Drass Komms

Drass R&D department continue to provide new and innovative products for the diving world. The latest component developed by DRASS is the new communication system with a new helium speech unscrambler algorithm (DRASS KOMMS). It is a wired communications system, designed to comply with the highest standards of the offshore industry. The system is a modern design concept which provides the optimum performance and numerous improvements if compared to the current communication systems available:

  • Drass makes use of a fully-digital Helium Speech Unscrambler (HSU) with a superior unscrambling algorithm. Each inner communication box contains a depth sensor, meaning that each HSU is capable of setting the proper unscrambling algorithm for its actual depth in a way that is completely transparent for the operators at the consoles. Drass HSUs are integrated with a communication box, RTS-Telex devices (BOSCH Group), customized by Drass for hyperbaric use. The HSU is installed inside the hyperbaric environment (inner area). Such a solution is unique in the world of commercial diving and it technically improves the unscrambling performance by shifting the pitch of the voices directly from the chamber; it reduces the transmitted noise. Moreover, the allocation of dedicated unscramblers to each communication point increases the redundancy of the entire communication system. The external control console operator can eventually bypass the HSU.
  • The system uses a state of the art commercial communication matrix for ship installation. It provides a more reliable and cost effective system, compared to the small production / prototype hyperbaric communication systems currently available on the market. The specific maintenance for DRASS KOMMS is limited to the replacement of one model only of communication box. This makes the vessel almost entirely independent from the assistance of the OEM.
  • The outer area communication system is based on the same unit used for the diving system, so the outer area communications can be interfaced with the other units included into the diving system. This interface is very quick and after the re-configuration of the all units connected to the LAN network brings advantages to the captain when talking with the divers inside the chambers or with the supervisor in the Dive or Sat Room. This is very helpful during the coordination of a particular job in which it is necessary to put different groups of people into contact to coordinate the entire job.
  •  Drass communication system can be completely configured in terms of operability using the standard (and free) software provided by the Communication systems. The matrixes may be easily connected to the configuration PC via Ethernet, USB or serial link; the full physical customization of the system is ensured having the possibility to choose each specific component from a standard part list. If required, the whole system can be serviced remotely by Drass (this will require a remote connection to the vessel). It has the function “RealTime Online Configuration & Monitoring”, giving the opportunity to change the configuration of the matrix during normal activities, without any work stoppages. This is an advantage over the other commercial diving communication systems.
  •  Spare parts can be provided quickly thanks to it being the only type of communication unit model used inside the inner area and outer areas of the vessel. Moreover, the system can be delivered few weeks because the items are generally in stock. This is a huge advantage given that the standard delivery times for similar products on the market can be counted in months.
  • The time required for maintenance is reduced greatly thanks to quick connector fitted on the inner area comms box, and for these reasons no screwdrivers for electrical connections are necessary. This makes the replacement operation easily doable to the divers themselves.
  • Drass communication system can easily be integrated with Drass Multimedia System.

Usually redundant matrixes are assembled in the power supply and controller and have the hot-swap function. Finally one single brand/model of communication system can supply the vessel Intercom and the Diving Intercom, unifying them into a single network. The system is designed to connect up to thousands of links, mixing several different technologies at the same time: hardwired analog, wireless and several frequencies and modulation. Redundancy is provided as standard with dual power supply and dual controller, all hot swappabl

Communication System Internal Course

 (“The Magnificent 500”) is the title of a recently published report that appeared in “Corriere della Sera”, the highly regarded Italian economic newspaper. It references the top 500 companies in Italy that had a substantial improvement in turnover between 2010 and 2016. Drass Galeazzi, in an analysis and comparison of over 12,000 like companies, was placed 119th and found itself amongst the top quartile of the "Magnificent 500".

Drass Galeazzi is the main company of a Group that in only five years increased the total turnover by 200%, with an average improvement per year of 11.5 million Euros. Similar results have been achieved for the Group equity (consistent improvement per year of 10.3 million Euros) and Total assets (average improvement per year of 12.5 million Euros). But the real strength of Drass is the shareholder equity that in the last few years is constantly on 80%, together with a ROI index of about 30%. Financial indexes show a flexible corporate structure characterized by an ever greater solidity. These conditions are made possible thanks to high profits, which are always reinvested into the business. Drass also achieves this impressive result due to its high level of innovation and flexibility, thanks to its ability to design and produce internally through an accurate certified quality process.

Since 2011, Drass has arranged internal training courses for members of the Electrical Design Team; for each new member of the electrical engineering department a training course on how to use “IGE-XAO SEE Electrical Expert”, the software used to produce all electrical schematics of the Drass diving electrical system. A couple of sessions are arranged for each user; allowing the electrical designer/engineer to be able to produce all electrical drawings as per Drass standard engineering phases.
– the course detailed Pros to use this program, including some “tips and tricks” and basic “Do and Do not” on schematics.
All features of this electrical software are easy to use and are dedicated to electrical design:
o          IEEE/ IEC component libraries
o          Automatic numbering for components, cables and wires
o          Automatic generation of cables, terminals, components, etc.
o          Cross-references (available contacts, etc.)
For the electrical engineering department, all the eatures listed above are time and money-saving for the complete process of engineering on each project.

Inside the white chamber for pipes cleaning are completed all the qualitative analysis on the samples of the washed pipes. The container was built to complete different cleaning methods on oxygen and breathable gas systems as requested from the Offshore Standard DNV-OS-E402 SEC. 2 J302 and ASME G93-03.
The analysis consist of a measurement taken on the NVR “not volatile residue” and the VOC “volatile organic carbon” levels inside the liquid sample, earlier extracted from the gas lines flux.
By the integration of  pumps and recycling tanks it is possible to wash the pipes up to 2”-1/2 diameter through chemical solutions that attack the polluting agent. To keep the pipe washed will permit the destruction of hydrocarbons until it will return to the parameters requested by the above mentioned standards.
Depending on the  tubes final used, breathable gas or pure oxygen transportation, the samples are analyzed with two different process analysis.
Thanks to all this we were able to get a real analysis lab directly on board, during the installation and commissioning phases of a diving system.
