Offshore Chemical Cleaning and Descaling Solutions 2025
Offshore Chemical Cleaning and Descaling Solutions
Offshore oil and gas facilities rely on extensive piping systems to transport significant volumes of materials. However, maintaining these systems free from damaging substances such as rust, calcium scale, hydrocarbons, and other organic and inorganic materials is a continuous challenge. The accumulation of these fouling agents can drastically impact system performance, leading to reduced flow, increased pressure drop, impaired heat transfer, and in severe cases, blockages, corrosion, or leaks. While design efforts can mitigate fouling, complete prevention is unattainable, making chemical cleaning a critical necessity.
At Team Services and Rentals (TSR), we have developed advanced equipment, methods, and technologies that effectively clean a diverse range of systems, including produced water, closed cooling water, seawater cooling, flow lines, drains, pipes, vessels, coolers, heat exchangers, and wellhead X-trees.

Chemical Cleaning / Descaling Solutions
We offer a wide range of chemical cleaning and maintenance services to offshore energy operators, including drilling operators and vessel owners. Our expertise covers a variety of essential equipment commonly used in offshore and industrial operations. We have a proven track record of success in cleaning and maintaining the following systems:
- Plate exchangers
- Shell and Tube exchangers
- PCHE
- Evaporators and condensers
- Filters
- Process lines
- Gas supply lines
- Air supply lines
- Cooling towers
- Air coolers
- Fire protection water systems
- Cooling oil and lubrication circuits
- Diesel oil circuits
Many of our technologies can be applied to “live systems,” meaning production does not need to be halted for cleaning procedures. Using a controlled, chemical cleaning process, we precisely measure contamination types and clean the systems without compromising performance. TSR’s chemical cleaning services preserve pipe integrity and prevent the formation of future deposits, safeguarding against corrosion and enhancing system longevity.
Pre-operational Descaling
- Removal of stored scales (oxides, dust, and other debris) during the construction of various types of plants.
- Formation of a protective film over the de-scaled surface, resistant to corrosion.
- Reduction of commissioning time.
One-Phase Clean
Continuous research and development of new technologies have enabled TSR to apply the “One-Phase Clean” treatment in pre-commissioning descaling. This innovative cleaning concept provides significant advantages over traditional methods:
- Reduction in the time required for chemical cleaning.
- Lower water consumption, making it more efficient and environmentally friendly.
Online Acid Injection
Lime scale formation is a significant issue in many technical systems, particularly in oil production processes. Scale typically accumulates in equipment such as SSSVs in wells, master and wing valves, choke valves on Xmas trees, flow lines, produced water systems, separators, flair drums, hydro cyclones, coolers, heat exchangers, and cooling water systems. The presence of scale reduces flow, increases pressure drops, impairs heat transfer, and in the worst cases, causes blockages, corrosion, or leaks, which can lead to costly production losses and shutdowns.
While traditional methods such as chemical or mechanical cleaning (e.g., hydro jetting) can remove scale, they often necessitate halting production, which is costly. TSR specializes in “live” de-scaling, performing these operations on active systems without causing any production downtime. This minimizes operational disruption and ensures continued productivity during maintenance.
