Description

Method for repairing electrolysis type ballast water treatment system {Method for reparing electrolysis type BWTS}

The present invention relates to a method for repairing an electrolysis type ballast water treatment device.

The installation of eco-friendly equipment and equipment on ships is increasing. In the International Maritime Organization (IMO), regulations on items that are the main culprits of air and water pollution are being strengthened. Therefore, ship owners are obliged to install eco-friendly equipment on their ships.

As a result, the burden of work for seafarers to deal with a large number of eco-friendly equipment is increasing. While sailors have the ability to solve problems of ship operation and each facility on board to some extent, the equipment of eco-friendly equipment has not been used in the past, and most of them are recently installed and installed and are not familiar to sailors. As a result, crews who had to handle the equipment were forced to drive themselves without adequate training and were faced with the reality.

In particular, when a failure occurs in the ballast water treatment system, which has recently been mandatory to be installed, it is very difficult for sailors to repair the failure on their own without external help.

According to the present invention, there is provided a method for repairing an electrolysis type ballast water treatment device.

1 is a flowchart illustrating a repair method of an electrolysis type ballast water treatment apparatus according to an embodiment of the present invention.

Existing manuals (including printed materials and electronic files) for repairing ballast water treatment devices on ships consist of text and drawings, and image files of drawings and products cannot be rotated 360 degrees, and can only be viewed in one direction. For this reason, there is a difficulty because it is not intuitive when sailors want to operate, maintain, and repair equipment using the existing manual.

The ballast water treatment system is a complex system composed of several products. As a result, crew members are experiencing difficulties in operating and operating the ballast water treatment system. Ships are not easy to access during operation and movement, and the location and time of arrival and departure can be flexibly changed.

On the other hand, a supplier that manufactures and sells ballast water treatment equipment requires many engineers to continue dispatching engineers whenever a problem occurs, and also has a problem in that manpower operation costs increase accordingly.

Analysis of the A/S measures after the engineer dispatched shows that there are more malfunctions due to the crew's inexperienced operation and lack of experience in equipment operation, rather than the proportion of material costs due to replacement of parts, so the proportion of labor costs and expenses is high. These costs are a burden to the manufacturers and sellers during the free A/S period, and act as a burden to the shipowner during the paid A/S period.

The present invention is to solve the above problem, and provides a countermeasure against a failure through communication between a ship and a failure handling center installed on the ground.

The present invention will be described below with reference to the drawings.

1 is a flowchart illustrating a repair method of an electrolysis type ballast water treatment apparatus according to an embodiment of the present invention.

First, in the vessel in operation, the failure details of the ballast water treatment device installed in the vessel are wirelessly transmitted (S100).

The ballast water treatment device is an electrolysis type. The electrolysis type ballast water treatment device produces sterilized water by electrolyzing influent water. Part or all of the influent is electrolyzed to produce sterilized water, and then mixed with the rest of the influent (when part of the influent is electrolyzed) and supplied to the ballast tank. The ballast water treatment device includes a concentration measuring unit for measuring the concentration of sterilizing components in the sterilizing water and a separate brine tank. The configuration of the electrolysis type ballast water treatment device may be variously changed.

In the present invention, 'influent water' may include seawater, fresh water and/or brackish water depending on the location of the vessel.

The failure history may be a failure history for equipment or an alarm message from a control panel.

Next, the failure details are input (S200) from the failure handling center installed on the ground.

The wireless transmission method between the ship and the troubleshooting center may be various, such as using a communication satellite, and some communication within the ship may be wired.

The failure handling center selects a countermeasure corresponding to the failure details (S300).

In selecting the countermeasure, the first database and the second database can be used.

In the first database, components, failure types, causes, and countermeasures are provided for each facility as shown in Table 1, and in the second database, corresponding parts, causes, and countermeasures are provided for each alarm message as shown in Table 2.

The failure handling center analyzes the failure history and derives countermeasures suitable for the failure history from the first database and the second database. The derivation of suitable countermeasures can be carried out using computers, in particular artificial intelligence.

<Table 1>

<Table 2>

If there are a plurality of countermeasures, priority is given (S400).

Prioritization is performed based on the operation information.

Operation information includes the salinity of the influent water in the area where the vessel operates, the temperature of the influent water in the area in which the vessel operates, the age of the vessel, the age of the ballast water treatment equipment, the operation history of the ballast water treatment equipment, and existing failures and repairs of the ballast water treatment equipment. It may include at least one of the details.

These operation information may be received by requesting the vessel from the trouble-shooting center, or some operation information may already be grasped by the trouble-shooting center. Alternatively, when a ship reports a breakdown, some operation information may be automatically transmitted to the trouble handling center.

Some of the operation information can be grasped by the troubleshooting center from the location of the vessel.

An example of assigning priority is as follows.

Example 1

As for the alarm that the breakdown is low in the electrical conductivity value in the electrolyzer, (1) compare the conductivity display value with the HMI value (2) check the cable and (3) There are three possible countermeasures for connecting the brine tank to the water intake line.

The troubleshooting center identifies the salinity of the influent water in the area where the ship operates from the location information of the ship. If the salinity of the influent water is lower than the standard value due to the reason that the area where the vessel operates is in the area adjacent to the river, the measures taken from among a plurality of measures are prioritized.

Example 2

For the alarm that the water intake temperature is lower than the reference value (set value) in the breakdown, as in the countermeasures for the TS301 alarm message in Table 1, (1) measure the water intake temperature with a portable temperature sensor and compare (2) the operation of the heating device Two measures are possible.

The trouble handling center grasps the temperature of the area in which the ship operates or the temperature of the influent water from the location information of the ship. If the temperature of the influent in the area where the vessel operates is lower than the standard value, (2) The countermeasures to operate the heat exchanger that heats the influent are prioritized.

The above countermeasures selection and prioritization can be performed through a computer or artificial intelligence, and artificial intelligence can improve the accuracy of countermeasures selection and prioritization through learning.

Artificial intelligence can learn the breakdown, repair history, and results of other ships, and can predict the occurrence of failures through normal data and failure data collected before the failure.

Thereafter, the selected countermeasures are transmitted to the ship (S500), and repair is performed.

The repair process can be carried out using augmented reality, and smart glasses can be used.

The smart glasses worn by the sailors are connected to the in-ship wired and wireless communication and to the outboard land base station (failure handling center). It shares the same screen with the experts of the land base station, that is, the situation of the equipment in the ship, which was captured in real time through the smart glasses worn by the sailor. Through the shared screen, the experts of the land base station can grasp the situation inside the ship without having to board the ship. Sailors on board and experts at land base stations transmit and receive mutual communication through voice and text. In addition, it includes a function to transmit and receive each other by marking the part that needs to be inspected on the captured screen and transmitting it. The access network also includes a function of simultaneously accessing several people.

It includes the functions of communicating with the crew on board and the experts of the onshore base station control center, as well as sending and receiving information and documents.

There are cases where sailors disassemble and assemble parts for repair and maintenance. At this time, an augmented reality screen can be provided so that the crew can disassemble and assemble the actual parts while watching the augmented reality.

In addition, in order to overcome the difficulty in finding information and materials provided because the system is complex and consists of many units and parts, QR codes can be attached to each device from the time of product shipment.

The above first embodiment can be variously changed, which will be described with reference to the second embodiment and the third embodiment.

In the second embodiment, based on (1) the existing breakdown and repair history of the ballast water treatment device and (2) the current failure of the ballast water treatment device and the selected countermeasures, failure types and countermeasures that are highly likely to occur in the future are suggested.

The second embodiment will be described by exemplifying a failure in which the electrolytic cell efficiency is lowered.

When influent water enters the electrolyzer, an electric current is applied to perform electrolysis, thereby generating sterilizing water. However, the more frequent use and accumulated use time in a harsh environment increase, the lower the efficiency of the electrolyzer, and a higher current value is required to create a target concentration of sterilizing water.

As a countermeasure against the degradation of the electrolytic cell efficiency, there is electrode cleaning. Cleaning can be operated by referring to the manual of the CIP (Clean In Place) unit provided by the manufacturer. The cleaning principle of the CIP unit is to chemically remove the scale attached to the electrode using citric acid.

If it is expected that it will be difficult to improve the efficiency of the electrolytic cell only by removing the scale attached to the electrode based on the existing cleaning history and the current cleaning history, it is possible to predict and suggest the time of failure due to scale formation in the future and the need for electrode replacement.

In the third embodiment, (1) the age of the ballast water treatment device, (2) the operation history of the ballast water treatment device, (3) the previous breakdown and repair history of the ballast water treatment device, and (4) the current breakdown of the ballast water treatment device Based on the selected measures and measures, measures for future periodic inspections are suggested.

The third embodiment will be described by taking the TRO sensor as an example.

The TRO (total residual oxidant, total residual oxide) sensor is a sensor used in both the ballasting and deballasting processes in the ballast water treatment system, and measures the total residual oxide concentration of the sterilizing water using reagents, which are consumables. Consumables consist of powder, indicator, and buffer, and have an expiration date.

Table 3 shows the alarm messages, causes and countermeasures for the TRO sensor.

<Table 3>

The failure of the TRO sensor may occur more frequently as the age of the ballast water treatment device increases and the operation time of the ballast water treatment device increases. In particular, buffer lines and check valves may deteriorate due to prolonged use, making repair difficult.

By judging on the basis of the model year, existing failure history and actions, current failure history and actions, etc., replacement of the buffer line and check valve can be suggested as a measure for future periodic inspections.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and it is common in the technical field to which the present invention pertains that various substitutions, modifications and changes are possible without departing from the technical spirit of the present invention. It will be clear to those who have the knowledge of
