What Goltens does

Goltens is a privately held global independent service provider specializing in on-site machining, diesel engine repair and maintenance, and green technology retrofits for marine and industrial assets. Founded around 1940 and headquartered in Austin, Texas, the company operates 28 service locations across 15 countries with over 1,000 employees, serving ship-owners, OEMs, shipyards, offshore drilling operators, power generation plants (including nuclear and hydro), and industrial customers. Its core technical capabilities include in-place crankshaft machining, line boring, metal stitching, laser alignment, electronic engine control service (Woodward and Heinzmann distribution), and 3D scanning-based execution of ballast water treatment, scrubber, and EEXI compliance retrofits.

The company's revenue model combines professional services (planned maintenance agreements, emergency repair contracts, and turnkey retrofit projects) with hardware distribution (engine controls, spare parts, chocking compounds, emissions monitoring systems, filtration, and partner products). Pricing is quote-based and not publicly disclosed, with services delivered through direct field service teams in 28 offices and through authorized distributor and regional agent channels in smaller markets. The company is organized by region (Americas; Asia; Europe, Middle East and Africa) plus specialized divisions including Goltens Green Technologies and Woodward Controls, and holds ISO 9001/14001/45001 and Germanischer Lloyd certifications across multiple entities.

Goltens pursues a partnership-led growth strategy, layering technology alliances (IPCO Power fuel homogenization, Orcan Energy and Climeon ORC waste heat recovery, WE Tech Solutions) and distribution agreements (BOLL Filter Corporation) on top of its core service franchise. Notable recent moves include the 2025 establishment of the Batam hub near Singapore, contribution to the Captain Arctic near-zero emission vessel launched in Dubai in November 2025, and the 2026 BOLL Filter distribution agreement covering the Americas. The legal entity, Goltens Worldwide Management Corporation, is privately held with no disclosed outside investors or public listing.
