The convenient layout of the equipment and the closed environment of the PDD reduce the execution time and improve the working conditions. The isolated environment created by the superstructure, deck and roof of the PDD significantly reduces the environmental impact. The isolated environment inside the PDD is controlled in temperature and humidity. The air filtering and waste water collection systems remove dust and other substances coming from the operation, stopping pollutants from getting into the IW. | 04-23-2009 |
| 20110146554 | ELEVATED DOCK - An elevated dock designed to lift boats out of the water when not in use is provided because storing a boat in the water exposes the boat to contaminants in both fresh and salt water. These contaminants attach to the bottom of the boat severely impeding the performance of the boat. Cleaning these contaminants off of the boat is time consuming and costly. Repeated cleaning of the boat will eventually result in damage to the hull. The elevated dock uses polymer to form adjustable pontoons that can easily be fitted to a variety of sizes and styles of boats. An embodiment of the elevated dock uses an articulated set of pontoons for lifting sailboats. The elevated dock can be deployed completely independent of the dock, eliminating unwanted stress to the dock. The unique gusset design, free-floating feature, articulated pontoon option coupled with the unique manner in which the pontoon length, width and volume can be adjusted for various boat types and sizes. | 06-23-2011 |
| 20110277675 | FLOATABLE DRY DOCKS - A floating dock including a submersible platform including at least one buoyancy tank wherein the buoyancy tank has a plurality of compartments each of which has a permanently open vent through which water is freely flowable into and out of the compartment and an inlet which enables air to be expelled from the compartment into the atmosphere or enables compressed air to be supplied to the compartment via a non return valve which causes water within the tank to be forced out via the vent, thereby increasing the buoyancy of the tank. The vent does not have any valves associated with it and is permanently open to the sea. As a result the floating dry dock of the present invention may be lowered and raised faster than conventional dry docks which rely on valved vents to control entry and exit of water into and out of their buoyancy tanks. | 11-17-2011 |

The control system can control the trajectory of a flexible gas-filled lift bag and attached load by opening or closing inflation and deflation valves based on ambient pressure readings obtained during a lift. Stable control can be achieved and maintained without having to directly measure the actual volume of gas in the lift bag, and without having to accumulate measurements of gas flows into and out of the bag. A controller can pre-determine limits of instability and lift control parameters, then use this information in conjunction with ambient pressure readings to prevent the system from becoming unstable during a lift. User intervention is generally unnecessary to maintain the system's instability. | 12-12-2013 |
