Water-lubricated polymer bushes are increasingly popular in sliding bearings of marine propellers, water turbines, and pump shafts. This environmentally friendly solution is relatively simple and usually proves to be durable. However, in practical experience one may also observe cases of rapid wear or even malfunctions of this type of bearing, some of which may be caused by insufficient flow of lubricant. The main purpose of the conducted research was to identify how different bearing types operate ...

The paper presents a novel device for capturing the energy of sea-waves and the construction of its model for conducting test in a towing-tank. The paper also presents the research program and general analyses on selecting the hull form and systems of anchoring and propulsion. In addition, it includes remarks and observations gathered following initial tests and measurements of the device operating in regular wave conditions.
