Maintenance and Inspection Engineering (MIE)

Maintenance and Inspection Engineering (MIE) is an integral part of a technology management system, aimed to identify methods for developing and selecting maintenance and inspection strategies and design alternatives, based on operational, economic, safety and environmental criteria.

ISSAC E&C applies systematic approaches for establishing a maintenance and inspection program, which will efficiently and effectively allow the achievement of the required safety and availability levels of equipment and structures, intended to result in improved overall safety, availability and economy of operation.

The main objective is to provide a comprehensive and structured set of knowledge, addressed to the effective management of technology projects issues in compliance with international standards, national regulations, client procedures and specifications, together with reference best practice and techniques.
