Posted in Courses

Overview

Tetra Engineering Group, Inc. (TETRA) was established in 1988 in the USA and since then has been providing specialized engineering services to operators of power generation boilers and thermal process plants worldwide.  Starting in 1993, TETRA was one of the first companies to perform HRSG inspections independent of the OEMs.  They have conducted over 1000 HRSG & Boiler inspections at more than 250 power plant sites located throughout the world. This training course was developed using that extensive experience.  While it primarily intended for O&M staff working in the plants, the content is also very relevant to corporate engineering and plant management. The overall objective is to give attendees comprehensive insight into how to efficiently plan, execute and document a short and long outages. The course is run over 2 consecutive days.
