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.

Completion job DSME

DRASS 700 series installation for the Korean Navy, in DSME yard, is near to its completion. The activities, performed in close cooperation with yard workmen, are proving to be a great success with this new surface supplied mixed gas diving system being delivered by the end of this summer. The diving system has the new DRASS automatic and fully integrated handling system (overall dimensions in closed position 5500x2800x2600) which is capable of deploying the Wet Bell up to 300 fsw (90 msw). The oil-free HP compressors, upstream of the on-line gas analysis system with a dedicated Gas Chromatographer, can produce 300bar breathable air for high quality diving operations. A three lock hyperbaric chamber allows the performance of operations with basket and wet bell at different depths with two different decompressions tables contemporarily.

100 Series Integration Course

From April 9th  to 12th  we had the pleasure of hosting the participants of the second edition of the course on the Integration of the Drass 100 Series Saturation Diving System with a DSV. The participants took part in the four-day intensive course, learning about the various Drass procedures, equipment and lessons learned through all these years in the business. They also had the opportunity to have some lessons in the workshop where a context could be given to certain procedures. Unfortunately some of our guests had to leave early, but those who remained were taken out for a delicious lunch followed by a tour of Pisa. We take the opportunity to thank all of those who took part, for their positive feedback and to the Companies that continue to place their trust in us.

Drass was awarded a contract by Hanjin Heavy Industries & Construction for the delivery of a 700 Series surface supplied mixed gas diving system, similar to the one completed and delivered in the summer of 2013.
The new Vessel will be built in South Korea at Hanjin Heavy Industries & Construction Shipyard for the Korean Navy.
The new 700 Series Diving System will be certified by Korean Register on the base of the consolidated design of the 1st ATS-II Vessel.
The System is capable for an operability up to 300 fsw(91m) and is going to be provided with a Triple Lock surface decompression chamber provided with a life support system and gas management; one man transportable chamber is supplied and installed on the same deck of the handling system to allow a quick ingress of the Divers into the Chamber.
Thanks to a very compact design, the handling system is fully integrated in the Vessel General Arrangment. It is controlled by PLC and provided with automatic, semiautomatic and manual launch and recovery procedures. The Launch and Recovery is operated from a Wet Bell Handling Control Console. In addition Diver Stage and basked are provided for Divers launch and recovery.
