Recipe for Success: 3D laser scanning for tank inspections

Author: Wagner Manurung

检查45米高罐面粉的最佳方法是什么？并计算大量库存中的面粉？这些是印度尼西亚PT Wilmar的项目团队面临的挑战。该公司是Wilmar International Limited, Asia’s leading agribusiness group. Wilmar operates an integrated agribusiness model that encompasses the entire value chain of the agricultural commodity business, from cultivation, processing, merchandising to manufacturing of a wide range of agricultural products, including rice and wheat flour. It has an extensive distribution network covering China, India, five factories in Indonesia and a presence in 50 other countries and regions.

在此规模上加工农产品涉及在储罐和孤岛中存储大量农亚搏彩票手机版下载产品。这些巨大的船只的保养是一项严肃的生意。这些坦克是该公司的关键财务资源，并且遵守国际安全标准。在PT Wilmar Nabati印度尼西亚，项目团队必须定期检查所有地上储罐，向管理层报告指示结构完整性的测量结果。以前，坦克检查是耗时的手动过程。

更快的检查而没有任何妥协

PT Wilmar Indonesia希望找到一种方法，使坦克检查过程更有效。更快，但不需要更多的人力。一个新的解决方案不能损害数据的准确性或团队的安全性 - 理想情况下都可以改善两者。

Already a Leica Geosystems user in other parts of the business, PT Wilmar chose to implement laser scanning. The company equipped the project team withLeica RTC360激光扫描仪以数字扫描筒仓和旋风3dr用于数据分析的软件。RTC360 3D激光扫描仪的测量速率每秒高达200万点，并且具有先进的高动力范围（HDR）成像系统，可在两分钟内完成彩色3D点云。

亚博ag真人规律现实捕获已改变了检查。与手动检查相比，他们现在可以捕获有关每天15个坦克的信息，手动检查需要3至4天。这是惊人的4,500％的提高。

全面的数据捕获以满足法规

手动检查很耗时，因为要符合国际坦克检查标准（API 650/653），您需要准确收集多个数据点，包括直径测量，圆度，坦克的垂直度和内容的结算。这是衡量生产量的补充，这对业务来说是重要的信息。

By capturing a 3D image of the tanks, the RTC360 scanners collect this information within minutes, the project team can extract it from the point cloud. A PT Wilmar spokesperson explains, “This analysis process is done by the旋风3drsoftware which is dedicated for calibration and silo inspection according to international standards.”

Easy-to-use software reduces training time

Because the objective of the project to introduce 3D laser scanning was to improve efficiency, the new technology could not make extra demands on the team’s time. A spokesperson from PT Wilmar found the solution easy to use and training has been minimal, “Leica Geosystems products are easy to set up and operate, so it did not take much time for us to study.”

The lightweight portable laser scanners have had a positive impact on the way the team works. Fewer people need to be on site doing the inspections freeing up time to work on data analysis. PT Wilmar's spokesperson explains, “[We had a] limitation in human resources to do data processing. Having the RTC360 in use takes few people to do the fieldwork (only one or two) while the other team members can be processing the data in the office.”

提高安全性，生产中断更少

Previously, the need to physically take measurements could be disruptive in areas of the factory with active machinery. 3D laser scanning is a non-invasive technology that captures measurements from a distance. Nearby machinery doesn’t need to be turned off and there is no risk of contamination. This makes laser scanning both safer for the operator and more productive for the business.

As well as using the RTC360 for tank inspections, PT Wilmar's project team have been using them for stockpile calculations, where the ability to measure from a distance has been a real benefit: “We get accuracy on the calculation and it’s easy to proceed, so we have no issue anymore with high or large stockpiles. Previously, we used total stations and faced a difficult process in the field. Now, we are glad that we don’t necessarily need to climb the stockpile of the flour to measure the volume!.”

使用RTC360激光扫描仪和Cyclone 3DR软件进行坦克检查，这对于PT Wilmar Indonesia来说是成功的。不仅满足了提高效率的目标，而且3D扫描使项目团队更容易向管理层向管理层报告维护和汇编其年度审核。

PT Wilmar的发言人说：“它有助于启用简单的筒仓维护，将常规数据更改为3D数据，从而在捕获现场的每个捕获数据角度创建清晰的报告。最后，它有助于PT Wilmar管理层在3D数据中查看实际条件。管理团队现在不需要去现场检查工厂状况。”在3D扫描的数据丰富的输出中，所有内容都在那里。
