秘方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？并计算出巨大的库存中的面粉？这些是印度尼西亚PT威尔马项目团队的挑战。该公司是Wilmar International Limited，亚洲领先的农业综合企业小组。威尔玛（Wilmar）经营着一个综合的农业综合企业模型，该模型涵盖了农业商品业务的整个价值链，从耕种，加工，商品到制造各种农产品，包括大米和小麦粉。bob综合app下载它拥有广泛的分销网络，涵盖了中国，印度，印度尼西亚的五家工厂以及其他50个国家和地区的存在。

在此规模上加工农产品涉及在储罐和孤岛中存储大量农bob综合app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，坦克检查是一项耗时的手动过程。

更快的检查而没有任何妥协

PT Wilmar Indonesia希望找到一种方法来提高坦克检查过程的效率。更快，但不需要更多的人力。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高达每秒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。

Reality capture has transformed inspections. They can now capture information on 15 tanks per day compared to manual inspections, which take three to four days per tank. That’s a staggering 4,500% efficiency increase.

全面的数据捕获以满足法规

Manual inspection was time consuming because to meet international standards of tank inspection (API 650/653), you need to accurately collect multiple datapoints, including diameter measurements, roundness, verticality of the tanks and settlement of the contents. This is in addition to measuring the volume of production, which is vital information for the business.

通过捕获储罐的3D图像，RTC360扫描仪会在几分钟内收集此信息，项目团队可以从点云中提取它。PT Wilmar发言人解释说：“此分析过程是由旋风3dr根据国际标准专门用于校准和筒仓检查的软件。”

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，生产中断较少

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，从而在捕获现场的各个角度创建清晰的报告。最后，它有助于PT Wilmar Management在3D数据中查看实际条件。现在，管理团队无需去现场检查工厂状况。”在3D扫描的数据丰富的输出中，所有内容都在其中。
