Yokogawa/Cosasco ISA100 deal

Yokogawa has signed a sales agreement with Rohrback Cosasco Systems, a US-based manufacturer of corrosion monitoring systems to distribute the Cosasco ISA100 wireless-based MWT-3905 and CWT-9020 corrosion monitors: also Cosasco will distribute the Yokogawa ISA field wireless system devices. Yokogawa systems operating to ISA100.11a-2011 include an application layer with process control industry standard objects, device descriptions and capabilities, a gateway interface, infrared provisioning, and a backbone router.

Yokogawa therefore has now added corrosion sensors to its line-up of field wireless devices that help customers efficiently maintain facilities and ensure safety at their plants. For Cosasco, the ability to offer its corrosion monitors in combination with Yokogawa field wireless devices is expected to increase sales.

Yokogawa Objectives

With a field wireless system, plant field devices and analysers are able to communicate wirelessly with host-level monitoring and control systems. The rising need to improve productivity and enhance safety by collecting more data on plant operations is driving the demand for field wireless devices, which can be installed even in difficult to access locations. Field wireless devices have the added advantage of reducing installation costs.

Yokogawa has developed ISA100 Wireless-based technologies and products such as wireless access points and management stations, and Cosasco has a long global track record in supplying various kinds of corrosion monitors to the oil and gas, petrochemical, chemical, and other industries. Through this agreement, Yokogawa aims to increase sales for its field wireless business by being able to offer a wider field wireless device lineup.

Cosasco Wireless Corrosion Monitors

Yokogawa IA - Cosasco MWT-3905 corrosion monitorCorrosion sensors monitor the thinning or deterioration of the metal walls of pipes and other installations. A variety of technologies are employed, including electrical resistance and ultrasonics. The Cosasco MWT-3905 and CWT-9020, the devices covered by this sales agreement, are direct measuring type corrosion sensors that use high speed electrical resistance and linear polarisation resistance (LPR) technology. This enables corrosion rate measurement at a low installed cost in all process environments, including hazardous areas. The units are particularly applied for the monitoring of corrosion in facilities at offshore platforms and other types of oil and gas installations, plus petrochemical plants, chemical plants, and water and sewage treatment plants.

Rohrback Cosasco is a part of Halma plc, a UK conglomerate.

Emerson acquires PermaSense

Emerson has announced the acquisition of UK-based Permasense Ltd, a leading provider of non-intrusive corrosion monitoring technologies for the offshore and onshore oil production, refining, chemical, power, pipelines, metals and mining and other industries. Permasense monitoring systems use unique sensor technology, wireless data delivery and advanced analytics to continuously monitor for metal loss from corrosion or erosion in pipes, pipelines or vessels, and reliably deliver high-integrity data from even the harshest environments.

The acquisition represents another step forward in the Emerson strategy to invest in its core business platforms and expand in markets that hold significant long-term growth opportunity.

“Corrosion and erosion can significantly impact the safe and reliable operation of our industrial customers’ infrastructure, which can have dire consequences. Wireless non-intrusive corrosion monitoring is a transformational shift that helps customers immediately understand the health and integrity of their infrastructure in real-time and enables them to fully optimise their operations while maximising safety,” said Mike Train, president, Emerson Automation Solutions. “For example, with the increasing complexity of the types of crude oil coming into a refinery, corrosion is becoming a significant issue in the uptime and profitability of a refinery. Now refinery infrastructure can be monitored and controlled using this non-intrusive technology.”

The Permasense product line will become part of the Rosemount portfolio of measurement and analytical technologies. Permasense technologies complement the Emerson Roxar intrusive corrosion monitoring and non-intrusive sand management systems and strengthen the company’s Pervasive Sensing applications that provide customers a more complete view of their operations and facilities. With Permasense and Roxar technologies in its portfolio, Emerson will be the largest provider of integrity and corrosion management solutions in the marketplace.

Lal Karsanbhai, group vp, measurement and analytical technologies, Emerson Automation Solutions, added: “The addition of patented Permasense technologies along with our existing Roxar technologies enables Emerson to provide customers with a more complete corrosion monitoring solution and a clearer picture into the performance of their infrastructure based on what they’re demanding of it and the strategies needed to optimise production.”

Central to Permasense corrosion monitoring systems are sensors that employ proven ultrasonic wall thickness measurement principles. The sensors are battery powered and communicate wirelessly, which minimises the cost of installation and enables use in remote areas and on a large scale. The sensors are also designed so they can be deployed in hazardous areas.
