Abstract

In an hydraulic turning and stopping system comprising at least one blade 2 along each side of the hull of a vessel, each blade is mounted spaced from the hull by means of foreward and rear hydraulic piston 3, with the pistons advancing at different speeds creating a wedge shape between the vessel hull and blade. The system is designed so that as the front pistons extend, the increase in pressure in the hydraulic system caused by the increase in water pressure acting on the blade, will cause the rear pistons to extend at a greater rate to relieve the pressure and then return to reinstate either braking or turning facility.The number of blades on each side of the vessel should be equal and arranged symmetrically.

Description

H.A.T.S.S. Hydraulic Assisted Turning and Stopping Systems My invention is H.A.T.S.S. (hydraulic assisted turning and stopping systems). It is designed to enable large vessels ie. oil tankers, ocean liners, to stop in a shorter distance, and to turn in a smaller arc.
It works on a hydraulic system which when employed, forces blades out from the side of the vessel (as shown in the diagrams). This creates a 'wedge' shape between the vessel and blade, causing increased water resistance as the streamline dynamics ofthe vessel are impaired. If the blades are opened to different degrees, this will result in an inbalance which will turn the vessel.
This system is designed for use in emergency situations.

Claims (8)

CLAIMS H.A.T.S.S.
1. H.A.T.S.S. Is a system consisting of a hydraulic unit operating a number of pistons acting on blades mounted on to the sides of vessels.
2. The number and the size of the blades as claimed in Claim 1, will depend on the size of the vessel.
3. The number and size of the hydraulic pistons as claimed in Claim 1 will depend on the size of the vessel.
4. The orientation and position of the blades and pistons as claimed in Claim 1, Claim 2 and Claim 3, will depend on technical data gained from universities and or vessel shape.
5. When the system as claimed in Claim 1 is employed for stopping there will be a positive decrease in time and distance.
6. When the system as claimed in Claim 1 is employed for turning there will be a decrease in advance and transfer distances.
7. As the front pistons as claimed in Claim 1 and Claim 3 extend, the increase in pressure in the hydraulic system caused by the increase in water pressure acting on the blades as claimed in Claim 1 and Claim 2 will cause the rear pistons as claimed in Claim 1 and Claim 3 to extend at a greater rate until the pressure is relieved.
8. The system enables the rear pistons as claimed in Claim 7 to move in and out, to move out to relieve the pressure in the hydraulic system, and to reinstate either braking or turning facility.
