is positioned at an elevated location above a rig floor.
