Users seeking appropriate process safety systems arent getting enough help from unspecific standards and ideal-world certifications. Heres how to gain useful safety capabilities in a buyer-beware world.
For maintenance and condition-monitoring, wireless technology offers much more than just reducing or eliminating costs. However, wireless also requires an integrated infrastructure approach rather than independent, proprietary point solutions.
Enhancing safety performance requires diligence and unrelenting effort. The Independent Safety Review Panels recently released report on the safety culture and practices at BPs U.S. refineries where a March 2005 explosion occurred in Texas City, Texas indicates similar failings are likely elsewhere in the industry. Learn what can be done to enhance continuous safety improvement.
Consider the impact of slope, fittings and valves. Plants can lose sizable amounts of money each year because of contamination caused in process lines. Owners and contractors alike can take steps in the design and construction phase to enhance the drainability and cleanability of a system.
There are two main drivers for partial stroking of valves in safety systems: the desire to extend manual test intervals to as long as possible; and to reduce the amount of redundant hardware required for higher safety integrity levels. Like most things in life, it all boils down to one thing: trying to save money.
Understanding the purpose of control and safety systems helps users ensure each is appropriately optimized. The duties of the SIS are to protect the people, environment and assets against unsafe conditions.

More and more companies are placing greater emphasis on maintenance and seeking help from vendors to boost the effectiveness of their efforts, as some recent major investment decisions demonstrate. Many automation companies now are benefiting by building up asset management services alongside process control capabilities.
Your current control system can probably do more than you think. Everybody can agree that diagnostics are a good thing they can identify problems early, and keep the plant running at peak performance. Learn how your existing control systems and analog instruments can deliver diagnostic capabilities, at a fraction of the cost of system or instrument replacements.
