Drass chooses Tungum for Subsea 7’s Seven Kestrel dive system

Drass Galeazzi, a world leader in the design, manufacture and installation of saturation diving systems, has utilised Tungum tubing again as part of its state-of-the-art diving system rated to 300m on board a new Subsea 7 dive support vessel.

2017 08 02 085107The Seven Kestrel is a 125-metre long dive support vessel designed by Subsea 7 in collaboration with Hyundai Heavy Industries Shipyard in Ulsan, South Korea and Wärtsilä Ship Design, Norway.

Drass provided the vessel with an 18-man, twin-bell saturation diving system, equipped with 10 independent locks, two large transfer under pressure compartments, 2 x 18 man hyperbaric lifeboats, all with the latest cutting-edge operational technology, certified by DNV GL.

Drass worked closely with Subsea 7 on the material specification for the system and more than 10,000 metres of Tungum tube was used in the installation for the following reasons:

  • Oxygen compatibility - endorsed by IMCA, D 012, ASTM G124-10
  • Corrosion resistance to sea water , especially in the splash zones
  • Tungum lasts for the life time of the vessel
  • Cost effective related to competitive alloys
  • Ease of installation
  • DNV approval
