Back to school soon – for everyone!
From design through to build, commissioning and troubleshooting, VibraTec provides practical consultancy and control methods for controlling noise and vibration for marine vessels. Our services provide solutions to meet all necessary classification and regulatory requirements.
Ship design assistance
Vibratec has extensive experience in solving noise and vibration issues acquired over the last 30 years. This success is based on our highly skilled and experienced people and on established, proven, efficient methodologies.
Internal & external Noise and Vibration levels, as well as radiated noise levels, are measured during sea trials to confirm that project specifications are met and that new-build, re-build or conversion projects and equipment performs within expected parameters.
Underwater noise impact
Underwater noise from human activities is known to have varying adverse effects on marine fauna, depending on species. Vibratec has developed tools to measure and predict these man-made noise levels generated by the diverse types of noise source present in our oceans, seas, and estuaries, and the effect they have on marine species.
Troubleshooting – Solving operational problems
Degradation of machinery, damage acquired during vessel operation or environmental fouling can result in increased vessel noise & vibration or reduction in performance. Vibratec have the experience and capability to get to the heart of the problem and provide the practical solutions that can bring the vessel back into compliance.
VibraTec is able to provide consultancy services to create specifications for products and equipment, determining performance criteria, prioritizing development and writing specifications.
Our aim is to provide criteria and development procedures to match our clients’ needs, to reduce time and to give confidence in meeting development requirements.
Vibratec provides support for:
Defining indicators and critical levels of vibration and acoustics,
Determining operational loads from dedicated tests or from our extensive database of actual measured data,
Developing compliance procedures and test adjustments to avoid over-specification.
VibraTec guarantees a specification of your equipment that is consistent with its real loading, while complying with your constraints of quality (standards) and cost.
Following the evolution of standards, products often need updates to comply with new legislative requirements.
VibraTec can provide ongoing improvement of equipment NVH and mechanical reliability, within the frame of directives and standards such as 2000/14/CE directive, MIL-STD-810, DO160 and other ISO standards.
VibraTec is able to specify requirements regarding mechanical strength, workers’ health exposure, sound power, noise emissions etc.
Severe dynamic excitation of equipment should be taken into account during the specification stage of product development:
- For dynamic loads throughout the product life cycle: transportation, operating conditions, shocks and risk events & product operating environment.
- Definition of a realistic development plan accounting for increased excitation levels (PSD or SRS, accelerated testing).
Controlling loads during the conception stage realizes a design in accordance with the actual excitation, thus improving reliability. Unrealistic load levels lead to either under-specification or over-specification, resulting in additional cost in conception, production and/or maintenance.
Accelerated testing can validate the mechanical strength of the product. The robustness of the design can be validated either by modeling or testing.
During the conception stage, VibraTec is able to support the selection of relevant simulation strategies, thus strengthening the validity of the model and optimizing the design.
VibraTec’s expansive range of modeling capabilities makes it possible to:
Characterize operational loads;
Optimize product architecture taking into account relevant mechanisms (mass, stiffness, damping, viscosity);
Predict and quantify the dynamic, acoustic and mechanical response of systems;
Setup virtual prototypes by validating models through experimental fitting procedures;
Define optimization procedures and equipment sensitivity analyses;
Develop specific tools and methods.
By providing a complete modeling suite, Vibratec can strengthen model accuracy, minimizing the prototype testing phase and resulting in an optimized product which meets the necessary requirements without any surprises or additional costs.
VibraTec has setup a global and optimized suite of modeling tools in order to guarantee product reliability. Simulations enable risk anticipation, robustness and design optimization.
Finite Element Models cover a wide range of analyses, from solid dynamics to kinematics and acoustics. Simulations can handle linear behavior or complex non-linear responses, as well as multi-physics and multi-body interactions. Virtual prototypes and multi-criteria optimization can then be undertaken.
Using extensive expertise, validated calculation procedures, robust tools and digital analyses tailored to the clients’ needs ensures the correct outcome in the most efficient, cost-effective manner.
While the experimental qualification of products requires building prototypes and therefore advanced design and important testing costs, simulation enables quicker testing of virtual prototypes without additional costs.
Correlating skills in measurement and computation, Vibratec develops numerical models validated with experimental testing and subsequently performs numerical testing including the effect of realistic loads.
Virtual prototypes reinforce the product conception by multiplying optimized solutions with multiple criteria whilst simultaneously reducing costs.
Risk monitoring is crucial to ensure production rates are maintained. VibraTec is able to provide support to:
Design methodologies for noise and vibration monitoring
Instrumenting pipelines, equipment and structures
Monitoring systems and methodologies require a good knowledge of the systems and both likely and possible risks. Through diagnosis, Vibratec is able to identify processes that are at risk and potential causes of problems or failure. By developing cooperative partnerships with production and maintenance teams, Vibratec is able to find the right tools and methods to meet system needs. Ranging from a single monitoring accelerometer to an entire control system, Vibratec is able to provide support in the implementation of solutions and controls that are most effective and cost efficient, ensuring ongoing production is achievable.
