MARRS Offshore handrail in use on the BP Clair Ridge platform in the North Sea

MARRS Offshore Handrail

With added fire-safety features, this patented handrail system meets the durability and strength demands of offshore installations.

  • Description Description
  • Resources Resources

MARRS® (Multi-Angle Rapid Railing Systems) Offshore is a unique, patented handrail system designed and developed in-house to meet the required strength, durability, fire-reaction performance, and safety properties required in offshore oil and gas installations, including NORSOK compliance.

The system is also used extensively in other fire-critical areas such as the London Underground, nuclear processing facilities, military facilities, and more thanks to its enhanced fire integrity, low smoke emissions, and low toxicity in fires.

Fire integrity

MARRS Offshore can be used in most areas throughout an offshore installation except in specific areas where post-fire integrity may be required (such as designated safety escape routes).

When installed and used in accordance with Fiber Glass System’s installation and operation procedures, the MARRS Offshore Handrail provides many years of reliable service in your offshore installation.
