Offshore project technical services firm Crondall Energy (Hampshire, England) will be collaborating with educators and innovators on a study to better industry understanding of the potential flow assurance benefits of internal coatings.

The study, to be completed in collaboration with Heriot-Watt University, The Oil & Gas Technology Centre and The Oil & Gas Innovation Centre, will be spearheaded by Crondall Energy’s in-house Flow Assurance team in Aberdeen.

Internal Coatings Study

The research methodology will consist of a three-tiered approach:

  • Data mining will be implemented to use previously published data, paired with expert knowledge, to develop computational models of the behavior of polymeric coatings, which will then be examined;
  • The experimental phase will look at correlating wax deposition behavior with coating surface parameters and flow characteristics; and, finally,
  • The study will establish potential alternative polymer materials for improved internal coatings.

Offshore project technical services firm Crondall Energy will be collaborating with educators and innovators on a study to better industry understanding of the potential flow assurance benefits of internal coatings.

“Commercially acceptable pipeline internal coatings are available and employed in the prevention of deposit build up, as well as corrosion prevention,” said Crondall Energy Subsea Director and Flow Assurance expert Murray Anderson.

“However, the [behavior] of these coatings in the harsh conditions experienced in oil and gas pipelines is poorly understood. Consequently, the polymers currently used in such organic-based coatings are compromised due to the lack of fundamental knowledge of their performance at operating conditions. Our study aims to evaluate current internal pipeline coatings, identify potential novel solutions and systematically test them in laboratory equipment at simulated pipeline conditions.

“Internal pipeline coatings offer significant opportunities for the development of small pools in potentially eliminating the need for the major elements of conventional flow assurance solutions, including chemical, heat and insulation requirements. However, there is currently no significant experimental evidence that allows a robust estimate of how a coated system might perform under oil and gas pipeline operating conditions.”

The results of the study will be available to the market, according to Crondall.
