Definitions

  • the invention relates to a mixed cargo vessel, such as for example roll-on/roll-off ships, hereinafter referred to as ro-ro ships.
  • the oil tank or tanks should of course be protected by water tanks in the manner customary for oil tankers.
  • a completely safe and reliable oil tank is provided without any hatches to any other deck, thus providing an unrestricted cargo-deck above the level of the oil tank or tanks, all piping to and from the oil tank or tanks being kept separated from the other cargo areas of the vessel. This is achieved by passing all piping through an area of the superstructure of the ship completely isolated from the other cargo areas, thus preventing any contact with their contents.
  • the oil tank or tanks may optionally be used for other bulk material transport.
  • the material from which the tank or tanks as well as the piping are made should be inert for all materials inten­ded to be transported in that way, such as for example and preferably stainless steel. This will provide the ship with an even larger versatility with respect to the goods to be transported. If the ship comprises a plurality of oil tanks as described above, and it is intended to use one or more of them for different bulk material, it is required that each tank is provided with its own independent piping if only to prevent contamination with the contents of other tanks. In that way it is possible to adapt the ship to whatever alternative cargo offered for its return journey, avoiding sailing in ballast.
  • any and each oil tank should, in addition to the required piping, be provided with a manhole for access to the relevant tank and whereever required monitoring the tank on possible residues of the previous cargo carried therein.
  • tank or tanks In order to avoid imbalance of the ship while at high sea it is important that the tank or tanks is or are filled for at least 95% preferably 98% or more, to prevent substantial amounts of oil or other bulk material from shifting to one side of the ship.
  • the piping and the manhole of the oil tank are preferably located at one side of the ship. Moreover they may be positioned between the oil tank and the corresponding water tank at that location, or alternatively they may be passed through said water tank, though this latter alternative requires additonal precautions for proper fitting of the piping and the passage from the manhole towards the oil tank where they enter and leave the rele­vant water tank.
  • the solutions therefore are well known and are thus not further described.
  • a ship 1 is provided with a car deck 2 with gang­ways 3 in closed position.
  • oil tanks 4 are positioned behind water tanks 5. All piping (not shown) as required for filling and discharging the oil tank or tanks as well as venting them, pass through the superstructure 6, shown more distinctly in Fig.2.
  • an oil tank 4 is surrounde at both sides and at the bottom by water tanks 5.
  • the car deck 2 together with the joining walls 7 provide an uninterrupted surface, separating the oil tank 4 completely from the car deck (upper deck) 2.
  • All piping required for the oil tank 4 is passed through the water tank 5 at the left hand side of the drawing and from there upwards through the upper structure 6, which is completely separated from the car deck 2 (or any other upper deck as the case may be) by wall 7 at the left hand side of the drawing.
  • a manhole for access to the oil tank is positioned at the top of the water tank and provided with a passageway to the oil tank for the potential user.
  • all piping may be positioned between the water tank and the oil tank, thus avoiding the necessity of making the piping fully water­tight.
  • the areas to be used as oil tanks may also be used for general cargo, the latter as a conse­quence of the piping being restricted to bulk material.
  • the relevant tank or tanks should be cleaned meticulously prior to use for another type of bulk material and similarly all piping should be cleaned.
  • the tanks and all piping should consist of a material inert to all intended bulk material. As such stainless steel is eminently suited.
