Laser Scanning Team Tackles Refinerys Demanding Documentation

加利福尼亚州大型炼油厂的领先工程师是世界上最大的石油公司之一的一部分，面临在短时间内升级流体催化裂化单元的挑战。

Having an accurate, current as-built of the existing facility was crucial to ensuring installation of the new unit without rework or project delays, but the complete dataset would need to be provided in just four weeks. The traditional approach of using pocket tape measures and asymmetrical sketches was out of the question.

Believing that 3D laser scanning was the only conceivable way to gather accurate and comprehensive plant documentation in such a short period, the engineer contacted F3 & Associates, a company that he knew was an expert in 3D scanning and modeling. Would they be able to help?

Technology, Teamwork and Creativity Make It Happen
使用高分辨率扫描和照片提供最富有的数据集，以促进最准确的规划。

即使在3D激光扫描仪的帮助下，F3＆Associates的团队也知道他们必须创造出一种满足截止日期的方法。“我们为能够快速回应而自豪，无论要求起初多么不切实际，都可以似乎是多么不切实际的问题，”肖恩​​·芬恩，校长，F3＆Associates说。“在这种情况下，我们不得不凝聚一个通常需要两个月的项目的项目。”

为实现目标，该团队创建了一个战略工作流程，使用三个徕卡高清测量（HDS）激光扫描仪同时工作。该公司已经拥有Leica Scanstation C10，每秒捕获高达50,000点，距离高达300米;和Leica Scanstation P20，其捕获每秒高达100万积分，可达120米。自时间是本质的，该公司租用了一份Leica ScanStation P20激光扫描仪，并使用了两个高速扫描仪来捕获大多数数据。在需要远程，高度高度扫描的领域，该团队使用其Leica Scanstation C10。

“两种扫描仪类型的组合很大，因为我们可以在远程扫描上获得45分钟的C10，而P20S在指定的高分辨率要求下捕获了五个扫描，加上拍摄照片，”芬兰说。使用高分辨率扫描和照片提供最富有的数据集，以促进最准确的规划。

来自F3和Associates的五个专业人士编制了数据，有些人在扫描仪之前进行测量，以提供地面控制，而其他人则操作扫描仪。由于团队成员在测量和扫描上进行了交叉训练，因此他们有一些灵活性地帮助互相帮助，以确保不会发生瓶颈。例如，如果扫描的员工赶上了调查机组人员，他们就会缩短扫描并协助测量。

The Safer Solution
而团队能够获取更好的备用ion more quickly compared to traditional documentation methods, they also benefited from increased safety. Without laser scanning, they would have needed to use scaffolding and man-lifts to access hard-to-reach areas, but the Leica ScanStation P20 and C10 can document everything from the ground. In addition, because the data collected enables plant managers to plan installations methodically, it minimizes the amount of time that people have to spend in the plant. It's not necessary, for example, to revisit the plant to fill in gaps in the data because the data the P20 collects is so rich. Finn notes, "The less time you spend in the facility, the safer the project."

保持工作流程简单
Leica ScanStations are the standard in the petrochemical industry, but Finn said he also chose to use them because of the workflow simplicity. Once they captured the data, F3 & Associates downloaded it into the Leica Cyclone software, which allowed them to register the high accuracy point clouds quickly and easily. The associates then provided the refinery with a high resolution registered point cloud with photographs, as well as 3D prints for strategic areas to help stakeholders visualize the plant.

节省了巨大的时间......还有更多
在过去，他们将从一个漫长的购物项目开始记录。

使用诸如口袋磁带和剪贴板等传统工具，这一规模的项目将大约六个月。Finn估计，使用Leica Geosystems的激光扫描仪，加上他们的创造性工作流程，减少了一个月的文档时间。然而，他补充说没有激光扫描仪，“我不确定它甚至可能是可能的。”

在过去，他们将从一个漫长的购物项目开始记录。然后，他们会踏上，例如，管架高度，锚螺栓和关键结构，以显示工程师在哪里开始和在哪里结束。然而，挑战是从点A到Poile B.“你怎么会在那个管道上途中？你会错过什么？”芬恩说。“通过激光扫描，您可以制造管道并了解它需要的路线，所需的角度点以及触摸点的位置。

Laser scanning allows you to build things with more confidence." And, of course, the engineers could see it all on their computers from the comfort of their offices.

由于炼油厂在短短几周内获得了如此丰富的信息，因此他们能够在数据收集中省钱，并准确规划新的催化裂化单元的设计，建设和安装，从而避免不必要的延迟和停机时间。
