Rim–driven thruster, presented at SMM 2010 A rim-driven thruster mounted on a swing-out unit (design by silentdynamics GmbH) Voith rim thruster at SMM 2010 in Hamburg. The rim-driven thruster, also known as rim-driven propulsor/propeller (or RDP) is a novel type of electric propulsion unit for ships.
The first Azipod unit, installed on the Finnish fairway support vessel Seili in 1990, is now displayed at the Forum Marinum maritime museum in Turku, Finland.. In 1987, the Finnish National Board of Navigation made a co-operation proposal to the electrical equipment company Strömberg (later ABB) and the Finnish shipbuilder Wärtsilä Marine for the development of a new type of electric ...
Depending on the size of the motors driving these propellers, they could draw an insignificant amount of power or a large amount of power that requires much caution to operate. Another smaller subset of positioning thrusters is those used for maneuvering unmanned aquatic vehicles like Guanay II AUV tested by scientists from Spain (Masmitja, 2018).
An example of integrated electric propulsion in the Type 45 destroyer (GT: gas turbine; DG: diesel generator) Integrated electric propulsion (IEP), full electric propulsion (FEP) or integrated full electric propulsion (IFEP) is an arrangement of marine propulsion systems such that gas turbines or diesel generators or both generate three-phase [1] electricity which is then used to power ...
English inventor Francis Ronalds described what he called a propelling rudder in 1859 that combined the propulsion and steering mechanisms of a boat in a single apparatus. . The propeller was placed in a frame having an outer profile similar to a rudder and attached to a vertical shaft that allowed the device to rotate in plane while spin was transmitted to the propell
ABB provided an azimuth thruster for ShinNihonkai Ferries in form of the CRP Azipod, [2] claiming efficiency gains from the propeller (about 10% increase [3]) and a simpler hull design. Volvo Penta have launched the IPS (Inboard Performance System), [4] an integrated diesel, transmission and pulling contra-rotating propellers for motor yachts.
