Wallsystems

Stord Offshore as has developed and manufactured wallsystems since 1984. The systems includes explosion relief panels, panels for natural ventilation, blanking panels, corrugated panels and heatshield panels. Our wallsystems are to be found on several installations offshore.

Wall-installation (explosion relief panels/louvre and blanking panels) installed on Sleipner. A total of 3600 m2 of wall was manufatured and installed.

Heatshields Snorre A TLP (800 m2).

Including explosion-relief panels and louver panels, a total of 4.300 m2 was installed.
