Hydratight Ltd.

What Hydratight Ltd. does

Hydratight Ltd. is a UK-based specialist provider of on-site mechanical services and joint integrity solutions for high-risk, mission-critical energy and industrial facilities. Founded in 1990 and headquartered in Darlaston, United Kingdom, the company deploys portable precision machining equipment, controlled bolting technology, and live-system repair solutions to customer sites worldwide. Core service lines include controlled bolting (precision torque, hydraulic tensioning, flange alignment), on-site machining (CNC drilling/tapping via geniSYS, EDM, flange facing, line boring, milling), online services (hot bolting, hot/cold tapping, pipe freezing, composite wrapping), process services (chemical cleaning, lube oil flushing, weld testing), and pipeline services (commissioning, hydrostatic testing). The company also offers tool rentals and training.

Hydratight's technology platform is anchored by proprietary systems including the MorSafe™ clamp restraint system (designed for hot bolting on live piping with ASME-compliant clamps tested to 1.5× design pressure) and the MorSeal™ flange enclosure clamp (subsea leak repair with dual sealing system). Technology domains span hydraulic tensioning, pipe freezing with liquid nitrogen, hot/cold tapping, on-site CNC machining, composite wrapping, and subsea leak sealing, all independently certified by DNV GL, Lloyd's, and TÜV. The company employs 501-1,000 staff and operates under Enerpac Tool Group Corp. (NYSE: EPAC), leveraging the parent's distribution network across more than 25 countries.

Revenue is generated through project-based professional services contracts, equipment rentals, and training, with quote-based pricing determined by project scope, complexity, location, and mobilization requirements. Multi-year contracts with enterprise customers in oil & gas, power generation, petrochemicals, nuclear, and shipbuilding form the core revenue base. The go-to-market motion is exclusively direct enterprise field sales, with specialist technicians and engineers deployed to customer sites. Notable enterprise customers documented in case studies include Petroleum Development Oman (PDO), Total E&P Congo, Groupement Berkine, APO (Tunisia), and major North Sea and North American operators, with engagements spanning offshore platforms, refineries, solar thermal facilities, and nuclear plants.
