Cryogenic storage tanks for LNG and ethylene operate under extreme temperature conditions and require the highest safety standards. Undetected leakages between the inner and outer tank walls can lead to cold spots, product losses, mechanical stress, and the formation of explosive gas atmospheres.
During tank cooldown and loading phases, uncontrolled or uneven temperature distribution may cause structural deformation and increased safety risks. Early detection of temperature anomalies is therefore essential to mitigate risks, protect personnel, and ensure long-term asset integrity.
The Detection of Leakages in Cryogenic Tanks solution from Endress+Hauser continuously monitors shell and skin point temperatures across the tank base, walls, and roof. This enables early identification of insulation failures or leakages, supports safe cooldown procedures, and helps eliminate unaccounted losses while ensuring compliance with international safety and Ex standards.

Early leak detection in cryogenic tanks – maximum safety, zero unaccounted losses, and full transparency with Endress+Hauser
The solution enables continuous, real-time temperature monitoring of cryogenic tank shells and internal walls. By detecting abnormal temperature patterns early, potential leakages and insulation failures can be identified before they escalate into safety incidents or structural damage.
Certified components and Ex-approved devices ensure safe operation in hazardous environments. Advanced pre-engineering, including temperature profile mapping, supports optimized sensor placement and validated design. The solution integrates seamlessly into Endress+Hauser tank gauging ecosystems and can be expanded with digital services for enhanced transparency and long-term asset protection.
