Manufacturing Documentation Improvements & Process Standardization

While working at Swagelok, I led significant improvements to the quality, consistency, and utility of production documentation used for fabrication, inspection, assembly, and testing of high-purity gas handling systems.

A long-standing issue within production operations involved fabricated sheet metal components arriving from suppliers with dimensional discrepancies or missing features, often requiring rework or replacement after receipt. Many of the existing production drawings lacked consistent GD&T standards, detailed fabrication references, or sufficient inspection documentation.

To improve manufacturing quality and communication, I revised and standardized production drawing practices across multiple product lines. This included updating drawings to modern GD&T standards, incorporating P&IDs and weld maps directly into production packages, and developing helium leak testing documentation to support final inspection and quality verification processes.

I also worked closely with outside fabrication vendors and internal inspection personnel to ensure suppliers consistently received current and accurate drawing packages, and that incoming inspectors had the necessary documentation to properly verify manufactured components upon receipt.

These improvements significantly reduced recurring fabrication issues, improved manufacturing communication between engineering and suppliers, and provided assemblers and inspectors with more complete process documentation throughout production and testing operations.

Major Highlights:

  • Improved production drawing quality and standardization for high-purity gas handling systems

  • Updated drawings to current GD&T standards

  • Added P&IDs, weld maps, and helium leak testing documentation

  • Improved communication between engineering, suppliers, inspectors, and assembly teams

  • Ensured suppliers consistently received current and accurate fabrication drawings

  • Reduced recurring sheet metal fabrication and rework issues

  • Improved inspection and assembly documentation throughout production

  • Increased manufacturing efficiency by providing clearer production references

Production Efficiency & In-House Manufacturing Improvements

While working at Swagelok, I developed and implemented several tooling, fixture, and process improvements intended to increase manufacturing efficiency, reduce outsourcing requirements, and improve support for production and testing operations within the shop.

These projects ranged from custom orbital welding tooling to 3D printed production fixtures and helium leak testing components. Many of the improvements were developed and implemented with short lead times to quickly address production needs and improve day-to-day manufacturing operations.

One project involved the development of adjustable orbital welding tube supports used during fabrication of high-purity tubing assemblies. The supports improved setup consistency and reduced fabrication difficulties during welding operations. Multiple production-ready sets were manufactured and implemented internally, reducing cost and lead time compared to commercially sourced alternatives.

I also designed and produced a 3D printed laser engraving fixture that allowed stainless steel identification tags to be engraved in-house rather than outsourced. The fixture improved engraving consistency, reduced turnaround time, and simplified repeat production operations.

In support of helium leak testing operations, I designed a replacement Delrin test fitting to replace a legacy component that was no longer commercially available. The new fitting restored testing capability while improving long-term maintainability of the leak testing process.

These projects contributed to improved production flexibility, reduced outsourcing dependence, and increased support for internal manufacturing and testing operations. In recognition of these efforts and other process improvements, I was awarded a company Certificate of Appreciation for innovative contributions.

Hydraulic Motor Failure Investigation - Root Cause Analysis & Process Improvement

During commissioning of several hydraulic dredging systems, a specific model of bent-axis axial piston hydraulic motor began experiencing premature failures during field startup and operation. The failures occurred shortly after the equipment was placed under load at customer sites, resulting in damaged internal components, equipment downtime, and costly field replacements.

As part of the engineering team at Ellicott Dredge Technologies, I worked directly with manufacturing personnel, field service teams, and the hydraulic motor supplier to investigate the failures and determine the root cause.

Initial investigation revealed that although the motors had been functionally tested in-house prior to shipment, the testing process did not fully simulate actual operating conditions experienced in the field. The motors were not being run long enough to fully lubricate all internal moving components, and they were not subjected to representative operating loads during shop testing.

Once the dredges were started under full operational load at customer sites, insufficiently lubricated internal piston components experienced galling and rapid failure.

To support the investigation, I traveled to multiple customer sites to retrieve failed motors, oversee replacements, and document field operating conditions. I then worked directly with the motor manufacturer to deconstruct and analyze the failed units as part of a formal failure analysis process.

Following the investigation, we revised the startup and testing procedures used during in-house commissioning to better simulate real operating conditions. This included extended runtime requirements, revised startup sequencing, and application of representative operating loads during testing.

The updated procedures successfully eliminated the recurring failures and significantly improved field reliability during startup and commissioning operations.

Major Highlights:

  • Investigated hydraulic motor failures during dredge commissioning

  • Performed root cause analysis with supplier and field teams

  • Identified insufficient lubrication and unrealistic shop testing conditions

  • Retrieved failed motors and supported field replacements

  • Coordinated teardown inspections and failure analysis

  • Revised startup and commissioning procedures

  • Implemented extended runtime and load testing

  • Eliminated recurring startup failures

  • Improved field reliability and commissioning performance

Hose Storage and Handling System - Manufacturing Process Improvement & Material Handling Design

While working at Ellicott Dredge Technologies, I designed and implemented a hydraulic hose storage and handling system intended to improve the safety, efficiency, and organization of hose fabrication operations within the manufacturing facility.

Large hydraulic hose spools used in production often weighed several hundred pounds and required significant manual handling during hose fabrication. The previous process was inefficient, difficult to manage safely, and lacked an accurate method for measuring hose lengths during production.

To improve the process, I designed a custom spool handling and storage system that integrated directly into the hose fabrication workflow. The system included a forklift-mounted spool holder that allowed large hose reels to be safely transported and hung on existing storage racks adjacent to the hose crimping station.

Once mounted, hose could be safely dispensed through a length counter and chop saw prior to crimping operations, significantly improving workflow efficiency and reducing manual handling requirements.

The project improved shop safety, reduced hose fabrication time, improved material handling ergonomics, and introduced automatic hose length measurement capabilities that were not previously part of the manufacturing process.

Major Highlights:

  • Designed a hydraulic hose storage and handling system for manufacturing operations

  • Developed a custom forklift-mounted spool handling attachment

  • Reduced manual handling of large hydraulic hose reels

  • Improved safety and ergonomics during hose fabrication

  • Integrated automatic hose length measurement into the production process

  • Improved workflow efficiency at the hose crimping station

  • Reduced hose fabrication time and material handling effort

  • Utilized existing shop storage infrastructure to minimize implementation cost
