Marine 3D Laser Scanning & Modelling Survey
Marine 3D Laser Scanning & Modelling Survey Summary:
3D Laser scanning & surveying for Naval Architects & Marine Engineers – Ship navigation, retrofit, refurbishment, renovation, change of use, insurance & 3D navigation models.
Utilising both new and traditional techniques, Severn Partnership has the skills and experience to survey and CAD model a wide variety of marine vessels in any environment. Our 3D Laser Scanner is ideally suited to quickly and safely survey complex and intricate details on-board any ship or on any off-shore structure. The data from the laser scanner can then generate both 2D and 3D CAD plans, elevations & sections, which can be used for many different applications.
Why 3D laser scanning?
High speed, high accuracy, high detail, modelling the reality of the ship as it scans. This survey technique captures a massive volume of survey data safely with reflectorless measurement, ready for post processing back in the office. Scanning should be considered when accurate as built plans are required to avoid any design or retrofit problems further down the line – saving wasted time and cost.
We process the resulting point clouds in Rhino & 3D Studio Max to create highly accurate and detailed plans, sections and 3D models. Ship Hulls are ideal for laser scanning as they change in shape and section throughout the vessel – this surface can be rapidly modelled from scan data to create a true representation of the hull for structural analysis, naval architects and design teams.
Shipping and Marine 3D laser scanning and modelling applications include:
- Traditional Ship Surveys & Offset Survey Reports
Creation of 2D CAD ship surveys using both traditional surveying techniques and 3D laser scanning. Using this technique, we can rapidly and accurately model the complex shape of hull surfaces for shipbuilders, hull shape fairing and repair purposes. We can also create geometric and offset survey reports for establishing base points, GPS and heading calibration.
- Ship retrofit, refurbishment & structural alteration
Any alterations can be planned before, monitored during and analysed after using Laser Scanning and 3D modelling techniques. We have scanned for changes to the superstructure, fitting of new equipment, amendments to lifting arms and verifying storage spaces prior to loading. We can also accurately model piping and other on-board plant to allow accurate ‘fit first time’ design of retrofit plant.
- Accident and Legal Investigations
3D Laser scanning and 3D modelling can capture a 3D image of an accident for use in legal investigations. For more information see our Legal & Insurance Investigation page. We have also scanned for deformation of structural steel members & lifting arms for proof needed in insurance claims. We also have high accuracy Leica robotic total stations for verifying scan data on bent, deformed and broken equipment – the same service we carry out for the HSE (UK Health and Safety Executive).
- Change of use or ‘re-purposing’
Our case study of the Jan Steen shows how scanning is required prior to refit to plan and design plant & steelwork and after structural changes have been carried out to have an as built model. This survey also ensures the ship can be put back to it’s original state if being leased for a period of time – sometimes years. This 3D data can also be used to assess proposed designs for structural integrity and sea going stability.
3D models can be used for Computational Fluid Dynamics (CFD), Water flow, Finite Element Analysis (FEA) and within other Computational Analysis tools.
Damaged, twisted or collapsing structures can be monitored using detailed 3D models.
3D models and visualisations can be used in promotional campaigns, media releases or simply to impress clients.
- Archiving of Heritage Vessels and Structures
The keeping of 3D historical records can help specialists analyse marine vessels and structures better and help in restoration projects. Complicated uneven shapes and geometry can be quickly and accurately recorded prior to extracting 3D and 2D data for heritage purposes.
We can create deliverables for AutoCAD, Autodesk, SketchUp, Microstation, Cyclone, Pointools and many more.
