What are the characteristics of ship fog?

(1) Poor visibility and restrictions on sight;

(2) Due to poor visibility, it is impossible to find the surrounding boats at a sufficient distance, and quickly judge that his ship dynamics and the avoidance operations taken by his ship can only rely on AIS, radar observation and labeling, and it is difficult to avoid ships;

(3) Limited by sight, you cannot find nearby objects and airmarks in time, which causes greater difficulties in positioning and navigation;

(4) After the sailing speed in the fog, the impact of romance on the ship increases, which has greatly affected the accuracy of the calculation speed and the accuracy of the voyage. Sailing safety.

Judgment in time according to the visibility

1

When the distance is less than 5 nautical miles, it is considered that the visibility is not good, and the car should be prepared immediately to use the safety speed that is suitable for the environment, conditions and the characteristics of the ship at that time. Turn on the radar and use it correctly, quickly measure the position of the ship, record the reader readings, open the window to strengthen the lookings, and turn on the navigation light.

2

When the visual distance is less than 2 nautical miles, it is believed that the visibility is seriously poor. The captain should be reported immediately, at the same time slow down, according to the flute, the automatic rudder is stopped, the hand rudder is turned on, and the high -frequency wireless phone is turned on and used it correctly. Commanded on the driver's desk. The high -frequency wireless telephone is used in Wushang, which should be kept listening on Channel 16, and regularly broadcast the ship's position, dynamics, and fog affairs, and exchange their respective situations, dynamics, and coordinate the intention of avoiding the intention and action of action.

3

When the vision is harsh, the fishing boat is dense, the avoidance of difficulties, the complicated channel, and the captain's unsure of navigation safety, in order to ensure the safety of the ship's fog, under the condition of conditional permission, the captain has the right to anchor or hystewander, and do not voyage blindly.

Be full preparation before entering the fog

1. Before entering the foggy airline, the relevant provisions of the company's safety management system documents should be strictly implemented, and the company's fog navigation records should be done well. Essence The captain should urge the driver to inspect the various sailing instruments, fog and navigation lights to ensure the normal use of the fog, and urge relevant personnel to check the drainage and water dense equipment to make it in a good state.

2. Timely copy the weather forecast, meteorological fax, navigation warning, and fog and aerial aerial alarm. Prepare emergency plans under complex conditions and explain to relevant personnel clearly.

3. Drivers should maintain regular observation and observe carefully to determine whether the visibility is deteriorating from the changes in the lights, water antennas, wind direction, and targets, and whether they are entering the fog area.

4. The chief of the turbine should prepare the fuel of the host for changing the speed of the host.

Wushang should pay attention to

1

Entering the fog, the offshore distance of the route should be adjusted in a timely manner.

If the offshore distance of the design plan route is 2-3N Mile according to the good visibility, there should be 3-4 n mile between the route and the coast in the fog navigation, or even 5N Mile to ensure that there is sufficient room between the ships and the shore Essence

2

Sailing in the fog, the driver on duty should be done carefully.

In order to improve the accuracy of the calculation of the position of the ship, it is not appropriate to change the direction and speed when it must be frequently changed. When sailing along the coast, deep measurement is one of the important methods for checking and calculation. Sometimes, a certain class of deep line can be used as a sheltering aid line. Deeping data and time should be recorded near the corresponding calculation on the sea map to analyze the calculation of the track and the trend of estimates in the future. For the accuracy of calculating the position of the ship, there must be appropriate estimates. If necessary, you should draw and try to reduce the probability of the shipping area. Once the instrument fails, the ship position will become the only basis basis.

It should be used as much as possible to locate and navigate, especially the radar must be fully used.

At present, radar has become an indispensable navigation equipment when it is fog, and as the technical performance of ship radar continues to improve, it will definitely play a larger and larger role. In order to use radar to navigate and avoid in the fog navigation, it is required that the driver on duty is required to fully grasp the technical characteristics of the radar, be good at identifying various interference back waves, and quickly identify images and observe. Use radar to look at, and the appropriate distance file should be selected: ocean navigation can be available at 12-24 n mile distance stalls; sailing at 6-12N Mile at the coast; Essence Of course, even if the performance is better, after all, it is not as intuitive and reliable as vision, so you must not blindly rely on the radar and ignore the visual look. In order not to affect the observation and work of the driver on duty, a special person can arrange a special person to be responsible for radar observation and labeling. 4

Sailing in the fog should always grasp the actual visibility distance in the visibility situation at that time.

This can be found based on the visual vision, such as the method of detecting the distance from the radar while discovering the ship. If other objects that are not easy to discover the radar, you can write down the reading instrument reading when you find it, and then record the reader readings when you are horizontally. Visible distance. Of course, the visible distance in the fog will change according to the concentration of the fog. It is impossible to be fixed, and you should pay attention.

Pay attention to listening

The role of the sound in the fog is to warn the danger to the ship. The action of the sound changes with the factors of the weather (wind direction, wind, etc.), and cannot judge the distance from the distance according to the size of the sound. The sound is not straight in the air, especially near the sound source, and there is irregular phenomenon. Although near the sound source, in different positions, sometimes the sound is not heard, that is, there is a silent area. When there is fog on the sea near the fog station and there is no fog around, the fog police equipment may not work, and the ship cannot hear the fog. This situation often occurs at night. In addition, the fog whistle and the fog bell only work when there is wind and waves, and the sound changes with the size of the wind and waves. Therefore, navigation in the fog should not only be judged by the size of the sound or not to judge the safety of the ship's navigation. In short, when hearing the sound, you should pay attention to all the necessary risk aversion measures in the dangerous area. In the position you should hear without hearing, you should not be arbitrarily determined that it has not yet entered the danger zone.

When sailing at 2-3n Mile along the high and steep shore, according to the echo of the sound number of the ship, the distance of the ship can be roughly calculated, that is, when the sound is started, the stopwatch is started, and the stopwatch is stopped when the echo is heard. Take the speed of the sound of the sound and take 1/2 of the number of stopwatches.

Careful strengthening the lookings

Skilled watches must be able to find any small changes around the ship in time. E.g:

① When the wind direction and wind speed are stable, the waves weaken suddenly, indicating that the ship may be close to the coast or shallow water area of ​​the upper hand; on the contrary, if the wind and waves suddenly increase, it means that there may be a large bay on the upper coast;

② The navigation conditions have not changed, and the wind suddenly becomes smaller, indicating that the ship may be close to the high -steep shore;

③ The color and transparency of the seawater and transparency, if the seawater becomes turbid, it means that the ship may be close to the coast or river mouth of the bottom of the mud;

④ Floating objects, such as seagrass, seaweed, etc. on the sea, this is a sign of approaching the coast; if fishing gear, garbage and oil traces are found on the sea, it indicates that there are ships nearby;

⑤ Finding a large number of sea birds and sea beasts also indicates that it is close to land or icebergs.

What do you do when you do it?

Driver

Before the fog hit, the duty driver should seize the opportunity to use the sailing instrument to determine the ship's position. not

When the mist strikes, the driver should immediately take the following measures and report the captain:

（1）摇预备车，适当减低速度，并且将遇雾情况通知当值轮机员（缓慢速度的程度，应当根据当时的视距，船舶倒车的能力和灵活性决定，也就是在雾中航行， If you suddenly find a boat, you can generally require the half -distance from the boat to stop the ship forward);

(2) Start distribution of fog numbers;

(3) Send sailors to look at the head of the ship. If the wind and waves are too large and cannot look at the head of the ship, you can send him to look at it on the driver's desk;

(4) According to the situation, order all or part of the water door;

(5) Prepare all kinds of life -saving equipment in order to use at any time and prepare at least one lifeboat.

Captain

After the captain was informed of the fog, he had to go to the driver to personally instruct it immediately. When the driver is duty, the driver will inform the captain of the ship's position, the surrounding environment and the measures that have been taken. The captain should study the measures taken and pay special attention to whether the current ship speed is true. If the fog is durable for a long time, the captain can rest in the Haitu room after explaining the driver on duty according to the situation.

Motorist

Regardless of the speed of the ship, the duty machine should keep the boiler's full voltage, so that in an emergency, it can reverse at full speed.

Head of the turbine

The head of the turbine should be supervised and inspected at any time to ensure that the machine, electricity, furnace equipment and its system are operating normally.

All ship personnel

Keep the whole ship silent, the noise is strictly prohibited, and the sound of the hearing is prohibited. The lamps are prohibited from exposing the cabin at night.Data-nickName = "Chinese Maritime" data-alias = "China_msa" data-signature = "The Maritime Bureau of the People's Republic of China (Maritime Bureau of the Ministry of Transport) is an administrative institution directly under the Ministry of Transport, which implements vertical management systems to fulfill water traffic safety supervision.Administrative and law enforcement duties such as management, ships and related water facilities, preventing ship pollution and navigation protection.
