Importance of Baseline Survey for Health Assessment of In-Service Equipment

The Definition of Baseline Survey

An initial survey is carried out at the start of a project to gather data on the condition of an area. In Brown / Greenfield projects, it refers to the collection of significant vitals, especially thinks of stationary equipment. This is done before the start of any process the equipment/project is intended for so that no process parameter may affect its basics.  

The Concept of the Baseline Survey

The basic concept of a baseline survey is to establish a fixed reference point that may be used for comparison purposes later on. In commercial business, the success of any project or product is measured against a forecast/ budgeted number for revenue, expense, or any other variables.

Here, the context of asset integrity may be thickness gauging, vibration, sound, or any other parameter likely to deteriorate over time.

The Objective of the Baseline Survey

The core purpose of a baseline is to analyze/evaluate the performance of a project by establishing the difference or changes that have occurred between the start and the mid- or any specific point in the project life cycle. However, baselines can also be used for other purposes, as the survey data provides valuable information.

The Importance of Collecting Baseline Data

The significance of gathering baseline data the goal of these baselines is to evaluate the program’s effectiveness and to make evaluations before and after the program’s introduction. In mechanical projects where rolled steel sheets, plates, or piping are involved, it is critical to have its thickness at the time of rolling as most rolling mills do it on the negative tolerance for production benefits.

Therefore, any object rolled in negative tolerance may deceive you if its nominal or design thickness is considered the initial value to observe the change.

Hence, in the absence of actual baseline data, it’s difficult to estimate any real-time changes or to demonstrate the correct corrosion allowance and remnant life later on, so it’s highly recommended to secure baseline information whenever possible.

Advantages of the Baseline Surveys

Depicts a clear picture of the intended purpose of capturing the baseline data, which allows the working team to study as accurately as desired. The comprehensive plan outlines the resources needed during the project’s development.

Allows deterioration to be measured and reported accurately.
