-This invention relates t improvements in the transportation of volatile liquids invessels. particularly bulk oil carrying vessels. The invention comprises asystem for water f cooling the'deck'and sidesabove the water p which line, cool water being supplied over substantially an; the exposed surfacesadjacent the storage space forthe volatile liquid. In
t v this way theevaporation losses from theliquid cargo are mini ized.
The invention will'be fully understood from the following descriptiontaken in cone nection with the accompanying drawings in Fig. 1 is a-fragmentary perspective view of the forward deck of a tanker;
Fig. 2 is an enlarged side elevation, the i iew being taken along the line 11-11 of ig. 1; r
Fig. 3 is an'enlarged side. elevation, the view being taken along the line IIIIII of Fig. 1.
In the drawings, reference letter A. denotes the forward deck of a bulk oil carrying vessel having hatches 1, 2, 3, and 4 opening into the forward storage tanks, which contain volatile liquids. In accordance with myinvention, the deck overlying these tanks is divided into compartments by longitudinal and transverse bafile plates denoted respectively by numerals 5 and 6; 6'. These bafiEle plates serve as weirs or dams to retain water discharged from nozzles 7, 7, and 8, supplied from a pipe system 9 into which sea water is pumpe The battle plates have perforations or spill holes 10 at such a height as to form step-wise pools of water. In this way a fair uniformity of depth is maintained over the deck, notwithstanding its curvature. It will be understood that the sea water is discharged more or less centrally of the deck,as shown, and flows through the perforations 10 from each compartment to the next lower compartment. Holes 11 are formed in the bulwarks 12 and through these holes the water from the outer compartments flows down the vessels sides. A' shield plate 13 (Fig.3) is fitted outboard over the holes 11 to distribute the water in the form of a sheet.
A similar result could be obtained by allowing the water to overflow the tops of the bafiie plates, but in the event of the ships rolling or pitching too great a body of water may leave the pool. This is prevented by the plate area above the spill holes 10.. Asix inch depth of water is adequate'for proper --insulation.- The influx of watershould be suflicient to maintain a fairly rapid flow through the compartments and over the ships side. The pipe system 9 is provided with valves for the'control of: the flow of water,
and this may be varied as circumstances require.
The balile'plates'are secured to the deck angle-pieces spot-welded or riveted to the plates and deck, or in anyother suitable way. The deck surfaces included within the compartments,, and the lower portion of the baflie plates, are preferably covered with a suitable water-imperviouscoating. Y A dramage opening 14 is provided 11TH, corner of each compartment. Thisiopenin-g is-plugglgd when the compartments are to be filled. lugs-are fitted -in thescuppers,'so
that all the water discharged onthe deck will flow out. through the holesll.
The storage tanks amidship and aft. when filled with a volatile liquid, will be insulated with a water layer orfilm inthe same manner,
as shown and described lforlthe forward tanks. If it is not desiredto flood all the deck compartments, the transverse. bafiife plates 6= may be imperforate. Then, by closing the proper valvesin'the pipe system 9, the water flow may be restricted to a'limited portion of the deck, for example,the
.area included between battles (Sand 6', Fig. 1.
Heretofore it has been considered-impractical to transport very highly volatile liquids in bulk oil carrying vessels because of the conduction of heat to the material through the. unprotected deck and sides exposed to the atmosphere The present invention :makes it possible to maintains.- temperature in the storage tanksnot much above, the. temperature; of the water which the .vesselis traversing.
As an. additional safeguard against loss of volatile liquids and danger; from fire, I prefer to connect pipes to the storage tanks to convey all vapors that may be generated in them to a. point of discharge high up on the mast, or to a compressor and'cooler. Gondensate formed is returned to the tanks. The handling of vapors-from-the tanks in the general manner just. referred to is described and claimed in my application for United States patent Serial No. 143,278, filed of even date herewith. i 7' 7' V 5 '1 Y 1 Various changes and alternative arrangements may be madewithin the scope of the.
appended claims, in which it is my intention to claim all novelty inherent in the invention as broadly as the prior art permits.
