关于客户
FMC Technologies 是海底系统的全球市场领导者，也是石油和天然气行业技术和服务的领先提供商。他们通过陆上和海上钻井、完井和生产技术及服务帮助勘探和生产客户克服困难挑战，以提高回报。该公司以其应对复杂挑战的创新解决方案而闻名，特别是在海底石油和天然气设备的设计和制造方面。他们对价值工程和减少过度工程的承诺在他们解决问题的方法中显而易见。
挑战
FMC 技术印度列兵。 Ltd. 面临着设计能够承受高压和高温领域的海底石油和天然气设备的挑战。该设备必须符合 ASME BPVC VIII 第 3 部分的要求，该标准要求设备的累积损坏低于 1。石油开采深度的增加意味着海底组件的结构载荷要求不断增加，但也存在空间不足的问题。以及这些部件的重量限制。为了减少过度设计并促进价值工程，工程师需要可视化每个组件的损坏分布。然而，他们使用的 ANSYS Structural 技术没有绘制损坏图的方法。面临的挑战是使用 ANSYS 的脚本功能开发定制方法。
解决方案
FMC Technologies 使用 ANSYS Mechanical 或 Workbench 通过有限元分析 (FEA) 确定产品所经历的负载条件。他们开发了 ANSYS Mechanical 宏来根据 ASME BPVC VIII Division 3, Article KD 232.1 评估累积损伤。 ANSYS 参数化设计语言用于定制分析以提供损伤可视化。宏代码编写了一个附加的 .RST 文件，其中包含每个节点的 ASME 损坏值的基本节点值。评估了损伤值对部件的影响。如果需要改进产品性能，工程师会根据 .RST 文件中的损坏信息做出明智的决定。 ANSYS 后处理工具用于绘制损坏图并识别设计中不满足 ASME Sec 要求的区域。 VIII D3 标准。

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
