Pipeline Gauging & Filling (Flooding)

Pipeline Gauging is carried out to prove the dimensional quality of the internal diameter of the pipeline.

Pipeline Filling can be carried out by propelling pigs through the pipeline with water or free flooding with water (normally for smaller or unpiggable pipelines).

​

Hydrotesting 

​

A hydrostatic test is a way in which pressure vessels such as pipelines and tanks can be tested for strength and leaks following initial construction or repair works.

ACTION work closely with our clients to ensure that their specifications are followed, in line with common industry standards.

Pipeline Cleaning (Chemical)

​

Chemical cleaning is generally carried out in three distinct stages which all include filtration. 

1. Degreasing & Anti-scaling – Chemical Cleaning

2. Corrosion Inhibiting/Passivation

3. Biocide Washing

​

Pipeline Cleaning (Pigging)

​

While buildup in a pipeline can cause transmittal slows or even plugging of the pipeline, cracks or flaws in the line can be disastrous. A form of flow assurance for oil and gas pipelines and flowlines, pipeline pigging (using foam or gel pigs) ensures the line is running smoothly.

​

Dewatering & Air Blowing

​

Once hydro testing is completed on a system, the line requires to be dewatered and possibly dried to a negative Dew point to ensure no corrosion and contamination prior to start up. This involves pushing pigs through the pipeline propelled by a gas to remove the water prior to start-up. 

Filtration & Disinfection

​

Using filters and chemicals ACTION maintain/improve parameters of the selected medium being used for the precommissioning process, allowing for the re-use and ultimately safe disposal.

Flange Management

​

Providing integrity assurance through detailed tracking of each mechanical joint history from installation to final reinstatement, ACTION's flange management team maintain a database with individual ID's allocated to each joint along with certification. 

Leak testing

​

Once final reinstatement is completed, each system and/or sub system will be isolated depending on system rating or operating pressure. The Leak test will then be carried out based on 95% of operating pressure OR system PRV (Which ever is lower) 

​

Purging/Inerting

​

After Leak test completion, some systems require nitrogen purging and/or inerting prior to system start up to remove all oxygen that can be problematic for the process medium.
