Title: Improvements in or relating to protection of ships' hulls against corrosion and fouling
Inventor: WAITE WILLIAM GODFREY
IPC: B63B59/04
Filed: 1957-05-22
Abstract: 858,904. Preventing corrosion. HUGHES & CO. Ltd., F. A. May 14, 1958 [May 22, 1957], No. 16234/57. Class 123(1) Corrosion of ships hulls is prevented by distributing a substantially water-insoluble liquid marine growth deterrent over the underwater surface combined with simultaneous impressed current or sacrificial anode cathodic protection. The deterrent may be dispersed in a stream of gas, for instance air or the exhaust gases of an internal combustion engine, the dispersion being discharged from spaced outlets in longitudinal tubular housings 10, Fig. 2, located above or below the bilge-keels 11 of a ship 12. As the deterrent rises to the sea's surface it is evenly distributed on to the underwater surface of the ship and forms a film thereon, this being facilitated by the addition of a wetting-agent. The deterrent has a greater electrical resistance than the ambient water so that the current required for adequate protection of the hull can be reduced. The housings 10 are connected through the hull to a pipe 13 to which is connected a pipe 20 supplying a mixture of gases and deterrent. The gases are compressed by a compressor 21 driven by a motor 22 and the deterrent is pumped by an injector-pump 27 from a tank 29. Each housing 10, Figs. 4 and 5, comprises a number of sections 10A, 10B each having a channel 49 therethrough for the gases and deterrent, a channel 54 containing a platinum wire electrode 55 and a channel 50 containing a bus-bar 51 which supplies current to the electrodes. The channel 49 has outlets 53 to allow escape of the gases and deterrent and channel 54 has slots 56 to allow access of sea-water to the anode. In a modification (Fig. 3, not shown), the housings 10 are located underneath the hull near the keel-plate whilst cathodic protection is effected by scarificial anodes mounted above the bilge keels. Suitable deterrents are liquid hydrocarbons such as kerosene and light diesel oils with or without an additive toxic such as oxides of copper, arsenic or mercury; and organic compounds 2:4-diisobutyl phenol, phenyl mercury nitrate and acetate, pyrethrum, pentachlorophenol, derris extract, ethyl bromoacetate, zinc phenyl dithiocarbamate, diphenyl arsenious acid, dichlorodiphenyl-trichloroethane and p-dichlorobenzene; also trialkyl or triaryl tin compounds may be used as additive deterrents. The deterrents &c. are described in greater detail in Specifications. 851,902, 852,268, 852,882 and 858,905.
