About

Drygon Consulting Inc., previously located in Calgary, Alberta, Canada, is no longer active. It had provided engineering and project management information and services. This Drygon website continues to be the home of the unique Discipline Interface Charts which were developed and designed by Tony Yep. These drawings provide the detailed sequence of engineering work activities and deliverables which are to be maintained and managed to ensure the successful execution of major projects. This website allows users to access these drawings directly on-line for reference purposes, and to improve their engineering execution and project management skills.

Tony Yep had been a professional engineer working at a major EPC (Engineering, Procurement and Construction) company in Calgary for over 20 years. There, he held key positions of Mechanical Department Chief, Project Engineer, Manager of Engineering and Senior Project Manager working on large-scale projects related to the oilsands, petrochemical and refinery industry. His last major project was the $4 billion Secondary Extraction Plant of the Suncor Fort Hills Project in Alberta. This was completed and successfully started up in 2017. He became a consultant, acting as the Manager of Engineering, leading a team of professional Canadian engineers who reviewed and validated all the engineering designs done overseas by a major South Korean EPC company.

Retired again since 2014, he has pursued his interests in the written words, by being a self-published author of multiple books and in collecting articles worth reading and being creative in doing artwork designs. This website includes many diverse written articles and some of his best artwork designs and photos taken from his travels around the world.
