关于客户
扎库姆开发公司 (ZADCO) 是一家领先的石油公司,代表阿布扎比国家石油公司 (ADNOC) 以及 ADNOC、埃克森美孚和日本合资企业的股东开发世界第四大油田上扎库姆油田石油开发有限公司 ZADCO 致力于以安全、高效和对环境负责的方式管理上扎库姆油田。当一艘船舶与油田正在运行的井口平台相撞时,该公司面临着重大挑战,导致石油生产停止并威胁到平台的结构完整性。 ZADCO 的主要目标是快速评估和修复平台,以最大程度地减少损失并确保安全启动,同时证实事故及其造成的损失以提出保险索赔。
挑战
当一艘 1,600 吨级的船舶与位于阿拉伯联合酋长国阿布扎比近海的上扎库姆油田正在运行的井口平台相撞时,扎库姆开发公司 (ZADCO) 面临着重大挑战。这次撞击威胁到了平台的结构完整性,导致平台强度损失了 6.6%。该平台能够承受撞击后的季节性风暴,但只能支持直升机着陆和轻型船只停靠。由于石油生产暂停直至可以进行修复,ZADCO 的任务是快速评估和修复平台,以最大程度地减少损失、确保安全启动并避免环境污染。该公司还需要证实事故及其造成的损失才能提出保险索赔。该平台的结构分析因多种因素而变得复杂,包括缺乏用于所需分析的当前 SACS 模型、用于模拟影响的船速数据不可靠,以及结合非线性土桩相互作用建模的困难非弹性结构。
解决方案
ZADCO 决定使用各种 SACS 模块在内部进行快速、迭代的船只撞击分析。其中包括用于平台建模和载荷应用的 SACS Precede、用于桩和土壤特性建模的 SACS PSI,以及用于非线性船冲击分析和参数编码以及结果验证的 SACS Collapse。 SACS Collapse 模块中进行的非线性船舶碰撞分析有助于准确模拟平台的碰撞后行为和损坏的扩散。 ZADCO 进行了线性静态就地分析,以评估撞击造成的损坏,并验证受损平台的主要构件和桩在一年的风暴事件中是否安全。该团队还进行了详细的凹痕测绘以及海底和上部检查。通过使用 SACS 进行影响分析,ZADCO 能够优化检查范围,并将注意力集中在需要更详细审查的关键海底节点上。优化的检查范围和时间表允许在天气条件规定的狭窄窗口内进行工作。

Airport SCADA Systems Improve Service Levels
Modern airports are one of the busiest environments on Earth and rely on process automation equipment to ensure service operators achieve their KPIs. Increasingly airport SCADA systems are being used to control all aspects of the operation and associated facilities. This is because unplanned system downtime can cost dearly, both in terms of reduced revenues and the associated loss of customer satisfaction due to inevitable travel inconvenience and disruption.

IoT-based Fleet Intelligence Innovation
Speed to market is precious for DRVR, a rapidly growing start-up company. With a business model dependent on reliable mobile data, managers were spending their lives trying to negotiate data roaming deals with mobile network operators in different countries. And, even then, service quality was a constant concern.

Digitize Railway with Deutsche Bahn
To reduce maintenance costs and delay-causing failures for Deutsche Bahn. They need manual measurements by a position measurement system based on custom-made MEMS sensor clusters, which allow autonomous and continuous monitoring with wireless data transmission and long battery. They were looking for data pre-processing solution in the sensor and machine learning algorithms in the cloud so as to detect critical wear.

Vehicle Fleet Analytics
Organizations frequently implement a maintenance strategy for their fleets of vehicles using a combination of time and usage based maintenance schedules. While effective as a whole, time and usage based schedules do not take into account driving patterns, environmental factors, and sensors currently deployed within the vehicle measuring crank voltage, ignition voltage, and acceleration, all of which have a significant influence on the overall health of the vehicle.In a typical fleet, a large percentage of road calls are related to electrical failure, with battery failure being a common cause. Battery failures result in unmet service agreement levels and costly re-adjustment of scheduled to provide replacement vehicles. To reduce the impact of unplanned maintenance, the transportation logistics company was interested in a trial of C3 Vehicle Fleet Analytics.

3M Gains Real-Time Insight with Cloud Solution
The company has a long track record of innovative technology solutions. For example, 3M helps its customers optimize parking operations by automating fee collection and other processes. To improve support for this rapidly expanding segment, 3M needed to automate its own data collection and reporting. The company had recently purchased the assets of parking, tolling, and automatic license plate reader businesses, and required better insight into these acquisitions. Chad Reed, Global Business Manager for 3M Parking Systems, says, “With thousands of installations across the world, we couldn’t keep track of our software and hardware deployments, which made it difficult to understand our market penetration.” 3M wanted a tracking application that sales staff could use to get real-time information about the type and location of 3M products in parking lots and garages. So that it could be used on-site with potential customers, the solution would have to provide access to data anytime, anywhere, and from an array of mobile devices. Jason Fox, Mobile Application Architect at 3M, upped the ante by volunteering to deliver the new app in one weekend. For Fox and his team, these requirements meant turning to the cloud instead of an on-premises datacenter. “My first thought was to go directly to the cloud because we needed to provide access not only to our salespeople, but to resellers who didn’t have access to our internal network,” says Fox. “The cloud just seemed like a logical choice.”
