Description
- 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 whichcargo oil pumps 17 are provided in apump room 16 in front of anengine room 18. Cargooil suction pipes 57 interconnect thecargo pump 17 and each of cargo tanks; cargooil delivery pipes 50 interconnect thepump 17 andshore connections 48 provided amidship on an upper deck. In cargo oil unloading, cargo oil in the respective oil tanks is sucked through the cargooil suction pipe 57 into thecargo pump 17, then sent through the cargooil delivery pipe 50 to theshore connection 48, and is delivered to a reception facility on shore. Cargooil suction pipes 57 are passed as low as possible in the cargo tanks to improve suction efficiency, However, cargooil delivery pipes 50 are raised from the pump room up to anupper deck 30 and extends on the upper deck to the midship portion of the hull. - In the above mentioned piping arrangement, 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.
- In
Patent Documents oil delivery pipes 50 should be passed within cargo oil tanks, at midship raised above the upper deck, and then connected to theshore connection 48 as shown inFIG. 8( b). Such pipe arrangement can make the upper deck free of the cargooil delivery pipe 50, thus eliminating pipe corrosion by sea spray and an obstruction to worker's traffic on the upper deck. - However, in the conventional oil tankers, 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. Further, 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.
- Particularly in convertible oil tankers capable of loading ore and bulk as well, cargo hatches on the upper deck will make the traffic problems more difficult. In addition, during unloading ore or coal, part of it is may spilled on the deck, therefore, on-deck piping requires protective covers. However, spilled ore or coal is apt to collect under the protective cover, thus requiring troublesome work for deck cleaning.
- Accordingly, only by passing the cargo oil delivery pipes within cargo oil tanks it is difficult to overcome the problems of on-deck traffic, deck cleaning, corrosion and deterioration of on-deck pipes.
- Patent Document 1: Japanese Utility Application Laid-open No. Sho 55-107498
Patent Document 2: Japanese Patent Application Laid-open No. Hei 08-295288 - The object of the present invention is to solve such problems in pure or convertible oil tankers.
- According to the present invention there is provided 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.
- By providing 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. In addition 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.
- Not only the cargo oil delivery pipes but also almost all of pipes running longitudinally along on the upper deck in the conventional tanker can be passed through the piping passage. 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.
- Preferably 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, In this arrangement, 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. And also, it is preferable that the piping passage is equipped with a ventilator, a gas detector, a sprinkler system, and the like to provide for gas explosion or fire.

Just above each of centralcargo oil tanks 34,cargo hatch 38 is provided on theupper 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 centralcargo oil tank 34. The passage is located between thelongitudinal bulkheads 32 andcargo hatches 38, the upper side of thepassage 42 is defined by theupper deck 30; the outer and inner sides thereof are defined by alongitudinal bulkhead 32 and ahatch side girder 46, respectively. Hullstructure members - In prior art oil tankers, many pipes run longitudinally on upper deck, however, most of such pipes can be housed in the
passages 42 formed under the upper deck. As shown inFIG. 2 , two piping passages extend forward from thepump room 16, but are different in length; the starboard side passage extends up to the midship, while the port one up to the bow. - To interconnect the
pump room 16 andshore connections 48 at a midship there are provided a total of threecargo delivery pipes 50, two of which extend in the starboard side passage, and the remaining one extends through the port side passage as shown inFIG. 3 . Theshore connections 48 at the starboard and port sides are interconnected withcrossover pipes 52, and thecargo delivery pipes 50 extending in passages are drawn out up to the upper deck at midship and connected to thecrossover pipes 52. - Some
pipes 54 including a fuel oil loading pipe and a cargo oil stripper pipe are passing through thestarboard passage 42 and connected to theshore connection 48. - When cargo tanks become negative pressure while unloading of cargo or at sea, cargo tanks are supplied with inert gas obtained by treating boiler's exhaust gas so as to reduce the possibility of cargo tank's explosion. Inert
gas supply pipe 58, which have big diameter like the cargooil delivery pipe 50, are passed through the port passage to the bow. As shown inFIG. 4 ,branch pipes 60 branching off from theinert gas pipe 58 run above the upper deck and reach the respectivecargo oil tanks - In addition to the cargo
oil delivery pipe 50 and theinert gas pipe 58, somepipes 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 inFIG. 3 andFIG. 4 , - In order to access to the
piping passage 42 from theupper deck 30 for valve operations and a maintenance of piping, 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 thewing cargo tanks 36 to extend toward thepump room 16. - In the above-described embodiment,
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 theside ballast tanks 28, and the outer side of thepassage 42 is defined by aninner wall 29 of theside ballast tank 28. Piping disposition in thepassage 42 are the same as those in the case ofFIG. 3 . -
FIG. 6 is the case for a pure oil tanker. Since it has no cargo hatches, asingle 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, twopassages 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. Pipingpassages 42 are formed betweenside ballast tanks 28 and cargo hatches 38.
