Definitions

  • the invention relates to how the side plating of a vessel intended for carrying cold liquid substances is protected against spills or splashes of a cold liquid substance occurring in the process of loading and unloading the vessel, and against damage resulting therefrom.
  • cold liquid substances refers to liquid substances whose shipping, storage and/or transfer temperature is below -50°C.
  • This tem- perature of -50°C is critical from the standpoint of vessel structures, since structural steel used in shipbuilding and intended for cold conditions can be expected to have resistance up to this temperature. In other words, at temperatures lower than -50°C, the ship structures may possibly develop cold embrit- tlements and fractures.
  • other metals or steel grades such as aluminum or alloy steels rich in nickel, can be used, but these are more expensive and involve i.a. welding and corrosion problems in use.
  • Typical cold liquid substances include for example cryogenic liquids, which are typically liquefied gases with a boiling point typically lower than -150°C.
  • cryogenic liquids which are typically liquefied gases with a boiling point typically lower than -150°C.
  • Other examples of cold liquid substances include i.a. liquid ethylene (shipping temperature about -104°C), liquid nitrogen (shipping temperature about -196°C) and liquid oxygen (shipping temperature about -182°C).
  • the cold liquid substance is loaded in and unloaded from a vessel's tanks by pumping liquid through piping manifolds and hoses. It is obvious that components, which normally come into contact with cold liquid, are manufactured from materials with properties appropriate for such contact. Piping manifolds used in the unloading and loading of a vessel are typically constructed and laid out in view of enabling the piping manifolds of an unloading or loading terminal to be connected therewith at a specific location in the vessel's side plating area, said connection point being typically located in the vessel's lengthwise middle section.
  • the hull of such a vessel makes up a girder type structure, wherein the deck and the side are critical load-bearing elements nearly always under stress. Protecting those against excessive mechanical or thermal stresses is important.
  • the water curtain refers to running water in a continuous supply across the connection area of piping manifolds along a vessel's side plating from a top edge of the vessel's side structure, whereby the running water provides an unbroken curtain that flushes the vessel's side plating.
  • the water curtain prevents the vessel's side structure from making contact with splashes of cold liquid possibly colliding therewith, thus avoiding the occurrence of cold damage in the structure.
  • the solution according to the present invention enables elimination of the foregoing problems, as well as protection for a vessel's side plating from splashes of a cold liquid substance and from resulting cold embrittlement and damage.
  • the side plating of a vessel said vessel compris- ing at least one tank for storing a cold liquid substance
  • the connection area for vessel piping manifolds and port piping manifolds used in the transfer of a cold liquid substance, by means of a material layer which is mounted either fixedly or removably on the vessel's structure in the side plating area of the vessel, and which is constructed of a solid material.
  • a vessel of the invention be preferably equipped with an apparatus capable of providing a water curtain for this area of the vessel's side plating, thus enabling also the use of a water curtain in ports that do not have problems related to the use of a water curtain in cold climate.
  • the use of a water curtain, along with a material cover that protects the side plating of a vessel enhances the protection performance of a solution according to the invention in the event of cold liquid substance splashes.
  • the material cover permanently fastened to a vessel's structure is preferably made up of one or more adjoining layers of sheet metal capable of withstanding the temperature of a cold liquid substance, said material layer having been secured by welding to the vessel's side plating.
  • Such metal sheets are for ex- ample metal sheets made of stainless steel, particularly austenitic stainless steel.
  • the metal material layer welded to a vessel's side plating is preferably constructed in such a way that a first metal layer sheet is secured by welding the sheet along its edges to the attachment with the vessel's side and possibly al- so deck plating, as well as by welding within the sheet area at necessary points with plug welds.
  • the plug weld points present within the sheet area are in turn covered with smaller metal plates, which are welded along the edges thereof to the attachment with the first metal layer sheet. This enables the elim- ination of cold bridges possibly developing at plug weld points.
  • the metal sheets used in a material layer have preferably a thickness of 5-10 mm, more preferably 8-10 mm.
  • a suitable metal sheet thickness for various applications and side plating structures is obtained by optimizing the protective effect of a material thickness with respect to its adverse factors, such as for example the number of plug welds needed in attachment, as well as the motion resistance of a vessel caused by the material cover.
  • Another way of implementing a solution of the invention is the use of a removable material layer for protecting the side plating of a vessel in the connection area for vessel piping manifolds and terminal piping manifolds used in cold liq- uid substance loading and unloading operations.
  • the material layer mountable on a vessel's structure in a removable fashion is placed in the connection area of piping manifolds prior to unloading or loading the vessel's cargo and is removed after these operations.
  • the material layer to be removably mounted on a vessel's structure consists of a pliable material, which is capable of withstanding the temperature of a cold liquid substance, and which is secured along one edge to the vessel's structure for protecting the vessel's side plating, and along the other edge to the engagement with a port structure. Therefore, it is not absolutely necessary for the material layer to lie against a vessel's side plating for protective effect. Hence, the material layer can be held in storage as part of the port structure or stored in the vessel.
  • Such a removably attachable pliable material layer can be preferably constructed by using for example metal lamella strips flexibly attached to each other and made from stainless steel.
  • Other solutions capable of providing a flexible assembly are also possible, such as for example an assembly consisting of a scale pattern or overlapping lamella strips.
  • a material layer protecting the vessel's side plating can also be constructed from a suitable material other than stainless steel.
  • suitable ma- terial include i.a. aluminum and its alloys; a sandwich plate material with an intervening insulation or medium layer; a ceramic coating.
  • a material layer removably mounted on the vessel's side plating can also be constructed for example of wood, plywood or balsa; various plastic grades, such as for example Teflon-coated plastic; or a suitable waterproof fabric type material.
  • a material layer according to the invention mountable in the engagement with a vessel's side plating in a removable fashion, can also be constructed in such a way that the material layer is designed to be so-called “disposable", whereby, after the splashes or spills of a cold liquid substance have occurred, the material layer protects the vessel's side plating adequately, but after this situation the material panel must be replaced with a new one.
  • An example of such a solution is a two- or multiple-layered fabric material, having its external surface rendered waterproof for example with a Teflon coating, and underneath the waterproof layer is a thicker layer of some suitable, preferably fluffy insulation material, such as perlite or some other fluffy material.
  • Figure 1 shows schematically one protection solution of the invention mounted fixedly in the engagement with a vessel's side plating
  • Figure 2 shows schematically one protection solution of the invention mounted removably in the engagement with a vessel's side plating.
  • Figure 1 shows schematically part of a side plating 1 and a deck plating 2 for a vessel carrying some cold liquid substance, in a view of the area comprising connection points 4 for piping manifolds 3.
  • connection points 4 for the piping manifolds 3 are located in a vessel's lengthwise middle section, i.e. amidships.
  • a material layer 5 constructed of metal sheets.
  • the material layer 5 extends from a top edge of the side plating 1 vertically to level with or slightly below the lowest water level encountered during a loading operation.
  • the material layer 5 is designed to have a width in the longitudinal direction sufficient for protecting the side plating 1 , i.e. in other words, its width matches substantially for example the width of employed water curtains.
  • the material layer 5 is fastened to the side plating of a vessel by the edges of the material layer with welds 6, said welds preferably extending around the entire material layer along its edges, as well as within the material layer area with a suitable number of plug welds for ensuring immovability of the material layer, for example when the vessel is breaking ice.
  • a smaller metal plate 7 On top of each plug weld point is welded a smaller metal plate 7, which covers the plug weld point and thereby prevents the thermal effect of possible cold liquid substance splashes from advancing from the plug weld points to the vessel's side plating. Covering the plug weld points with separate metal plates 7 enables also the thickness of the material layer 5 to be minimized, whereby the thickness of the material layer does not significantly increase for example the ice breaking friction for the vessel.
  • the metal sheets employed in the material layer 5 are made of a suitable, onboard transportable metal capable of withstanding the temperature of a cold liquid substance, such as for example austenitic stainless steel.
  • the metal plates 7 welded on top of plug weld points consist preferably of the same metal as the rest of the material layer 5.
  • an apparatus for producing a prior known water curtain on an external surface of the material layer In this case, it is sufficient that the water curtain only be activated in the event of splashing to flush the external material layer surface. Hence, the material layer resistant to a cold liquid substance can be further re- raffled in thickness, thereby avoiding the drawbacks associated with continuous use of a water curtain in cold conditions.
  • Figure 2 shows schematically an example of a material layer 15 according to the invention, which is removably mounted in the engagement with a vessel's side plating 1 1 for protecting the side plating.
  • the material layer 15 is con- structed of a plurality of metal lamella strips 16 linked successively and pliable relative to each other, said metal lamella strips 16 preferably consisting of aus- tenitic stainless steel.
  • the material layer 15 is flexibly secured with chains 17 to a port structure by one end of the material layer, whereby, once a ship has arrived and been docked at a port, the other end of the material layer is hoisted for example by means of a crane to the engagement with the vessel's structure and secured in the example of fig. 2 to the vessel's deck structures 12 in the area of connection points 14 for the vessel's piping manifolds 13.
  • the material layer 15 has such a length which, once placed in its position, it extends from the point of attachment all the way below the water level.
  • the material cover 15 can be stored in the port preferably below the water level, such that the ice collecting thereon in Arctic conditions does not cause problems regarding the use and installation of the mate- rial layer.
  • the material layer 15 can be stored in a vessel, whereby, in the process of installing the material layer 15 in its active position, the material layer 15 is for example pulled out of the vessel and secured to port structures or the material cover 15 is lowered to conceal the vessel's side plating 1 1 .
  • What is most essential in these inventive ways of using the removably attachable material layers 15 is that the material layer is placed in its position to protect a vessel's side plating prior to or not later than simultaneously with the activation of cargo loading or unloading, and that the material layer is removed from its position protecting the side plating after these operations are complet- ed.
  • the removable material Iayer15 does not impede for example the vessel's motion.
  • the material cover can also be manufactured from some other appropriate material with a suffi- cient resistance to the temperature of a cold liquid substance.
  • examples of such materials are aluminum and its alloys, various sandwich materials, as well as ceramic coatings.
  • the material layer 15 can be constructed for example from wood or plastic lamellas fixed to each other in a pliable manner, or from a flexibility possessing material, such as plastic or a fabric material.
  • a flexible material enables the material layer 15 to be held in storage for example as a roll in the ship or in port, whereby the material layer can be conveniently pulled out between port and vessel to protect the vessel's side plating.
  • the material layer 15 can also be implemented as a disposable article, whereby the material layer protects a vessel's side plating from splashes of a cold liquid substance, but the material cover will have to be replaced after such an occurrence.
