... Shafting system in a ship is probably its most critical component. Problems in the propulsion shafting, connecting engine with propeller may let the vessel dead in the water. This study focuses on three components of the shafting system which are well known to cause problems. These are the aft...

... Marine structures, such as ships, are vulnerable to fouling, leading to increased hull resistance (decreased propulsion efficiency). In order to reduce this phenomenon, ship owners tend to clean the hull and the propeller surface prior to dry docking. It is essential to understand which part...

... for two different ships and some key points are discussed. The potential of such methods is displayed and the possibility of distinguishing the hull from propeller effects is approached. energy conservation efficiency evaluation monitoring timely evaluation weather significance resistance...
