Abstract: A submersible towed body deployment and recovery device is disclosed. The device can include a support structure supportable by a surface watercraft, and configured for rotational and translational movement relative to the watercraft. Additionally, the device can include a towed body interface structure supported by the support structure and configured to interface with and support a wing and a forward end of a towed body. The support structure can be movable between a deploy/recovery position in which at least a portion of the towed body interface structure extends into water about the watercraft and a stowed position in which the towed body interface structure positions the towed body out of the water. Coordinated rotational and translational movement of the support structure can utilize buoyancy of the towed body in the water to minimize loading on the deployment and recovery device when moving between the deploy/recovery position and the stowed position.

Abstract: This invention is a floating docking port that allows ships to dock within the port structure and be loaded, unloaded, and refueled, while converting the energy generated from wave motion into a usable source of power. The docking port isolates the vessels from waves and adverse sea currents, which allows for more effective cargo transfer. The docking port is extremely large and functions as a storage and distribution center for naval vessels. The loading and unloading of cargo and containers is accomplished by a container handling system that utilizes hoists, railed carriages, and cargo elevators to facilitate efficient loading and unloading of containers.

Abstract: A conveyance system and method for delivering at least one component of a windmill to a location is provided. The system is provided with a transporter and a transfer system. The transporter is positionable adjacent a base at the location. The transfer system is provided with a plurality of rails, a support and at least one slider. The rails are positionable on the base and the transporter. The support has a first portion of the rails of the transporter thereon. The support is positionable along a second portion of the rails on a surface of the transporter, and slidably movable between a retracted and an extended position whereby the support is selectively positionable adjacent the base. The slider carries the component(s) of the windmill. The slider is slidably movable along the rails of the transporter and the base whereby the component(s) is/are slidably transferrable between the transporter and the base.

Abstract: A method for determining heave and heave rate for a vessel is described. The vessel includes an inertial navigation system (INS), and sensors for the INS being located at a point A of the vessel, the vessel having a zero heave reference point B, and the described method provides heave and heave rate at a point C of the vessel. The method includes determining reference coordinates for points A, B, and C of the vessel, generating a velocity signal representative of a velocity at a point on the vessel, generating a heave rate signal based upon the velocity signal, and generating a heave based upon the heave rate signal.

Abstract: A transporter for removing an offshore platform has an oblong structure with a U-shaped cross section, rotatable by ballasting. The transporter is adapted to remove and carry both a jacket and a topsides simultaneously.

Abstract: A sea faring transshipper for transferring cargo from a bulk carrier to a secondary vessel comprises a pair of units provided with mutually engaging connectors for connecting the units together along a direction of travel of the transshipper. Each unit comprises a pair of spaced buoyant vessels, a platform supported by the buoyant vessels in a raised position above the buoyant vessels through wall members extending upwardly from the buoyant vessels and a hull contacting member extending between the buoyant vessels for contacting the underside of a bulk carrier being unloaded. The platform, wall members and hull contacting member define an opening for surrounding the bulk carrier being unloaded. The transshipper also includes a ballasting system for maintaining the hull contacting member in contact with the hull of the bulk carrier being unloaded. A method of unloading cargo from a bulk carrier using the transshipper is also provided.

Abstract: A transporter for use in a method for removing a jacket for an offshore platform includes an oblong structure rotatable by ballasting, with a sliding saddle which is movable in the longitudinal direction of the oblong structure and adapted for securing the jacket, thus enabling the jacket to be moved in relation to the transporter by the sliding saddle after being attached to the sliding saddle and released from the seabed.
