Abstract
A floating boom.
ABSTRACT
A floating boom comprising a number of separate buoyancy chambers (1), a skirt (2), a ballast (3) and an air supply conduit (4), is safeguarded against bursting of the buoyancy chambers (1) by means of at least one duct (8) extending from the interior of the buoyancy chamber (1) to an outlet that is located bet-ween the buoyancy chamber (1) and the lower edge (6) of the skirt. By letting the air supply conduit connection with each single chamber open into said duct (8) a non-return valve function is further obtained in a simple manner.
There is also described a method of obtaining supplementary security against all buoyancy chambers (1) being emptied if a single buoyancy chamber (1) is punctured during the use of the floating boom .
(Fig. 1).

The invent~o~ also relate~ to a method of usin~ a floating boom of said type, in which the air supply conduit is disposed at the other edge of the skirt.
Floating booms of the above mentioned type are known, in wh~ch the buoyancy chambers are designed a~
closed chambers with an air supply, and possibly with a valve for d~scharging air from the buoyancy chamber in connection with reco~ery of the floating boom. The lay-1ng out o~ such floatin~ boom necessitates, in order to avoid the buoyancy chambers bursting, that the inlet pres~ure to the air supply conduit i~ kept lower than the bursting pressure of said chambers. If one of the buoyancy chambers i8 punctured, all buoyancy chambers empty through the common air supply conduit, following which the floating boom sinks.

The invention will no~ be explalned in detall by mean~ of ~ome embodiments with reference to the 6 drawin~s, in which ~ ig. 1 i3 a side elevation o~ a floating boom acGordlng to the invention, ~hown in the position o~

The embodiment of the floating boom illustrated in Fig. 1 includes buoyancy chambers 1 ~or~ed alon~
one edge 5 of the floatin~ boom and ducts 8 extend-ing downwards from the buoyancy chambers in the posi-tion of use. A skirt 2 is positioned below buoyancy chambers l. Said skirt is provided with reinforce~ents 10 ~long the lower edge for securing a ballast chain 3 by means of fixing members 11. Said b~llast chain 3 serves in a known manner to maintain the float~ng boom in a substantially vertical position in the sea. An air supply conduit 4 with a branch tube ~ i8 secured to ballast chain 3. The branch tube ~ is inserted into duct 8 of buoyancy chamber 1.
The ~unction of the embodiment according to the invention illu6trated in Fig. 1 will be explained in the following with reference to Fig. 2, from which cer-taln parts have been omitted in respec~ of clearness.
Buoyancy cha~ber 1 i8 inflated by pressurized air 3~ being supplied through air supply conduit 4 and branch tube 7. The level of the water in the duct will .~ :

from the outset be the same a~ the level c of the surrounding sea water. In ~tep with rlsing pressure in the buoyancy chambar, the water level drops and finally reache~ level a at the outlet of the duct, Pollowing which a further pressure riee causes air to e6cape through the duct. After lnflatlon, the w~ter level in the duct will be equa~ to level a. I~ a chamber i8 punctured the pre~surQ above the w~ter ln the duct drops, thereby causing the water level to ri~e in the duct. When the water has attalned level b, the water flows down ~nto the alr 13upply conduit and 80 bars the connection between the buoyancy chambers, following which the water in the duct of the punctured buoyancy chamber may rise to water level c; causing the pressure at the outlet to become equal to that o~
the sea surrounding the floating boom on thls level.
Briefly spoken, upon the puncturing of one chamber the pressure in the other chambers drop~ from the water pressure at a to the water pressure at b. Said pressure drop i8 eliminated by making use of the m~thod according to the invention, because the water-~illed air supply conduit obstructs air transfer from the intact chambers to the punctured chamber. It will be recognized from the above description that it is important that branch tube ~ i5 inserted from below.
when the method according to the invention i8 used.
The barring ls solely determined by level b of the outlet of the air supply conduit.
In the embodiment illustrated in F~g. 3 the barring between chambers 1 i8 ensured from ~tart by means of a non-return valve 9 mounted on air supply connection ~ of each chamber 1. In Fig. 3 the air supply conduit is dispo3ed at the lower ed~e 6 o~

pressure. In this respect the ducts ensure that the posltive pressure in buoyancy chamber 1 does not exceed the pressure di~erence between buoyancy chamber 1 and the outlet of duct 8.
In the method according to the inventlon the filling of the air ~upply conduit with water may elther be effected by pumping water into the air supply con-duit or by thrustlng one end o~ th0 air ~upply conduit down into the water and let the water flow in by itself, while the air in the air supply conduit escapes through the ~utlets of the buoyancy chamber~ and bubbles o~!t from the duct outlet~.
There are many possiblliti~s of varylng a ~loating boom according to the invention, B . g . the alr supply condult may pass along the upper edge, provided the outlet to the indlvidual buoyancy chamber be located in the duct associated with the chamber. The outlet of the ducts associated with the chamber may al80 be positioned on an arbitrary level o~ the ~loating boom, which merely has to be positioned below the buoyancy chamber, e.g. one of the rubber sheets 13 or 14 may end above lower edge 6 of the floating boom or there may be an opening in one of the rubber sheet~ 13 or 14 on an appropriate level.
A substantial advantage of the floating boom accordin~ to the invention over and above other ima~i-nable solutions to the problems with respect to exce~s pressure security of and barring between the buoyancy chambers consists in that said problems are solved without introducing other components such as ~alves or the like, which would increase the risk of failure and requirement for service, overhaul, spare parts and edu-cation of staf f .
