Laser Scanning and Survey

What makes laser scanning highly popular is the fact that it offers all the advantages of traditional surveying methods at a fraction of the cost. Laser surveying offers mainly 3 benefits compared to the traditional method. It shortens the surveying process, requires less materials of the surveyor and it provides data to clients, which can be repurposed without the help of the surveyor. The data appears as a “point cloud” which accurately represents the surface of the physical objects scanned. The laser captures exact size and shape and converts real world objects into 3D digital representation which can be further converted into Solid models, Polygon mesh models, Surface models, CAD models using various softwares that can be easily edited to customize your plans as required.

In modern engineering, Laser scanning is a highly versatile 3D scanning solution for a broad variety of applications such as complex plant environments, buidings and infrastructure, architectural and heritage sites, accident and forensic scenes and many more. Laser scanning is preferred nowadays by various organisations for the sheer simplicity it brings to the surveying process. Engineering and Construction sector are considered as two industries where laser scanning has had a huge impact in which spatial data gathering is a daily necessity. This is evident,especially in oil and gas industry, where all the planning/surveying of pipelines, is done by laser scanning.

Applications in Oil and Gas industry

The services offered under pipeline surveying generally falls into these categories - Aerial surveying, Land surveying and construction staking, and subsurface utilities engineering, create as built assets digitally. The major scanning services associated with each of these areas as follows.

Aerial Surveying

This includes surveying associated with pipelines, like digital terrain modeling,contour mapping, high altitude route selection imagery, low altitude engineering design industry, HCA study imagery, planning and profiling sheets and FERC support exhibits.

Land surveying and Construction Staking

Construction staking, planning and profiling sheets, well location staking, boundary surveying, right of way easements, preliminary center line and alignment staking services/applications are the services offered under land surveying and construction staking.

Subsurface Utilities Engineering

This includes services/applications for subsurface utilities engineering like CAD files preparation, nondestructive vacuum excavations, utility location and utility marking, relocation plans for utilities and visible surfaces feature surveys.

As-built Digitisation

Many onshore/offshore platforms require revamping,maintenance in order to increase the life time of the platform. Learn more on laser scanning services by visiting www.tech27.com
