From the laser scanner to office in near real time

To move gas safely and reliably to the end consumer, the Netherlands has a high-quality gas transportation network. For undisturbed gas delivery, it is important that the network is always in excellent condition. Therefore, Gasunie, a European transmission system operator that provides the transport of natural and green gas in the Netherlands and the northern part of Germany, performs daily management and maintenance work to the main gas transportation network and to the regional gas transportation network.

The network in the Netherlands includes:

• 12,500公里的管道
• 3,000个阀门时间表
• 80测量和控制站
• 1,000 gas receiving stations
• 13 compressor stations.

在执行维护和更换期间，向最终客户的天然气传递。因此，造成尽可能少的不便是一个挑战。因此，Gasunie首先对管道进行了详细的设计。根据设计，新组件是预制的，因此在现场的安装工作需要尽可能少的时间。

结合多个徕卡呈规则的解决方案make laser scanning data available directly from the field to the customer and subcontractors, Gasunie can now save time and money with their re-designed Leica HDS workflows. Before integrating Leica Geosystems solutions, the time to deliver the as-built situation took quite long – now, a precise as-built model is ready within 24 hours.

The mix and match solution

为了加速和改善整体流程，使用3D激光扫描与Advin咨询和工程公司结合进行了飞行员。已经审查了工作过程，并通过使用Leica Jetstream软件来简化点云访问和超高速度渲染，在数据处理中采取了创新的步骤。

在设计，零件的预制和运输之后，将在现场组装新的安装。使用Leica Viva GS16 GNSS智能天线和带有Leica Captivate Software的CS35平板电脑链接的Leica Nova MS60多稳态检查此安装。在迷人的软件中，检查表面应用程序会探讨模型和构建情况之间是否存在偏差，并将确定新情况是否符合Gasunie的要求。

The entire installation is mapped either with the MultiStation or with a Leica ScanStation P40. This measurement is processed and checked in the field and uploaded directly to JetStream server via a mobile 4G connection on the CS35.

“The system Leica Geosystems has developed fits optimally to optimise our workflows. From the design to the final stage of a construction, this method of working reduces time and, therefore, saves money. In particular, the saved point cloud as asset information during the construction phase may become useful many years later. We are furthermore capable to scan brownfield assets and transform this to real 3D-asset information with new (future) functionality,” said Sijbrand Stratingh, senior pipeline engineer at Gasunie.

Benefiting from the industry - leading point cloud project server

The use of JetStream server has a number of important advantages. The data is centrally available in the cloud so engineers involved can directly access the data. Because the point cloud is available online, Gasunie can also access this data directly via TruView Global and/ or JetStream viewer. The firm can then use the point cloud for discussions using digital reality, making better informed decisions if needed.

Jetstream中的Smart Point Cloud技术允许通过在线连接毫不延迟查看和使用数据，而不会缺少任何细节。点云只有一个版本，因此只能进行一个备份。不必要的副本属于过去。

选定的选择必须正确

Thanks to Leica Geosystems combined solutions, the 3D design generated with the point cloud can seamlessly be adapted to the as-built situation. Gasunie no longer has any need to create a completely new as-built drawing from scratch. An update of the 3D-model is sufficient.

“We always strive to work with state-of-the-art hardware and software that can provide the best solution to our customer. The choice for Leica Geosystems, a reliable supplier of highend equipment, was a clear one. When we really have a problem, Leica Geosystems immediately provides a solution,” said Jeffrey den Ridder, surveyor at Advin. “After measuring the project, the excavated pit is replenished immediately with soil. The measurement must therefore be carried out as efficiently as possible and there is certainly no time for delays caused by defective equipment or technical failures.”

在完成了这些首次测试之后，Gasunie通过3D激光扫描和通过Autodesk®AutoCAD®Plant3D在云中的Jetstream通过Jetstream即时在线共享数据的工作流程非常积极。
