Turnaround Services
HSOS bundles key TAR activities into one strong team of specialists – fewer interfaces, less waiting, shorter downtime.
Turnaround from a single source
With our TAR programme we deliver specialised turnaround services from a single source — every relevant service bundled into one coordinated team: bolt-tensioning, heat treatment, on-site machining, hot tapping, leak sealing and composite repair.
Plant operators and EPC contractors benefit from shorter shutdowns, less interface coordination and a continuous documentation chain to ISO 9001 and ISO 45001.
One brand, one team, every TAR discipline. Fewer interfaces, clear responsibilities, shorter outages.
Thanks to our many years of experience in more than 100 turnarounds and Europe’s largest TAR-specialised equipment fleet, we can react at very short notice – even for unplanned work or requirements.
By bundling all TAR specialist services under one roof we drastically reduce interfaces and coordination effort – saving time and money.
