关于客户
贝克休斯是通用电气旗下公司（纽约证券交易所股票代码：BHGE），是全球第一家也是唯一一家综合油田产品、服务和数字解决方案的全流程提供商。该公司致力于提高客户的生产力、安全性和环境管理，同时最大限度地降低能源价值链每一步的成本和风险。 BHGE 在 120 多个国家/地区开展业务，将一个多世纪的经验与初创公司精神相结合，发明更智能的方式为世界带来能源。
挑战
BHGE 二次流与传热团队的任务是在燃气轮机设计过程中进行广泛的分析。该团队的工作范围包括估计整个涡轮机的二次空气需求、为发动机主要部件的热机械分析提供边界条件、支持热力循环性能的估计等任务。热设计过程的重点是组件的使用寿命和可靠性，这与控制局部温度和热梯度直接相关。此外，团队必须考虑所需的冷却质量流量和回流裕度 (BFM)，后者量化通过冷却组件壁吸入热气体的压力裕度。 BFM 的评估不是确定性的，而是应该以统计方式进行，考虑几何和热流体动力学边界条件的所有不确定性。因此，可以对组件故障进行概率评估，确定故障概率。
解决方案
BHGE 团队面临的挑战的解决方案是 GE 开发的 Flow Simulator。流体模拟器提供了一个智能 GUI，允许团队在后台上传发动机的横截面，从而提供模型及其结果的清晰概述。 GUI 还使团队能够直接在导入的横截面上执行测量，以实现快速模型设置。流量模拟器还包括一个大型一维元素数据库，适用于模拟整个燃气轮机二次流网络的所有特征。由于实现了许多相关性以及调整和实现自定义相关性的可能性，该软件非常灵活。流动模拟器还具有稳定、快速的求解器以及多次运行的快速设置，这对于模拟系统在不同工作条件下的行为或执行统计多次运行方法以实现稳健的设计至关重要。该工具已成功用于 BHGE 机组燃气轮机的分析，以及 NovaLT 系列最新燃气轮机的设计和验证过程。

Taking Oil and Gas Exploration to the Next Level
DownUnder GeoSolutions (DUG) wanted to increase computing performance by 5 to 10 times to improve seismic processing. The solution must build on current architecture software investments without sacrificing existing software and scale computing without scaling IT infrastructure costs.
Case Study
Remote Wellhead Monitoring
Each wellhead was equipped with various sensors and meters that needed to be monitored and controlled from a central HMI, often miles away from the assets in the field. Redundant solar and wind generators were installed at each wellhead to support the electrical needs of the pumpstations, temperature meters, cameras, and cellular modules. In addition to asset management and remote control capabilities, data logging for remote surveillance and alarm notifications was a key demand from the customer. Terra Ferma’s solution needed to be power efficient, reliable, and capable of supporting high-bandwidth data-feeds. They needed a multi-link cellular connection to a central server that sustained reliable and redundant monitoring and control of flow meters, temperature sensors, power supply, and event-logging; including video and image files. This open-standard network needed to interface with the existing SCADA and proprietary network management software.

Refinery Saves Over $700,000 with Smart Wireless
One of the largest petroleum refineries in the world is equipped to refine various types of crude oil and manufacture various grades of fuel from motor gasoline to Aviation Turbine Fuel. Due to wear and tear, eight hydrogen valves in each refinery were leaking, and each cost $1800 per ton of hydrogen vented. The plant also had leakage on nearly 30 flare control hydrocarbon valves. The refinery wanted a continuous, online monitoring system that could catch leaks early, minimize hydrogen and hydrocarbon production losses, and improve safety for maintenance.
