Keeping LNG facilities safe and sound

LNG facilities face growing pressure to improve safety, reliability, and operational efficiency while managing complex process conditions. This white paper examines how advanced ProRox® stone wool insulation systems from ROCKWOOL Technical Insulation can help operators address two critical industry challenges—operational noise and corrosion under insulation (CUI)—without compromising thermal performance.

The safety risks of excessive operational noise

Noise is one of the most common hazards in LNG facilities. Pumps, compressors, valves, turbulent flow, and piping systems can generate sustained high-noise levels that affect worker safety, communication, and operational efficiency.

The risks and costs of CUI

Corrosion under insulation remains one of the LNG industry’s most persistent and costly integrity threats. Moisture intrusion beneath insulation systems can accelerate hidden corrosion on piping and equipment—particularly in LNG facilities experiencing thermal cycling and condensation.

In this white paper, you’ll discover

• How insulation systems influence both acoustic performance and corrosion resistance in LNG facilities
• The operational and safety impacts of excessive industrial noise
• Why LNG facilities are especially vulnerable to corrosion under insulation (CUI)
• How ProRox stone wool insulation helps reduce sound transmission in piping systems
• The importance of testing to industry standards including ISO 15665, CINI 9.2.11, ASTM G189, and ASTM C1617
• How advanced ProRox PS965 with CR-Tech® (Corrosion Resistant Technology) provides additional protection against moisture-related corrosion
• The operational benefits of combining acoustic control and corrosion mitigation in a single insulation solution
