Valaris Oil Rig Walkways - Widocryl System

Extreme weather offshore takes its toll on steel.

Replacing a steel roof is extremely costly and demands a rig be returned to port or to a yard for roof replacement.

Water was heavily penetrating through the roof of the

communication and emergency generator rooms. This roof/platform needed to be trafficable for foghorn usage.

Widopan provided WIDOCRYL Special Primer PM

specifically developed for use on metal surfaces and in particular steel.

The Area was assessed and compatibility tests undertaken.

• Rust removed,
• Abraded with flat disc,
• Cleaned with acetone
• Treated with a rust inhibitor.

WIDOCRYL-PM Ten was applied on top of the primer using a roller.

Detailing points around the fog horn and other upstands and roof penetrations were fully reinforced with polyester fleece. WIDOCRYL-PM

Ten is cold applied and creates a permantly elastic membrane. It's a rapid curing, fully monolithic and self terminating.

A final coating of WIDOCRYL-Topsiegel PM was cold applied as a surface coat. This super hardwearing system was also used together with sand to create a non-slip walkway to the foghorn.
