| Abstract (eng): | In spite of significant changes in cargo flow, the Northern Baltic Sea routes are still growing and continuing to play a key role to the Finnish economy because of its important trade connection. However, transporting versatile cargo demands efficient multipurpose vessels which should be cost effective for the industry and comply with all the future pollution control regulations of International Maritime Organization (lMO). Therefore, shipping industry needs to find solution and develop efficient vessel concept to survive in future competition. This thesis studies the feasibility of Multipurpose vessels as future dry cargo transportation on the Northern Baltic Sea and future trends in designing Multipurpose vessel along with its market condition, fleet development and trade condition. Five alternative machinery concepts for multipurpose vessels are also analysed to find the best environment friendly and cost-effective machinery solution for the future. This study analyses the current industry situation and identified future changes in cargo flow based on statistical data, market study, and other theses work. Future forecast is made for different cargo flow, supply and demand, multipurpose vessels fleet development and economy using SQL data mining forecasting techniques in Microsoft excel based on Time series of statistical data. Five alternative machinery concepts are analysed using operational profiles of a case vessel, with a program called "ShipMac" developed by Wärtsilä Finland Oy. The study found out that most of the cargo will come from the Finnish Metal and mining industry while reduction in material flows from forest industry in the future. The renewable energy industry provides greater opportunity in the near future. Significance of Multipurpose vessels will increase if the amount of project cargo volume increases as fierce competition from containerships is the reality today. Containerization of break bulk might change the fate of multipurpose vessel. However, the long term prospects of multipurpose vessel have been found to be promising. Furthermore, machinery concept studies found out that single screw propulsion with 2-Stroke dual fuel Wärtsilä engine running on LNG as the main fuel is the most economical solution and comply with all the future environmental legislations. Therefore, standardization of multipurpose vessel design suitable for Baltic Sea and developing LNG infrastructure is the recommendation for future research. |
