What CIMAC does

CIMAC e.V. is a Frankfurt-headquartered non-profit association founded in 1950 that operates as the leading global technical forum for piston engines, gas turbines, propulsion systems, and power generation across maritime, rail, and stationary applications. Its core platform consists of 11 active working groups (WG2 Classification through WG22 Radiated Noise) and two strategy groups (Greenhouse Gas, Digitalization), producing CIMAC Recommendations, position papers, and guidelines that influence International Maritime Organization (IMO) policy and IACS classification rules. CIMAC also runs the biennial CIMAC Congress, the CIMAC Circle forum, CASCADES, web-seminars, tech-talks, and a members-only Technical Database of publications.

CIMAC's business model is membership-based: National Member Associations and Corporate Members across America, Asia, and Europe pay dues for access to working groups, publications, and standards-influence channels such as CIMAC@IMO. Revenue is supplemented by congress and event fees, though neither dues nor financials are publicly disclosed. The association serves four primary customer segments: engine and equipment manufacturers, ship owners and operators, classification societies, and research institutes/technical consultants, with secondary outreach to inland waterway industry participants in developing markets. Leadership consists of President Rick Boom and Secretary General Peter Müller-Baum, supported by a 51-100 employee Central Secretariat in Frankfurt.

The organization's competitive position rests on its regulatory access (direct IMO and IACS engagement), its cross-continental member ecosystem that represents the absolute majority of azimuthing propulsion manufacturers, and 75 years of accumulated technical publications. Recent strategic activity has focused on extending scope into digitalization (WG20 Digital Twins), underwater radiated noise (WG22 launched April 2025), and crew-digital interaction themes, alongside event presence at SMM 2026 and Posidonia 2026.

Core offering

CIMAC is a non-profit international association that facilitates technical interchange and consensus-based standardization for large-bore piston engines, turbochargers, and propulsion systems used in marine, locomotive, and power-generation applications. It organizes Working Groups and Strategy Groups covering classification, fuels, emissions, digitalization, system integration, and safety, and distributes the resulting Recommendations, CASCADES publications, Technical Database, and event programming (Congress, Circle, Web-Seminars, Tech-Talks) to its members.

Product overview

CIMAC is a leading global non-profit association promoting the development of ship propulsion, train drive, and power generation. The organization operates through a platform of technical Working Groups (WG2-WG22) addressing specific domains such as classification, fuels, exhaust emissions, propulsion systems, and digitalization. Strategy Groups on Greenhouse Gas and Digitalization drive industry transformation. The portfolio includes flagship events (CIMAC Congress, CASCADES, CIMAC Circle, Web-Seminars, Tech-Talks), a Technical Database of publications and recommendations, all focused on technical interchange among industry stakeholders including engine manufacturers, classification societies, research institutes, and operators.

Others

• DNV: DNV is a leading classification society and active CIMAC Corporate Member that develops its own maritime and energy rules. Its dual role as both rulemaking competitor and CIMAC participant captures the boundary between CIMAC's neutral convener function and members' independent standard-setting.
• Wärtsilä: Wärtsilä is one of the world's largest manufacturers of marine engines and an active CIMAC Corporate Member and working-group participant. As a customer/stakeholder rather than peer, it exemplifies the OEM membership base that CIMAC's value proposition is designed to serve.
• Bureau Veritas Marine & Offshore: Bureau Veritas is a major classification society and CIMAC member that independently develops maritime rules, standards, and verification services. It is both a CIMAC collaborator (via WG2) and a parallel rulemaker, illustrating the dual customer-and-peer nature of classification societies in CIMAC's ecosystem.

Direct peers

• SAE International: SAE International is a long-established global non-profit association developing engineering standards across aerospace, automotive, and commercial vehicles. It parallels CIMAC's business model of convening industry members to produce consensus technical standards, recommendations, and conferences, though focused on different industry verticals.
• ASTM International: ASTM International is a global standards development organization that convenes members to produce consensus technical documents across industries. It mirrors CIMAC's operating model of voluntary technical committees, member-driven standards, and committee publications, but at much broader industrial scope.
• IACS (International Association of Classification Societies): IACS is the global non-profit association of classification societies that formally collaborates with CIMAC through the WG2 Classification working group. Both are non-profit associations developing consensus technical rules for the maritime sector with overlapping member ecosystems and a similar convener-driven standards model.
• ASME (American Society of Mechanical Engineers): ASME is a major non-profit professional association and standards body for mechanical engineering. It overlaps with CIMAC's propulsion and power generation subject matter at a broader mechanical engineering scale, producing codes, standards, and conferences that compete for similar member attention and dues.

Broad incumbents

• ISO (International Organization for Standardization): ISO is the world's largest international standards body, with technical committees (e.g., TC 70 on internal combustion engines, TC 8 on ships) that overlap with CIMAC's scope. It represents a broader incumbent in the same standards-development category, with a wider but shallower industrial footprint than CIMAC.
