Our expertises

Industrial plant shutdown assignments

Technical shutdowns, these planned interruptions to production plants are essential for checking the condition of equipment and for carrying out maintenance, modernisation, extension or cleaning work. These major operations are a regulatory requirement for industry and one of Ortec’s specialities.
With full understanding of the aspects of these operations, the Group combines thorough advance preparation with its Engineering teams, synergy between the different divisions and operating efficiency to ensure production is maintained and facilities restarted rapidly and reliably, with the aim of optimising production resources.

Synergy, Ortec’s strength

Taking advantage of synergies and combining different skills on complex work sites is one of our Group’s great strengths. Some can involve several hundred employees. So it was that eight branch offices contributed on the ground to the in the three-yearly shutdown of the Solvay Group’s Hexamethylene diamine (HMD) plant at Chalampé (Haut Rhin) for two weeks of major works. Mission accomplished!

The berre petrochemical unit, maximum mobilisation

250 Ortec Group employees per day for five weeks – that’s how many of our employees were mobilised for the major shutdown of the plant on the Berre petrochemical unit in 2016. On their agenda: replacing a fully equipped column, ‘Oxygen’ configuration work on a butane tank, removing the front plate of a 2.5 m diameter fixed heat exchanger, verification of 210 static equipment items, 500 taps & valves and 270 fire points, and carrying out 170 tests and trials.

Innovation to support major shutdowns

At Ortec, digital is becoming increasingly important in preparing for major maintenance shutdowns, as in carrying out and monitoring work. We innovate continuously, with a challenge: digitising our methods and all processes, from sharing documentation to processing information. Using the Digital Forms application, field surveys are now carried out on a tablet, which makes data more reliable to transfer and easier to process.
