Process & Machinery engineers of Occupational Safety and Health Services, Inc. have years of experience associated with them. They are the expert of the field and most of them have worked for elite brands previously. Lewis Barbe explains about Process & Machinery projects by Occupational Safety and Health Services, Inc., and its team’s areas of specialization.

1. Process & Machinery
ESI’s Process and Machinery personnel consist of senior engineers with extensive
experience in utility and industrial power generation, petrochemical processing,
and other heavy industrial engineering and manufacturing concerns. Prior to
joining ESI these engineers gained their experience in previous technical and
senior management positions at large national and international Fortune 500
companies, major Federal organizations, or independent research laboratories.
Typical Projects Involve:
 Compressors and Compression Stations
 Cranes

2.  Drilling Rigs
 Equipment Failures
 Gas Processing Plants
 Machinery Failures
 Physical and Chemical Explosions
 Pipelines for Oil and Gas
 Power Generation Facilities (including Cogeneration)
 Pressure Vessels
 Production Facilities
 Refineries & Processing Facilities
 Storage Tanks
 Turbo Machinery

3. Representative Projects
The knowledge obtained from prior job responsibilities includes the precise
echnical understanding of complex industrial systems, multidiscipline project
management, and detailed training, safety, and equipment maintenance
requirements. In addition, the senior engineers gained experience interacting
with other organizations and professions, such as, government regulatory
agencies, professional codes and standards committees, legal professionals,
accountants and financial professionals, other organization’s engineers and
managers, labor organizations, subcontractors, etc.
BOILER EXPLOSION
ESI was assigned to investigate the cause of the explosion of a large boiler used
for power generation. The analysis performed by ESI confirmed that the boiler
explosion resulted from the accumulation of combustible gases inside the boiler.
The reason for the accumulation of the gases resulted from the gradual failure of
the combustion air adjustment lever links shown in the picture below.
WASTE HEAT BOILER FAILURE
ESI was asked to investigate the origin of cracking found on a large waste heat
boiler used in an ammonia plant. The analysis done by ESI determined that the

4. cracks propagated throughout the entire thickness, but the origin of the cracks
were determined to emanate from a weld overlay applied to the boiler’s tube
sheet using an incorrect alloy during a prior repair.
GAS TURBINE FAILURE
ESI was asked to investigate the failure of a large gas turbine at a cogeneration
plant. Our investigation determined that the damage resulted from the failure of
a cooling seal that allowed excessive air to enter the turbine’s gas path, causing
high temperature oxidation and the failure of turbine buckets and nozzles.
