与3D植物设计的普通航行

作者：Renata BarradasGutiérrez

Most passengers sailing across oceans are often unaware 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.

Time is money, especially in the shipping and maritime industries. Enhancing productivity while repairing and retrofitting large vessels is crucial as stopping commercial operations is a total financial loss for ship-owners. To minimise time spent in the dock,Nautiscan3d, a company specialised in 3D modelling and measurements,调查了一艘288米长的客船. This survey helped architects to check for production clashes and to plan retrofit of a scrubber system.

洗涤器系统是一组多样化的空气污染控制设备。由Nautiscan3D调查的洗涤器系统由船舶漏斗上的钢塔组成，其中海水注入海水以清洁硫氧化物（SOX）和氮氧化物（NOX）的排气。该系统可帮助航运公司遵守国际海事组织（IMO）建立的预防船舶污染（MARPOL）的国际公约。

激光扫描收集所有维数据以创建2D图，3D模型和BIM模型。高程，部分和平面图都可以转换为3D型号，2D图纸或BIM兼容格式，以提高任何改装工作的生产率，例如添加新零件或更换加热，通风和空调（HVAC）设备。

与Damen Shiprepair Brest和Sofresid Engineering Brest合作，Nautiscan3D对乘客进行了调查，以准备更换船舶洗涤器的研究。用一个Leica P30扫描仪，调查捕获了七个甲板的数据，引擎室舱和30-metre funnel casing游轮。

The team acquired the data in international waters between England and the Portuguese island of Madeira. Despite strong winds and waves of the Bay of Biscay,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.

“Accuracy and speed of data acquisition were some major factors that drove us to acquire a Leica Geosystems ScanStation. The equipment meets our needs, and quality of the technical support is very appreciable. The ScanStation is very intuitive and simple to use – we haven’t experienced any issues,”Nautiscan3d的经理Henri Patou说。

Laser scanning helped to create a model for the disassembly of the old scrubber system, the assembly of the new system, and a detailed 3D model was created in a Plant Design Management System (PDMS) to avoid any interaction during fitting. All data collected has been registered in Leica Cyclone and as-built point cloud data was manipulated inLeica Cloudworx对于PDMS插件。

PDMS CloudWorx中的虚拟站点帮助团队anticipate any interaction between partsduring the next dry dock and assess the potential construction and operational impacts of the new equipment. Experts created the as-built model, checked the proposed design against the existing conditions, and performed critical construction and fabrication quality analysis, all directly within CloudWorx for PDMS.

“这种在导航期间工作的方式在不停止船舶的情况下节省了宝贵的时间来提前在工程部分上工作，避免在院子里的技术停靠期间感到惊讶，并预计所有运营的冲突。随着新系统安装顺利安装，该项目成功了，”said Patou.

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以准确且安全的方式检测任何缺陷. Beyond retrofitting, BIM models allow professionals to collaborate in real time, accessing from large scale to detailed area, to meet the pressing logistics offshore and onshore.

有了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用毫米精度测量零件的几何形状，例如模具，脱离零件，主要形式和附属物至：

• Create shape and design plans for stability studies or installation
• 生成肥大的计划
• Assist the assembly or disassembly of any elements, such as floats, link arms, and bulkheads
• Perform controls of geometries and deformation analysis
• Do in site monitoring.

寻求提高生产率的追求推动了技术的界限。反映3D和CAD环境中的现实已经彻底改变了建筑师，工程师，工厂经理和其他专业人员的生产力，他们现在可以以不可预见的速度，精确性和准确性来计划，构建，维护和续订任何结构。
