Description

Barge for transferring marine structure and balancing method

The present invention relates to barges and methods for maintaining equilibrium for transporting offshore structures.

A barge is a ship that generally has a flat top surface and carries offshore structures (eg, cargo, ship blocks, offshore installations, etc.) to a designated location.

Barges are equipped with ballast tanks (ie, ballast tanks) to maintain stability and promote propulsion efficiency. The ballast tank is intended to reduce the fluctuation of the ship's center of gravity by loading and unloading offshore structures and to ensure safe navigation.

When the offshore structure is manufactured at the shipyard and transported to a predetermined position, the barge is moved near the quay wall, and a load out rail for moving the offshore structure to the top of the barge is connected to the quay wall and the top of the barge. The offshore structure is then moved over the barge using a load out rail.

In the process of moving the offshore structure above the barge, the weight of the offshore structure is partially moved to the barge, and a step occurs in the barge and the quay wall, which may cause a large accident.

In order to prevent such an accident, a ballasting operation is performed to control the level of seawater stored in the ballast tank to maintain a constant draft of the barge.

In the conventional ballasting operation, a specific worker checks the gap between the inner wall and the barge by using a tide prediction table and a precision meter on the inner wall, and then checks the information of the ballast tank of the barge. It is carried out in such a way that it is transmitted to another worker and requires the operation of the ballast pump.

However, the conventional ballasting operation has a limitation in that it cannot precisely respond to changes in the marine environment in real time.

1 and 2, the balancing system of the barge 200 is collectively referred to as a plurality of zone ballast units 110-1, 110-2,. The controller 120 and the storage unit 130 may be included.

The barge 200 may be divided into a plurality of ballast zones to maintain balance, and the zone ballast unit 110 may be provided to correspond to each ballast zone, respectively.

Therefore, the barge 200 formed integrally has a feature that the balance is maintained as a whole by the ballast treatment of the zone ballast units 110 that perform the balance maintaining process based on each ballast zone.

The zone ballast unit 110 provided in each zone may include a ballast unit 112 and a distance detector 114.

The ballast portion 112 adjusts the water level of the seawater stored in the ballast tank provided in the ballast zone allocated to the zone ballast unit 110.

For example, the ballast part 112 is operated to correspond to the output signal of the ballast tank, the pump driver controlled by the controller 120, the pump driver, and stores the seawater and injects the seawater into the ballast tank or the ballast tank It may include a ballast pump for adjusting the water level inside the ballast tank by flowing the seawater inside.

The distance detector 114 may be implemented, for example, including a distance sensor. The distance detector 114 is mounted at a predetermined position of the assigned ballast zone to sense a distance to the sea level (for example, a height spaced apart from the sea level), and sense information corresponding to the sensed distance (eg, Information about the digitized distance value) may be generated and provided to the controller 120.

When the distance sensing unit 114 of each zone ballast unit 110 provides detection information generated by the controller 120, the zone ballast unit 110 may include identification information about the corresponding zone ballast unit 110.

The controller 120 may store and manage the sensing information and the identification information provided from the distance sensing unit 114 provided in each ballast area in the storage unit 130.

The controller 120 may set an individual reference value corresponding to each ballast zone by using the distance value included in the sensing information provided from each distance detector 114 at the start of the load-out operation for the offshore structure 210. have. The received sensing information and information on the set individual reference values may be stored and managed in the storage 130.

At the start of the load-out operation, since the inner wall and the upper surface of the barge are in a horizontal state, if the sensing information provided from the distance detecting unit 114 for each ballast section is maintained to correspond to an individual reference value, the controller 120 It can be judged that the top surface of the quay and the barge remain horizontal.

However, if the sensing information received from the distance detector 114 corresponding to any ballast zone during the load-out operation of the offshore structure 210 has a difference that is greater than the error range with respect to an individual reference value, the controller 120 It can be recognized that the quay and step are formed in the ballast zone. In this case, the controller 120 controls the operation of the ballast unit 112 provided in the ballast zone so that the sensing information in the distance detection unit 114 of the corresponding ballast zone corresponds to a predetermined reference value.

The sensing information may be set to be sensed at each point in time by the distance sensing unit 114 and provided to the controller 120, or may be set to be provided in units of a predetermined period (for example, 1 second).

In addition, although the comparison distance value compared with the individual reference value may use the sensing information itself provided by the distance detecting unit 114, the sensing information provided by the controller 120 for a predetermined period (for example, 30 seconds) may be used. It may be generated by calculation (for example, average value).

Hereinafter, the process of maintaining the balance of the barge will be described in detail with reference to FIGS. 2 and 3.

As illustrated in FIG. 2A, in order to move the offshore structure 210 on top of the barge 200, the barge 200 is moved to be close to the quay wall and the load out rail 220 is barge. 200 is installed to connect the top and the top of the inner wall.

As illustrated, the barge 200 is partitioned into a plurality of ballast zones to maintain equilibrium, and a zone ballast unit 110 including a ballast portion 112 and a distance sensing unit 114 corresponding to each ballast zone is provided. Each is provided. Each zone ballast unit 110 communicates with the controller 120 to control the level of seawater stored in the ballast tank by the control of the controller 120.

Referring to FIG. 3, at the reference point before moving the marine structure 210 to be transported to the upper part of the barge 200, the controller 120 senses the distance from the distance sensing unit 114 of each zone ballast unit 110. The sensing information corresponding to the distance to the sea level is provided, and an individual reference value for each ballast zone is set using the provided sensing information (step 310).

For example, the reference time point may be previously designated as a time point at which the barge 200 stops moving due to proximity to a quay wall, and a time point when an administrator inputs a setting command of an individual reference value.

By providing the sensing information and the identification information to the controller 120 by the distance detecting unit 114 of each zone ballast unit 110, the controller 120 may recognize which ballast zone each individual reference value is set for. .

As illustrated in FIG. 2 (b), when the offshore structure 210 to be transported begins to move to the top of the barge 200, the weight of the offshore structure 210 is partially moved to the barge 200 so that the barge ( 200) and a step occurs in the inner wall.

For example, when the weight of the offshore structure 210 is applied to the stern portion of the barge 200, the stern portion (for example, the ballast area provided with the distance sensing portion S1 and the ballast portion B1) is relatively lower than the bow portion. The distance sensing unit 114 provided at the stern portion to sit down will sense a relatively short distance from the sea surface. Thus, in order to maintain a horizontal level with the quay wall, the ballast portion 112 provided at the stern portion will be controlled to store a relatively small amount of seawater in the ballast tank.

This process may be performed individually in each ballast zone by the control of the controller 120 until the offshore structure 210 is moved to a designated position above the barge 200, as illustrated in FIG. 2 (c). will be.

Referring again to FIG. 3, while the offshore structure 210 to be transported is moved to the top of the barge 200, the controller 120 detects the distance detector 114 of each zone ballast unit 110 disposed in each ballast zone. Receive sensing information detected in operation 320. For example, the sensing information may be received in real time or may be preset to be received at a predetermined period.

In operation 330, the controller 120 compares the received sensing information for each ballast zone with a preset individual reference value and determines whether there is a ballast zone having a difference greater than or equal to an error range for the individual reference value. In this case, the comparison distance value compared with the individual reference value may be information of the sensing information itself provided by the distance detecting unit 114, but a result value in which the sensing information provided for a predetermined period (for example, 30 seconds) is calculated. (For example, an average value).

If there are no ballast zones that differ by more than the error range relative to the individual reference values, then the barge remains level with the quay wall and proceeds to step 320 again.

However, if there is a ballast zone having a difference greater than or equal to the error range compared to the individual reference value, the controller 120 determines that the ballast portion of the ballast zone (eg, the sensing information provided in the ballast zone corresponds to the individual reference value set for the ballast zone). The operation of 112 is controlled (step 340).

4 is a view schematically showing the configuration of a barge balancing system according to another embodiment of the present invention.

Referring to FIG. 4, the balancing system of the barge 200 includes a plurality of zone ballast units 410-1, 410-2,. It may include a central controller 420.

As described above, the barge 200 is divided into a plurality of ballast zones to maintain balance, and each ballast zone is provided with a zone ballast unit 410 individually.

The zone ballast unit 410 may include a ballast portion 412, a height detector 414, a unit controller 416, and a unit reservoir 418.

The ballast portion 412 adjusts the level of seawater stored in the ballast tank provided in the ballast zone allocated to the zone ballast unit 410, and may include, for example, a ballast tank, a pump driver, and a ballast pump.

The height detector 414 may be implemented, for example, in the form of a GPS receiver. The height detector 414 calculates a height value from the calculated three-dimensional coordinate value and generates corresponding sensing information and provides it to the unit controller 416. The height detector 414 is mounted at a predetermined position corresponding to the ballast zone, and calculates a height value of the mounted position.

The unit controller 416 may store and manage the sensing information provided by the height detector 414 in the unit storage 418.

When the operation start command is received from the central controller 420, the unit controller 416 sets a reference height value by using the sensing information provided from the height sensor 414 at a predetermined reference time point, and then the load out operation is performed. During the process, the operation of the ballast unit 412 is controlled by comparing the sensing information provided from the height detector 414 with a preset reference height value.

Here, the reference time point may be, for example, a time when the barge 200 stops moving due to proximity to the quay wall, a time when an administrator inputs a setting command of an individual reference value, and a time when an equilibrium operation is instructed by the central controller 420. Can be specified.

Since the top surface of the quay and barge is horizontal at the start of the load-out operation, if the height value of the height sensing unit 414 for each ballast zone is maintained as a separate reference value, the top surface of the quay and the barge It is kept horizontal.

However, if the detection information provided from the height detection unit 414 has a difference greater than or equal to the error range with respect to the reference height value during the load-out operation of the offshore structure 210, since the corresponding ballast zone is relatively low or high The unit controller 416 will control the operation of the ballast portion 412 such that the height value of the ballast zone corresponds to the reference height value.

Compared to the balance maintaining system described above with reference to FIGS. 1 to 3, the balance maintaining system illustrated in FIG. 4 includes a zone ballast unit 410 including a unit controller 416 for each ballast zone, and a central controller ( When the operation start command is input to the unit controller 416 of each ballast zone in 420, the ballast zone has a difference in the type of distributed control that senses the change in the height value for each ballast zone and performs the ballast operation.

In addition, the balance maintaining system illustrated in FIG. 4 makes it possible to maintain the balance of the barge 200 even in a sea wave situation because the height sensing unit 414, for example, a GPS receiver, uses an absolute height value. There is an advantage.

The height sensing unit 414 of FIG. 4 may be replaced by the distance sensing unit 114 of the balance maintaining system described above with reference to FIG. 1, and the like. Naturally, the sensing unit 414 may be replaced.

5 is a flow chart showing a method for maintaining the balance of the barge according to another embodiment of the present invention.

Referring to FIG. 5, in step 510, the central controller 420 instructs the unit controller 416 of the zone ballast unit 410 provided in each of the plurality of ballast zones included in the barge 200 to perform a balancing operation. do.

Thereafter, the zone ballast unit 410 disposed in each ballast zone performs an equilibrium operation for the ballast zone itself.

For example, an equilibrium maintaining operation performed in the first zone ballast unit 410-1 will be described below.

In operation 520, the unit controller 416-1 of the first zone ballast unit 410-1 that is requested to instruct an equilibrium operation for the designated ballast zone from the central controller 420 is the height sensing unit 414-1. The sensing information corresponding to the height value calculated from the above is provided, and the height value of the received sensing information is set as a reference height value for the corresponding ballast zone. Information about the reference height value may be stored and managed in the unit storage 418-1.

In operation 530, the unit controller 416-1 receives the sensing information from the height sensor 414-1. The sensing information may be calculated and provided by the height sensing unit 414-1 at each time point, or may be provided in units of a predetermined cycle (for example, in units of 1 second).

In operation 540, the unit controller 416-1 determines whether the height value of the sensing information provided from the height sensing unit 414-1 has a difference greater than or equal to a reference height value and a predetermined error range. Here, the unit controller 416-1 may compare the height value of the received sensing information with a reference height value, but the result value calculated using the sensing information provided for a predetermined period (for example, 30 seconds) ( For example, an average value of height values) may be used.

If there is a difference between the reference height value and the error range, the barge 200 is recognized as being horizontal with the quay wall, and the flow proceeds to step 530 again.

However, if there is a difference exceeding the reference height value and the error range, the unit controller 416-1 may determine that the height value measured in the ballast zone corresponds to the preset reference height value. The operation is controlled (step 550).

As described above, the barge and the method of maintaining the balance according to the embodiments of the present invention is carried out by the precise ballasting operation in response to the real-time change of the marine environment, the marine structure 210 to be transported is the top of the barge 220 in the quay wall There is an advantage to be able to move safely.

Since the balance maintenance operation is performed in units of a ballast zone in which the barges 200 are divided into a plurality of parts, more precise balance maintenance can be performed, and the size of the ballast tanks deflected in each ballast zone can be relatively reduced. .

Although the above has been described with reference to embodiments of the present invention, those skilled in the art may variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. And can be changed.
