About

HMH Holding Inc. (HMH) is an American provider of oil and gas drilling equipment and aftermarket services, headquartered in Houston, Texas. The company is best known for manufacturing critical pressure control and topside drilling systems for both offshore and onshore operations.

The company's business is divided into two primary equipment categories: pressure control systems and topside equipment. Its pressure control product line includes blowout preventers (BOPs) and their control systems, which are vital for well safety, alongside drilling risers and wellhead connectors. The topside equipment portfolio comprises hoisting and rotating machinery like top drives and iron roughnecks, as well as drilling circulating systems such as mud pumps and mixing equipment. HMH provides these comprehensive equipment packages for new drilling rigs or individual components for rig reactivation and upgrades.

HMH generates revenue by selling this equipment and offering extensive aftermarket services to a global customer base. Its clients include drilling contractors, oil and gas exploration and production companies, and capital equipment manufacturers like shipyards. The aftermarket services business involves the sale of replacement parts, equipment repair and recertification, and on-site field labor. Additionally, the company is developing integrated digital solutions aimed at remote drilling automation and condition-based monitoring for its installed base of equipment. HMH also extends its equipment and service offerings to the onshore and subsea mining industry.
