Tiivistelmä
The purpose of this thesis was to create a cost comparison tool that can be used to compare the costs of the primary and secondary supports of the cooling water pipe
system of engine power plants. This thesis was done for Wärtsilä's Energy Engine
Power Plants department.
The cost comparison was created on Excel, where the costs of the three support options were specified from start to finish on separate sheets. Based on these sheets, the costs are linked to the comparison sheet, where the main costs of each of the three options are itemized.
The comparison tool was used in practice for a project being built in the Caribbean, which was implemented with Wärtsilä's standard secondary supports. The cooling system of the project was redesigned using prefabricated pipes, from which it was possible to create a cost comparison.
In the cost comparison, the standard option was the most affordable of these. The prefabricated options were slightly more expensive, but their quality is more consistent, and the installation time is shorter compared to the standard option. With the help of the cost comparison, it was possible to determine that the right option
had been chosen for this project.
The Excel tool was found to be functional, and in the future, it will be possible to use it already in the sales phase of the projects, when the final costs of the options
are known.
