Patent number: 7192322Abstract: A seagoing boat is driven by at least two rudder propellers and has a hull for transporting cargo or passengers. The rudder propellers are preferably embodied as electric rudder propellers. The hull has an approximately rectangular cross section amidships, to which flow-directing bodies are connected. A flow channel is configured between the skegs, the flow channel being embodied in a wedge-shaped manner with a continuous, preferably slightly bent enlargement in the direction of the bottom astern. The side walls of the flow channel are configured at least in part as even surfaces and taper off in the form of fin-shaped teeth having water displacement volume. The streaming effect of the flow channel generates a low boat resistance. The influence of the flow channel on the wake has a positive effect on the propulsion efficiency.Type: GrantFiled: February 17, 2003Date of Patent: March 20, 2007Assignee: Siemens AktiengesellschaftInventors: Adam Grzonka, Björn A.

Patent number: 7160161Abstract: A reduced pressure mixing device is for marine vessel exhaust gas with water, with the gas/water mixture that is produced in the device being passed out into the water in which the ship is floating. The device is designed such that gas and water flow through and to it longitudinally. Further, the device includes a centrally-arranged gas guide tube for the marine vessel exhaust gas as well as a propulsion water tube which is arranged coaxially around the gas guide tube and produces reduced pressure, with the tubes being located in an elongated housing.Type: GrantFiled: February 14, 2005Date of Patent: January 9, 2007Assignee: Siemens AktiengesellschaftInventors: Moustafa Abdel-Maksoud, Hannes Schulze Horn, Kay Tigges
