Work in early project phases includes defining noise and vibration criteria for crew and passengers based on IMO guidelines and classification society frameworks. The work includes drafting and negotiating building specifications between shipowner and yard, clarifying requirement levels and how these influence mitigation measures and project decisions, and supporting alignment of owner expectations.

Ship Noise and Vibration Services for Design Build and Operation
Resolve ship noise and vibration challenges to improve onboard comfort, reduce risk and support better decisions for yards, owners, operators and designers
Ship noise and vibration influence crew working conditions and passenger comfort, with requirements varying by vessel type and use. The service supports shipowners, shipyards and suppliers in defining comfort criteria, preparing building specifications and aligning expectations early in projects.
Ship noise and vibration consultancy across the vessel lifecycle
The work includes analysis, predictive calculations and measurements of noise and vibrations before, during and after construction. Activities cover design evaluation, structural and insulation testing both in the laboratory and on-site, measurements during harbour and sea acceptance. Noise measurements can be performed under authorisation from the Danish Maritime Authority and delivered as accredited results or guiding information.
Challenges
When ship noise and vibration are not considered sufficiently through-out the project, unresolved issues can delay the construction process.
Unclear comfort criteria delay early decisions
If noise and vibration criteria are not defined early, there may be no clear basis for further design decisions. This can make it difficult to align expectations for crew areas and passenger comfort before construction.
Design decisions are made without an acoustic basis
When drawings, machinery layouts or structural solutions are not evaluated against requirements, the acoustic consequences of design choices may remain unclear. This can make later changes more complex.
Acceptance tests reveal unresolved conditions
If measurements, protocols and follow-up are not prepared before acceptance, deviations may only become visible late in the project. This can delay clarification of whether the agreed conditions are met.
Operational noise and vibration issues can be difficult to isolate
Without focused troubleshooting, the underlying source of adverse noise or vibration may remain unclear
Benefits
Use documented acoustic data to evaluate ship noise and vibration conditions.
Align and document specification agreements
Documented input on noise and vibration criteria supports specification work and negotiation between shipowner and yard. This provides a basis for evaluating whether agreed specifications reflect intended comfort levels and supports alignment and safeguarding of owner expectations.
