Management training program / plan, originally meaning management training program, is a set of training system researched and developed by the United States in 1950s to effectively improve the level of enterprise management
after 11 times of revision, it has become one of the classic management training in the world. So far, millions of managers around the world have been baptized by MTP. The system plays an immeasurable role in promoting the rapid economic development of Europe, America and Japan
In the late 1990s, MTP was introced to the mainland from Japan and Taiwan, providing a systematic and complete training program for management in the process of enterprise development, which has been widely used by enterprises all over the world and achieved good results
expansion data
MTP training each content is aimed at the most elite practical management skills to carry out, save a lot of unnecessary theory. Because the enterprise managers should master the "how to do it" rather than a bunch of theories that they don't know how to use. Therefore, MTP training is by no means general, but to let the trainees quickly grasp the key points of actual combat. These are the design spirit of MTP
Due to the effectiveness of MTP in the all-round development of managers' management ability, MTP has been widely introced and implemented in Japan, Taiwan and all over the world3.
There are 19 ports. The main international ports are port of Klang, port of Penang, port of Johor, port of Malacca, port of Huangjing, port of Tanjung Palapas, port of Kuantan, port of kamamawan, port of Kuching, port of minlu and port of Nam
1. Port of Klang is an important port in Southeast Asia and Malaysia, located in the northeast of Malacca Strait. It is Malaysia's maritime gateway and the country's largest port. The port is located on the west coast of the Malay Peninsula, about 6 km southwest of basheng City, about 38 km southwest of the capital Kuala Lumpur
2. Penang Port is located in the northeast corner of Pinang on the western coast of Malaya Peninsula in Malaysia, near the northeast entrance of Malacca Strait. Also known as George Town, it is the second largest port in Malaysia and a famous entrepot trade port
Port of Tanjung pelepas (PTP) is located at the southern end of the Malaysian Peninsula, on the edge of Singapore, which is the throat of world shipping. Maersk's westward route to Europe, Africa, the Middle East, etc. all passed in Tanjung Palapas port, which shows the importance of this port Gujin port is located in the lower reaches of Sarawak River in the southwest coast of Sarawak, Malaysia, and is the largest port in Sarawak. Kuching is not only the capital of Sarawak and the center of politics, economy and transportation, but also the material distribution center of Sarawak. The main instries are sawn wood, soap, clothing, shoe-making and agricultural procts processing, and has a world-famous antimony smelter Johor port has always been a port with bulk cargo transportation as its main business, mainly exporting wood, palm oil and rubber, and then developing the export of soybean, wheat, corn and other food crops, as well as the import of fertilizer and silicate, as well as a large number of liquefied gas and petroleum procts4. 11
when a ship travels for a long time, it must be able to generate its own fresh water boiler, machinery and washing. The installation of fresh water generator transforms sea water into fresh water
distillation is the most common process. Using the heat of the engine, sea water evaporates into steam. It is then taken to a cooling zone where the steam condenses into water and is distilled again. The cooling part is made of tubes or plates, and seawater is used as the coolant
the air evaporation chamber in the chamber is evacuated to the nearby vacuum, so that the boiling point of water is reced. Then it becomes possible to evaporate seawater at a temperature of about 40-39 ℃; c<

centrifugal pumps are usually used. The high speed rotation of the impeller in the pump housing is about 1450 rpm. The water is driven from the center to the edge by centrifugal force. Through special shape spiral case or through diffusion plate. High speed water flow is converted to a lower speed, pressure water discharge pump
oil pumps are usually positive displacement pumps. Because the moving parts are closely matched, oil is needed to provide a lubricating film between the surfaces
some common positive displacement pumps use gear pumps and screw pumps on ships. Piston and plunger pumps, vane pumps, and vane pumps. The relief valves of these pumps are installed on the discharge side

the car clock is a pointer and processing device used to convey commands between the bridge and the engine. room. Orders like Hui speed, back into three, stop, some examples of orders. When the bridge personnel handle the telegram on the bridge, there is a corresponding movement of the pointer, the cabin telegram and the sound of the gong. The engineer manipulates the engine cabin to hear Gong and the pointer move, and will acknowledge the same signs of order processing through the move. Gong will stop sounding
14
when the ship arrives at the port, it is ready to operate. This is a critical period as any loss of propulsion, or steering, can result in collision, ground or other damage
the navigation officer on the bridge will give the engineer one hour's notice in the engine room to prepare for the operation, and the ship is still moving to the port. The messages are recorded in a mobile book, showing accurate time notifications. Later, the entire maneuver, all orders through the car clock are also recorded in this book
15
as the ship approaches the port, the order may come from the bridge and slow down to a certain speed. Normally, the ship will stop assisting the pilot. The pilot will mark the location of local knowledge, shallow areas, tides and currents. Pilot wil1 gave orders to the cabin since then
tugs usually assist ships along the docks of the port. These are the pilots' orders. The crew of the ship will come ashore before and after. The ship will continue to reverse small steps and eventually be tied to the dock safely
once the ship is tied off the bridge, the final order will be completed<

the engineer must be ready to operate the engine in an hour's notice. Additional generators must be started and synchronized in order to have sufficient capacitance to prevent power failure e to heavy load generators. In this period of artificial intelligence, many other machines will start, such as mooring winch, cargo winch, cargo crane, anchor winch, etc
the starting air supply to the main diesel engines is open. Mr. reservoir is sharing the maximum capacity of air that is used for engine starting. Engine fuel is graally changing from C heavy oil to light diesel engine, with the expected loss of heated fuel e to deceleration of the main engine
17
among them, the most important knowledge is that marine engineers must know how to prevent and delay fire. There should be a fire on a ship, and there are few other places to go except the surrounding waters. Oil tankers carry easy fuel. The engine uses fuel. The boiler is rolled up with oil or gas. Gas welding or cutting repair work using flammable gas. There is a strong possibility of fire if they are not careful or alert. To understand fire can start, we must know the concept of fire triangle. Fire can only start as fuel, heat and oxygen. The three sides of the triangle represent this fact. If one of them is absent or deleted, the fire does not exist. To prevent a fire, the best way is to isolate or, better yet, all the people

a typical modern ship relies on fuel combustion engine. Whether it's a steamship powered by a steam turbine, or an internal combustion engine powered by a diesel engine, a lot of fuel is consumed ring sailing. A ship must store enough fuel to last throughout the voyage. It would really be a disaster if the ship was caught in the middle of the sea without fuel
because of its importance, the chief engineer is directly responsible for the fuel. He has to track its usage and its remaining quantity at any time ring the voyage. He has ordered enough quantity to use it timely and efficiently. Because of the economy, he can't accept too much extra fuel because it will depress the economy
refuelling is a term used to receive heavy oil, diesel and lubricants directly into a ship's tank for its own engine
