Definitions

  • This invention relates to a marine structure for the underwater storage of oil in offshore areas, and is a further development of the subject matter disclosed in our earlier-filed copending application Serial No. 848,- 466, entitled Offshore Storage Unit.
  • the present invention comprises a compartmented hull with columns extending upwardly therefrom and adapted to project above the surface of the water when the hull is stably supported adjacent the marine oor.
  • Platforms at the tops of these columns support production equipment, oil treating equipment and similar apparatus.
  • the structure can be floated to location on the buoyancy of the hull, and is set up on location by ooding said hull, stability being maintained by means of the columns. Thereafter, through oil piping communicating between the production platform and the columns and hull compartments, storage and discharge of oil is effected. When it is desired to relocate the structure, the same can be refloated by suitably deballasting the hull and columns.
  • One of the objects of this invention is to provide safe and efficient means for the storage and discharge of oil in offshore areas.
  • Another object of this invention is to provide a structure for the storage and discharge of oil in offshore areas, which structure can be floated to location, set up in a short period of time, and retloated in a short period of time for use at another site.
  • a further object of this invention is to provide a structure for the storage and discharge of oil in offshore areas, which structure will be stable in all kinds of weather, whether aoat or aground.
  • FIG. l represents a diagrammatic view in perspective of our underwater storage unit, and shows the various compartments and piping according to our invention.
  • FiG. 2 represents an enlarged vertical median section of the water receiver of the present invention.
  • FIG. 3 represents a section in plan of the water receiver of the present invention, taken along the line 3 3 of FIG. 2.
  • FIG. 4 represents a section in plan of the water lines and the column in which they pass, and shows the individual sinking connections communicating with the water lines and extending outside the column.
  • the invention is seen to comprise a liquid-tight hull 1, provided with liquid-tight bulkheads 2, 3, 4 and 5, subdividing said hull 1 into corner compartments 6, 7, 8 and 9 and central compartment 1t).
  • Liquid-tight columns 11, 12, 13 and 14, communicating with corner compartments 6, 7, 8 and 9 respectively, are secured to hull 1, extending upwardly therefrom, and are of length sufficient to project well above the surface of the water when said hull is stably supported adjacent, as by contact with, the marine floor.
  • Production platform 15 the walls of which define liquid-tight settling tank 16, is supported on column 11.
  • Oil receiver 17 is mounted on production platform 15 and communicates through conduit means 1S and 19 with the upper portion of settling tank 16, said conduit means 18 and 19 preferably extending into the upper portion of said oil receiver 17 so as to constitute an overflow weir.
  • Settling tank 16 is provided with oil inlet connections 20 and 21 which may communicate with a source of oil and, preferably, which source may be an oil-water separator (not shown) which may be mounted on the production platform 15.
  • Settling tank 16 may be compartmented so that, for instance, oil inlet connection 20 and conduit means 18 communicate with one such compartment and oil inlet connection 21 and conduit means 19 communicate with another such compartment.
  • Such compartmentation being familiar to those acquainted with the art, the same is not shown in FIG. l as it would make the latter more difficult to read.
  • oil may be conducted between the lower portion of oil receiver 17 and the upper portion of the space or volume defined by corner compartment 7 and that portion of column 12 lying below bulkhead 30 through oil conduit means 28 and 31, between the lower portion of oil receiver 17 and the upper portion of the space or volume defined by corner compartment 6 and that portion of column 11 lying below bulkhead 22 through oii conduit means 28 and 32, between the lower portion of oil receiver 17 and the upper portion of the space or volume defined by corner compartment 9 and column 14 through oil conduit means 28 and 33, and between the lower portion of oil receiver 17 and the upper portion of the space or volume defined by corner compartment 8 and column 13 through. oil conduit means 28, 33 and 34 and the upper portion of column 14.
  • Two tanker loading stations 35 and 36 are provided, one on either side of the Underwater Storage Unit, either or both of which may be used at any one time, through oil discharge conduit means 37 and 38, with valved connections 39 and 40 therein respectively, to which hose lines 41 and 42 from the tankers may be secured.
  • either or both loading stations 35 and 36 may be placed in communication with oil conduit means 31, 32, 33 and 34 and thus with the upper portion of the space or volume defined by corner compartment 7 and that portion of column 12 lying below bulkhead 30, with the upper portion of the space or Volume defined by corner compartment 6 and that portion of column 11 lying below bulkhead 22, with the upper portion of the space or volume defined by corner compartment 9 and column 14, and with the upper portion of the space or volume defined by corner compartment 8 and column 13.
  • Through oil conduit means 45, with valve 46 therein, either or both loading stations 35 and 36 may be placed in communication with the upper portion of oil compartment 23.
  • Through oil conduit means 28 either or lboth loading stations 35 and 36 may be placed in communication with the lower portion of oil receiver 17.
  • either'or both loading stations 35 and 36 may be placed in communication with the upper portions of the several oil storage 4spaces or volumes in the structure through oil conduit means 47, with valve 48 therein, communicating between the -upper portion of column 14 and oil discharge conduit ⁇ means 38, as will be evident upon inspection of FIG. 1.
  • Either or-both loading stations 35 and 36 may be placed in communication with settling tank 16 of production platform 15 through oil conduit means 49 with valve 50 therein. If said tank 16 is compartmented, then each of said compartments will beprovided with its own oil conduit means 49 and valve 50.
  • Air from central compartment 10 will pass through trunk V27, oil conduit means 26, oil compartment 23, oil conduit means 24 to oil receiver 17 and thence to the vatmosphere through said combination pressure-vacuum relief valve 51. It will be apparent that settling tank 16 vents through oil conduit means 18 and 19 to oil receiver 17 and valve 51.
  • Pressure-vacuum relief valve 51 performs several important functions. -It permits venting as previously described. When set to vent slightly above atmospheric pressure, it permits a slight pressure on the oil in the ⁇ structure and thereby reduces volatilization of the oil which otherwise would occur at atmospheric pressure under certain conditions of temperature.
  • the vacuum feature of valve 51 provides a minimum pressure on the oil contents of the structure thereby preventing excessive ashing orvaporization of the oil which otherwise would occur under certain conditions of temperature if the pressure fell too much.
  • the pressure-vacuum relief valve- is set for 4 oz. p.s.i.g. pressure and 1/2 oz. p.s.i.g. vacuum.
  • Water conduit means 55 communicates between Vthe surrounding water and the suction-inlet of water pump 56.
  • Water conduit means 57 communicates between the discharge outlet of water pump156 andthe upper portion of -water receiver 53, ex tending through the bottom A54 of the pump platform 52 as shownlin FIG. A2.
  • Water conduit means 58, 59, 60, 61 and62, extending through bulkhead 30, communicate between the lowerv portion of water receiver 53-and the lower portions of corner compartments, 7, 8 and 9 and central compartment 10, respectively, through funnel fittings 63.
  • Water receiver 53 is lprovided adjacent its upper portion at a predetermined/height, for a purpose which will be explained further on, with an overflow 64 acting as a weir and communicating with overflow conduit means 65, the latter being open at'the top 66 Vfor venting itself and being open at the bottom 67 and adjacent thereto provided with a multiplicity of perforations 68 for diffusion.
  • the Underwater Storage Unit is operated on hydraulic displacement principles and, in connection therewith, water and oil will at various times be in contact at an interface. As a result, it may happen that some oil will be entrained in the water. As will be explained further on, water overows water receiver 53 through overow 64 and is discharged through overflow conduit means to the surrounding body of water. There arises the problem of avoiding pollution of the surrounding water by entrained oil, it being almost invariably the case that :anti-pollution laws apply. The magnitude of this problem can readily be appreciated when it is considered that, in one jurisdiction, such pollution cannot lawfully exceed 5 parts per million of oil in water. Also, excessive oil in the surrounding area can create a serious iirehazard.
  • the water receiver 53 of the present invention is provided with plate barks 69 and 70 dividing said water receiver 53 into threechambers 71, 72 and 73.
  • Pipe 74 closed at its upper end by plate 75, communicates between the lower portion of chamber 71 ⁇ and chamber 72 through conduit 76 extending th-rough plate baffle 69.
  • Chamber 72 communicates, beneath the lower edge of plate bafde 70, with chamber 73, the latter being closed ⁇ at the top by plate 77 and communicating with overflow 64.
  • the level of the water in water receiver 53 will generally be -at the approximate position of line 78.
  • skim suction conduit 79 Any entrained oil will separate out and rise to the top of chamber 71, whence said oil will be withdrawn by skim suction conduit 79, the latter being connected to a suitable source of suction. Any small remaining quantity of entrained oil carried over to chamber 72 will rise to the top thereof and will not carry over to chamber 73 as communication with the latter is through the lower portion of chamber 72.
  • Water receiver 53 is, additionally, provided with vent conduit 80 which may lead to a combination pressurevacuum relief valve 81, and with valved drain 82.
  • Valve 81 performs substantially the same functions within water receiver 53 as valve 51, and in the preferred embodiment, is set for the same values of pressure and vacuum.
  • sinking connections 85, 86, 87, 88 and 89 connected to water conduit means 58, 59, 60, 61 and 62 respectively, and extending outside the Wall of column 12 at an elevation which will remain above the level of the surrounding water when the structure is finally stably supported adjacent the marine floor.
  • sinking connections will be closed as by blank anges 90, 91, 92, 93 and 94 respectively.
  • compressed air may be introduced into such spaces or volumes to displace the water therefrom to the water receiver 53 and thence through overflow 64 to the surrounding water.
  • compressed air connections 95 and 96 and spectacle flange 97 are provided in oil conduit means 34
  • spectacle ange 98 is provided in oil conduit means 33
  • compressed air connections 99 and 100 and spectacle flange 101 are provided in oil conduit means 31, and compressed air connection 102 is provided in oil conduit means 24.
  • valve means may be used but, in any event, when the compressed air connections 95, 96, 99, and 102 are not in use, the same must be closed and spectacle flanges 97, 98 and 101 or the equivalent valve means must be open.
  • Platforms are mounted on columns 13 and 14, in similar manner as platforms 15 and 52 on columns 11 and 1-2 respectively, and may be used fora heliport and crews quarters. In any event, all of the valves and various fittings are accessible from the platforms mounted to the several columns, except for sinking connections 85, 86, 87, 88 and 89, and :these latter will be accessible from ladders and walkways (not shown) mounted to column 12.
  • Blank flanges 90, 91, 92, 93 and 94 are removed from sinking connections 85, 86, 87, 88 and 89, and hose lines from water pumps on an auxiliary vessel moored alongside are connected to said sinking connections 85, 86, 87, 88 and 89 and water pumped therein to ballast, respectively, the space or volume defined by corner compartment 6 and that portion of column 11 lying below bulkhead 22, the space or volume defined by corner compartment 7 and that portion of column 12 lying below bulkhead 30, the space or volume defined by corner compartment 8 and column 13, the space or volume defined by corner compartment 9 and column 14, and central compartment 10, the air from said spaces or volumes venting out through pressure-vacuum relief valve 51 as previously described, valves 25 and 29 being open for this purpose.
  • central compartment 10 has been so proportioned that, when it is filled with ballast water, the structure will float with about one foot of freeboard and, in the initial sinking operation of said preferred embodiment, the central compartment 10 will be filled with ballast water first and thereafter, the remaining spaces or volumes of hull 1 will be ballasted to complete the sinking operation.
  • This method results in the elimination of the large free surface effect of water ballast in central compartment 10 before the water plane thereof is lost.
  • the structure may be kept under control during the sinking operation by regulating the flow of ballast water to the several volumes or spaces being ballasted.
  • the hose lines are removed, and blank flanges 90, 91, 92, 93 and 94 are reinstalled on sinking connections 85, 86, 87, 88 and 89 respectively.
  • Oil may now be introduced into settling tank 16 through oil inlet connections 20 and 21.
  • oil conduit means 18 and 19 When settling tank 16 is full, the oil will rise in oil conduit means 18 and 19 and will overow into oil receiver 17.
  • oil receiver 17 is at a level considerably higher than the level of overiiow 64 in water receiver 53, and the ratio of the height of oil receiver 17 above the marine floor to the height of overflow 64 above the marine fioor is greater than the ratio of salt water density to oil density.
  • oil will iiow from oil receiver 17 through oil conduit means 28 and 31 to that portion of column 12 lying below bulkhead 30, through oil conduit means 28 and 32 to that portion of column 11 lying below bulkhead 22, through oil conduit means 28 and 33 to the upper portion of column 14, through oil conduit means 28, 33 and 34 to the upper portion of column 13, and through oil conduit means 24, oil compartment 23, and oil conduit means 26 to central compartment 10, the water displaced from said spaces or volumes passing through water conduit means 59, 58, 61, 60 and 62 respectively into water receiver 53, in which any entrained oil settles out as previously described, and thence out through overflow 64 and overflow conduit means 65 to the surrounding water.
  • corner compartment 7 and that portion of column 12 lying below bulkhead 30, corner compartment 6 and that portion of column 11 lying below bulkhead 22, corner compartment 9 and co1- umn 14, corner compartment 8 and column 13, and central compartment 10 will gradually fill with oil, it being understood that unless tankers are at the same ⁇ time loading at either or both loading stations 35 and 36, valves 44, 50, 39, 46, 40 and 48 will normally be closed.
  • a high level float shutoff 103 is provided and which functions by means of a piping and control system (not shown, but understood by those familiar with the art) to shut off the flow of oil into oil inlet connections 20 and 21.
  • Tankers may be loaded at either or both loading stations 35 and 36, after the structure has been filled with oil or while :the structure is being filled with oil.
  • the tankers are moored alongside columns 12 and/ or 14, and hose lines 41 and/or 42 from said tankers are connected to valved connections 39 and 40 respectively.
  • Valved connections 39 and 40 are opened or closed depending upon whether one or both loading stations or one loading station are in use, and if the latter, then upon which loading station is in use, as will be evident to those familiar with the art.
  • Valves 44, 46, 4S, 29 and 25 are open. Oil in oil receiver 17 will then iiow by gravity to the tanker or tankers, and water pump 56 is operated to introduce Water into water receiver 53.
  • the contents of settling tank 16 can be drained to either loading station as part of the preceding operation or as a separate operation through oil conduit means 49 when valve 50 is open.
  • Water receiver 53 performs a very important function in the preceding operation, viz., displacing oil by water, in that it provides an air gap between the water pump and the several oil storage volumes or spaces thus positively preventing overpressure and consequent rupture of the plating of such volumes or spaces or bursting of seams therein. In conventional designs, such overpressure could result from some of the valves in the oil lines being closed inadvertently.
  • the air gap provided by the Water receiver 53 permits an absolute, predetermined limit to be placed on the amount of internal pressure in the present invention, as water pump 56 is not directly hydraulically coupled to the said apparatus, said predetermined limit being absolutely foolproof and not subject to malfunctioning of any kind.
  • Water receiver 53 performs another important function in the preceding operation in that it provides a constant hydrostatic head on the body of oil and thereby carryover of displacing water to the tankers is prevented.
  • the water pump is directly hydraulically coupled to the system, surging, turbulenece and eddying of the displacing water in the body of oil to be displaced would result in some of the ,displacing water passing to the tanker vessel along with the displaced oil.
