The paper reviews the change of traditional routines to new technologies, by way of Laser Scanning, to allow Naval Architects, Engineers and Shipyards the ability to safely, efficiently and cost-effectively capture spaces within an As-Built structure and modify, update or change said structure. Downtime and budgetary concerns, human error, along with safety, are the driving forces for modifications to vessels throughout the Oil and Gas industry, with these advancements, jobs can be completed with these factors in mind and exceed expectations.

Traditionally, site surveys must be conducted onboard a vessel to measure and capture specific areas of modification. This creates a toll to surveyor and company – over and above the equipment that a surveyor brings with them, scaffolding, harnesses and Safety support personnel, to name a few, must also be introduced, instantly increasing the overall cost of a project, reducing manpower onboard and slowing down work flow. Subsequently, the surveyor is only capturing details of a specific area with 2-dimensional photos, sketches and basic measurements. In the following days, weeks and months, these notes are the only information available to recreate and discuss for the project. This paper reviews the current workflow for site survey and project development and shows proof how Laser Scanning reduces and minimizes human-error, safety, timelines and budgetary concerns.

This paper explores the advantages to Site Survey through traditional means and Laser Scanning; focusing on minimizing safety, timeline and budgetary concerns. A comparison of traditional means using measuring tapes, scaffolding and manpower and the FARO S150 Terrestrial Laser Scanner and a 1-man operator.

This paper seeks to answer the question: What will the effective cost savings, safety practices and efficiency be when using Laser Scanning, and subsequent 3-dimensional model, have on a project?

It is hoped this analysis and study will inform Naval Architects, Engineers, Shipyards and more about the usefulness, ease, efficiency and cost savings gained by using Laser Scanning on a project for the modification of an As-Built Structure.
