What J. de Jonge does
J. de Jonge Group is a Dutch family-owned industrial services company founded in 1954 and now in its third generation of ownership, headquartered in Vlaardingen, Netherlands, with operational offices in Belgium, Germany, the United States, Saudi Arabia, and the United Arab Emirates, and a workforce of more than 650 FTEs. The company functions as an integrated EPC contractor, original equipment manufacturer, and maintenance service provider for mechanical and piping infrastructure, loading technology, storage tanks, heat exchangers, pumps, rotating equipment, and electrical & automation systems serving the oil and gas, petrochemical, chemical, tank terminal, marine/port, and emerging energy-transition verticals. Its blue-chip customer base includes Vopak, Shell, LyondellBasell, SABIC, Dow, Aramco, Air Liquide, Evos, and Neste Oil, with documented project scale reaching hundreds of thousands of labor hours per engagement.
The company's product and technology portfolio is anchored by proprietary loading arm series (EcoPro, Hydrotec, CryoTec, GasTec, and the LH2-MLA for liquid hydrogen) manufactured under the JLA brand, the HLP pump portfolio (twin screw, centrifugal, eccentric screw, submerged, and three-spindle screw pumps) 100% manufactured in the Netherlands, a full range of shell-and-tube, spiral, kettle, air fin cooler, and pressure vessel heat exchangers under HES, and bundled storage tank engineering, construction, and jacking services through TankX. The portfolio is certified to ISO 14001, ISO 3834-2, ASME IX, API 610, API 676, CE (PED/ATEX), SIL, OCIMF '99, EN 1474, and CO2 Performance Ladder Level 3, with Saudi Aramco vendor approval for the Saudi Arabian entity.
Revenue mechanics span four streams: (1) one-off EPC project contracts for large-scale mechanical, piping, loading, and tank projects typically tendered competitively with major operators, (2) recurring maintenance and service contracts on installed equipment with 24/7 support, (3) hardware sales of proprietary loading arms, pumps, heat exchangers, and related industrial equipment manufactured in-house, and (4) professional engineering and specialized industrial labor services. Pricing is project-based and quote-driven; distribution is direct enterprise sales with no third-party channel intermediaries. The 2024 acquisitions of Holland Legacy Pump Group and Progresso Group, the 2024 launch of the LH2-MLA, the 2025 Saudi Aramco approval, and the 2026 Koggehaven headquarters construction together indicate active inorganic and organic expansion under sustained family ownership.

J. de Jonge competitors and assessment
Company assessmentDirect peers
- Kanon Loading Equipment: Dutch manufacturer of marine and truck loading arms, gangways, and access equipment for the oil & gas, chemical, and food industries. Directly competes with JLA on marine loading arms and shares the Dutch industrial services heritage and customer base.
- Bilfinger: European industrial services provider offering mechanical, piping, and EPC services to process industries; already a documented partner with HLP on a chemical terminal project. Comparable to J. de Jonge's mechanical & piping and EPC contracting business across similar end markets.
- Smit Lamnalco: Dutch-headquartered marine terminal services provider operating loading arms, jetty operations, and ship-to-ship transfer services for oil, gas, and chemical terminals. Comparable to J. de Jonge's JLS/JLA loading technology and jetty service offering, with overlap in tank terminal and LNG bunkering markets.
- Allweiler (CIRCOR International): German-founded manufacturer of screw pumps, centrifugal pumps, and propeller pumps serving marine, oil & gas, and chemical markets. Highly comparable to J. de Jonge's HLP pump portfolio, with overlapping product technologies and end-market focus.
- Woodfield Systems: UK-based specialist manufacturer of marine loading arms, hose towers, and cryogenic loading systems for oil, gas, LNG, and petrochemical terminals. Directly comparable to J. de Jonge's JLA loading arm business across similar products, customers, and applications.
- Bauer Loading Systems: German manufacturer of marine loading arms and loading technology with strong presence in European petrochemical and tank terminal markets. Comparable to J. de Jonge's Hydrotec, CryoTec, and EcoPro series in product scope, customer profile, and regional competitive overlap.
Broad incumbents
- Sulzer: Swiss global provider of pumping solutions and rotating equipment services for oil & gas, petrochemical, and power markets. Directly comparable to HLP (pumps) and JRS (rotating services), but at much larger scale and with a broader product portfolio.
- Stork Technical Services (Fluor): Dutch-rooted industrial services and mechanical & piping contractor (now part of Fluor) serving oil & gas, petrochemical, and power customers. Comparable to J. de Jonge's mechanical & piping and turnaround services divisions across the same European client base.
- Kelvion (formerly GEA Heat Exchangers): German-headquartered global manufacturer of shell-and-tube, plate, and air-cooled heat exchangers for petrochemical, oil & gas, and power applications. Directly comparable to J. de Jonge's HES division on heat exchanger products, though Kelvion serves a wider industrial customer portfolio.
- Alfa Laval: Swedish global leader in heat transfer, separation, and fluid handling, including brazed plate, gasketed plate, and shell-and-tube heat exchangers. Overlaps with J. de Jonge's HES division on heat exchangers, though Alfa Laval serves a much broader industrial customer base.
