TEWKESBURY, UK – Drass Galeazzi chose Tungum tubing for a 300-m (984-ft) water depth-rated dive system onboard Subsea 7’s dive support vessel Seven Kestrel.
Subsea 7 designed the 125-m (410-ft) long vessel with Hyundai Heavy Industries Shipyard in Ulsan, South Korea, andWärtsilä Ship Design in Norway.
Drass provided the 18-man, twin-bell saturation diving system, equipped with 10 independent locks, two large transfer-under-pressure compartments, and 2 x 18-man hyperbaric lifeboats, with the technology certified by DNV GL.
More than 10,000 m (32,808 ft) of Tungum tube was used in the installation due to a variety of factors, including:
- 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.
