What we remove
We specialise in the chemical removal of every deposit type that hampers efficient operation in the offshore and maritime sector.
Corrosion
(Rust and oxide deposits)
Iron oxide and rust build up over time and significantly reduce pipe capacity. We remove deposits down to clean metal using selective chemicals that do not attack the pipe wall.
Scale
(Calcium carbonate and minerals)
Scale and mineral deposits from seawater and process fluids gradually block the pipe. Chemical dissolution restores full pipe bore.
Biofilm
(Biological deposits)
Microbial growth causes MIC corrosion. We remove biofilm and permanently disinfect the surface.
Humus
(Organic sediments)
Organic material and humus accumulate in low-lying pipe sections and create blockages. Chemical treatment dissolves and removes sediments completely without any mechanical intervention — critical for pipes with limited access on offshore and maritime installations.
“We know the offshore and maritime sector from the inside.”
ABOUT US
Certified personnel
with experience from the offshore and maritime sector
Clean Marin AS is staffed by certified personnel with solid experience from rigs and ships in the North Sea and internationally.
Our team holds relevant offshore certifications and has first-hand understanding of the operational and safety requirements in the offshore and maritime sector.
We use approved chemicals and documented methods to ensure pipelines are restored to original condition — without damaging the pipe material.
Approach
How
we work
Five documented steps that ensure the pipeline is ready for production — every time.
Steps
Documented process
Survey
Thorough inspection and condition assessment of the pipeline network. Documentation of deposit type, location and extent.
Chemical analysis
Identification of deposit type and selection of optimal chemical blend. Safety assessment for pipe material and environment.
Cleaning process
Controlled circulation of chemicals dissolves the deposits. Continuous monitoring of pressure, temperature and pH.
Rinsing
Thorough rinsing with clean water removes chemical residues and dissolved deposits. pH neutralisation.
Verification
Documentation of results with before/after measurements. Written report confirms that the pipe is back to original condition.
Questions & answers
Frequently asked questions
What is pipe rehabilitation?
Pipe rehabilitation is the chemical removal of deposits such as corrosion, scale, biofilm and humus from the inside of pipelines. Clean Marin AS restores pipes to original condition with up to 98.3% purity level without damaging the pipe material.
How long does chemical cleaning of a pipe take?
Average treatment time is 24 hours per pipeline. Exact time depends on deposit type, pipe dimension and length.
Do the chemicals damage the pipe material?
No. We use selective, approved chemicals that dissolve deposits without attacking the pipe wall. All chemicals are eco-safe and documented.
Which deposits can you remove?
Corrosion (rust and oxide deposits), scale (calcium carbonate and minerals), biofilm (microbial deposits that cause MIC corrosion), and humus (organic sediments).
What is MIC corrosion?
MIC stands for Microbiologically Influenced Corrosion — corrosion caused by microbial activity in biofilm. We remove biofilm and permanently disinfect the surface to prevent further corrosion attacks.
Where does Clean Marin AS operate?
Clean Marin AS operates in Norway, the North Sea and internationally — primarily on rigs and ships in the offshore and maritime sector.
