Plain sailing with 3D plant design

大多数乘坐海洋航行的乘客通常不知道艰苦的劳动，以建造和维护游轮。用激光扫描生成的3D建模和建筑信息建模（BIM）通过提供详细的数字蓝图，从而减轻了大多数泰坦尼克号任务，从而提高了导航期间的生产率，减轻了改造和改善维护。

时间是金钱，尤其是在运输和海上行业中。在维修和改造大型船只时提高生产率至关重要，因为停止商业业务是船东的总财务损失。为了最大程度地减少在码头上花费的时间，NautiSCAN3D，专门从事3D建模和测量的公司，surveyed a 288-metre-long passenger ship。这项调查帮助建筑师检查生产冲突并计划洗涤器系统的改造。

Scrubber systems are a diverse group of air pollution control devices. The scrubber system surveyed by NautiSCAN3D consisted of a steel tower on the ship funnel where sea water is injected to clean exhaust gas from Sulphur Oxides (SOx) and nitrogen oxides (NOx). This system helps shipping companies to be compliant with the International Convention for the Prevention of Pollution from Ships (MARPOL) established by the International Maritime Organisation (IMO).

所有的手放在桌上

Laser scanning collects all dimensional data to create 2D drawings, 3D models and BIM models. Elevations, sections and floor plans can all be converted into 3D models, 2D drawings or BIM-compatible formats to enhance the productivity of any retrofit work, such as adding new parts or replacing Heating, Ventilating and Air Conditioning (HVAC) equipment.

In association with Damen Shiprepair Brest and Sofresid Engineering Brest, NautiSCAN3D surveyed the passenger ship to prepare the studies for replacing the scrubber of the ship. Using a徕卡P30 ScanStation, the survey captured the data of seven decks, the engine room compartment and the30米的漏斗套管of the cruise ship.

该小组在英格兰和马德拉岛葡萄牙岛之间的国际水域中获得了数据。尽管比斯凯湾的风和海浪，54 scans were collected in approximately five hours。扫描在将近两天内处理，注册并检查了质量控制。

“数据获取的准确性和速度是促使我们获取Leica Geosystems扫描仪的一些主要因素。设备满足我们的需求，技术支持的质量非常明显。扫描仪非常直观且易于使用 - 我们没有遇到任何问题，”said Henri Patou, manager at NautiSCAN3D.

Point cloud for plant

激光扫描有助于为旧的洗涤器系统的拆卸，新系统组装以及在工厂设计管理系统（PDMS）中创建详细的3D模型，以避免在拟合过程中进行任何交互，并创建了详细的3D模型。所有收集的数据均已在左撇子旋风中注册，并在Leica CloudWorxfor PDMS plug-in.

The virtual site within CloudWorx for PDMS helped the team to预测零件之间的任何相互作用在下一个干船坞中，并评估新设备的潜在构建和操作影响。专家创建了根据下的模型，检查了针对现有条件的拟议设计，并进行了关键的构造和制造质量分析，所有这些都直接在PDMS的CloudWorx中进行了。

“This way of working during navigation, without stopping the ship, saves precious time to work on the engineering part in advance, avoid surprises during the technical stop in the yard, and anticipates all clashes for the operation. With the new systems installed smoothly on board, this project was a success,”帕图说。

可能性的海洋

Laser scanning offers multiple applications for the design, build and retrofit of any vessel. The capture of environments in 3D allows experts todetect any deficiencies in an accurate and safe way。除了翻新外，BIM模型还允许专业人员实时协作，从大规模到详细区域访问，以满足紧迫的物流海上和陆上。

With the power and knowledge to leverage this technology, NautiSCAN3D can offer services in the maritime sector and the naval industry intervening at various stages of the lifespan of a ship. Laser scanning allows them tomeasure with millimetre precision the geometry of parts, such as moulds, demoulded parts, primary forms, and appendagesto:

• 为稳定研究或安装创建形状和设计计划
• Generate as-built plans
• 协助任何元素的组装或拆卸，例如浮子，链接臂和舱壁
• 执行几何形状和变形分析的控制
• 在现场监视中进行。

The quest for increased productivity pushes the boundaries of technology. Mirroring the reality in 3D and CAD environments has revolutionised productivity for architects, engineers, plant managers and other professionals who now can plan, build, maintain and renew any structures with unforeseen speed, precision and accuracy.
