挑战

Grupo Especializado en Obras Marinas (GEOMSA) 是墨西哥湾管土系统的主要开发商，其任务是评估水下管道系统粘土沟槽中各种条件下的管道完整性。该项目的目标是增加周边地区的国内石油产量。该团队需要确定新的管道系统如何应对膨胀和横向变形，考虑路线的水平曲线、沟槽的不同宽度、管道上方的海底层数以及管道如何与粘土相互作用它被放置的环境。他们还必须考虑温度、横向变形和系统应力等变量，通过在沟槽内进行模拟来确定管道的逻辑和可靠的行为。

解决方案

为了应对这些挑战，GEOMSA 部署了 Bentley 的 AutoPIPE 来执行结构分析并准确建模管道的几何形状和土壤的特性。该项目分两个阶段进行。在第一阶段，工程团队使用 AutoPIPE 开发了一个 3D 模型，该模型利用项目的信息数据库来描述管道、连接件和阀门所需的材料类型。在第二阶段，设计团队输入规范和规定、设计因素、设计压力和温度以及弯头的弯曲半径。然后使用这些因素来计算系统如何与土壤相互作用。工程师在模型中操纵土管相互作用的参数来模拟沟槽宽度的变化。他们还进行了多次灵活性分析，以便团队可以获得粘土的应力结果和变形。

运营影响

The use of AutoPIPE led to significant benefits for GEOMSA. The application helped the engineering team reduce the time that it would have normally taken to modify how the piping system would interact with the soil, while also accurately representing gradual variations in the trench’s width. AutoPIPE also enabled the engineering team to create realistic designs that reduced the risk of the pipeline failing. The user-friendly application displayed the analysis to the project team in a fully graphical environment so that the results could be clearly understood by all stakeholders. This improved collaboration, and saved time and cost. AutoPIPE was also instrumental in allowing the project team to meet local and international regulations or codes. This capability allowed the engineers to feel confident that they were creating the safest pipeline system, reducing the risk of marine pipeline failure and the severe environmental impact on the surrounding area.

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.

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.

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.

Shell uses the IoT for pipeline monitoring

Oil company Shell wants to take advantage of an internet of things (IoT) connectivity solution to improve the company’s monitoring capabilities for its operations in Nigeria.

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.
