What Does a Marine Technician Do?

Navigation science and technology mainly study the theory, method and art of how ships can safely and economically sail from one place to another on an ideal course. Navigation technology is a comprehensive applied science with a long history, rich content, and strong practicality.

Navigation Technology

(Knowledge and skills in marine navigation)

The bravery of the early voyagers is well known, and they constantly make up for the backward sailing technology of the old era through great innovation. Among the early Vikings, the captain was very familiar with the sea and the natural objects in the sea, such as birds, fish, currents, driftwood, seagrass, aqua, icefield reflections, clouds, and wind. In the 9th century, the famous Nordic navigator Fletcher always put a crow on the boat. When he felt that the boat was about to approach the land, he would fly the birds in the cage. If a bird flies aimlessly around the boat, it means that it is still far from the land; if the crow flies in a certain direction, he will sail the boat and follow the direction the bird flies, which is often driven to land direction. Of course, this method works only when it is relatively close to land.

At that time, navigators always kept a relatively close distance from the shore, and they could see the characteristics of the land to determine whether the course was correct. They usually sail during the day and anchor in the harbor or anchor on the sea at night. Most of the merchant ships in European cities like the Middle Ages used coasts, and they preferred to sail along Spain, France and Italy.

The development of maritime history is inseparable from the progress of maritime science and technology. Navigation has evolved from craftsmanship to science and technology. The book "History of Navigation" in the United Kingdom states: "Navigation is the art of guiding ships to safely move from one surface of the earth to another."

In the second half of the 20th century, with the rapid development of the whole science and technology, the progress of marine science and technology has changed rapidly. Its important signs are as follows:

Large ship

In the 1960s, 10,000-dwt ships could be called "10,000-ton giant ships". At the end of 2000, there were hundreds of very large tankers (VLCC) of 100,000-dwt in the world, including three 500,000-dwt Extra large (ULCC) tanker. Currently the largest bulk carrier is 360,000 dwt. Container ships have also become larger and larger in recent years. 5000TEU, 6000TEU, 7000TEU and 8000TEU container ships have been put into use successively. 9000TEU and 10000TEU container ships are under construction and development. In the second half of the 1990s, European and American shipowners continued to build large luxury cruise ships. From 1998 to 2002, an average of 13 ships were built, most of which were 140,000 gross tonnage.

Ship specialization

In the past, marine transport vessels were mainly passenger, cargo and oil tankers. For nearly 20 years,

When the radio telegraph began to be used for ship-to-shore communication, the era of the so-called "God Boss, Captain Second" ended. Shipping companies and shore-based navigation services and management departments can influence, assist and control the navigation activities of ships through radio communications.

1) Radio Navigation Warning System

(RadioNavigationalWarning) The navigational warning system and navigational notice are to notify all ships in a timely and accurate manner of any changes that occur or are about to occur in the sea area and waters that may affect the safety of navigation and operations, so that they can take appropriate measures or maintain alert To ensure the safe navigation and operation of the ship. Designated by national maritime safety authorities

Due to the harsh marine weather and sea conditions, the complicated navigation environment and limited ship conditions, and the negligence and mistakes of Shanghai personnel, frequent shipwreck accidents often cause major loss of life and property at sea and serious pollution of the marine environment. Shipwreck accidents are generally classified into collisions, wave damage, reef strikes, strandings, fires, explosions, sinking, and disappearances. As far as the catastrophic accident in the 20th century is concerned, it is well known that the British luxury passenger ship Titanic sank after hitting an iceberg in the North Atlantic on April 15, 1912, killing more than 1,500 people. But what many people don't know is that on September 28 of the same year, the Japanese passenger ship Kicker Maru was sunk along the coast of Japan, killing more than 1,000 people.

In the 20th century, there were more than a dozen shipwrecks that killed more than 1,000 people. December 20, 1987

From the middle of the 20th century, with the large-scale exploitation of oil and the development of the chemical industry, the number of ships transporting oil and chemicals at sea has increased, and the scale has become larger. Shipwrecks often cause oil or chemicals to leak and seriously pollute the ocean. Environmental and ecosystem events are increasing. E.g. March 1967

Undergraduate nautical technology professional training objectives: This professional training has the knowledge of marine ship driving, ship transportation management, etc., and can engage in marine ship driving and operation management in marine transportation enterprises and institutions, in line with international and national seafaring crew competency standards. Senior nautical talent.
