Patent number: 8256303Abstract: A platform includes main transverse beams (“MTBs”), each supported by at least one hoist. It is determined whether a load on any MTB is different from the load on any other MTB by more than a predetermined amount. An MTB which has a load different from the load on any other MTB by more than a predetermined amount is selected and then vertically moved with respect to the other MTBs within a predetermined safety limit to transfer load between the selected MTB and the other MTBs while monitoring the loads on each MTB and the position of the selected MTB as vertical movement of the selected MTB proceeds. The monitored loads and position are compared with the safety limit; and the movement of the selected MTB stopped when either the desired load transfer is completed or the safety limit has been met.Type: GrantFiled: July 30, 2010Date of Patent: September 4, 2012Assignee: Rolls-Royce Naval Marine, Inc.Inventors: Iain J. Attwater, Iver D. Cayocca, Richard J. Shanks

Patent number: 7743721Abstract: A method for controlling a watercraft includes acquiring a desired heading of the watercraft, acquiring an actual heading of the watercraft at time T0, calculating a heading error by comparing the desired heading with the actual heading and determining a rate of change of the heading error. A P gain, I gain and D gain for use in maintaining the heading of the watercraft is determined and used to calculate factors related to heading error, cumulative heading error and rate of change of heading error. These factors are summed to form a control value for deflecting a nozzle of the watercraft to maintain a heading of the watercraft. Further embodiments include methods for calculating and correcting a heading of the watercraft, as well as methods for controlling roll out and sideways motion of the watercraft.Type: GrantFiled: December 1, 2004Date of Patent: June 29, 2010Assignee: Rolls-Royce Naval Marine, Inc.Inventors: Andrew F.

Patent number: 7144222Abstract: A propeller or propeller blade is manufactured using lattice block material to provide a structure which is generally hollow but for a three-dimensional lattice of support spars. The propeller or propeller blade, being predominately hollow, is substantially lighter than a solid cast propeller or propeller blade while retaining the desired strength due to the three-dimensional lattice of support spars.Type: GrantFiled: April 29, 2003Date of Patent: December 5, 2006Assignee: Rolls-Royce Naval Marine, Inc.Inventors: Francesco Lanni, John A.
