Propulsion system for the ships is for transferring the developed power by the Main Engine forming a
power train and deliver the power to the propeller for obtaining the required thrust. The design phase of shafting
includes Material Selection, selection of couplings, bearings, and type of stern tube used.
The current projects use the shafting with the material CS45E. The material is of Carbon steel with grade. The
design of shafting is a state of art and alignment calculations plays a vital role. In this regard shafting analysis with
static and dynamic considerations including bearing reactions using software ANSYS will be conducted.
The ship is designed with two intermediate shafts and one tail shaft and marine lubricated stern tube and
bearings. The design of shafting is done from on strength basis, and checked with Lloyd’s register of shipping rules,
which are standard rules to maintain quality of the products. The shaft modeling is done in CATIA. The change of
material by replacing it by composite is done in HYPERMESH and results will be compared. The shafting analysis
conducting the calculations arriving at the shafting system alignments are shown as results.
