Hot bolting, or tightening bolts on flanges and other pipeline connectors while in operation, brings dangerous liabilities into fluid control operations. One example of the dangers occurred in 1992 where a hot bolted heat exchanger exploding killing 17 when a gasket-retaining ring slipped upon tightening. One common flaw in operators during maintenance practices is to believe they are more experienced and knowledgeable than is true, the Dunning-Kruger effect.
Bolts are only capable of shifting so far under stress, and during thermal loads the bolt materials may have reduced limits. Hot bolting adds stress to the material and combined with the lower limits these stresses may exceed resulting in ruptures or explosions of hot fluids. To reduce the risks of failure from thermal expansion springs may be added to bolted connections allowing more travel yet providing the needed sealing forces.

A good design to a control room will facilitate efficiency and minimize liability. The design will enhance an operator’s efforts to produce the desired results in production. Since 2000 the International Organization for Standardization has produced a set of standards, ISO 11064, for control room design. Most of these standards deal with ergonomics and layout for the room, and adherence to these standards can greatly protect a company from injury lawsuits.
ISO 11064 helps establish good design standards with measurable results to avoid control rooms like many of us have experienced. Designed control rooms, control buildings and operation camps that feature a user-driven approach, work with ISO 11064 requirements, and integrate architectural, interior design and human-factors elements optimize performance.
First and foremost in the design process focuses on safety; locating the control room outside of blast zones, pathways of heavy equipment, and insecure environments. Further efforts deal with employee access and localities.

Microsoft and General Electric are partnering to improve the online cloud industry with the industrial internet of things in mind. GE’s focus on the industrial and manufacturing sectors will synergize with the technological innovation from Microsoft to provide cloud resource servers and analytics on demand for the burgeoning industry of smart connected devices.
“Companies worldwide will be able to bridge the divide between the operational and information technologies that make up the Industrial Internet of Things,” -Microsoft
This collaboration is set to bring analytics from equipment to a wide variety of operations, with even more reliability for future adopters. GE’s cloud platform Predix will be integrated into Microsoft’s Azure for a final service of; Predix of Azure.

The Haitian electric utility company E-Power S.A. began construction of a 30 Megawatt power facility for Port-au-Prince in 2008. While under construction the 2010 magnitude 7.0 earthquake struck. Along with immense loss of life and mental wel-being for the people, the electric infrastructure of Haiti was irreparably damaged. Recovery was in danger.
“So much was destroyed in 2010 that we had no way for Hyundai to unload the equipment for the new plant near Port-au-Prince,” says Ludwig von Lignau, operations manager at E-Power. “There was also no bridge from the Dominican Republic that could handle this equipment, and so the U.S. Army agreed to build a makeshift dock near the site.”
E-Power’s facility was commissioned to run outdated software as their control system, but in order to better aid with the recovery endeavors leaders implemented a custom controls system redesign. By adapting non standard implementations and culling excessive operator interactions the plant is now providing 35% of the local power with unimaginable reaction time.
“We’re able to respond very fast to changing electricity demand because we can start units in just 10 minutes. We can react quickly to high-frequency requirements.” -von Lignau

In 2013 right before the final switch was thrown on a huge energy demonstration there were a lot of observers with crossed fingers. Despite all the effort and research by engineers in creating the demo, the true test of the system would be the first startup.
“Just because something should work, technically, is no promise it’ll work. We had the necessary systems and engineering skills and experience, but making it real was the challenge.” -John Stampfel, VP & GM of Electrical Engineering Services & Systems
