Rules for daily maintenance of boats
24 May,2022
1, daily fresh water cleaning the whole ship The boat is moored in water with high humidity and salt, and its surface is very easy to form salt crystals. This crystalline layer has the effect of accelerating the aging of the gel coat surface under light. Therefore, the boat should be washed with fresh water every day or every two days to wash away salt crystals and dust on the surface. In addition, the chemical composition contained in the feces of birds can also damage the gel coat layer, so it should be cleaned in time. After each cleaning, the hull should be dried immediately with a dry cloth (especially stainless steel parts and glass parts). If the water is left to dry naturally, it is easy to leave water stains, which will be difficult to clean up completely. 2. Polishing and waxing of the whole ship (to be completed before the middle of April each year) The working environment of the sailboat is relatively harsh, and it has been subjected to the combined effects of sea water, sunshine, dust, wind and rain for a long time. In order to slow down the oxidative aging of the gelcoat layer on the surface of the sailboat, the surface of the sailboat should be polished and waxed every year. The uniform high-quality wax film can effectively isolate the erosion of the gelcoat from sea water, air and dust. Let the surface of the sailboat shine again. Maintenance procedures: ① Wash and dry the hull ② According to the damage of the hull surface gel coat, select coarse wax/fine wax polishing ③ Rinse and wipe clean again ④ Polish with protective wax QQ screenshot 20180731135909.png 3. Indoor maintenance Due to the activities of personnel and the humid environment in which they are located, the indoor of the sailing boat also needs regular professional maintenance to ensure the quality of indoor furniture, clean indoor environment and mold intrusion. ① In the case of sailboats are not used, clean the indoor sanitation once a week, mainly for dust removal and garbage cleaning. ② Every six months for indoor furniture and floor waxing maintenance. ③ Carpet: The carpet in the cabin is cleaned with a vacuum cleaner once a week, and professionally cleaned every six months to remove bacteria, dust, and food residues and stains. ④ Toilet: The toilet should be kept clean and cleaned immediately after each voyage or when needed, including walls, floors, shower heads, faucets, handles, toilets, sewage outlets, etc. And according to the use of the situation, the choice of monthly or quarterly disinfection with disinfection water. 4. Cleaning of sails (for sailboats) Sail and hull, is also in a salty and wet environment for a long time, if not cleaned for a long time, crystallization in the crease of salt, will cause a certain degree of erosion on the sail surface, so every once in a while, the sail surface cleaning once. When cleaning, use a neutral cleaning liquid. After cleaning, dry the sails and put them away. 5. Bottom cleaning Because the hull is moored in the water for a long time, there will be marine organisms attached to the bottom of the ship, which not only reduces the speed, but also causes the loss of fuel. Therefore, the bottom of the ship should be cleaned regularly. Usually before the peak season of each year, the sailing boat is towed ashore, the bottom of the boat is cleaned of attachments, and before the sailing boat is launched, the bottom of the boat below the waterline is painted with anti-fouling paint. 6. Clean anti-collision ball Clean the anti-collision ball regularly so that it is always bright and clean. 7, timely maintenance In addition to daily maintenance procedures, cleaning and maintenance services are provided immediately after each use of the boat, rain, snow and other weather conditions.

Sailing maintenance details
(1) Daily cleaning: Rinse the surface of the sailboat with fresh water and wipe it with a rag. (2) Cycle cleaning: Take the running time of the sailboat engine as a cycle, maintain the engine of a new boat for 10 hours of operation, and then perform maintenance every 100 hours of operation.
What are the advantages of glass steel ship
FRP has the advantages of low density, high specific strength, easy forming, smooth surface, low water absorption, low thermal conductivity, seawater corrosion resistance, no insects, easy maintenance and repair, etc. When used to build fishing boats, it can reduce the dead weight of the hull by 20% to 30%, increase the loading capacity of fishing boats, reduce resistance, increase speed, save fuel and improve economic benefits. At the same time, it is also beneficial to keep fish fresh, easy to mass production and has low maintenance cost, long life. In addition, the stability and center of gravity of the FRP fishing boat are far away, the recovery torque is large, the stability is good, and the sailing ups and downs, recovery and safety are good in the big wind and waves. Modern scientific and technological development and Chinese and foreign experience has proved that FRP fishing boats have many advantages that wooden fishing boats do not have, especially in terms of displacement, speed, horsepower loss, formability and other aspects of performance, but also non-wooden fishing boats can be compared, so FRP is recognized as a more ideal fishing boat construction material.
What is a fiberglass ship?
The hull is constructed of glass fiber reinforced plastic as a material for the vessel. The displacement of FRP ships is usually below 500t, such as military minehunting boats, minesweepers, landing craft, traffic boats, etc. Civilian high-speed passenger boats, fishing boats, yachts, lifeboats, working boats and rowing boats, etc. Many of the navies of the new anti-mine ships, mostly using glass fiber reinforced plastic hulls, decks and cabins. The "hunting" class minesweeper built by Britain, with a full displacement of 750t, a captain of 60m and a ship width of 10m, is by far the largest glass fiber reinforced plastic ship. In the 1990 s, China built a number of catamarans with glass fiber reinforced plastic hulls, with a full displacement of 90t, a captain of 32m, a ship width of 8m, a ship speed of 30kn and a passenger capacity of 225. FRP lifeboats made in China have been exported to many countries.
Maintenance of glass steel ship
FRP is made of synthetic resin as the matrix and glass fiber as the reinforcing material. It has similar strength with steel, superior performance of water resistance and corrosion resistance, and its surface is smooth and beautiful as a mirror, and it can be molded as a whole. But it also has some shortcomings, such as small stiffness, poor wear resistance and so on. In particular, there are many factors that affect the quality (such as the quality of raw materials, the technical quality of operators, production conditions and environmental factors, etc.), which makes the quality of similar products very different. Compared with steel and wooden ships, FRP ships have the characteristics of less maintenance, which is determined by the superior performance of FRP itself. However, FRP, like all materials, also has aging problems, except that the aging process is relatively slow. Even if gel coat resin is applied to the surface of the ship to form a protective layer, it will be damaged and thinned under frequent friction and environmental erosion due to the thickness of only 0.3-0.5mm. Therefore, FRP less maintenance is not without maintenance, proper maintenance can not only maintain a beautiful appearance, but also extend the life of FRP boats. In addition to the maintenance of machinery and equipment according to the regular, the maintenance work points of FRP boats are as follows. In addition to the maintenance of machinery and equipment according to the regular, the maintenance work points of FRP boats are as follows: Avoid contact with sharp, hard objects. Friction and collision between FRP hull and shore stones, concrete structures and metal components will cause scratches and other damages. Protective measures should be taken. For example, anti-collision and wear-resistant metal and rubber fender materials should be set up at the bow, wharf and side edges that are often subject to friction, and wear-resistant rubber and plastic soft materials should be laid on the deck. Found damage, timely repair. Check the hull frequently, such as resin peeling, deep scratches, exposed fibers. It must be repaired in time, otherwise the damage will be accelerated due to the infiltration of water. When not in use, especially in the cold winter season, it should be placed ashore. Because FRP has certain water absorption, water can gradually penetrate into the interior along the tiny channel of glass fiber and resin interface, thus gradually decreasing the strength of FRP. The infiltrated water will freeze when cold, expanding the seepage channel and causing greater harm. Therefore, when the boat is not in use in winter, it should be set aside from the water bank to volatilize the infiltrated water and gradually recover its strength. This can prolong the service life of the boat. After landing, the boat should be cleaned first, put it away with liners, and usually put it indoors. If it is placed outdoors, it should be covered with tarpaulin cloth and often ventilated to prevent moisture.

Folding Channel and Port Service Vessel Type
16 Jun,2020
Folding channel and port service ship: 1 buoy tender, a buoy tender ship, is also called "marking ship". A ship equipped with equipment such as cranes and winches for lifting and releasing navigation marks to carry out navigation mark arrangement, patrol inspection, supply, repair and maintenance at the channel and its nearby reefs, shoals and rocks.
What's the use of sails on sailboats
The role of the sail: the angle can be adjusted according to the direction of the wind to effectively use the wind energy to push the ship forward. A hide, canvas, or other fabric that is hung from a mast and spread out to use wind to propel a boat on water. The types of sails, according to the different positions, are divided into bow sail, stern, upper sail, inclined sail, four-angle sail and triangular sail.
Types and Stories of Engineering Ships
Folding cloth cable boat In 1972, after the normalization of diplomatic relations between China and Japan, in order to strengthen the communication between China and Japan, the two governments agreed to sign an agreement on the construction of a Sino-Japanese submarine cable in Beijing in May 1973. The Sino-Japanese submarine cable runs 872 kilometers from Nanhui County, Shanghai City, China to Lingbei Town, Kumamoto Prefecture, Japan, with 480 telephone lines.
