At Topline Limited, we employ exceptional engineers and utilize the best equipment in pipeline services.  We deploy integrated services to enhance onshore and offshore pipeline performance.

We tailor exacting solutions to meet client requirements in the following areas:

  • Pipeline Commissioning
  • Pipeline Pre-Commissioning
  • Pipeline De-Commissioning.
  • Pipeline Flooding/ Auxiliary Pumping
  • Hydro Testing
  • De-watering


Topline’s pipeline pre-commissioning services give your pipeline the best possible start in service and help reduce future corrosion, improve efficiency, maximize throughput and prevent hydrates from forming.

We can validate the line integrity by hydro testing to a variety of pipeline codes, allowing you to meet regulatory requirements.

Thorough cleaning may mitigate against long term corrosion and we offer a range of solutions to clean the pipeline, depending on the specification.

For natural gas and petrochemical pipelines, thorough drying or conditioning is essential to prevent the formation of hydrates and deliver the product purity you need. We reduce drying time and move the line into production as quickly as possible using air, vacuum, nitrogen, or chemical swabbing. A final purge with nitrogen minimizes explosion risk. 

In addition, our pipeline commissioning services focus on helping you to get quality product into your pipeline safely, quickly, and efficiently – enabling faster start up.

Topline has the experience and proven systems to help you cost-effectively decommission assets in ways which are both safe and environmentally responsible.

Pipelines can be flushed and cleaned via chemical and/or mechanical methods for in-situ abandonment or where required, mothballed for future use as we parade some of the best engineers and equipment in pipeline services.
