This thesis explores the financial and operational impacts of integrating Dynamic Maintenance
Planning (DMP) and swing set components into a Lifecycle Agreement for Wärtsilä’s 12V50DF
engines, specifically in marine applications.
The primary goal of this research is to develop a calculation model that compares the total cost and
downtime of a Lifecycle Agreement that includes DMP and swing sets versus one that does not use
these solutions. Using real-world data from Wärtsilä’s Service Configurator and applying it to a
marine setting, specifically a Dual Fuel Diesel Electric Liquefied Natural Gas carrier, the study calculates the differences in maintenance costs, downtime, and overall engine performance across a 20-year lifecycle with 5 000 running hours per year, to a total of 100 000 running hours.
The thesis also explores the challenges in justifying the high initial investments required for swing set components, as well as the potential for cost savings and improved engine uptime that these solutions offer. Additionally, the research delves into the principles of preventive maintenance,
DMP, and the role of swing sets and exchange parts in the maintenance of Wärtsilä’s engines,
providing insights into how these factors can influence operational efficiency in the marine industry.
