- Increasing capacity
- Improving process quality
- Maintaining aging plant assets
- Complying with environmental requirements
Project savings can manifest themselves in the following manners as well:
- Reduced shut-down, turn-around, or outage time
- Redeemed production volumes
- Fewer field installation fit-ups / weld connections and post-weld heat treatments
- Elimination of potential field interference problems
- Reduced design and fabrication costs for re-engineering and re-work
|
Greatest savings are realized during the detail engineering and construction phases of a project. The increased
accuracy of data collected by 3D laser scanning measuring methods reduces the risk of re-work or re-engineering
caused by a low level of front-end engineering. |
Accurate as-built drawings are an essential to estimate the scope and cost of a retrofit project during front-end engineering
stages. 3D laser scanning technology offers an ideal solution for capturing existing geometry and physical relationships
as a basis for front-end engineering when the following situations arise: |
- Drawings are unproven, inaccurate, inadequate, or unavailable
- The volume of field data required would be cost prohibitive to collect using conventional measuring methods
- The field data is physically difficult or unsafe to collect conventionally
- The allowable residual error is smaller than economically achievable by conventional methods
|
3D laser scanning can also help reduce the impact of re-work and re-engineering arising from a low level of front-end
engineering. 3D laser scanning can help provide viable solutions to challenges arising mid-project, and restore confidence
in achieving project goals, if the following situations occur during project implementation. |
- The accuracy of legacy as-built drawings used becomes suspect
- Engineering documents are not yielding all required information
|
Confidence in the pre-engineering starting point has become diminished after time consuming site
visits and precarious field measurements.
