从激光扫描仪到实时的办公室

为了安全可靠地将天然气移至最终消费者，荷兰拥有高质量的天然气运输网络。对于不受干扰的气体输送，网络始终处于良好状态非常重要。因此，欧洲传输系统运营商Gasunie在荷兰和德国北部提供天然和绿色天然气的运输，他向主要天然气运输网络和区域天然气运输网络进行日常管理和维护工作。

The network in the Netherlands includes:

• 12,500公里的管道
• 3,000 valve schedules
• 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。

Gasunie结合了多个Leica GeoSystems解决方案，这些解决方案使激光扫描数据直接从现场到客户和分包商，现在可以通过重新设计的Leica HDS工作流程节省时间和金钱。在整合Leica Geosystems解决方案之前，提供了很长时间的时间花费了很长时间 - 现在，在24小时内准备好了一个精确的AS构建模型。

混合和匹配解决方案

To accelerate and improve the overall process, a pilot has been conducted in combination with Advin advisory and engineering firm using 3D laser scanning. The working process has been reviewed and innovative steps have been taken in the data processing by using Leica JetStream software for simplified point cloud access and ultra-high speed rendering.

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.”

After completing these first tests, Gasunie is very positive about the workflow through 3D laser scanning and instant online sharing of data through Jetstream in the cloud with Autodesk® AutoCAD® Plant 3D.
