Pre-Commissioning – Staging
Demonstrated Value When It Matters Most
Table of Contents:
The value B&W provides to its customers is simple—properly planning out and executing pre-commissioning activities and pre-commissioning cleaning means major cost savings and staying on schedule.

As the oil and gas industry continues to grow, the demand for safe, high-quality products being delivered to the market grows with it. To meet this demand, refineries and petrochemical plants are increasing output by expanding existing production facilities or building new ones.
Before startup, it’s essential that all newly constructed systems on these projects are cleaned and tested properly. That’s where pre-commissioning comes into play.
What is Pre-Commissioning?
Pre-commissioning refers to the process of testing, cleaning and verifying the functionality of equipment and systems prior to their operation at your plant.

Why Is Pre-Commissioning Important?
Cost Savings
Failing to effectively plan and execute a project’s pre-commissioning and commissioning cleaning can significantly increase project costs and delays. By conducting effective cleaning prior to startup, you can prevent costly downtime and not repeat activities during commissioning.
Total Investment Value Savings of 1-5%
Consider pre-commissioning cleaning services during the design phase of your project, and you could save an estimated 1-5% of its total investment value. It’s much more cost-effective to clean equipment once the right way than to repeat the cleaning process further down the line.
Safety
It may be difficult to believe, but here are a few objects the B&W team has found left in piping systems and turbines while preparing to perform pre-commissioning:
- Pebbles
- Ladder sections
- Scaffold legs
- Hard hats
- Grinding wheels
- Welding rods
With the high pressures involved in steam blowing, AquaLazing and other pre-commissioning activities, you don’t want any foreign objects obstructing your facility’s systems. Even one pebble can do a lot of damage to a piping system when subjected to high pressure. That’s one of the many reasons why pre-commissioning is essential.

Pre-commissioning cleaning services ensure the safety of personnel, equipment and the environment. The process confirms that all equipment and systems are clean, functioning properly and ready to operate safely.
Pre-commissioning companies identifying and correcting any issues caused by nonfunctioning or contaminated equipment before a facility’s startup is essential, as this can prevent accidents, equipment failures and increased downtime.
Efficiency and Reliability
Effective pre-commissioning can also improve your facility’s efficiency. Project pre-commissioning ensures that your facility operates at its optimum level, verifying that all systems are clean, functioning properly and can operate continuously without interruptions. Systems that are cleaned effectively from the start will require less maintenance down the line.
