Definitions
- the present invention relates to a tanker for carrying a bulk cargo, such as an oil.
- double bottom constructions have the drawback that in case the bottom of a cargo tank is penetrated due to corrosion and/or erosion, oil may leak into the double bottom and generate a hazardous mixture of air and hydrocarbonaceous vapours, in case for instance oil is the cargo. Apart from the potential danger for explosion, there would be the requirement for gas detection and thorough ventilation of the double bottom before entry for routine structural inspections. Moreover, access to a double bottom also causes a problem.
- Object of the present invention is to provide a tanker of such a construction that environmental pollution is avoided or minimized in case of wreck or other marine catastrophe with a minimum increase of cost.
- the present invention therefore relates to a tanker for carrying a bulk cargo
- tanker comprises a hull comprising a bottom and double side walls of which each double side wall comprises an inner wall and an outer wall and defines an inner space closed at its lower end, and at least one centre cargo tank having a top wall, a bottom wall and side walls, wherein the bottom of the hull comprises the bottom wall of the cargo tank(s), the inner walls of the double side walls comprise the side walls of the cargo tank(s), and the double side walls extend below the bottom wall of the cargo tank(s).
- the double side walls extend below the bottom wall of the cargo tank for a distance which is at least equal to B/50 wherein B represents the beam of the tanker. The likelihood that the cargo containment will be breached is then minimized.
- the double side walls extend below the bottom wall of the cargo tank for a distance which is at least equal to B/15, wherein B has the meaning as indicated hereinabove.
- the cargo tank is of such a dimension that the H1/H2 ratio is at most 1 when the tank is filled with cargo, wherein H1 represents the hydrostatic head on the bottom wall of the cargo tank due to the cargo in the tank and H2 represents the hydrostatic head on the bottom wall of the cargo tank due to the outside water.
- H1 represents the hydrostatic head on the bottom wall of the cargo tank due to the cargo in the tank
- H2 represents the hydrostatic head on the bottom wall of the cargo tank due to the outside water.
- the tanker comprises transitions, preferably curved transitions, between the bottom wall of the cargo tank and the inner walls of the double side walls extending below the bottom wall of the cargo tank.
- the hull comprises two or more double side walls whereby each inner space is closed at the front end and at the rear end.
- the inner walls of the double side walls are the side walls of the cargo tank.
- each double side may be arranged either parallel or at an angle to each other.
- each double side wall is arranged parallel with respect to each other.
- the double side walls of the tanker in accordance with the present invention may be arranged vertically or at an angle to the vertical, preferably they are arranged substantially vertical.
- the distance between the inner and outer wall of each double side wall is at most B/5, wherein B represents the beam of the tanker.
- the inner spaces defined by the double side walls may be empty, and after discharging the cargo from the tank(s) the inner spaces may be filled with water to function as balast tanks.
- the double side walls are located along the complete cargo tank.
- the inner spaces defined by the double side walls may be used either for the carriage of cargo or for the carriage of water ballast or may be left void.
- the inner spaces and cargo tank(s) may be subdivided to any required extent, both transversely and longitudinally.
- FIG. 1 a cross-section of a tanker in accordance with the present invention is schematically shown.
- the tanker as depicted in Figure 1 having a beam B comprises a centre cargo tank 1 extending longitudinally for any convenient distance and having a top wall 2 and a bottom wall 3, and double side walls each comprising an inner wall 4 and an outer wall 5 and defining an inner space 6.
