Depolluting ships

(Anti-pollution vessel)

What Are Anti-Pollution Vessels

Anti-pollution vessel is a special type of ship which is employed to absorb pollutants from oceanic water during ship accidents or any other incident which has lead to pollution at the sea The pollutants can include oil spill because of an accident garbage left behind by vessels or other kind of floating marine debris resulting from ocean dumping

Anti-sea pollution ships are designed to carry-out complete 360 pollution combating operations at the sea In todayrsquos times on account of extensive oceanic contamination and pollution even at the coastlines the need importance and presence of such vessels has increased manifold

These anti-pollution ships are equipped with gadgetries and systems which help in recovering back

the polluting substances from the sea water Some of the main equipment includes pumpers liquid

disinfectant substances oil spill kits oil booms and oil dispersants which can be sprayed to clean

up the contaminated areas Alongside to facilitate the process of cleaning contaminated shore areas

and remove debris from the sea there are specific container systems provided which act like bins

There are various marine companies that specifically focus on providing such anti-pollution vessels

to the required oceanic areas While most of such companies have come up with their anti-pollution

shipsrsquo innovation to be used in any oceanic domain or shore there are also certain companies that

have designed their vessels to cater to only a specific location in a particular nation Anti-pollution

ships thus help ships involved in an accident to fight oils spill at the sea

Sepor SPA is a company has two such anti-oil pollution ships ndash the Optimist and the Acqua

Azzurra Both these vessels have been engaged in many de-contaminating operations of the oceans

and bear the hallmark of the four decades of the companyrsquos expertise in designing such unique

technological systems Both vessels offer speeds of about 10 knots and while the Optimist is slightly

smaller as compared to the Azzurra its services are par excellent nonetheless These vessels help

in cleaning oil spill or other form of marine pollution a variety of ways

In contrast the Japanese came with the prospect of building an anti-pollution vessel for two of its

major water bodies that are sources of vital marine products and commodities for the people

Accordingly the vessel KAIKI was built which not only ensures appropriate cleaning operations

from time-to-time but also doubles as an observation vessel Constructed at the Mitsubishi

shipbuilding yard the vessel is built using alloys of aluminium and is equipped with several state-

of-the-art gadgets to help fulfill its observation studies better

Anti-sea pollution ships and anti-oil pollution ships are the 11th hour measures developed in order

to combat the now-visible threats of marine pollution and minimize the effects of marine pollution

Though these vessels cater extensively to the maritime community there cannot be any denying

that the callousness of the marine operators has been instrumental in their creation in the first

place

VESSEL FOR REMOVING LIQUID CONTAMINANTS FROM THE SURFACE

OF A WATER BODYA vessel for use in floating contaminant liquid such as oil from the surface of water has a hull forming an immersed inverted channel into which surface layers flow as the vessel advances the hull being shaped so as to guide into accumulation zones from which the liquid is drawn by a pump into settling tanks disposed in pontoons from the tanks and the contaminant liquid being collected in the tanks and react 11 Claims 8 Drawing Figures

BACKGROUND OF THE INVENTION

The present invention relates to systems for removing from the surface of a body of water a lighter contaminant liquid

In practice it is often necessary to remove from the surface of the sea contaminating liquids of different nature which having less density than the water The problem is especially acute in eliminating from the surface of the sea contaminant liquids of an oily nature where the problem arises particularly in proximity to ports and may be caused by oil discharge from ships and by the washing-out operation of the holds of tankers It is also necessary with every increasing frequency to work on the open sea due to oil spillage accidents or wrecks involving tankers In such situations it is desirable to use a vessel for removing the contaminant liquid which is both seaworthy and able to reach the contaminated area with sufficient speed

Many systems have been adopted hitherto in order to attempt to solve the abovementioned problems One widely known procedure which has been used is based upon the use of chemical solvents capable of dissolving the contaminating liquid The resulting solution having a greater density than that of the water sinks to the bottom of the sea However such a procedure has the serious disadvantage of greatly damaging the marine fauna and destroying the flora on the sea bed itself Other known systems are based upon introduction into the interior of the hull of a floating vessel of the surface layers of the water to be purified and upon successive separation of the contaminant liquid from the water Such systems have the disadvantage of having to introduce and cause to flow inside the vessel together with the contaminant liquid a considerable quantity of water which inevitably leads to the vessel being unsuitable for use in the open sea and having very much reduced efficiency if used in rough seas the vessel also having a slow speed of movement even under nonworking conditions An object of the present invention is to obviate the above-cited disadvantages

SUMMARY OF THE INVENTION

Accordingly the present invention provides a system of removing from the surface of a body of water a contaminant liquid of lower density than the water the system comprising conveying surface layers of the body of water into an inverted channel immersed in the water and having its upper surface at a level lower than the free surface of the body of

water forming in the upper part of the inverted channel through the formation of vortices axially spaced apart zones for the accumulation of the contaminant liquid applying suction to said accumulation zones for the purpose of withdrawing the contaminant liquid accumulated therein and conveying it into decantation or settling tanks

The present invention also provides a vessel for use in removing from the surface of a body of water a contaminant liquid of lower density than the water characterized in that the vessel comprises

at least two pontoons provided with tanks for the collection and decantation of the contaminant liquid

a hull extending between each pair of adjacent pontoons and having in transverse cross section a profile different points of which have different distances from the plane tangent to the bottoms of the pontoons

at least one inverted longitudinal channel formed by the hull in the or each zone of greatest distance from the said tangent plane means defining in the upper part of each inverted channel when the latter is completely immersed during forward movement of the vessel through surface contaminated water accumulation zones for the contaminant liquid in correspondence with apertures in a wall of the inverted channel and means for transferring into the collection and decantation tanks by the application of suction the liquid accumulated in the said accumulation zones of the inverted channels

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

Referring to the drawings a vessel 1 according to the invention comprises two lateral pontoons 2 joined together by a central hull 3 and surmounted by a cabin 4 The central hull 3 has a cylindrical forepart 3laquo which meets the upper deck of the vessel the remaining part of the central hull 3 has a V-profile in transverse section with its vertex facing downwards so that different points in the cross sectional profile of the bottom of the hull 3 have different distances from the plane HH tangent to the bottoms of the pontoons 2 This profile is symmetrical with respect to the longitudinal plane of symmetry of the vessel and defines in proximity to the connection of the central hull 3 to each of the lateral pontoons 2 a collection zone which is a greater distance from the said tangent plane HmdashH than the vertex of the hull 3 In each of the collection zones the central hull 3 forms an inverted channel 5 extending longitudinally over the greater part of the length of the vessel The hull 3 has a series of fishbone ribs 33 the vertices of which point forwardly The ribs 33 act as deflectors guiding the liquid which flows over the bottom surface of the central hull 3 towards the two channels 5

The internal wall 7 of each lateral pontoon 2 which forms the outer boundary of the respective inverted channel 5 is provided with a plurality of rectangular apertures 6 in the upper zone of said inverted channel 5 The apertures 6 open into a manifold 8 disposed inside the adjoining pontoon 2 parallel to the inverted channel 5 and having a length substantially equal to that of the said inverted channel

The part of the central hull 3 which constitutes the top of each inverted channel 5 is provided with apertures 9a disposed in correspondence with the respective apertures 6 Each aperture 9a communicates with a vertical conduit 9 which opens into the atmosphere through a narrow ventilator opening 9b facing rearward and situated on the upper deck of the vessel 1

Each inverted channel 5 is furnished with a plurality of longitudinal fins 10 extending throughout the entire length of the channel 5 The fins 10 extend in height from the bottom of the channel 5 as far as the lower edges of the apertures 6 Perpendicularly to the longitudinal fins 10 there are disposed a plurality of main transverse fins 11 extending over the entire width and entire height of each inverted channel 5 Between each pair of successive transverse deflector fins 11 there are provided a plurality of auxiliary transverse deflector fins 12 also extending over the entire width of the inverted channel 5 but not extending over the entire height of the channel more specifically between the edges of the auxiliary fins 12 and the top of the said inverted channels there is provided a

flow passage 12a The transverse fins 11 and 12 are upwardly inclined with respect to the direction of advance of the vessel 1 in the water as indicated in FIG 5 by the arrow F and give rise to vortices in the liquid as the vessel advances so as to trap the contaminant liquid in the respective channels 5 as hereinafter described

The manifold 8 communicates through a conduit 13 with a plurality of decantation tanks 14 communicating with each other through apertures 16 and 15 formed respectively in the lower part and in the upper part of said tanks A decantation pump 18 draws off through a conduit 17 the liquid accumulated in the tanks 14 and conveys it through a conduit 19 into a slow settling tank 20 closed at the top and communicating at the bottom with the tanks 14 through an aperture 21 A discharge pump 22 withdraws liquid from the lower zone of the tanks 14 through a conduit 23 and discharges it into the surrounding water through a discharge conduit 24 Each lateral pontoon 2 has an aft buoyancy tank 25 and a forward buoyancy tank 26

FIG 3 shows at LN the level of the free surface of water under normal navigation conditions of the vessel and at LF the level of the free surface of the water under conditions of use of the vessel in which it removes contaminant liquid from the surface of the water

The manner of operation of the vessel previously described is as follows When the vessel is under way the decantation containers 14 are partially empty and consequently the central hull 3 is completely clear of the water Under such conditions the vessel 1 is able to move quickly and proceed to the operating zone Once the vessel reaches the operating zone a pump mdashnot shownmdash fills the decantation tanks 14 so that the vessel sinks up to the operating level LF In this situation the upper wall of each inverted channel 5 lies at a depth A FIG 3) which is dependent on the dimensions of the vessel 1 for example for a vessel 1 having a length between 12 and 15 meters the depth A varies between 30 md 50 cms the latter depth being adopted when the vessel 1 is used in rough seas

The forward motion of the vessel 1 relative to the surrounding water thrusts the surface layers of the water having regard to the profile of the underside of the central hull 3 and the inclination of the ribs 33 into the two inverted channels 5 disposed at the two sides of the hull 3 In each inverted channel 5 the surface layers are deflected towards the upwardly inclined deflector fins 11 and 12 The contaminant liquid being lighter tends to rise and remains trapped in the upper zones of the inverted channels 5 between the successive deflector fins 11 Such upper zones constitute therefore accumulation zones for the contaminant liquid When the pump 22 is put into operation suction is applied to the inside of the tanks 14 and through the conduit 13 to the manifold 8 The contaminant liquid in the accumulation zones of the inverted channels 5 is drawn through the apertures 6 into the manifolds 8 the apertures 6 being each positioned immediately downstream of upper ends of the deflector fins 11 The contaminant liquid trapped between the fins 11 is thus

drawn through the manifolds 8 into the tanks 14 The auxiliary deflector fins 12 facilitate the circulation of the contaminant liquid towards the apertures 6 in the accumulation zones

The lighter contaminant liquid collects in the upper parts of the tanks 14 whilst the water is collected in the lower parts of the tanks and is discharged into the surrounding water by the pump 22 through the conduit 23 and the discharge conduit 24 The tanks 14 are thus refilled progressively with contaminant liquid

For the purpose of obtaining more efficient separating or decanting action the decantation pump 18 withdraws liquid from the upper parts of the tanks 14 and decants it to the interior of the slow settling tank 20 which is closed in its upper region whilst its bottom region is connected through the aperture 21 to the tanks 14 The tanks 14 and the slow settling tank 20 are provided with vents (not shown) in their upper walls for the escape of trapped air

The slow settling tank 20 being watertight permits the accumulation in its upper part of contaminant liquid even when the vessel 1 is operating in a rough sea It will be noted that even under these conditions the concentration of the contaminant liquid in the accumulation zones is substantial given the tendency of that liquid being lighter than the water to rise in the tanks 14 The contaminant liquid therefore becomes trapped in the accumulation zones comprised between the deflector fins 11 from which zones subsequent dislodgement of the said liquid would be difficult notwithstanding the vortex action in the water underneath these zones The longitudinal fins 10 also serve to smother such turbulence and vortex action in the accumulation zones

The use of the vessel 1 is continued until total refilling with the contaminant liquid of the settling tank 20 and almost total refilling of the tanks 14 has occurred At this point the operation of the vessel 1 is ceased

In the variant illustrated diagrammatically in transverse cross section in FIG 7 the central hull of the vessel shown at 333 has an inverted V-profile with its vertex facing upwards having therefore a single central zone of maximum distance from the plane HmdashH tangent to the bottoms of the pontoons 2 A single inverted channel 5 is arranged in this central zone of the hull 333

It will be appreciated that constructional details of practical embodiments of the vessel according to the invention may be varied widely with respect to what has been described and illustrated by way of example without thereby departing from the scope of present invention as defined in the claims Thus for example the vessel may be equipped with three or more pontoons and the profile of the hull between each pair of pontoons could be of different form from the V-shaped profile of the illustrated embodiments

9 Claims 9 Drawing Sheets

The present invention relates to a waterborne vessel with an oxygenation system which decontaminates surrounding water and a method therefor

Ozone (03) is one of the strongest oxidizing agents that is readily available It is known to eliminate organic waste reduce odor and reduce total organic carbon in water Ozone is created in a number of different ways including ultraviolet (UV) light and corona discharge of electrical current through a stream of air or other gazes oxygen stream among others Ozone is formed when energy is applied to oxygen gas (02) The bonds that hold oxygen together are broken and three oxygen molecules are combined to form two ozone molecules The ozone breaks down fairly quickly and as it does so it reverts back to pure oxygen that is an 02 molecule The bonds that hold the oxygen atoms together are very weak which is why ozone acts as a strong oxidant In addition it is known that hydroxyl radicals OH also act as a purification gas Hydroxyl radicals are formed when ozone ultraviolet radiation and moisture are combined Hydroxyl radicals are more powerful oxidants than ozone Both ozone and hydroxyl radical gas break down over a short period of time (about 8 minutes) into oxygen Hydroxyl radical gas is a condition in the fluid or gaseous mixture

Some bodies of water have become saturated with high levels of natural or man made materials which have a high biological oxygen demand and which in turn have created an eutrophic or anaerobic environment It would be beneficial to clean these waters utilizing the various types of ozone and hydroxyl radical gases

decontaminating that defined volume of flowing water prior to further mixing with other water subject to additional oxygenation in the waterborne vessel

It is an additional object of the present invention to provide a mixing manifold to mix the ozone independent with respect to the hydroxyl radical gas and independent with respect to atmospheric oxygen and wherein the resulting oxygenated water mixtures are independently fed into a confined water bound space in the waterborne vessel to oxygenate a volume of water flowing through that confined space

FIG 5 diagrammatically illustrates a side elevation schematic view of oxygenation system 12 and more particularly tunnel 14 of the waterborne vessel A motor 59 drives a propeller in propeller region 18 In a preferred embodiment when gills 16 are open (see FIG 6) propeller in region 18 creates a flow of water through tunnel 14 of oxygenation system 12 A plurality of conduits 60 each independently carry either an oxygenated water mixture with ozone or an oxygenated water mixture with ozone plus hydroxyl radical 65 gases or an oxygenated water mixture with atmospheric oxygen These conduits are vertically and laterally disposed with outputs in an array at the intake 64 of the tunnel 14 A plurality of baffles one of which is baffle 66 is disposed downstream of the conduit output ports one of which is output port 61A of conduit 60A Tunnel 14 may have a larger number of baffles 66 than illustrated herein The baffles create turbulence which slows water flow through the tunnel and increases the cleaning of the water in the tunnel with the injected oxygenated mixtures due to additional time in the tunnel and turbulent flow

FIG 6 diagrammatically shows a schematic top view of oxygenation system 12 The plurality of conduits one of 10 which is conduit 60A is disposed laterally away from other gaswater injection ports at intake 64 of tunnel 14 In order to supersaturate a part of the water flow a diversion channel 70 is disposed immediately downstream a portion or all of conduits 60 such that a portion of water flow through tunnel 15 intake 64 passes into diversion channel 70 Downstream of diversion channel 70 is a reverse flow channel 72 The flow is shown in dashed lines through diversion channel 70 and reverse flow channel 72 The primary purposes of diversion channel 70 and reverse flow channel 72 are to (a) segregate a 20 portion of water flow through tunnel 14 (b) inject in a preferred embodiment ozone plus hydroxyl radical gas as well as atmospheric oxygen into that sub-flow through diversion channel 70 and (c) increase the time the gas mixes and interacts with that diverted channel flow due to the extended 25 time that diverted flow passes through diversion channel 70 and reverse flow channel 72 These channels form a super saturation channel apart from main or primary flow through tunnel 14

Other flow channels could be created to increase the amount of time the hydroxyl radical gas oxygenated water mixture interacts with the diverted flow For example diversion channel 70 may be configured as a spiral or a banded sub-channel about a cylindrical tunnel 14 rather than configured as both a diversion channel 70 and a reverse flow channel 35 72 A singular diversion channel may be sufficient The cleansing operation of the decontamination vessel is dependent upon the degree of pollution in the body of water

surrounding the vessel Hence the type of oxygenated water and the amount of time in the tunnel and the length of the tunnel and the flow or volume flow through the tunnel are all factors which must be taken into account in designing the decontamination system herein In any event supersaturated water and gas mixture is created at least the diversion channel 70 and then later on in the reverse flow channel 72 The extra time the 45 entrapped gas is carried by the limited fluid flow through the diversion channels permits the ozone and the hydroxyl radical gas to interact with organic components and other compositions in the entrapped water cleaning the water to a greater degree as compared with water flow through central region 76 50 of primary tunnel 14 In the preferred embodiment two reverse flow channels and two diversion channels are provided on opposite sides of a generally rectilinear tunnel 14 FIG 4A shows the rectilinear dimension of tunnel 14 Other shapes and lengths and sizes of diversion channels may be 55 used

When the oxygenation system is ON gills 16 are placed in their outboard position thereby extending the length of tunnel 14 through an additional elongated portion of vessel 10 See FIG 1 Propeller in region 18 provides a propulsion system 60 for water in tunnel 14 as well as a propulsion system for vessel 10 Other types of propulsion systems for vessel 10 and the water through tunnel 14 may be provided The important point is that water flows through tunnel 14 and in a preferred embodiment first second and third oxygenated water mixtures (ozone + pressurized water ozone + hydroxyl radical gas + pressurized water and atmospheric oxygen + pressurized water) is injected into an input region 64 of a tunnel which is disposed beneath the waterline of the vessel

In the preferred embodiment when gills 16 are closed or are disposed inboard such that the stern most edge of the gills rest on stop 80 vessel 10 can be propelled by water flow entering the propeller area 18 from gill openings 80A 80B When the gills are closed the oxygenation system is OFF

FIG 7 diagrammatically illustrates the placement of various conduits in the injector matrix The conduits are specially numbered or mapped as 1-21 in FIG 7 The following Oxygenation Manifold Chart shows what type of oxygenated water mixture which is fed into each of the specially numbered conduits and injected into the intake 64 of tunnel 14

As noted above generally an ozone plus hydroxyl radical gas oxygenated water mixture is fed at the forward-most points of diversion channel 70 through conduits 715171 8 and 16 Pure oxygen (in the working embodiment atmospheric oxygen) oxygenated water mixture is fed generally downstream of the hydroxyl radical gas injectors at conduits 30 19 21 18 20 Additional atmospheric oxygen oxygenated water mixtures are fed laterally inboard of the hydroxyl radical gas injectors at conduits 6 14 2 9 and 10 In contrast ozone oxygenated water mixtures are fed at the intake 64 of central tunnel region 76 by conduit output ports 5431312 and 11 Of course other combinations and orientations of the first second and third oxygenated water mixtures could be injected into the flowing stream of water to be decontaminated However applicant currently believes that the ozone oxygenated water mixtures has an adequate amount of time to 40 mix with the water from the surrounding body of water in central tunnel region 76 but the hydroxyl radical gas from injectors 7 15 17 1 8 16 need additional time to clean the water and also need atmospheric oxygen input (output ports 19 21 8 20) in order to supersaturate the diverted flow in diversion channel 70 and reverse flow channel 17 The supersaturated flow from extended channels 70 72 is further injected into the mainstream tunnel flow near the tunnel flow intake

Further additional mechanisms can be provided to directly inject the ozone and the ozone plus hydroxyl radical gas and the atmospheric oxygen into the intake 64 of tunnel 14 Direct gas injection may be possible although water through-put may be reduced Also the water may be directly oxygenated as shown in FIG 4C and then injected into the tunnel The array of gas injectors the amount of gas (about 5 psi of the outlets) the flow volume of water the water velocity and the size of the tunnel (cross-sectional and length) all affect the degree of oxygenation and decontamination

Currently flow through underwater channel 14 is at a minimum 1000 gallons per minute and at a maximum a flow of 1800 gallons per minute is achievable Twenty-one oxygenated water mixture output jets are distributed both vertically (FIGS 4A and 5) as well as laterally and longitudinally (FIGS 6 and 7) about intake 64 of tunnel 14 It is estimated 65 that the hydroxyl radical gas needs about 5-8 minutes of reaction time in order to change or convert into oxygen Applicant estimates that approximate 15-25 of water flow is diverted into diversion channel 70 Applicant estimates that water in the diversion channel flows through the diverters in approximately 5-7 seconds During operation when the oxygenation system is operating the boat can move at 2-3 knots The vessel need not move in order to operate the oxygenation 5 system

FIG 8 shows an alternative embodiment which is possible but seems to be less efficient A supply of oxygen 40 is fed into an ozone generator 44 with a corona discharge The output of ozone gas is applied via conduit 90 into a chamber 92 Atmospheric oxygen or air 94 is also drawn into chamber 92 and is fed into a plurality of horizontally and vertically

disposed nozzles 96 Manifold 98 consists of a plurality of oxygenation nozzles 96 Manifold 98 can be raised or lowered by any appropriate means In the illustrated embodiment rotating 15 threaded sleeve 110 operates on threaded rod 112 to raise and lower oxygenation manifold 98 Diverter blade 22 can be raised and lowered by another mechanism generally shown as lifting mechanism 24 in FIG 1 Shaft 114 drives propeller 116 to provide a propulsion system to move water through 20 tunnel 118 FIG 8A shows that the water propulsion system to move the water through the tunnel could be forward the tunnel intake 64 shown in FIG 6 The alternative embodiment also shows that the tunnel may be foreshortened

FIG 8B is a detail showing gas injection nozzle 96 and 25 water flow 120 passing through restricted flow channel 122

FIG 9 diagrammatically shows that diversion blade 22 when rotated downward as shown by arrow 142 directs oxygenated and treated water output 144 the oxygenation systems into lower depths of the body of water being treated by 30 vessel 10

FIG 10 diagrammatically illustrates aeration injector manifold 98

FIG 11 shows aeration injectors 96 having a forward inverted V shaped body 160 and a rearward generally oval 35 shaped body 162 Air plus ozone is pumped or drawn into the interior region 164 of V shaped body 160 Water flow is directed through constricted channel 122 and a high degree of turbulence in region 166 mixes the ozone with the water flow through constricted channel 122 This turbulence in restricted 40 flow channel 122 causes the ozone and atmospheric oxygen to mix with the water flow thereby oxygenating the water

FIG 12 shows a pressurized gas system which has been described earlier
