ROSEN offers a large spectrum of pipeline cleaning solutions gained in working together with our customers on many pipeline projects. Cleaning is a vital aspect of the integrity management of pipeline networks and is necessary at every stage throughout the life cycle of an oil, refined product or gas pipeline, from pre-commissioning, through commissioning, operations, and ultimately- during the decommissioning phase of the cycle.

Continuous development and innovation have ensured that our cleaning solutions are backed by robust service products and experienced service personnel.

With in-house expertise in sensor and data acquisition technologies ROSEN is the first choice for Intelligent Cleaning Solutions using our high quality electronic measurement instruments, data analysis software, and integrity management systems.

We recognize that each pipeline is different and cleaning needs vary depending on the operational purpose & stage of its life cycle.

 

Why Clean

The efficient operation of pipelines depends on 2 fundamental aspects. 1) the continuous transportation of the medium and 2) the maintenance of the internal diameter for optimal flow. To realize these essential aspects, pipeline cleaning plays a critical role by:

  • Avoiding build up and removing deposits from the line which can cause damage by abrasion or encourage under deposit corrosion
  • minimizing product contamination thus ensuring delivery of high quality product
  •  maintaining a clean surface onto which corrosion inhibitors can uniformly be applied perform most effectively
  • reducing pre-in-line-inspection (ILI) preparatory work for inspection services and thus increasing the likelihood of securing high quality data

In summary, not cleaning your pipeline can drastically effect the efficiency, safety, and reliability of the entire network. Foreign matter and buildup can damage the integrity of a pipeline, enhance the formation of corrosion and pipe thinning, and will almost certainly reduce throughput.  

The Clean Effect

The ROSEN Group is dedicated to the integrity of pipeline systems around the world, offering extensive services for the inspection of pipelines. Although a clean pipeline has many key benefits one is directly related to its further inspection. The success of each in-line inspection service largely relies on the cleanliness of the pipeline.

Inspections are affected by the state of a pipeline as:

  1. Debris can reduce signal penetration of the measurement technology, resulting in poor data quality
  2. Buildup can cause sensor liftoff, which in turn creates gaps or missing data & inaccurate measurements of wall thickness, anomalies & defects.

 

When Clean

The cleaning requirements for a pipeline during its life cycle are many and varied, depending on what stage in the life cycle it is in. The stages include:

  • Pre-Commission Cleaning: After construction and prior to commissioning of the new pipeline
  • Commissioning Cleaning & Service Preparation: Dewatering, drying, and conditioning
  • Operational Cleaning
  • Change of Service Cleaning & Preparation
  • Cleaning prior to the Cessation of Production (COP)
  • Decommissioning Cleaning prior to Abandonment, Recovery and/or Recycling

During any of these stages contaminates can collect within the line, if this material is not removed it can not only effect the efficiency of the line but perhaps even contaminate product or hinder corrosion inhibitors from performing properly.

Contaminates can vary from wax, scale, corrosion products, hydrates, emulsions, produced sands, and even water. In fact, the best time to clean a pipeline is often and regularly, a consistent routine maintenance program can significantly increase the efficiency and operational life of entire pipeline networks.
