Alaskan pipeline flows with Modbus TCP in its industrial Ethernet

Enhanced automation architecture for the Trans Alaska Pipeline System provided capability to remotely operate the system, incorporating Modbus TCP in its industrial Ethernet network technology. See diagram.

Portland, ME – In an industrial Ethernet networking application, Alyeska Pipeline Service Co. (APSC) operates the Trans Alaska Pipeline System (TAPS), 800 miles from Prudhoe Bay through rugged terrain to Valdez, the northernmost ice-free port in North America. 



APSC has transported more than 15 -billion barrels of oil via TAPS since pipeline startup in 1977. Automation software that connects to the Ethernet, whether running on commercial or industrial hardware, is already inherently “rugged” in nature with built- in retry logic and error correction as common functionality, Kepware says.

A recent project enhanced the TAPS automation architecture and provided the capability to remotely operate the system. APSC identified that installing new equipment would alter hydraulic and operating parameters, explained Tony Paine, CTO of Kepware . To predict and modify programming and operating configurations prior to installation, APSC engineers decided to create a rugged simulated I/O and valve system, mirroring live conditions.
Components, explains Paine, include Allen-Bradley ControlLogix PLCs by Rockwell Automation , ICS Triplex PLCs , I/O simulator by Telvent , and a valve simulator configured in a UCOS distributed control system (DCS).

To complete the system APSC engineers needed to link these virtual control components and I/O components, Paine says. The system integrator used Kepware’s OPC server KepServerEX with DDE Client driver plug-in and Modbus TCP/IP master driver plug-in. Kepware’s OPC server bridging product LinkMaster pumped data among connectivity components.
The configuration (see diagram) mimicked lab-based controllers and field I/O to “test and troubleshoot certain aspects of our system before the programming reaches the field,” says Jim Foster, the lead APSC engineer on the project. “The simulation system will also be used to test and qualify the control center operators in conjunction with other training tools,” Foster added.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
