Sažetak
The main propulsion shafting belongs to a narrow group of the most vital systems on the ship. It influences reliability of the propulsion plant as well as the overall design of the vessel. As high-strength steels possess a favorable property to allow reduced shafting diameters, which results in enlarged torsional flexibility of the shaftline, in this paper, the flexible shafting system approach is presented. In general, this concept offers better torsional vibration behavior of the propulsion system, reduces overall investment costs, enables smoother shaftline alignment and finally, permits shaftline, as well as the engine room, length reduction. Unfortunately, this approach introduces some unfavorable side effects. Therefore, some practical design and manufacturing notes are also given. Finally, two real-life main propulsion shafting design examples are presented. The sea trial vibration measurements proved the concept as well as the performed analyses.
