Tiivistelmä
The purpose of this study was to gather information about wet electrostatic precipitator of seagoing vessel for the use of Valmet Marine Services. WESP is a pollutant reducing product that is installed at the end of a flue gas line. At the time there were no Valmet WESP systems in marine use. The focus was on spare parts and maintenance need of WESP equipment. The main tool for information gathering was expert interviews. Information was used to assess the criticality of WESP parts by the means of criticality analysis tool. With the help of analyzed data and formerly known practices from supplied scrubber projects a two-year spare part list was formed.
The key findings were that WESP does not require much maintenance. The most critical parts were found from the emitter system. Interviews supplied relevant knowledge regarding the life-cycle management of the system. Criticality analysis including auxiliary equipment and two-year spare part list are recommended to be used when WESP system is sold and detailed equipment of the project is known.
Further research is recommended for safety perspective and its effects on criticality. The effects of marine environment on faultiness and durability of equipment are unknown which inflicts high uncertainty to true upkeep need.
