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。对于不受干扰的天然气输送，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方式，可每天管理和维护工作，向主要的天然气运输网络以及区域天然气运输网络。

The network in the Netherlands includes:

• 12,500 kilometres of pipeline
• 3,000个阀门时间表
• 80 measuring and control stations
• 1,000 gas receiving stations
• 13 compressor stations.

During the execution of maintenance and replacements, the delivery of gas to end customers continues. It is, therefore, a challenge to cause as little inconvenience as possible. For this reason, Gasunie first makes a detailed design of the pipes. Based on the design, the new components are prefabricated, so that the installation work in the field takes as little time as possible.

Combining multiple Leica Geosystems solutions that 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.

混合和匹配解决方案

为了加速和改善整体过程，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、预制和运输the parts, the new installation is assembled on site. This installation is checked using a Leica Viva GS16 GNSS Smart Antenna and a Leica Nova MS60 MultiStation linked to a CS35 tablet computer with Leica Captivate software. Inside the Captivate software, the Inspect Surface app looks at whether there are deviations between model and as-built situation and will determine whether the new situation meets the requirements of Gasunie.

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.

“系统Leica Geosystems已开发出最佳的开发，以优化我们的工作流程。从设计到建筑的最后阶段，这种工作方法减少了时间，因此可以节省金钱。特别是，在施工阶段，保存的点云作为资产信息可能会在多年后变得有用。此外，我们还能够扫描棕地资产，并将其转换为具有新（未来）功能的真正的3D资产信息。” Gasunie的高级管道工程师Sijbrand Stratingh说。

受益于行业 - 领先的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.

The smart point cloud technology in JetStream allows data to be viewed and used without delay via an online connection without missing any detail. There is only one version of the point cloud and, therefore, only one backup has to be made. Unnecessary copies belong to the past.

The selected choice when it has to be right

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.

“我们始终努力使用最先进的硬件和软件，这些硬件和软件可以为我们的客户提供最佳解决方案。可靠的高端设备供应商Leica Geosystems的选择是明显的。当我们真正遇到问题时，Leica Geosystems立即提供了解决方案。” Advin测量师Jeffrey Den Ridder说。“测量项目后，挖掘的坑立即用土壤补充。因此，必须尽可能高效地进行测量，并且肯定没有时间因设备有缺陷或技术故障而引起的延误。”

完成了这些第一项测试后，Gasunie对通过3D激光扫描和通过Autodesk®Autocad®Plant3D的云中的Jetstream进行了在线数据的工作流程非常积极。
