JP5153415B2 - Equipment installation structure in the ship engine room - Google Patents

Description

  The present invention relates to a ship formed in such a manner that, in the engine room of a ship, a main device and its peripheral devices are used as a substitute for a mounting base and a mounting base member in place of the tank installed in the engine room, and the device is installed on the upper part thereof. The present invention relates to a device installation structure in an engine room.

  Main equipment such as fuel purifiers, lubricant purifiers, and bilge separators and peripheral equipment such as control panels and starter panels are installed in the engine room of the ship. The main equipment and peripheral equipment are installed on the hull block on land individually, and after mounting the hull block in the ship, attention is paid to the safety of adjustment of the connecting part of the hull blocks and piping wiring. It is necessary and is carried out as an inboard work with low workability. Here, the main equipment is placed after the hull block is completed.

  In contrast to the above, the common base 8 made of steel as shown in FIG. 2 is used as a base member, and the fuel purifier 3 of the main equipment and the control panel 4 of the peripheral equipment are placed on the common base, After pre-assembling the fuel purifier unit 7 that has been piped and wired, unit outfitting for batch mounting on the hull block is performed. In addition, a unit mounting method for a longitudinal tube has been proposed (see, for example, Patent Document 1).

With the unit outfitting, installation of fuel purifiers and piping wiring work, which has been conventionally performed on board, can be performed on land with high safety and workability. Further, the pre-assembly for placing the fuel purifier or the like on the common base board 8 and piping is independent from the manufacturing process of the hull block. Since pre-assembly can be performed in parallel, the ship construction period can be shortened. Furthermore, since the fuel purifier unit 7 can be mounted on the hull block at a time, the crane occupancy is reduced as compared with mounting on a single item basis, which contributes to shortening the ship construction period.
JP-A-5-193552

  The conventional unit outfitting such as the fuel purifier unit 7 described above was effective in shortening the ship construction period, but when mounting with a crane or the like, the common base plate 8 supporting the load was necessary. In some cases, the weight and steel cost increased, and therefore unit outfitting could not be employed.

  From the above, the object of the present invention is to install equipment that realizes shortening of the ship construction period without increasing ship weight and steel material cost by substituting the common base board 8 with a tank installed in the engine room in the unit outfitting. To provide a structure.

The equipment installation structure in the ship engine room according to the present invention for achieving the above object is a hollow box type in which the upper part is processed into a support part without using a mounting base member for equipment such as a gantry in the engine room. The main equipment and peripheral equipment in the engine room are placed on the upper part with the tank as a base member.

In the equipment installation structure described above, the upper surface of the tank is reinforced by a reinforcing member, or a base part for equipment installation is formed.

  As shown in FIG. 1, the fuel purifier unit 1 reflecting the equipment installation structure of the present invention has a hollow box type sludge tank 2 whose upper surface is processed into a support portion and reinforced, as a base member, and a fuel is disposed above the sludge tank. Peripheral devices such as the cleaner 3, the control panel 4, the temperature control valve controller 5, and the heat exchanger 6 are mounted.

  The fuel purifier unit 1 reflecting the equipment installation structure of the present invention has a sludge tank 2 installed on the lower surface of the engine room deck 9 as shown in FIG. Therefore, the ship construction period can be shortened by the unit outfitting without increasing the ship weight and the steel material cost associated with the use of the common platform 8.

  According to the present invention, it is possible to eliminate the increase in ship weight and steel material cost, which has been a conventional problem, while realizing the shortening of the ship construction period, which is the merit of unit outfitting.

  Hereinafter, the present invention will be specifically described with reference to an embodiment in the fuel purifier unit 1 shown in FIG.

  Since the sludge tank 2 is used as a basic member of the fuel purifier unit 1, a reinforcing member is added as necessary. Pre-processing such as a mounting piece for mounting a device such as a fuel purifier 3 on the sludge tank 2 is performed.

  On the land with high safety and workability, main equipment and peripheral equipment such as fuel purifier 3, control panel 4, temperature control valve controller 5 and heat exchanger 6 are mounted on the top of the sludge tank 2. It is fixed by the method. At the same time, fuel pipes, steam pipes, fresh water pipes, etc. are installed, wiring is performed as much as possible, and combing (expansion prevention walls) is attached to prevent expansion when oil leaks. The pre-assembly of the machine unit 1 is completed. As described above, the pre-assembly of the fuel purifier unit 1 can be performed independently from the hull schedule.

  Since the fuel purifier unit 1 is mounted and fixed to the hull block at once after the pre-assembly is completed, the crane occupation rate is reduced and the ship building period is shortened. In addition, since most of the work related to equipment installation can be performed on land with high safety and workability, after the hull block is mounted on the hull, installation of equipment is completed only by adjusting and joining pipes and the like. To do.

  From the above, by using the fuel purifier unit 1 reflecting the equipment installation structure of the present invention, without increasing the ship weight and the steel material cost seen in the conventional unit outfitting using the common platform 8. The ship construction period can be shortened.

  FIG. 3 is a side view of an embodiment of the bilge separator unit 10, and FIG. 4 is a top view of the bilge separator unit 10.

  Similarly to Example 1, on the land, the bilge separator 12 and the bilge pump 13 are placed on the bilge tank 11 to perform piping. Furthermore, by placing the oil sensor 14, the three-way valve 15 controlled by the oil sensor, and the control panel 16, performing piping and wiring, and further completing the welding of the combing 17 that prevents the oil from flowing out, The pre-assembly of the bilge separator unit 10 is completed. Thereafter, the bilge separator unit 10 is collectively mounted on the hull block, and the block is mounted on the hull.

  3 and 4, A is connected to the waist oil tank installed on the bottom of the ship, B is connected to the drainage port to the outside of the ship, and this pipe A and pipe B are mounted on the hull of the hull block. Connected after completion.

  As described above, the bilge separator and peripheral devices are unitized using the bilge tank, so that most of the work related to the bilge separator can be performed on land. The ship construction period can be shortened without increasing the steel cost.

  Similarly, other main devices in the ship engine room can be unitized.

  FIG. 5 shows an apparatus installation method according to the present invention, taking the fuel purifier unit 1 as an example. The first step 51 is a pre-assembly step of the fuel purifier unit 1 in which the fuel purifier 3 and peripheral devices are placed on the upper part of the sludge tank 2 to perform piping wiring, and work on land with high safety and workability. It has become.

  Two methods are shown from the second step.

  On the other hand, the second step 52 is a step of mounting the fuel purifier unit 1 on the hull block 21. The third step 53 is a step of mounting the hull block 21 on which the fuel purifier unit 1 is mounted on the hull 22.

  The other second step 62 is a step of mounting the hull block 21 on the hull 22. The third step 63 is a step of mounting the fuel cleaner unit 1 in the engine room.
