Definitions

  • the present invention relates to a vessel, the hull of which takes an at least partially double-walled form, wherein a stiffening construction is arranged between the double walls of the hull.
  • Such a vessel is known in the art.
  • the stiffening construction of the known vessel consists largely of angle steels, so-called “Holland profiles" and/or of U.N.P. profiles of steel.
  • the invention has for its object to provide a vessel of the type stated in the preamble with a lighter stiffening construction.
  • the vessel according to the preamble has for this purpose the feature that the stiffening construction comprises a number of troughs which are connected fixedly to at least one of the walls.
  • Troughs are manufactured from sheet material and are therefore generally lighter than said angle steel and profiles, which in itself will result in a lighter stiffening construction.
  • the vessel according to the invention therefore has a greater cargo capacity or, if the load is the same, can achieve a higher sailing speed with the same engine power than the known vessel.
  • the troughs comprise longitudinal troughs which run at some mutual distance parallel to each other in longitudinal direction of the vessel. At least some of the longitudinal troughs are preferably endless. With the use of such longitudinal troughs the vessel acquires a greater strength in longitudinal direction.
  • one or more of the endless longitudinal trough s a substantially straight middle part which is bent at the position of the stem and/or the stern of the vessel at an angle such that the relevant end of the longitudinal trough makes contact with the middle part.
  • the angle is approximately 270°.
  • the troughs comprise transverse troughs which run at some mutual distance parallel to each other in transverse direction of the vessel.
  • the vessel according to the invention hereby acquires an improved stiffening in transverse direction.
  • the transverse troughs mutually connect at least some of the longitudinal troughs.
  • the transverse troughs preferably connect the longitudinal troughs in pairwise manner. If desired, a number of the transverse troughs is endless.
  • the troughs preferably comprise a light and strong steel type, preferably of the type also designated "Grade A" in the field.
  • the invention also relates to a method for stiffening the hull of a vessel, comprising the following steps of:
  • Figure 1 shows a longitudinal section through the hull of a vessel 1 according to the invention.
  • Figure 1 shows a longitudinal trough 2 which runs fore to aft over the whole length of vessel 1.
  • FIG 2 shows a cross-section through the hull 3 of the vessel of figure 1.
  • Hull 3 takes a double-walled form. Each wall has its own designation depending on the location on the vessel.
  • the lower bottom wall or surface 4 transposes on both sides via the chine 5 into the outer wall or skin 6. This skin runs via the deck 7 into the inner wall or bin wall 8.
  • the surface 4, chine 5, skin 6, deck 7 and bin walls 8 form the hull 3 of the vessel.
  • a stiffening construction which according to the invention comprises a number of troughs. These troughs comprise both longitudinal troughs 2 and transverse troughs 9 (see figure 4).
  • Longitudinal troughs 2 run substantially parallel to each other in longitudinal direction of vessel 1. A certain mutual distance is maintained between the longitudinal troughs. As shown in figure 1, at least a number of the longitudinal troughs is endless. This is also shown in figure 3, in which a schematic view, partly in cross-section, is shown along the line A-A' in figure 1.
  • Each of these endless longitudinal troughs consists of a middle part 10 running substantially parallel to surface 4. At the position of the stem and/or the stern of vessel 1 the longitudinal trough is bent at an angle such that the outer end 11 of the longitudinal trough makes contact with the middle part 10 thereof.
  • the longitudinal trough can for instance consist of a plurality of parts, as in the shown preferred embodiment.
  • Longitudinal trough 2 in figure 1 consists of a middle part 10 which is provided on both sides with two upward curving ends and a substantially horizontal second part 12 which runs parallel thereto and which is connected to part 10 by means of a third, substantially vertical part 13. For the sake of simplification only this connection is shown instead of the whole endless trough.
  • the angle between part 13 and part 10 is approximately 270°.
  • the trough parts are preferably welded to each other using known welding techniques. Application of such endless longitudinal troughs considerably increases the strength of the vessel in longitudinal direction.
  • transverse partitions 14 are placed with some regularity in longitudinal direction of the vessel, thereby achieving a sub-division into compartments.
  • a watertight partition 15 is also placed in the longitudinal troughs. This avoids the possibility in particular circumstances of the longitudinal troughs completely filling with water.
  • FIG 4 shows a schematic view, partly in cross-section, of a part of the hull of vessel 1.
  • Transverse troughs 9 are shown here which run substantially parallel to each other at some mutual distance in transverse direction of the vessel.
  • Longitudinal troughs 2 are connected in pairs by means of transverse troughs 9.
  • the connection between longitudinal troughs and transverse troughs is preferably also effected by means of known welding techniques.
  • At least a number of the transverse troughs runs endlessly through the hull as according to the preferred embodiment shown in figure 4.
  • Figure 5A finally shows a schematic top view of the connection of two longitudinal troughs by a transverse trough.
  • Figure 5B shows a trough 2 or 9 of the foregoing figures in more detail.
  • a suitable trough consists of sheet material which is rolled into the desired form. Particularly suitable is steel.
  • the steel preferably has quality designation "grade A", which is a common material in the ship-building field. This material has the advantage of being sufficiently light and strong for the stated application.
  • the choice for this steel type has the practical advantage that because of the common use thereof it is usually available.
  • the time involved in the construction, maintenance and repair of the vessel according to the invention is hereby shortened considerably.
  • Trough 2, 9 has three closed sides 16, 17 and 18 and is open on one side, the bottom side.
  • the angle formed by pairs of closed sides is of course greater than 90°.
  • the radius of this angle preferably lies in the range between 20 and 30.
  • the radius is more preferably 25.
  • the trough is welded with the open side onto the relevant wall, for instance surface 4, of hull 3.
  • the trough is provided for this purpose with chamfered edges on sides 16 and 18. This is shown in more detail in figure 5C.
  • the welded seam 19 is here arranged at the position of such a chamfered edge.
  • the troughs are provided where necessary with further chamfered edges.
  • Each of the troughs is in principle formed integrally.
  • stiffening construction according to the invention can be adapted to any type of vessel.
  • the following parameters are among those which must be calculated to size:
