Haverly Systems

What Haverly Systems does

Haverly Systems, founded in 1962 by Larry Haverly in Denville, New Jersey, is a privately held software company that builds decision-support and optimization systems for the global energy and process industries. Its product suite centers on H/Planet (cloud-based enterprise planning and optimization) and GRTMPS G5 (desktop planning system), both built on the company's proprietary Generalized Successive Linear Programming (gSLP) algorithm, which combines adherent and distributive recursion to solve complex non-linear refinery planning models. Adjacent products include H/CAMS (crude assay management), H/COMET (cloud-based crude oil evaluation with API integration), H/Sched (operations scheduling), NetBlend (product blending), and PetroCalc (mobile petroleum calculator), supported by proprietary crude assay libraries from Chevron, Phillips 66, and Haverly.

The company targets major integrated energy companies and refiners, including named customers TotalEnergies, Suncor, Irving Oil, PetroRabigh, EGPC, CountryMark, and KBC, supported by regional offices in the US (NJ, CA), UK, Singapore, India, and Middle East/Africa, and by consulting partners 1898 & Co., iOG Solutions, QC2 Solutions, and Refining Advantage. Revenue derives from software licenses and cloud subscriptions (H/COMET, H/Planet, NetBlend), annual technical support agreements, training courses, and partner-led implementation services. Distribution is direct enterprise sales supplemented by a partner channel, with annual MUG and MUGI user conferences as the primary demand-generation and community events.

Recent organizational signals include the retirement and subsequent passing of Dr. Martin Fieldhouse (long-tenured Managing Director of Haverly Systems Europe) in 2026, the unexpected passing of long-time technical developer Dr. Richard Tan in April 2025, and new hires Snehil Gopalka (Principal Consultant, India) and Peter Colletti (Optimization Engineer, US West Coast) to sustain delivery capacity.

Revenue model

1. Software Licenses and Subscriptions: Haverly generates revenue primarily through software licensing and annual subscriptions. Products are offered in both cloud-based (H/Planet, H/COMET, NetBlend via annual subscription) and desktop PC-based (GRTMPS G5) deployment models. H/COMET is explicitly described as an 'Annual Subscription Optimization' platform. PetroCalc is available as a mobile app. Multi-user cloud deployments support interactive reporting and collaboration.
2. Technical Support Agreements: Clients with current support agreements gain access to the technical support website providing software updates, documentation, knowledge base articles, and presentations from previous conferences. Multiple product-specific support email addresses exist ([email protected], [email protected], [email protected], [email protected], [email protected], [email protected], [email protected]).
3. Training and Education: Courses for various products are available throughout the year at various locations. Experienced consultants provide in-depth instruction reinforced with hands-on assignments. Training covers both novice and expert levels. Courses are taught at Haverly locations and can be delivered at client sites with standard or custom curriculum. Course durations range from 1 day to 4 days depending on product and depth.
4. Consulting and Implementation Services: Haverly partners (iOG Solutions, Refining Advantage, QC2 Solutions, 1898 & Co.) provide consulting and implementation services for Haverly software deployments. These partners have skills on H/CAMS, GRTMPS, and H/Sched and offer domain expertise in supply chain management, LP strategies, and refinery optimization.

Core offering

Haverly Systems develops and licenses enterprise decision-support software for the energy and process industries, centered on linear programming-based refinery planning and optimization. Its product suite includes H/Planet and GRTMPS for planning and optimization, H/CAMS for crude assay management, H/COMET for cloud-based crude oil evaluation, H/Sched for operations scheduling, NetBlend for product blending, and PetroCalc as a mobile petroleum property calculator. The company also distributes commercial crude assay libraries and provides training and consulting services through its global offices and partner network.

Product overview

Haverly Systems provides a suite of enterprise decision support software for the energy and process industries. The portfolio centers on H/Planet (cloud-based planning and optimization) and GRTMPS (desktop planning system), both offering non-linear optimization capabilities for refinery planning. These core platforms are complemented by H/CAMS (crude assay management), H/COMET (cloud-based crude evaluation), H/Sched (operations scheduling), and NetBlend (product blending). PetroCalc provides a mobile calculator app, and the company offers commercial crude assay libraries from Chevron, Phillips 66, and its own collection. The products use gSLP optimization algorithms, support multi-location and multi-period modeling, and integrate with external process simulators via PSI interfaces.
