Patent number: 11319029Abstract: The present invention provides an improved device for attaching a watercraft to another structure such as another watercraft or a fixed structure, such as a dock. The apparatus comprises a spacing bar and specialized, quick connecting and releasing attachment devices that allow the watercraft to be quickly and effectively moored to other structures on the water without the risk of collision or damage to the watercraft. The quick-connect devices may be positioned near ends of the spacing bars to effectively hold the watercraft at a predetermined distance from the other structure. The device may further include tensioning mechanisms that are operable to keep the spacing bars at a substantially orthogonal orientation relative to the watercraft to maintain the pre-determined spacing between the watercraft and the other structure.Type: GrantFiled: July 30, 2021Date of Patent: May 3, 2022Inventor: Scott Logan

Patent number: 7493868Abstract: A system is provided for rigidly attaching a supply ship to a receiving ship to facilitate efficient transport of materials there-between even when the vessels are subject to heavy seas and weather. A telescoping truss assembly is provided on the first ship, and has a distal end configured to mate with a receptacle assembly on the second ship. Cables are disposed within the truss and are used to draw the truss and receptacle assemblies into engagement with each other. Once the assemblies are engaged, a hydraulic system is used to draw the two ships together, rigidifying the truss assembly and fixing the two ships in a “catamaran” arrangement. Subsequent transfers of materials between the ships can be carried out without the need to compensate for the relative dynamic vertical and horizontal displacements between the ships due to wind and waves.Type: GrantFiled: July 13, 2006Date of Patent: February 24, 2009Assignee: Lockheed Martin CorporationInventors: David B.

Patent number: 6854408Abstract: An apparatus as described for mooring to floating vessels (10, 12) side-by-side. The first vessel (10) is moored to the seabed by a single point mooring system (14). The apparatus comprises an arm (20) with proximal and distal ends. The arm (20) is mountable on the first vessel (10) for rotation about a vertical axis and the distal end projects outwardly from the first vessel (10) in use. A substantially inelastic mooring line (24) is attached to the distal end of the arm (20) and is securable to the second vessel (12). The resilient means (26, 28) is operable to allow limited rotation of the arm (20) about the axis in the first direction in response to tension in the mooring line (24) which exceeds a pre-determined value. The resilient means automatically restores the arm (20) to its former position upon reduction of the tension below the predetermined value. The arm (20) is freely rotatable about the axis in a second direction opposite to the first direction.Type: GrantFiled: October 22, 2003Date of Patent: February 15, 2005Assignee: Bluewater Energy Services BVInventor: Jacob De Baan
