DRASS has been selected by a reputable manufacturer of SCUBA regulators as the facility to perform their annual product testing according to EN 250 standard.
Such tests are performed using DRASS’ recently manufactured Life Support Equipment Test Facility, capable of testing SCUBA, diving regulators, diving helmets and rebreathers according to applicable standards. DRASS performs a full range of tests including breathing performance up to 50 bar ambient pressure using air, nitrox or helium, both in gas or submerged, cold testing (2-4 °C) with humidification and heating of the breathing gas, carbon dioxide testing, noise testing, etc.
Thanks to the rotating capability of the test tank, vertical and horizontal tests of breathing apparatus can be performed during the same session without the need to vent and blow down the tank between tests.
At the end of January DRASS had the pleasure of welcoming the Mayor of Livorno, Mr. Luca Salvetti, for a site visit. This was an opportunity to meet DRASS staff, tour the company departments including the entire production facilities, and give a speech for the benefit of all staff. The mayor praised the technology and organisation of DRASS activities and was also impressed with DRASS’ green initiatives and graduate training programme. Mayor Salvetti promised support to overcome the actual logistical issues of the area surrounding DRASS, and he commended the significant number of young people working in complex, high technology roles within DRASS. We thank Mayor Salvetti once again for his visit and support.
Following the past few months of intense and effective hard work, Drass would like to express a huge thanks to Professor Paola Gualeni, Professor Diego Villa, and the DITEN Department at the University of Genoa for the internship collaboration which has proven to be a great achievement. Pietro Panizza and Emanuele Fassone, have finally graduated in Naval Architecture and Marine Engineering and we are very proud and happy to have been part of their success with the theses regarding the "Influence of morphological design choices for a Compact Submarine" and "Stability and trim Polygon Analysis for a Midget Submarine".
Following the invitation from the University of Pisa at the latest DII Talks (hosted by the Department of Information Engineering), DRASS held a seminar in which its developments in the fields of commercial diving and defence were presented to the entire second-year Telecommunication Engineering Postgraduates. The conference had a particular focus on technology applied for external communications and sonar processing on submarines. The general architecture and typical communication standards of exterior communication systems in civil and military field was described, including GMDSS system (Global Maritime Safety System), ALE3G (Automatic Link Establishment) and the use of SDR (Software-Defined Radio) for military communication.
In addition, the sonar processing architecture and its functionality of detection, tracking and analysis of tracks was discussed, going into detail on the techniques such as DEMON (Demodulation of Envelope Modulation On Noise) and LOFAR (Low-Frequency Analysis and Recording). In conclusion, DRASS gave an overview of the interaction between the sonar system and other systems in submarines such as CMS (Combat Management System) and WECDIS (Warship Electronic Chart Display & Information System).
We continue to honour our pledge to the environment by becoming greener each year!
We are doing this through the promotion and application of a very ambitious campaign entitled 'Environmental Footprint: DRASS Engagement', with various sub-projects currently in development. Through one such project, 'Plastic-Free', DRASS aims to significantly reduce the use of plastics and Co2 emissions. To this end, DRASS has installed additional water coolers throughout its communal areas, dispensing both still and sparkling water. In tandem with this, one of the DRASS Christmas gifts to each member of staff was an aluminium water flask.
This is one of many green initiatives, and we are pleased to see how it has been welcomed by one and all!
