ABB helps bring gas field pipeline on stream

Massive gas field will supply 20% of the United Kingdom's gas needs through the world's longest underwater pipeline. The automation system, one of the largest ever delivered by ABB, is based on System 800xA Extended Automation.

The giant Ormen Lange gas field in the Norwegian Sea will supply 20% of the United Kingdom's gas needs through a 1,200-km underwater pipeline, reportedly the longest in the world.

Equipped with cutting-edge ABB automation, electrification, and telecommunications systems, the project officially opened on Oct. 6. When full production capacity is reached later this year, the field will supply 70 million cm of gas and 50,000 barrels of condensate a day to provide the UK with a stable and reliable natural gas supply for the next 40 years.

Located 800 to 1,100 m below the surface in the extreme weather conditions of the Norwegian continental shelf, Ormen Lange is the deepest natural gas field ever tapped. Gas is piped 120 km to the Norwegian mainland for processing, then pumped through a 1,200-km pipeline to the east coast of England for distribution in the UK supply network.

ABB's participation in Ormen Lange is extensive and crucial to the success of the project. Its control, safety, and information management systems manage the gas processing plant and the flow of gas through the pipeline. Based on ABB's market-leading and award-winning Extended Automation System 800xA, the system is one of the largest automation systems ever delivered by ABB.

In addition, ABB has supplied an energy-efficient, all-electric variable speed drive solution to power and control the gas compressors at the Nyhamna onshore processing plant. Compared to turbine-driven compressors, ABB's Megadrive-LCI variable speed drive system offers considerable savings in operating costs and fuel consumption; reduced greenhouse gas emissions; and improvements in availability, productivity, and energy efficiency.

Emerson automates Chinese petrochemical plant

Emerson Process Management has been selected to digitally automate the Fujian Refining and Ethylene Joint Venture Project in Quanzhou City, Fujian Province, China. It is the largest integrated refining and petrochemicals project ever undertaken in China. Startup is expected in 2009.

Emerson completed front-end engineering and design in September 2006, and is now proceeding with project management, engineering, integration, testing, commissioning, and other site services. Emerson also will serve as the main instrument and controls contractor (MICC) on the project, and will install its PlantWeb digital plant architecture. The PlantWeb installation will include eight DeltaV digital automation systems, AMS Suite software, a safety instrumented system (SIS), fire and gas systems, Rosemount pressure and temperature transmitters, and Fisher digital valve controllers. All systems use FOUNDATION fieldbus, HART, OPC, and Modbus communication technologies, and deliver information to a real-time database.

"Emerson's goal is to design a reliable, advanced instrument and control system to assure safe, stable, and long-term quality operations while maximizing the profitability of the company," said Hongye Hu, MICC manager, Fujian Refinery. "Emerson has proven technologies and a proven track record in China. Emerson's local resources and the support of its global resources help to mitigate and minimize risks for owners."

Emerson's PlantWeb digital automation solution networks intelligent field devices and sensors throughout the facilities, collecting and reporting real-time predictive data about the process, instruments, and equipment. Operators and maintenance personnel will use the predictive data to optimize performance and anticipate issues, and correct them before operations are interrupted or shut down.

E+H offers two-wire in-line ultrasonic flowmeter

Endress+Hauser's new Prosonic Flow 92F FOUNDATION Fieldbus 2-wire in-line ultrasonic flowmeter consists of a bus-powered transmitter and multi-beam ultrasonic inline sensor. It offers high accuracy (better than 0.5%, optional 0.3%) and cost effective, non-invasive flow measurement.

Measurements require no mechanical interaction with the flow, making it virtually maintenance free and without additional pressure drop. The arrangement of the ultrasonic sensors ensures optimal scanning of the flow velocity distribution in the measuring section of the sensor, reducing the need for upstream straight pipe to less than five times the pipe diameter.

Prosonic Flow 92F is suitable for service in the chemical industry. It measures both electrically non-conductive and conductive liquids, including solvent and hydrocarbon derivatives, and complements the application range of electromagnetic flowmeters for both process and utility applications.

Moore Industries temperature transmitter cuts installation costs

High-accuracy TFZ Fieldbus temperature transmitter from Moore Industries, the parent company of fieldbus interface solutions division MooreHawke, saves wiring and installation costs. Up to 32 TFZ transmitters can be installed on the same segment with all standard fieldbus devices. The TFZ converts a sensor input to a FOUNDATION fieldbus H1 ready for interface to a DCS, computer-based SCADA system, or asset management software.

Bus-powered device features 20-bit input resolution, and offers dozens of input and operation choices. It sets up from the control room over the segment wiring, using a standard FOUNDATION fieldbus configuration tool to handle 14 RTD types, nine thermocouple types, and direct millivolt and resistance/potentiometer inputs.

The TFZ is Fieldbus Foundation registered, CE conformant, and certified as an intrinsically safe, non-incendive, and Type N apparatus. It has cFMus (Canada & US), ATEX, and IECEx approvals for use in Zones 0/1/2, Class I, Div.1/Div.2 hazardous classified areas.

MTL diagnostic module delivers fieldbus diagnostics

MTL F809F diagnostic module for use on FOUNDATION fieldbus networks offers a unique overview of the physical layer status by being installed as a fieldbus device. This application enables the module to communicate directly with the network control system over existing network wiring and infrastructure and present diagnostic information directly within the instrument management software. The F809F is the first diagnostic module registered by the Fieldbus Foundation and represents a significant advance in the way diagnostic information is processed and presented to end users.

The physical layer is critical to the performance of the fieldbus system. During commissioning, the F809F collects data on the performance of the physical layer, provides alarms if any parameter is outside preset limits, and stores a baseline of segment performance in the system's instrument management software. The investment in fieldbus diagnostics typically is recovered during commissioning.

"Fieldbus end users, engineering contractors, and automation suppliers recognize the value of a fully integrated fieldbus diagnostic solution. This is demonstrated by MTL having shipped F809F modules to monitor over 6,000 fieldbus segments during the past three months," said Roger Highton, MTL fieldbus product manager.

P+F intrinsically safe isolators connect field devices via Ethernet

Pepperl+Fuchs' new intrinsic safety FieldConnex Ethernet Isolators are galvanically isolated Ethernet devices that allow users, for the first time, to connect high-speed data devices located in hazardous location applications directly to a standard Ethernet line. They also allow for back-to-back "pass through" applications without requiring separate hardware. OEMs can benefit, says Pepperl+Fuchs, from a specialized PCB-mounted version that allows them to integrate intrinsically safe Ethernet seamlessly into their own equipment.

FieldConnex Ethernet isolators combine intrinsically safe energy limitation and galvanic isolation into one product. The isolator can be installed in a safe area, or in a Zone 2 or Zone 1 area when housed in a suitable enclosure. Two isolators must always be used together, as combining the isolators creates an intrinsically safe link that can be routed through a Zone 0 or Zone 1 hazardous area.

The device makes Ethernet cable installation intrinsically safe by limiting the energy that can be delivered from the non-hazardous to the hazardous area, while still allowing full Ethernet communications data to pass through a device. Galvanic isolation eliminates equi-potential bonding and solid grounding between the area of installation and the connection point in the hazardous area. Combined with safe energy limitation, galvanic isolation also eliminates the need for expensive and inflexible hazardous area conduit applications. This new category of Ethernet isolators is compatible with all IEEE standards, and provides high noise immunity and low heat dissipation in a compact housing.

R. Stahl mini-terminator for explosion-protected H1 installations

New, compact terminating resistor type 9418 for explosion-protected FOUNDATION fieldbus H1 installations from R. Stahl comes in two build types for use in Zone 1 and Zone 21. An Ex i terminator is available for intrinsically safe (IS) fieldbus installations, and an Ex m model is offered for power trunks that are not intrinsically safe. Designed to fit in M20 cable glands, 9418 terminators can be attached easily to cable entries of field distribution panels or field devices.

Fieldbus standards call for the presence of a defined terminating resistor on both ends of a bus trunk as a measure to avoid signal reflections. Although the power supply unit on one end of the bus usually comes with an integrated terminator—as is the case with R. Stahl's 9412 fieldbus power supply—the other bus end in the field must also be electrically terminated. Some devices typically found there, such as 9411 Ex i and Ex e field device couplers, feature built-in terminators for activation on demand. Others, such as R. Stahl's new type 9413 digital I/O coupler, require a separate one such as the new 9418 terminator, if they are last in line on a fieldbus trunk.

TopWorx valve controllers reduce segment requirements

Understanding that the cost of FOUNDATION fieldbus installations is driven largely by the number of segments required, TopWorx designed valve controllers that reduce the number of segments end users need.

TopWorx valve controllers need only one function block. Traditional valve controllers require a minimum of three to handle two switch inputs and a solenoid output. Why is this important? Requiring 2/3 fewer function blocks creates a domino effect that leads to significant cost savings throughout the entire installation For example:

1. Fewer blocks mean quicker device execution time per segment;
2. Quicker device execution time means more devices per segment;
3. More devices per segment mean fewer segments;
4. Fewer segments lead to reduced hardware and software licensing costs; and
5. Reduced costs mean real savings.

By choosing TopWorx, end users can expect a reduction in:

  • H1 cards;
  • Power supplies;
  • Power conditioners; and
  • Annual software support cost.
