Interlock Technology Improves Process Safety in Tanker Loading/Unloading Operations

image009Kirk Key’s (Kirk) Eagle Series interlocking products provide process-safety control in tanker loading and unloading operations. The company’s trapped key interlocking systems ensure that users follow a pre-determined sequence of operation for activating road, rail, and sea tanker control valves in oil refining, petro-chemical, pulp and paper, liquefied gas and other industrial applications. Kirk Eagle Series valve interlocks integrate with its mechanical and electromechanical trapped key interlock series to form a comprehensive safety scheme.

According to the manufacturer, product-transfer procedures that rely on manual control can lead to spills or leakage of hazardous gases or liquids, causing injury, property damage and potential fines. By controlling a defined sequence of equipment operation, such hazards are minimized.

The company says its interlocking systems are designed to site requirements and ensure that safety processes move smoothly across a range of equipment including road, rail or marine barriers, hoses, gantry accesses, valves and pump electrical switches. Each step in the scheme releases a uniquely coded key required to move safely on to the next step of the sequence. These oversized keys can’t be duplicated and the sequence can’t be circumvented.

The Eagle Series includes integral valve interlocks to fit every type and size of quarter and multi-turn valves, as well as bolt and electro-mechanical interlocks. To support long-term use in harsh environments, all Eagle Series products are manufactured entirely of 316 stainless steel and incorporate keyways that are protected by a gasketed flip covers.

High Integrity Safety System Works Alone or With Any DCS, PLC or HMI

Screen Shot 2014-06-09 at 11.07.08 AMABB has released its High Integrity (HI) safety system for use with any ABB or third-party control system, PLC or operator interface. This TÜV certified release lets users leverage the system for any SIL 1-3 application and to interface all necessary information to the existing control system and/or operator interface.

The offering includes an object-oriented engineering environment with SIL certified safety libraries that efficiently support reuse and engineering throughout the entire safety lifecycle. The engineering environment includes IEC 6113103 programming languages and the easy to use Diagram Editor as well as safeguards against non-SIL compliant configurations.

Core functions include system security, access control, confirm operations, force control, time-tagging to millisecond accuracy, audit trail, system diagnostics and difference reporting, all of which provide an extra layer of authentication for maintenance bypasses and force control, as well as enhanced capabilities for troubleshooting and root-cause analysis.

According to ABB, its new Independent High Integrity system is well suited to applications where deep integration with the process-control system isn’t required, such as relay replacements or systems where visualization is provided by an ABB or third-party process panel, simple HMI or control system. The HI hardware and engineering tool are also used with ABB’s Freelance and Symphony Plus control systems to deliver safety solutions that are SIL3 certified to Edition 2 of the IEC safety standards
