Powerline-communication chipset
e STMicroelectronics ST8500 is a powerline- communication (PLC) solution which features a G3-PLC CENELEC B certi ed protocol stack for industrial applications beyond utility metering. In addition to covering all G3-PLC standards and frequency bands, ST8500 also o ers certi ed libraries for all PRIME standards, from PRIME 1.3.6 to PRIME 1.4 in CENELEC and FCC bands. Each of the stacks features high-performing routing algorithms to ensure network coverage in all application domains. Fully programmable, containing a dedicated real-time engine to handle the modulation and coding schemes of di erent PLC standards and a power-e cient Arm Cortex-M4F core for upper-layer processing and system management, the ST8500 allows product manufacturers to address multiple markets and regions with a single hardware platform, and future-proof assets in the eld by remote update. Dedicated peripherals for smart-energy applications, including an AES cryptographic engine, are also integrated. Consuming less than 100mW
in receive mode, the ST8500 meets stringent industrial speci cations to minimize the grid load imposed by new smart meters. With a complete Analog Front End (AFE) on- chip, the ST8500 connects directly to ST’s STLD1 line driver
to create a complete single-vendor powerline-transceiver solution. e STLD1 ensures reliable communication even across noisy cables, with high drive capability and high linearity over a wide output range of 18V in single-ended
or 36V in di erential mode. e two-chip set delivers high performance, low power consumption, exibility, and cost- e ective connectivity for smart-grid and IoT applications.

Service accommodation and transfer vessel
Damen Shipyards Group’s new design, e Fast Crew Supplier (FCS) 3410 service accommodation and transfer vessel (SATV) contains numerous design features that ensure its suitability for operations in the developing o shore wind market in North America. e premise of the design is the Damen Twin Axe bow design. e Axe Bow allows the vessel to cut through waves instead of slamming, signi cantly improves seakeeping and onboard comfort. e FCS 3410 is 6 metres longer than previous FCS types and able to host more on board personnel
and accommodation. e FCS 3410 is also designed for transporting and providing accommodation for o shore personnel for up to a month. e FCS 3410 would be built on location in the United States. For many years, US partner yards have built Damen designs at domestic locations, providing American ship owners with access to Damen’s designs while complying with the requirements of the Jones Act. is process, the Damen Technical Cooperation, ranges from simple licensing up to the delivery of full materials package, including technical support.

Identifying wind component failures before they occur
Predict, Greenbyte Energy Cloud’s new feature uses statistical models, arti cial neural networks, and machine learning to identify wind turbine component failures
before they occur. e feature alarms users on changes in temperature that indicate need for maintenance. Predict’s advanced statistical models developed by Greenbyte’s Head of Research, Dr. Pramod Bangalore have been optimized
for high accuracy and in collaboration with Greenbyte’s R&D Department, been put to vigorous testing to ensure high accuracy. Predict estimates the expected temperature for critical components, compares that estimated data to the actual measured values, and enables intelligent and early detection of developing failures. e pilot study on Predict detected faults 2 to 9 months in advance, achieved 94% accuracy and showed a 23% reduction of cost, and the software keeps learning and outperforming itself.

Online imagery portal with analytics
Spottitt Ltd. has launched a cloud-
based workspace that puts satellite imagery sources and advanced analysis capabilities at the ngertips of energy, environment, and infrastructure professionals. e Spottitt service is available through Veracity, DNV GL’s industry data platform and online marketplace. e Spottitt online portal gives users instant access to multiple satellite image sources, including open source data from the U.S. Landsat and European Sentinel-2 satellites and sub-meter commercial image products from Airbus Defence & Space and DigitalGlobe. Other geospatial products include Digital Elevation Models (DEMs) and infrastructure feature layers. e major di erentiator of Spottitt is the powerful data analytics it o ers in the cloud. e user selects from a variety of enhancement and information extraction algorithms that can be applied to their chosen data set. Spottitt workspaces are securely hosted in the Microsoft Azure cloud, giving clients access from any browser-equipped device at any time. Clients are o ered the option of paying for imagery and processing as they go or under subscription arrangements.
