Oil overflow terminals, oil refineries, and other similar facilities

Such complex technical structures consisting of a great number of different pipelines and additional equipment require greater monitoring, maintenance, and repair by the best specialists in the industry.

Work planning and risk analysis before the production shutdown is the most crucial part of the process. Our experts thoroughly discuss with the Client all the project details and present optimal timely workflow solutions.

We own a series of in-house WPQR and WPS. We can also design, and attest required materials, in case our ready-made don’t fit on Client site.
