Plain sailing with 3D plant design

大多数乘客航行在海洋常常是联合国aware of the herculean labour to build and maintain a cruise ship. 3D modelling and Building Information Modelling (BIM) generated with laser scanning have eased most titanic tasks by providing a detailed digital blueprint of a vessel, increasing productivity during navigation, easing retrofit and improving maintenance.

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, a company specialised in 3D modelling and measurements,调查了288米长的乘客。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 aLeica P30 ScanStation，调查捕获了七个甲板，机房隔间和30米的漏斗套管of the cruise ship.

该小组在英格兰和葡萄牙马德拉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，在大约五个小时内收集了54次扫描。Scans were processed, registered and checked for quality control in almost two days.

“数据获取的准确性和速度是促使我们获得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。收集的所有数据均已在左右旋风中注册，并在Leica CloudWorxfor PDMS plug-in.

PDMS CloudWorx中的虚拟站点帮助团队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PDM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。

An ocean of possibilities

激光扫描为任何船只的设计，建造和改造提供了多种应用。3D中环境的捕获使专家能够detect 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，从大规模到详细的区域访问，以满足紧迫的物流海上和陆上。

凭借能够利用这项技术的力量和知识，Nautiscan3D可以在海事领域提供服务，并在船上的各个阶段中介入海军行业。激光扫描使他们能够measure 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
• 生成肥大的计划
• 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.
