TSI has successfully implemented in Repsol the latest vibrometer / Meggitt technology in vibration monitoring for rotating machinery. The key of the project has been to incorporate the signals of existing sensors to the new monitoring system and its replacement with the minimum impact to the previous monitoring system manufacturer by Data Manager 2000 Bently Nevada / GE.

TSI has been implemented in Repsol Puertollano Plant an on-line vibration monitoring system in rotary compressors. This system is the latest Imagen4technology developed by the manufacturer vibrometer / Meggitt. This system aims to provide the appropriate monitoring and diagnosis functions, that are essential in this type of machines.

The key of the project has been to incorporate the signals from the existing sensors in the units to the new system of monitoring and the replacement with the minimum possible impact to the previous system, manufacturer by Data Manager 2000 Bently Nevada / GE. This actions has allowed our customer a significant cost savings and to carry out the implementation project in a short time.

The technology selected by Repsol based on VM600 architecture, consists on a centralizeImagen3d system with processing cards that has sixteen dynamics input channels each one and a data processing software system called Vibrosight®.

Vibrosight® is a software that enables data storage and processing such as: trends, frequency spectra, waveforms, orbits, waterfall … and a complete analysis for incorporating transient processing operation: Bode plots, waterfall, polar diagram and centre line.

Although Vibrosight® is a new technology recently launched to market it has important references and customers in addition to Repsol, customers such as Siemens, Ansaldo, Statoil.

New Wilcoxon´s machinerymate monitoring kits.

Wilcoxon is a Meggitt group company represented in Spain by TSI – Técnicas y Servicios de Ingeniería. Wilcoxon has just launched to the market two new portable vibration collectors MAC200 and MAC800.

MAC200 is a basic and practical handle equipment easy to use. It helps to detect incipient failures on machinery, increasing the productivity of without making unplanned stops. This equipment has a very low cost of acquisition and maintenance. The analyser has configurable alarms and can Imagen1measure BDU parameter that indicates the damage of the indicative It also has colour display which can set the alarm levels to view the status of the machine graphically.

On the other hand, the MAC 800 shares the same features as above one but with some improvements. This equipment has DATAMATE software that allows data storage for later analysis. It has a resolution of 800 lines and a dynamic range of 96 dBA.

The MAC800 has two additional functions: the possibility to hear the noise caused by defects in bearings through headphones and also incorporates a strobe light to measure the speed of the machine.

The application of this equipment is mainly in the industrial sector (paper mills, power generation plants, ships …) but they can be used for vibration measurements at any type of machine

Both data collectors are supplied with an accelerometer and the necessary accessories for initiating the action from day one.

Sener awards TSI the dynamic & acoustic design of a 1200 passenger ferry.

Sener awards TSI the dynamic & acoustic design of a 1200 passenger ferry.

Within the framework of collaboration that TSI, a specialized company in the dynamic and acoustic design of vessels, has with different national and international companies, and SENER as a leader in the field of shipbuilding engineering it has awarded TSI the Noise and Vibration Predictions for a 1200 passenger ferry, the basic engineering and detailed project is being developed by SENER.

These simulation studies: Vibration and Noise Prediction calculations aim to define in the early stages of the project the structural modifications and Imagen2the specific acoustic insulation required to ensure the compliance with the noise and vibration limits required by the Specification.

For the vibration prediction calculation a 3D Finite Element model that incorporates all the mass and stiffness characteristics of the ship is developed. From this model the expected vibration levels at the different locations of the ship are calculated. The comparison between these values and the limits, allow defining the structural modifications to ensure the compliance of the limits.

Similarly, in the case of noise prediction calculation a SEA- Analysis- Statistical Energy model, with all different sound sources and original isolates is carried out to obtain the expected noise levels in all the compartments of the vessel: passenger spaces, crew, labour and machinery. The comparison between these values and the limits define in the Specification for each local, allow defining the additional insulation to ensure the compliance of the limits stablished. Compliance, in both cases: vibration and noise values, are verified with corresponding sea trials.

TSI gives a seminar for the Spanish Navy of Noise and Vibration for comfort, “Acoustic Signature” and CBM – Conditioned Based Maintenance”

During January 2014, JAL- Jefatura de Apoyo Logístico- headquarters, it has taken place Seminar regarding vibrations and noise on board ships, acoustic signature “and CBM- Condition Based Maintenance, aimed managers, officers, and civilian personnel of the Spanish Navy. Imagen1The seminar has been also attended by NAVANTIA´s technicians.

The objective was to familiarize with these concepts in order to introduce these aspects in the Contractual Specifications.

There was a monograph focused on CBM Condition Based Maintenance. Methodology that is aimed to reduce the cost of operation and maintenance and increased availability of the vessels

After a review of the bases of this methodology and the tools for its development, practical aspects for its establishment were also analysed. Finally, as evidence of the Spanish Navy in the implementation of CBM, the CESADAR- Monitoring Centre and Data Analysis Navy work was pointed out.

The seminar was taught by Mr. Beltran, naval engineer with over 38 years of experience solving vibration and noise in all types of facilities.

At the end of the seminar, a Clients´ Satisfaction Index fill out by the attendants, the obtained indicator was 8.34 points out of 10.
