Van Cappellen Consultancy B.v.

What Van Cappellen Consultancy B.v. does

Van Cappellen Consultancy B.V. is a privately held Dutch engineering consultancy founded in 1984 by Willem van Cappellen and headquartered in Papendrecht, Netherlands. The firm provides specialist noise and vibration control services exclusively for the maritime sector, primarily luxury motor and sailing yachts ranging from 20 to 160 meters in length, with ancillary work for merchant vessels. The company has accumulated experience across more than 500 yacht projects over four decades and works with leading builders including Feadship, Royal Huisman, Southern Wind, Sunseeker International, Ocea, and Michael Schmidt Yachtbau, as well as with classification societies such as DNV, Lloyd's Register, and MCA.

The company's service portfolio spans the full project lifecycle: vibration analysis using Finite Element Methods (FEM), noise level predictions via proprietary empirical formula-based software developed in the 1990s and Statistical Energy Analysis (SEA) achieving 2-3 dB(A) accuracy, insulation treatment consulting (sound, fire, thermal), on-site inspections during construction, sea trial noise and vibration measurements, and transmission loss and damping loss factor testing in an in-house facility operating close to ISO 140-3 and 717-1 standards. The firm employs proprietary prediction tools integrated with VAOne commercial software and maintains a database of machinery foundation information calibrated against real-world measurements. In 2022, the company launched Brockx, a consumer product: a soundproof cabinet for air conditioners and heat pumps, alongside the creation of a new Product Design Engineer role.

Van Cappellen operates as a project-based professional services firm selling directly to yacht owners, shipyards, and other consultancy firms. Go-to-market relies on word-of-mouth referrals, direct enterprise relationships, a content-rich website with case studies, and organic social media. Pricing is bespoke per project scope with no public pricing disclosed. The company describes itself as a 'small but solid family business' and shows no evidence of external investors, public listing, or institutional ownership. Active recruitment signals as of the most recent data indicate ongoing headcount expansion.

Functional benefit

Products and services

• Vibration Analysis Structural vibration analysis using finite element methods (FEM) to study vessel behavior, calculate natural frequencies, input mobility, and 6-DOF calculations for machinery foundations and support structures.
• Insulation Treatments Sound, fire, and thermal insulation consulting for yachts, including insulation space requirement planning, structural fire protection plans, and material weight calculations. Treatments cover damping, bulkheads, floors, sides, overheads and partitions.
• Noise Level Predictions Noise level calculations using either empirical formula-based software or Statistical Energy Analysis (SEA) to verify contractual noise values, simulate yacht noise and vibration environments during design, and predict levels within 2-3 dB(A) accuracy.
• On-Site Inspection Quality control and validation services including inspection of insulation treatment installation, machinery equipment installation validation, and intermediate measurements such as mobility and natural frequency measurements.
• Noise and Vibration Measurements Comprehensive noise and vibration measurements using handheld equipment, including standardized sea trial measurements, troubleshooting, and structural vibration measurements during the build process.
• Transmission Loss and Damping Loss Factor Testing Materials testing in the firm's test facility for Damping Loss Factor (DLF) and Sound Transmission Loss (TL) of partitions, using sound pressure and sound intensity measurement techniques following ISO standards (140-3, 717-1).
• Other Consultancy Services Additional consultancy services including writing noise and vibration specifications for new builds or refits, providing second opinions on vibro-acoustic cases, hands-on advisory for smaller shipyards, seminars on noise and vibration awareness, and independent product reviews for material suppliers.
• Brockx A cabinet designed to reduce noise from air conditioners and heat pumps, developed in response to new laws and regulations to reduce noise from these devices. The product is designed for consumer residential use, featuring soundproof materials and ensuring adequate air supply for the appliance.

Broad incumbents

• DNV: Classification and assurance provider offering noise and vibration advisory services for maritime clients, including superyachts. Competes on class-approved NVH guidance for shipyards that are Van Cappellen customers.
• Bureau Veritas: International classification society providing marine advisory, survey, and rule-based noise/vibration compliance services across ship and yacht new-builds. Wider portfolio but competes for the same compliance-driven advisory scope.
• Lloyd's Register: Global classification society offering broader marine advisory including noise and vibration rule compliance and shipbuilding support. Overlaps with Van Cappellen via class approval and noise specification work for clients.

Others

• TNO (Netherlands Organisation for Applied Scientific Research): Dutch applied research organization with maritime acoustics and structural dynamics capabilities. Provides enabling research and measurement expertise relevant to yacht NVH but does not compete as a boutique consultancy.
• MARIN (Maritime Research Institute Netherlands): Dutch maritime hydrodynamic and ship research institute where Van Cappellen's founder Willem previously worked as lead engineer. Adjacent research organization that supplies hydroacoustic and structural knowledge feeding the marine NVH ecosystem.

Emerging players

• Gamba Acoustique: Independent French acoustics consultancy active in transport and industrial noise/vibration including marine applications. Smaller specialist competitor pursuing similar boutique NVH engagements in the European yacht market.
• Signal Group: UK-based noise and vibration consultancy serving transport and industrial clients including maritime applications. Smaller, growing competitor pursuing similar measurement, prediction, and compliance work.

Regional players

• CETIM (Centre Technique des Industries Mécaniques): French technical centre providing mechanical engineering services including vibration analysis and noise testing for industrial and marine clients. Regional competitor offering comparable measurement and analysis services in France.

Direct peers

• Müller-BBM: German acoustics and vibration engineering consultancy with an established maritime practice providing NVH services for ships and luxury yachts. Most directly comparable specialist competitor to Van Cappellen in yacht structural acoustics.
• Wolfson Unit (University of Southampton): University-based maritime acoustics research and consultancy group providing noise and vibration engineering services to the shipbuilding and offshore sectors. Closely aligned specialist NVH provider for vessel design.
