It is imperative that the structural integrity of the scrubber and associated pipework is constantly checked for signs of leakage or corrosion. In view of the acidic nature of the scrubber washwater, correct material selection for the scrubber body, pipework, components and accessories, together with good installation, but also very important, maintenance and repair workmanship are critical to avoid subsequent safety issues.

An exhaust gas cleaning system, also known as scrubber or gas scrubber, is a device installed on board of marine vessels that, quite literally, “scrubs” harmful sulfur oxides from exhaust gases. The technology is commonly installed on ships seeking compliance options in the face of tighter emissions regulations conform the new International Marine Organisation emission regulations. The new emission regulations, known as IMO 2020, mandates a maximum sulphur content of 0.5% in marine fuels globally.
Marine Scrubbers have been among the top choices for owners to comply with IMO 2020 Sulphur Cap, as an alternative to low-sulphur fuels, primarily due to the cost savings they offered to owners of large ships as compared to expensive new fuels.
ISTECH Metal Finish BV carries out welding repairs according to Welding Procedure Standard NEN-EN-ISO 15614-1, level 2. We carry out inspections during welding and upon completion, performed by qualified engineers.
Our goal is to get the job done with minimum of Downtime and our Service and Repair Team is 24/7 standby and always ready to go anywhere in the world. We keep in direct contact with Fleet Managers, Technical Managers, Chief Engineers, Ship Owners, Ship Agents, Port Authorities and can take care of Hot Work permits. We can also arrange Launch services to Anchorspots.
Marine Scrubber is a system that is designed to by the use of water wash the exhaust gases from main, auxiliary and boilers to remove sulfur dioxide (SO2) which is a toxic gas, that is directly harmful to human health. There different designs in the market today however they could be divided into two categories, open and closed types. Power consumption of operating a scrubber system is typically between 1-2% of main engine power.
The residue is free (unAlloyed) iron on the surface. Free iron should not be confused with Alloyed iron which is a major component of stainless steel, or with ferrite which is a specific type of crystalline structure and a normal component of stainless steel, especially cast stainless steel. If non-sufficient surface treatment of the stainless steel on completion of fabrication and / or installation on board will definitely resulted in an active surface condition instead of the required passive surface condition. This will give free iron the opportunity to embed itself so that the passive oxide film shall been penetrated through this ferrous contamination. Iron residue may also be transferred to Stainless steel surfaces from materials which were previously used on steel or iron parts. Of course, iron or steel shot or grit used to remove scale or other materials from the Stainless steel items would leave iron residue on the surface. One of the most difficult sources of iron residue to avoid is the atmosphere itself. Industrial areas have a surprising amount of iron in the air. This iron “falls out” onto exposed items, including previously cleaned Stainless steel parts. Also, water which is used to “clean” the surfaces may itself contain iron which will be deposited onto the surfaces thought to be clean. Note that water may also contain other chemicals which may leave rust-colored deposits which may be mistaken for indications of the presence of free iron. Appearance – Free, unAlloyed iron on the surface of any item will oxidize (rust) given the appropriate conditions (warmth, moisture, and oxygen). The reddish brown deposits are easily recognized Contamination on Stainless steel surfaces with free iron is common. It can be avoided only with very careful and correct surface treatment including professional pickling and passivation and related technical cleaning processes.
