Wireless Ethernet modem useful on pipeline spreads
Here's the SRM6200E, a license-free, wireless Ethernet radio modem, specifically designed to operate in the 902-928 Mhz ISM band.
It's suited for pipeline SCADA operations, the company points out. It's useful for spreads where cable installation is difficult or cost prohibitive.
The company notes that this reliable wireless alternative uses MAC layer bridging for true protocol transparency and fully supports TCP/IP-based protocols up to 25 miles away with line-of-sight.
The SRM6200E provides remote PLC programming and diagnostics and wireless connectivity between corporate IS and control.
Interface options include 10Base-T (UTP) to the Ethernet device. The modem is available in stand-alone or PLC rack mount versions.

Underwater survey service offered
This firm offers its HUGIN 3000 untethered autonomous underwater vehicle (AUV) for offshore surveys.
It's equipped with multibeam swath high resolution bathymetry and imagery, chirp side-scan sonar and subbottom profiler, and C-Nav differential GPS integrated with acoustic-inertial navigation and acoustic communications.
The system also includes a high seas launch and retrieval system and is stored in two containers that can be air freighted worldwide.
The AUV is deployed from the mother ship in a free-swimming mode (without umbilical) for up to 50 hr endurance. It surveys at 4 knots in water depths up to 3,000 m before surfacing for refueling of the aluminum oxygen fuel cell.
The HUGIN collects seafloor and subbottom data on a predefined route, while sending subsampled data back to the mother ship for real-time QC/QA via acoustic modem.
On-board engineers analyze the real time data and determine route accessibility. If the route must be altered, program commands can be sent to the AUV via the acoustic modem.
Since beginning commercial operations in January 2001, the company has completed more than 5,500 miles of AUV survey lines. The projects completed thus far have been site hazard and preliminary pipeline surveys.
Although the majority of the 2001 AUV surveys were completed for oil and gas companies with deepwater projects in the Gulf of Mexico, the HUGIN did perform several government site hazard surveys to study the environmental effects of deepwater drilling.

Program aids selection, sale of oil field equipment
Now available is BigMachines for oil and gas field machinery, an industry-specific framework for tailoring this company's software suite for oil and gas field machinery. This web-based software solution is designed to streamline sales processes, including application engineering, quotation, order fulfillment, and aftermarket parts and services for multiple buying and selling parties.
The package is suited for equipment used in onshore and offshore exploration, drilling, and production.
The framework supports frequent, iterative exchange of information as well as customer-specific pricing practices, enabling buyers and sellers to manage quotation, pricing, order fulfillment, and other processes better, the company says.
Its web-based architecture allows implementation teams to set up and administer the program through an intuitive browser interface without programming.

Free catalog features intrinsically safe products
A new hazardous area products CD-ROM, yours free for the asking, offers new intrinsically safe (IS) products, including the latest shunt-diode safety barriers and galvanic isolators, a line of DIN rail and backplane-mounted IS interfaces, a line of IS proximity sensors, and the new fieldbus connection system (FCS Series).
The IS proximity sensors include inductive and capacitive sensors available in a variety of package types to meet hazardous location sensing needs. The company says its new FCS Series of wiring components and fieldbus test equipment can save time and money in fieldbus applications.
Advanced developments in HART maintenance products and IS solenoid valves are also covered.
The catalog also contains sections on surge protection products, as well as information on choosing the right product for your application, installation tips and tricks, and application information.

Retrievable bridge plug
The new Isolator retrievable bridge plug (RBP) consists of packer-type sealing elements, mechanical slips, and a ball valve section.
The sealing elements are less susceptible to damage while running in the hole because they are not in contact with the casing, the company points out. When set, the RBP does not move up or down the casing, regardless of pressure reversals.
The plug can be run alone on tubing or can be run below the RTTS or CHAMP packer.
The tool is run in the hole, set, and released from the tubing or packer. It remains in place until the tubing or packer is relatched, the ball valve is opened, and the slips are released.
