Norwegian energy company Equinor has awarded a letter of intent to Odfjell Drilling to deploy the Deepsea Atlantic rig for the second phase for the Johan Sverdrup field development.The drilling programme is planned to commence in 2022, and will include 12 wells with an option for an additional five extra wells.The contract value for drilling the wells is approximately $150m and the cost for the optional wells are not included in the estimated value.Equinor drilling and well operations senior vice president Erik Kirkemo said: “Deepsea Atlantic drilled the Johan Sverdrup phase 1 wells with excellent results, so we are pleased to secure the rig for phase 2 as well.“The rig is already on a continuing contract with Equinor, and our ambition is to keep it busy until Johan Sverdrup phase 2 comes on stream at the end of 2022.”Equinor is the operator of the Johan Sverdrup field developmentThe second phase of the development involves construction of a subsea production system, reconstruction of the existing riser platform as well as a new processing platform, which will house a converter unit receiving power from shore.The platform will distribute power to other fields on the Utsira High: Edvard Grieg, Ivar Aasen, Gina Krog and Sleipner.Equinor said that the four existing platforms on the Johan Sverdrup field are already receiving power from shore.The firm said that the second phase development will increase the production capacity of the field from 470,000 to 690,000 barrels per day on plateau.The licence partners include Equinor as the operator, Lundin, Petoro, Aker BP and Total.In October last year, Equinor and its partners started production from phase 1 of the NOK124bn ($13.63bn) Johan Sverdrup project in the Norwegian part of the North Sea.At peak production, the field is expected to account for almost a third of all oil extraction on the Norwegian continental shelflast_img read more


Airbnb and 23andMe are teaming up to popularize genealogical travel


first_imgWhether it’s another neighborhood within the city you’re from or a trip to a distant land, connecting with your roots can be an enriching experience, and with the help of Airbnb and 23andMe, you can now plan a trip as unique as your DNA. The rise in popularity of genealogical travel is also prevalent on Airbnb. Since 2014, the number of passengers using Airbnb to track their roots has increased by 500 percent. This type of travel is most often chosen by users between the ages of 60 and 90. The most popular destinations for genealogical travel are places known for their immigration history such as the US, Canada, Australia, China, the United Kingdom, France, Korea, New Zealand, Taiwan and Brazil. Learning about origins is a key reason why people opt for genetic testing like the ones offered by 23andMe. As many as 53 percent of users said they opted for the test because they want to learn more about their ancestors and the origins of their family. The rise of genealogical travel “At Airbnb, we believe that authentic travel experiences help connect with local culture and create a sense of belonging wherever you are in the world. And is there a better way to do that than traveling to the destination you come from? We are proud to announce that we have partnered with 23andMe to make it easier for travelers to plan trips that are as unique as their DNA.Said Joe Gebbia, director and co-founder of Airbnb. “Collaborating with Airbnb provides our clients with an exciting opportunity to connect with their ancestors through deeply personal cultural and tourist experiences”, Said Anne Wojcicki, CEO and co-founder of 23andMe. With the rise of home genetic testing and analytics, such as that offered by the 23andMe platform, it has never been easier to learn about one’s origins, which in turn has contributed to the growing trend of so-called “genealogical travel”. People around the world travel to connect with their ancestors, which is why Airbnb and 23andMe team up to make it easier to organize this type of travel. Both companies will integrate genealogical travel into their services. When a user receives a report of their origin on the 23andMe platform, they will have the opportunity to search through Airbnb for private accommodations and experiences in their ancestral countries. For example, if the user of the 23andMe service is originally from southern Italy, he can look for private accommodation in Apulia and explore his ancestors in more detail from there. Or someone with Mexican roots can find experience in Ciudad de México to learn ancient techniques of using natural colors that are part of his heritage. Also, special genealogy planning pages are now in Airbnb’s range of services. It is this curiosity about the origin that has contributed to the rise in popularity of genealogical journeys around the world. According to a study from April 2019, commissioned by Airbnb, as many as 89 percent of Indians traveled to at least one country where they have roots, just like 69 percent of French and more than half of Americans.last_img read more


ST: new SDK makes motor-control design faster and easier


first_img Continue Reading Previous Digi-Key: compact power measurement tool for IoT applications from QoitechNext Parasoft: support for microservice-specific protocols and message formats STMicroelectronics has further simplified development of advanced, energy-efficient motor drives on STM32 microcontrollers by harmonizing the latest STM32 PMSM FOC Software Development Kit with the STM32Cube ecosystem. The move extends opportunities for engineers to build sophisticated drives for equipment such as air conditioners, home appliances, drones, building automation, industrial machinery, medical devices, e-bikes, and many others, without needing specialized experience.Building on previous generations of ST’s Field-Oriented Control of Permanent Magnet Synchronous Motors SDK, the new version 5.0 firmware libraries align with the STM32Cube Hardware Abstraction Layer and Low Level architectures, which eases development, customization, and debugging. In addition, free access to source code gives developers extra flexibility, control, and customizability.New with MC-Workbench version 5.0, the Graphical User Interface leverages the STM32CubeMX workflow to set up the project, configure microcontroller peripherals, and generate initialization code automatically. It also lets users monitor and change control loop parameters in real time, as they develop or debug their projects.A rich selection of algorithms are included implementing popular PMSM-control techniques such as Maximum Torque Per Ampere to maximize efficiency and handle varying load conditions. Flux-Weakening control for extended speed range and feed-forward control for enhanced stability at high speeds are also included. Further features include “start-on-the-fly” to ensure smooth drive insertion when the rotor is already turning, which is often needed for outdoor fans such as in air conditioners or smoke extractors.Users can take advantage of proven, powerful SDK features including the Motor Profiler, which helps characterize most aspects of a motor quickly by automatically detecting the electrical parameters (stator resistance (Rs), inductance (Ls), and motor-voltage constant (Ke)), as well as mechanical friction and inertia. A variety of flexible motor-control strategies are also supported, including current sensing with single- or triple-shunt or isolated current sensors (ICS), rotor-position detection using encoder or Hall sensors, or sensorless control. The SDK also supports dual-motor applications, leveraging the rich analog features and multiple motor-control timers integrated in many STM32 variants.Share this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Chips & Components, Tools & Software last_img read more
