What Hannon Hydraulics does

Hannon Hydraulics, LLC is a privately held, Irving, Texas-based custom hydraulic equipment manufacturer and remanufacturer founded in 1976, with an additional operations facility in Houston. The company designs, fabricates, repairs, remanufactures, and recertifies large-scale hydraulic systems — primarily hydraulic cylinders up to 50 feet long and 104 inches in diameter, hydraulic power units (HPUs) up to 1,400 hp, subsea accumulator assemblies rated to 7,500 psi, motion compensation systems (DSC/CMC), primary and secondary tensioning systems, marine riser and guideline tensioners, cantilever lift and roll boxes rated to 4,000 tons and 10,000 psi, and riser lifting tools. Equipment is engineered to ASME Section VIII Division 2, ABS, DNV, API, and ISO standards and includes explosion-proof HPU configurations for hazardous areas.

Hannon generates revenue across six streams: custom equipment manufacturing, repair and remanufacturing services, spare parts and aftermarket components, a no-downtime hydraulic cylinder exchange program (time-and-materials invoicing, no core charges, one-year unlimited-hours warranty), global field services (removal, installation, commissioning, inspection, reverse engineering), and recertification services for compliance documentation. Pricing is quote-based on every custom engagement; the go-to-market is relationship-driven enterprise field sales with 24/7 phone coverage and worldwide technician deployment. The company sells into four primary verticals — oil and gas drilling (offshore and land), mining, steel mills, and aerospace and defense — plus a long tail of specialty applications including construction, marine, power generation, amusement, and rail.

The customer base is project-based and enterprise, with documented engagements spanning a 100-mph roller coaster launch system, a Los Angeles subway tunnel boring machine rebuild (Mitsubishi and Hitachi), Mississippi riverboat hydraulic ramps, Harris scrap shear repair (saving $688,673 in replacement cost), and Sumitoma bauxite unloader cylinder rebuilds completed in days. Industry association memberships (NFPA, IADC, PESA) and classification partnerships (DNV GL, ABS, ASTM) anchor its credibility in heavy industrial end markets, while long-tenured craftsmen — including machinists with 20+ year tenures — form the operational backbone of the remanufacturing and field service businesses.

Direct peers

• Hydac: Manufacturer of hydraulic cylinders, accumulators (bladder, piston, diaphragm), HPUs, filters and fluid conditioning components used in oil & gas, mining, steel and marine. Closely comparable to Hannon's subsea accumulator and HPU product lines and aftermarket service model.
• Bosch Rexroth: Global market leader in hydraulic cylinders, HPUs, accumulators, and motion control systems across industrial, mobile and offshore applications. Directly comparable to Hannon across the full hydraulic equipment portfolio, with much greater scale and a broader catalog.
• National Oilwell Varco (NOV): Major OEM of drilling rigs and offshore equipment including motion compensation systems, BOP handling equipment, riser tensioners and drilling fluid systems. Directly comparable to Hannon's oil & gas drilling product portfolio, but at significantly larger scale.
• Atos (hydraulics): Italian manufacturer of proportional and servo hydraulic valves, cylinders and systems used in industrial, mobile and marine applications. Comparable to Hannon's servo-actuated cylinders and proportional hydraulic work for industrial customers.
• Bucher Hydraulics: Manufacturer of custom hydraulic cylinders, power units and systems for mobile, industrial and offshore applications. Comparable to Hannon on custom cylinder manufacturing and HPU design for demanding environments.
• Trelleborg (Offshore & Engineering): Supplier of polymer and engineered solutions including marine/oil & gas tensioners, seals and load-handling systems. Overlaps with Hannon's marine riser and guideline tensioner product line and offshore drilling customer base.
• Moog Inc. Specialist in high-performance motion control, servo-actuated and proportional hydraulic systems used in industrial, aerospace and defense applications. Hannon even remanufactures Moog/Hydrolux valves for customers, underscoring product-line overlap in servo hydraulics.

Broad incumbents

• Parker Hannifin: Large industrial conglomerate whose Cylinder Division and hydraulic systems overlap directly with Hannon's cylinders, accumulators and HPUs. Operates at much greater scale globally and competes on standard product lines, while Hannon differentiates on custom/oversize work and repair.
• Eaton: Industrial broad-line manufacturer with a substantial hydraulics business serving agriculture, construction, mining and oil & gas. Comparable on HPUs, valves, cylinders and motion control but serves as a large incumbent rather than a custom specialist.

Emerging players

• Flodraulic Group: North American hydraulic repair, remanufacturing and distribution specialist serving mobile, industrial and oil & gas customers. Overlaps with Hannon's aftermarket repair/remanufacturing service motion and exchange-program concept, but at a smaller, more regionally focused scale.
