Shutdown Activities

Shutdowns for scheduled maintenance, cleaning, and servicing measures are a critical time for any operator of an industrial facility. Each day of a plant shutdown translates to revenue loss. Ever more stringent legal regulations increase the requirements for industrial facilities, while the timeframes for these shutdowns are becoming increasingly shorter.

Precise, on-schedule, and reliable – shutdowns with J.Christof

Especially shutdowns of large industrial facilities require proper preparation, precise planning, and outstanding implementation in order to fulfill all the tasks in a timely manner. Every day counts – and nonetheless, it is necessary to ensure the highest quality, precise work, and compliance with safety standards. These are the core competencies of J.Christof.

We assist you both as a general contractor for the shutdown as well as with services. Due to our experience in turnarounds of large industrial facilities in different sectors, we ensure a smooth flow and timely implementation of your project.
