FRP is a new shipbuilding material and an important part of modern material innovation. FRP has not been used in shipbuilding for a long time, but it has shown its strong vitality and broad development prospects. FRP ships include not only small boats, such as fishing boats, yachts, high-speed passenger ships, business boats, traffic boats, speedboats, lifeboats, painted boats, sailboats, sports boats, minesweepers, etc. Careful preservation and maintenance of fishing vessels can reduce the loss

1. Corrosion of the hull structure on the water, the part on the water of the hull mainly includes the deck, superstructure and freeboard. The above water parts of these ships are mainly affected by rain and snow, sea water spray and ocean atmosphere, and these factors are the important reasons for the severe corrosion of the hull on water. In the marine atmosphere, there are a lot of nitrogen compounds, which make the condensation water aggravate the damage to the hull structure. On the other h

We know that the sea water has strong corrosivity to the ship, and the marine life has strong adhesion to the ship. After the ship is launched for a period of time, a lot of barnacles, algae and other marine organisms will be attached to the hull, and rust spots will appear. On the other hand, the presence of these warships increases the speed of the ship's flight and, on the other hand, increases the resistance of the ship's flight. Marine attached organisms refer to the animals, plants and mic

Fishing vessels can be divided into marine fishing vessels and inland fishing vessels according to different working waters. (1) marine fishing vessels. Marine fishing boat is a kind of vessel used to capture aquatic economic animals and plants in the ocean. According to the operation mode, it can be divided into trawler, purse seine, tension net, fishing boat, gill net, etc. The requirements of seaworthiness of marine fishing vessels are high. In order to increase the time of marine operation,

According to the raw materials of fishing vessels, fishing vessels can be divided into steel fishing boats, wooden fishing boats, glass fiber reinforced plastic fishing boats, steel wood mixed fishing boats, steel mesh cement fishing boats and other raw materials fishing vessels. Next, we will first introduce the differences between wooden fishing boats and steel fishing boats. Wooden fishing boat is made of wood as the primary material. Compared with the fishing boat made of steel, there are ma

Ship Lofting linear lofting: the craft lofting and the machine (computer) lofting are divided into craft lofting and machine (computer) lofting. The craft lofting is generally 1:1 share. The sample platform needs to occupy a large area, which needs more manpower and material resources for shipbuilding, and is less selected. Machine lofting, also known as mathematical lofting, relies on advanced technical software to loft the hull, with high accuracy and no occupation of field And manpower, more
