Drill ship power challenge: hybrid solution solves distribution issues
Aspin Kemp & Associates (AKA), a manufacturer of electrical power and control systems headquartered in Montague, PEI, encountered one with its hybrid power initiative, the first hybrid drill floor destined for installation on ultra-deepwater drill ships operated by Transocean, Swiss offshore drilling contractors. Since on-site modification was impossible and scrap recycling of any modifications was unacceptable, the enclosures had to arrive ready-to-install.

Ensures Tanker Safety and Emissions Compliance
Storage tanks are irregular in shape and a certain amount of mathematical modelling is required to get an accurate representation of volume and, more importantly, the weight of material in each tank. In addition, countries have different emission regulations, so the ships position needed to be accurately known in order to geotag emission data.

Real-time Networked Sonar System for Ships
A multinational, knowledge-based corporation that delivers marine electronics solutions is utilizing industrial Ethernet technology to help ensure that operations at sea are dependable and optimal. Based in Europe, the company has nearly 4000 employees working in 20 countries around the world, and produces high-tech systems for offshore oil and gas operations, merchant marine systems, and various applications for the defense and aerospace industries. The company produces products and systems used by merchant vessels and offshore installations for positioning, navigation, automation, as well as for surveying and monitoring the seabed, and for fishing vessels and fi sheries research. As one of the major suppliers of high quality marine electronics in the world, their products include chart plotters for yachts, triple redundant dynamic positioning systems for oil drilling rigs, and sonar and instrument systems for scientifi c research vessels. Products used for marine applications must be rugged enough to endure the corrosive effects of salt water, and be able to withstand excessive amounts of vibration and shock. For this reason, the company only uses DNV and GL certified products and components to ensure that their systems can meet the high standards required by the maritime industry.

Mitsubishi Electric's Edge Computing Solution Powered by Wind River VxWorks
Mitsubishi Electric Corporation, a global leader in factory automation (FA) applications, identified edge computing as a critical component of the Industrial Internet of Things (IIoT). The company aimed to enhance device and data security, reduce data traffic to the cloud, and enable faster response to network or device issues. In 2018, Mitsubishi Electric launched its first line of industrial hardware products designed for edge computing, the MELIPC Series. The primary development goals for MELIPC were to support the type of edge computing promoted by Mitsubishi Electric and to introduce advanced vision technology for device control. The flagship computer of the MELIPC line, the MI5000, was designed to combine real-time equipment control with high-speed data collection, processing, diagnosis, and feedback in a single machine. However, the development team needed a real-time control platform that could seamlessly integrate real-time control with proven analytic and diagnostic applications.
