For many decades offshore rigs were envisioned by their engineers as fixed legged ships. Lots of steel were used to build these reasonably sized rigs. Thicker steel was the answer to protect walls against rust. After several grave accidents also fire resistant blankets were implemented.

As the rigs turned larger and more heavy, due to incorporation of field yield enhancing equipment on the platforms, the need for light weight but still safe walls arose. InterDam has recognized this demand and developed a full range of fully certified, light weight, easy to install architectural products under the name of G21. Safe. Simple. The products of the 21st century.

The current flagship is the G21 Fire Panel, a sandwich wall system, which is becoming rapidly recognized as the 4th Type. Originated from recent offshore wind HVDC transformer platforms, G21 Fire Panel is now available for the offshore oil and gas industry as a response to the continuous need to save weight and improve on safety.

To inform our clients and partners as fully as possible about the G21 Fire Panel, we have compiled a databook which includes all relevant technical documents supporting the G21 Fire Panel.
