Interferences and collisions between components or objects (such as piping) can cause project delays and increase costs. Intertek 3D laser scanning services help detect these clashes before they happen.
Intertek is a global leader in the provision of Dimensional Control and 3D Laser Scanning surveys. One of the many benefits of 3D laser scanning is the ability to conduct clash detection surveys. Intertek is at the forefront of clash detection using the latest advancements in hardware and software to run simulations and test rotating interfaces. Clash detection is the process of looking for potential clashes (interferences, collisions) between components or objects prior to their installation or fabrication. It is a process used in many different industries to ensure the smooth installation of components with minimal down time or re-work required for the parts to fit.
Examples of where it is used include the oil and gas industry for refineries, offshore facilities, FPSO's (floating production storage and offloading vessels) or anywhere else piping is used. Figure 1 below is an example where piping engineers are working on an existing facility and adding in some new pipe runs and equipment. They need to know if the design will clash with any existing piping and components. Often these plants won't have up to date drawings or in some instances any drawings at all! By accurately capturing the as-built situation with 3D laser scanning the engineers can see the design in its intended location and also run a clash check routine against their design. Any clashes where a design element touches an existing element will be detected and reported therefore enabling the piping engineer to adjust the design and ensure smooth installation first time.

Intertek is a global distributor for the LFM suite of laser scan processing software. This software enables us to easily integrate the laser scan data into all the major CAD packages using plug-ins. We facilitate this for clients who wish to view data in their own native CAD packages to streamline the process or conduct clashing and reporting ourselves. The images below show the LFM server plug-in in action within Autodesk's AutoCAD.
