Definitions

  • the present invention relates to oil tankers in a broad sense, namely pure oil tankers and convertible oil tankers capable of loading solid cargo such as ore or coal as well. More particularly it relates to their piping structures for cargo oil and other pipes.
  • Fig. 8(a) shows one known oil tanker, in which cargo oil pumps 17 are provided in a pump room 16 in front of an engine room 18.
  • Cargo oil suction pipes 57 interconnect the cargo pump 17 and each of cargo tanks; cargo oil delivery pipes 50 interconnect the pump 17 and shore connections 48 provided amidship on an upper deck.
  • cargo oil suction pipes 57 are passed as low as possible in the cargo tanks to improve suction efficiency.
  • cargo oil delivery pipes 50 are raised from the pump room up to an upper deck 30 and extends on the upper deck to the midship portion of the hull.
  • the cargo oil delivery pipes 50 running on the upper deck may be exposed to spray from sea water waves, and susceptible to corrosive damage, resulting in much maintenance costs. Further, since cargo oil delivery pipes are normally large in diameter, the existence of the pipes on upper deck may obstruct the worker's traffic particularly in transverse direction of the ship.
  • the cargo oil delivery pipes 50 should be passed within cargo oil tanks, at midship raised above the upper deck, and then connected to the shore connection 48 as shown in Fig. 8(b) .
  • Such pipe arrangement can make the upper deck free of the cargo oil delivery pipe 50, thus eliminating pipe corrosion by sea spray and an obstruction to worker's traffic on the upper deck.
  • pipes which may obstruct traffic on an upper deck are not only cargo oil delivery pipes but also a fuel oil loading pipe, a cargo oil stripper pipe, a fire main pipe, a tank cleaning pipe, an electric wire duct pipe, and so on.
  • an inert gas system in order to prevent an explosion accident, recent large tankers are provided with an inert gas system.
  • the system has an inert gas generator disposed aft portion of the hull, from which an inert gas main pipe extends forward on upper deck, resulting in obstruction to traffic on the upper deck.
  • the object of the present invention is to solve such problems in pure or convertible oil tankers.
  • a taker having a piping passage longitudinally extending within a hull of the tanker.
  • a cargo delivery pipe is run through in said passage to interconnect a pump room at an aft portion of the hull and a shore- connection provided amidship on the upper deck.
  • the passage is surrounded by watertight structures and particularly an inside top portion thereof is formed by the upper deck.
  • the piping passage under the upper deck for housing cargo delivery pipes, it is possible to minimize the possibility of the oil flowing down into the sea in the event of oil leakage in the cargo delivery pipe.
  • the upper deck can be kept free of the cargo oil delivery pipes, it is easy for workers or carts to move on the upper deck. Further, the cargo oil delivery pipes within the piping passage are not exposed to spray from sea water waves, thus preventing corrosive damage and maintenance costs reduced.
  • Such pipes may include an inert gas pipe, a tank cleaning pipe, a fire main pipe, an electric wire pipe, a cargo oil stripper pipe, and a fuel oil loading pipe.
  • This arrangement may solve the problems of on-deck traffic, deck cleaning, and corrosion of the pipes.
  • the pipes such as the inert gas pipe, the tank cleaning pipe, and the fire main pipe are run near to a bow part, therefore, the piping passage housing these pipes have to also extend near to the bow.
  • the piping passage is arranged in contact with longitudinal bulkheads for dividing the inside of the hull into the oil tanks in rows or in contact with a side ballast tank.
  • hull structure members can serve as a part of walls of the piping passage. Thus the amount of structural material and building cost can be saved.
  • the piping passage is preferably fitted with some doorways leading to the upper deck.
  • the inside of the passage have enough space for worker to pass through it.
  • the piping passage is equippeded with a ventilator, a gas detector, a sprinkler system, and the like to provide for gas explosion or fire.
  • a hull space of an ore/oil carrier is divided by transverse bulkheads 10, into a bow portion 12, a cargo space 14, a pump room 16, an engine room 18, and a stem portion 20.
  • An accommodation space 22 is located on the engine room 18 and a wheelhouse 24 is thereon.
  • the cargo space 14 has a double hull structure at both of hull bottom and hull sides, and insides of them form ballast tanks 26, 28.
  • the cargo space surrounded by these double hull structures and an upper deck 30 is divided by two longitudinal bulkheads 32 into central cargo oil tanks (or ore hold) 34 and wing cargo oil tanks 36.
  • cargo hatch 38 is provided on the upper deck 30, and the hatch is equipped with an oil-tight hatch cover 40.
  • Water-tight piping passages 42 with almost rectangular cross sections are extending longitudinally within an upper portion of the central cargo oil tank 34.
  • the passage is located between the longitudinal bulkheads 32 and cargo hatches 38, the upper side of the passage 42 is defined by the upper deck 30; the outer and inner sides thereof are defined by a longitudinal bulkhead 32 and a hatch side girder 46, respectively.
  • Hull structure members 32, 46 serve as side walls of the piping passage so that the passage can be built at reduced costs.
  • Some pipes 54 including a fuel oil loading pipe and a cargo oil stripper pipe are passing through the starboard passage 42 and connected to the shore connection 48.
  • Inert gas supply pipe 58 which have big diameter like the cargo oil delivery pipe 50, are passed through the port passage to the bow. As shown in Fig. 4 , branch pipes 60 branching off from the inert gas pipe 58 run above the upper deck and reach the respective cargo oil tanks 34, 36.
  • some pipes 62 including a tank cleaning pipe, a fire main pipe and an electric wire pipe pass through the port passage and extend to the bow portion as shown in Fig. 3 and Fig. 4 ,
  • access hatches 68 having watertight covers are provided. Passages 42 are preferably sufficiently large to permit workers to pass through.
  • Passages 42 are preferably equipped with ventilators, gas detectors, fire extinguisher (for example, of a carbon dioxide type), and the like to provide for gas explosion.
  • a numerical reference 57 indicates cargo oil suction pipes, which are located at a bottom portion of the wing cargo tanks 36 to extend toward the pump room 16.
  • passages 42 are sandwiched between the longitudinal bulkheads and the cargo hatch.
  • Fig. 5 shows another passage arrangement, where the passages are located in contact with the side ballast tanks 28, and the outer side of the passage 42 is defined by an inner wall 29 of the side ballast tank 28. Piping disposition in the passage 42 are the same as those in the case of Fig. 3 .
  • Fig. 6 is the case for a pure oil tanker. Since it has no cargo hatches, a single passage 42 is provided along a center line of a hull as shown with chain lines in the drawing, in which a cargo delivery pipe, an inert gas pipe, and other pipes are accommodated. Instead of centerline passage, two passages 42 may be located at both sides symmetrically and in contact with side ballast tanks as shown with solid lines in the same drawing.
  • Fig. 7 shows an embodiment of an OBO, that is, oil/bulk/ore carrier.
  • Piping passages 42 are formed between side ballast tanks 28 and cargo hatches 38.
  • the cargo hatch is so wide that hatch side space on upper deck is very narrow. So it is of a great advantage to provide piping passages under the upper deck.
