Description

  The present invention can be applied to a fluid such as liquefied natural gas (LNG) or oil between a land and a ship, between a floating island and a ship, or between ships, even if the ship fluctuates due to ocean waves. The present invention relates to a fluid handling apparatus for ship delivery that can be delivered while following.

  For example, when a fluid such as liquefied natural gas (LNG) or oil is unloaded from a tanker on the pier to an on-shore storage tank, or vice versa, the tanker swings in a wave. Even so, a fluid handling apparatus for ship delivery that can safely handle the truck while following it is used.

  For example, when handling (delivering) fluid between a land such as a pier and a ship such as a tanker, not only does the ship constantly oscillate with waves, but the fluid is hot, cold, or flammable. Due to the demand for temperature resistance and fire resistance, delivery with a rubber flexible hose is inferior in safety and operability, so it can follow swinging and has excellent temperature resistance and fire resistance. The above-mentioned fluid handling apparatus for ship delivery is used in which the pipes are connected in a freely rotatable manner.

  This fluid delivery device for ship delivery is a loading arm as shown in, for example, Japanese Patent Publication No. 3-49839, and is generally configured as follows.

  For example, a fluid handling device for ship delivery is provided by being connected to a storage tank provided on one side of a delivery part such as a pier, a wharf or a floating island, and the joint part at the tip of this fluid delivery system for ship delivery is connected to the other part of the delivery part. It is drawn and connected to a joint connecting part (manifold) connected to a storage tank provided on the side ship, and the fluid is handled between them, but this ship delivery fluid handling device (loading arm) is generally connected to the storage tank It is provided in the riser pipe (riser pipe) that is connected to the upper end of the riser pipe via a hollow horizontal swivel joint (horizontal swivel joint) and a hollow vertical swivel joint (vertical swivel joint). An inboard arm is provided on the tip of the inboard arm, and a hollow vertical pivot joint (vertical swivel joint) is attached to the tip of the inboard arm. Via an emergency fluid shut-off device at the tip of the outboard arm and a hollow vertical rotary joint (vertical swivel joint) and a hollow horizontal rotary joint. As a configuration in which a joint portion is provided via a (horizontal swivel joint), for example, while rotating the inboard arm in a vertical direction with respect to the riser pipe, the outboard arm is opened and rotated with respect to the inboard arm. Connect the joint part of the tip part to the joint connection part (manifold) provided on the ship and connect the fluid from the riser pipe through the inboard arm and outboard arm, and the joint part between the joint part and the joint connection part. It is configured so that cargo can be handled on the storage tank of the ship.

  In addition, this loading arm has, for example, an upper sheave for rotating the outboard arm at the tip of the inboard arm, and a lower sheave at the lower end of the inboard arm, and a connecting material such as a wire rope between them. For example, the lower sheave is rotationally driven by a driving device so that the upper sheave is transmitted and driven so that the outboard arm is opened and closed in a direction perpendicular to the inboard arm.

  Also, the lower sheave is provided with a balance weight mounting arm that rotates in conjunction with the outboard arm, and this balance weight mounting arm is provided with a balance weight so that when the outboard arm is opened and closed, the balance weight is also provided. It is configured to be interlocked and rotated for balance.

  In this way, it is equipped with a balance weight mechanism that balances the balance weight by changing the position of the balance weight according to the rotation posture of the outboard arm, and further, the inboard arm and the outboard arm are rotated a predetermined amount each in a predetermined direction. In addition to providing a hydraulic drive device that is dynamically driven, during a cargo handling operation in which the joint portion and the joint connection portion are connected, the hydraulic pressure of each hydraulic drive device is turned off and the circulation switching valve is switched so that a pressure oil circulation conduit is formed. By releasing the drive after the connection and switching to this (to enter the free wheel mode), the arms can freely rotate while maintaining a balance, and the swivel joints cause the ship to oscillate due to ocean waves. However, the load due to this swinging is not applied to the connection part between the joint part and the joint connection part. It is way.

  As described above, the ship handling fluid cargo handling apparatus is operated manually or by operating a drive device (for example, remote control) in a situation where the joint connecting part for connecting the joint part is shaken by a wave at sea and the joint part is connected. ) Are moved closer to the swinging joint connecting part (manifold), aligned (moving finely adjusted), and airtightly connected by a connecting mechanism such as a bolt stop or a hydraulic coupling.

  However, the connecting operation in such a ship delivery fluid cargo handling apparatus is always performed while relatively swinging, and is therefore a very troublesome operation and requires skill. Also, if the waves are high or the wind is strong, this work becomes even more difficult and the work time is considerably spent.

  In bays and harbors with breakwaters, the waves are suppressed and the operation is relatively calm. However, if the waves are still high, or if the ship is unloaded directly from an oil or gas field base or floating island at sea, or FPSO When handling cargo between a floating offshore oil and gas production and storage facility and a ship, there is nothing to block the waves, and there are many situations where the waves are high and work in a large relative swing is forced. This connecting operation is very troublesome and takes a long time.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  Liquefied natural gas (LNG), oil, etc., between shores such as piers and wharves or offshore structures such as oilfields and gas fields, offshore structures such as floating islands, and ships such as tankers and ships (including FPSO) When handling a fluid that requires high temperature resistance and fire resistance, this device (a vessel handling fluid handling device) is provided on one side of this delivery part, for example, the land side, and the tip part (eg, loading) of this equipment is provided. The joint portion 3 of the arm's outboard arm 2) is connected to the joint connecting portion 4 (manifold) provided on the other side, that is, the ship side, and fluid is transferred from the storage tank on the land side to the storage tank on the ship side. In the connecting operation for connecting the joint portion 3 and the joint connecting portion 4, since the ship that has berthed is rocked by waves, the joint connecting portion 4 is It is swung in.

  In particular, when handling cargo between an offshore structure without a breakwater and a ship berthing or between ships, the waves are high and oscillate.

  In such a situation, the joint part 3 is operated closer to the joint connecting part 4 and aligned at the front face, and the flange part between the joint part 3 and the joint connecting part 4 is bolted or connected by a connecting mechanism such as a hydraulic coupling. Will be.

  In the present invention, the inboard arm 1 is horizontally swung or tilted vertically with respect to the rising pipe 10 connected to the storage tank, for example, by manually driving or driving each of the above-described driving devices (which may be operated remotely). While rotating, the joint connecting portion 4 is further pivoted relative to the joint portion 3 provided at the distal end portion of the outboard arm 2 by opening and rotating the outboard arm 2 relative to the inboard arm 1. Move closer to.

  At this time, the joint part 3 and the joint connection part 4 are not brought close to each other and connected as in the past (if the wave is not high and the movement can be controlled smoothly, it may be connected as usual). In the invention, the magnet portion 6 (or the attracting portion) provided in the tip portion of the outboard arm 2 or the joint portion 3 provided in the tip portion of the outboard arm 2 or the attracting portion 5 (or the magnet portion 6) once provided below or around the joint connecting portion 4. 5) is attracted (the magnet portion 6 and the attracting portion 5 may be provided on either side, and both may be regarded as a magnet portion, and one of them may be regarded as an attracting portion. 6 is provided, and the suction portion 5 is provided below the periphery of the joint connecting portion 4 on the other side.

  For example, when the magnet unit 6 is an electromagnet, for example, a weak current is passed during adsorption (just before adsorption) to make the magnet unit 6 a magnet, but the joint unit 3 is moved toward the joint coupling unit 4. First, before connecting the joint portion 3 to the joint connecting portion 4, the magnet portion 6 is moved to the attracting portion 5 and once attracted thereto.

  In the case of a configuration in which each arm is rotated not by hand but by a drive device, the drive device is switched in the same manner as when the normal connection is completed in this attracted state, and each arm is freed as in the cargo handling operation ( Free wheel mode) and swivel of the ship by each swivel joint.

  For example, a sensor may be provided that detects that it has been sucked, so that the drive device can be turned off and automatically switched to the freewheel mode.

The fluid can be handled from the rising pipe 10 to the storage tank of the ship through the inboard arm 1 and the outboard arm 2 and further through the connecting portion between the joint portion 3 and the joint connecting portion 4.

  In addition, the ship handling fluid handling device (loading arm) of this embodiment is provided with an upper sheave 17 for rotating the outboard arm 2 at the tip of the inboard arm 1, and the lower end of the inboard arm 1. Is provided with a lower sheave 18 between which a connecting member 19 such as a wire rope is wound, and the lower sheave 18 is rotationally driven by a hydraulic drive device via a drive sheave or the like so that the upper sheave 17 is transmitted and driven. Thus, the outboard arm 2 is configured to open and close in the vertical direction with respect to the inboard arm 1.

  Also, the lower sheave 18 is provided with a balance weight mounting arm 20 that rotates in conjunction with the outboard arm 2, and the balance weight mounting arm 20 is provided with a balance weight 20A, whereby the outboard arm 2 is opened and closed. When rotating, the balance weight 20A is also configured to rotate in conjunction with the balance.

  In this embodiment, the hydraulic drive device that drives each arm in a predetermined direction is provided as described above, and the movement of the joint unit 3 can be controlled by controlling the operation of the hydraulic drive device. Although the freewheel mode can be followed by the switching operation of the valve or the like, the present invention may be applied to a ship handling fluid handling apparatus that does not have such a drive device and is moved manually.

  In the present embodiment, the present invention can be applied to a loading arm that can be driven to move by such a hydraulic drive device, and can be switched to a free wheel mode after the moving operation is completed and connected, and is provided with a balance weight mechanism.

In particular, the heights of the joint portion 3 and the joint connecting portion 4 can be matched so that the vertical alignment is not necessary.

  As described above, the suction unit 5 and the magnet unit 6 may be designed so that the alignment is completed, or a positioning mechanism or the like may be separately provided in the suction unit 5.
