Incredible Engineers

Range of Services

The Basis

Key Success

Incredible Engineers

Our incredible engineers embody strong relevant experience in all area including practical aspects related to Constructability, Commissioning, and their subsequent operation.

Range of Services

Black Cat offers a range of services from Engineering Consultancy, Feasibility, Frond End Design (FEED) Studies, Detailed Design and Engineering (DOE) with disciplines including Civil, Structural, Mechanical (Static/ rotating) Technical drawings and specification preparation, piping/ pipelines, and controls, electrical and instrumentation.

The Basis

The basis on which BCCES works is that all our engineers must have experience not only in design of these facilities, but in the practical aspects related to constructability, commissioning, and their subsequent operation.
