MARRS Offshore Handrails

MARRS® (Multi Angle Rapid Railing Systems) Offshore is a unique patented FRP handrail system designed and developed in-house to meet the required strength, toughness, fire reaction performance and safety properties required for offshore oil and gas installations. MARRS Offshore has been awarded American Bureau of Shipping (ABS) Type Approval and Det Norsk Veritas (DNV) Type Examination certificates and is fully NORSOK compliant.

Due to its enhanced fire integrity and very low smoke and toxicity emissions this product is also used extensively in other fire critical areas such as underground passenger transportation, nuclear processing facilities, military facilities etc.

Fire Integrity:

MARRS OFFSHORE can be used extensively throughout an offshore installation except in specific areas where post-fire structural integrity may be required (such as designated safety escape routes). Please refer to the MARRS Offshore Type Approval for further information?

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

Client feedback following Clair Ridge project completion:

“The innovative Phenolic FRP composite structural products, including MARRS® OFFSHORE handrails, access structures, ladders, safety gates and grating have been designed, supplied, and installed extensively throughout the BP Clair Ridge project, all performing beyond expectations throughout fabrication, and passing Lloyds Class Project testing. The team also provided expert technical and engineering services as part of a packaged-solution from design to completion.

The FRP products successfully provided a cost effective, corrosion resistant alternative solution to steel equivalents and made a significant contribution towards critical weight saving objectives. ” – Lead Topside Structural Engineer, BP
