UHP retro-jetting of heat exchangers on a Norwegian FPSO to prepare for chemical flushing – high-performance jetting unit and 24/7 pump engineer cover delivered precision cleaning within a tight window, avoiding downtime and keeping the operator’s maintenance schedule on track.
Sector: Offshore oil & gas – production / maintenance
Location: Norwegian sector FPSO (anonymised)
Client: Global energy operator and specialist alloy vendor (anonymised)
Services: UHP jetting, heat exchanger retro-jetting, specialist pump engineering, logistics and import/export coordination
Overview
As part of a planned maintenance campaign, the operator needed two heat exchangers prepared for a critical chemical flushing operation. Because of the materials involved and the risk profile, the exchangers had to be retro-jetted to a high standard before any chemicals were introduced.
The work demanded niche industrial cleaning expertise, high-pressure equipment and continuous technical support to guarantee safety, precision and schedule.
The Challenge
The client’s requirements were clear:
- Deliver retro-jetting of heat exchangers to a standard that would allow chemical flushing to commence without delay.
- Operate around the clock, keeping the UHP jetting unit running reliably on a remote Norwegian FPSO.
- Manage complex import/export and mobilisation logistics to bring specialist kit and people into Norway quickly.
- Maintain tight control over safety and quality throughout.
In short: a high-spec job, in a tight window, a long way from home base.
Sureclean’s Solution
Sureclean was selected for its track record in specialist UHP jetting and heat exchanger cleaning and its ability to mobilise both equipment and manpower rapidly.
The solution included:
- Deployment of a UHP Jetting Unit to Norway, configured for heat exchanger retro-jetting.
- Two experienced Pump Engineers assigned to provide 24/7 cover – one on each shift – ensuring continuous operation, troubleshooting and optimisation of the jetting process.
- Pre-arranged import/export documentation and logistics, smoothing the movement of equipment to and from Norway and allowing work to start immediately on arrival.
On site, Sureclean’s team:
- Set up and operated the UHP jetting unit to retro-jet the two heat exchangers, removing deposits and contaminants.
- Worked in shifts to provide uninterrupted pump and jetting performance, protecting the client’s tight maintenance schedule.
Results
The campaign delivered:
- Both heat exchangers thoroughly retro-jetted, meeting the cleanliness standard required for chemical flushing.
- Zero unplanned downtime for the jetting spread, thanks to 24/7 engineering cover.
- Swift mobilisation and demobilisation, with import/export formalities handled up-front, minimising administrative delay.
- The subsequent chemical flushing operation started on time, avoiding knock-on delays to wider maintenance activities.
- A reduction in downtime risk for the heat exchangers, helping the operator maintain operational continuity.
