Applications
Critical Infrastructure Monitoring
Based on a proven track record our Distributed Fiber Optic Sensing (DFOS) solutions ensure reliable asset protection even in the most challenging environments. We have established ourselves as the leading solution in awide range of applications.
Offshore
PWHT and induction heating systems for offshore platforms, subsea structures, and topside fa rication.Providing controlled thermal processing for reliable weld quality in demanding marine environments.
Offshore Oil & Gas Infrastructure
Offshore construction requires strict safety standards, structural reliability, and precise thermal control in harsh marine environments.
Induction heating and post weld heat treatment (PWHT) systems provide flame-free preheating and controlled heat treatment for critical offshore welds.
For LNG and cryogenic applications, our thermal solutions ensure uniform heat distribution, while electromagnetic levelling corrects plate deformation without flame straightening.
Engineered for heavy offshore projects, these systems deliver reliable performance, improved weld integrity, and enhanced safety.
Pipeline
Induction heating and PWHT systems for pipeline fabrication and installation. Providing controlled preheating and heat treatment to ensure weld quality, structural reliability, and compliance in onshore and offshore projects.
