International Classification:

B63B 59/00
E02D 5/60

US Classification:

114222, 405216

Abstract:

Systems and processes for controlling and/or preventing fouling of marine vessel hulls and fixed structures are disclosed. The systems and processes deliver an anti-fouling composition through a dispersing means, such as dispersion tubing, to the surface of a vessel hull or fixed structure below the water line. Also disclosed are methods of controlling the delivery of an anti-fouling composition to the surface of a vessel hull or fixed structure below the waterline, including the steps of generating signals representative of parameters such as current flow direction and speed and water temperature, to identify and control the proper volume release rate of the anti-fouling solution.

Abstract:

Systems and processes for closing openings in marine vessel hulls are provided. The systems and processes facilitate repairs and maintenance of marine vessels by closing openings in the marine vessel hulls to permit dry access to compartments in communication with the openings. The processes and systems incorporate a cover constructed from a lightweight material such as fiberglass, a viscoelastic material such as polyethylene or polyurethane, and blends thereof. The cover is guided in place to effectuate closure of the opening by a track device that receives at least two of the peripheral edges of the cover and directs the cover to the proper position to close the hull opening. The cover may be lowered into place by use of a hoisting device such as a davit.
