United Bulk Terminal — Elevated Dock Office Support Structure Industry: Ports & Terminals  |  Service: Structural & Mechanical Engineering Location: United Bulk Terminal, Davant, LA The Challenge As part of United Bulk Terminal’s expansion program, the upper surge bin on the transfer tower was to be replaced with a new elevated dock office — a […]

Oxbow Sulfur Handling Facility — High-Angle Conveyor Engineering

Industry: Chemical / Industrial  |  Service: Conveyor Engineering & Analysis Location: Southampton, UK The Challenge Oxbow’s sulfur handling facility in Southampton converts liquid sulfur into pastilles using a steel belt system, then transfers the pastilles into a silo for truck loading. The site presented a set of interrelated engineering challenges: The site footprint was too […]

United Bulk Terminal — Transfer Magnet Monorail Engineering

Industry: Ports & Terminals  |  Service: Lift Planning & Rigging Engineering, Structural & Mechanical Engineering Location: United Bulk Terminal, Davant, LA — C1–C2–C6 Transfer Tower The Challenge As part of the terminal’s expansion to add a parallel C2 conveyor alongside the existing C1, United Bulk Terminal needed magnetic separators installed at the C1–C6 transfer to […]

United Bulk Terminal — Sky Hopper Support Structure Engineering

Industry: Ports & Terminals  |  Service: Structural & Mechanical Engineering Location: United Bulk Terminal, Davant, LA The Challenge As part of a terminal expansion at United Bulk Terminal, a new C2 conveyor was to be installed parallel to the existing C1 conveyor on the C1–C2–C6 transfer tower. The new conveyor required the addition of new […]

Jaw Crusher Support Stand Design — Metal Recycling Facility

Industry: Metal Recycling  |  Service: Structural & Mechanical Engineering The Challenge A metal recycling plant needed a support stand designed for a new jaw crusher on a very compressed timeline. The urgency was compounded by the fact that complete dimensional and load data from the equipment supplier were not available when the design needed to […]

Derailed Coal Stacker Recovery — Emergency Structural Engineering and Lift Planning

Industry: Energy & Power  |  Service: Lift Planning & Rigging Engineering, Structural & Mechanical Engineering The Challenge Extreme high winds swept through a power plant stockyard and propelled an unsecured coal stacker down its track, through the end stops, until it came to rest on a hillside. The stacker’s yard conveyor truss and drive house […]

Shawnee Fossil Plant — New Hopper Design for Conveyor BC-9

Industry: Energy & Power  |  Service: Structural & Mechanical Engineering, Conveyor Engineering & Analysis Location: Shawnee Fossil Plant, Paducah, KY The Challenge Shawnee Fossil Plant needed to replace the reciprocating feeders feeding Conveyor BC-9 with new vibratory feeders, and replace the existing rack-and-pinion gate with a heavier-duty unit. What began as a local reinforcement and […]

Water Clarifier Slewing Bearing Replacement — Structural Engineering Support

Industry: Energy & Power  |  Service: Structural & Mechanical Engineering The Challenge A power plant’s water clarification tank — essential to solids removal within the facility’s carbon capture system — required immediate maintenance. The slewing bearing at the center of the clarifier had failed due to water intrusion caused by rain exposure. Replacing it required […]

HRSG Harp Replacement Engineering — Heavy Lift Support System for Gas-Fired Power Plant

Industry: Energy & Power (Gas-Fired)  |  Service: Lift Planning & Rigging Engineering, Structural & Mechanical Engineering The Challenge HRSG units are designed for approximately 20 years of service life, during which the harp tubes are exposed to high temperatures and corrosive conditions that cause leaking and efficiency loss. At this gas-fired power plant, six large […]

Cogen Power Plant Monorail Design for HRSG Harp Replacement

Industry: Energy & Power (Cogeneration)  |  Service: Lift Planning & Rigging Engineering, Structural & Mechanical Engineering The Challenge A cogeneration power plant required the removal and replacement of heat recovery steam generator (HRSG) harps. The project presented two distinct challenges: first, the harps came in a variety of sizes and geometries, making a single-design monorail […]
