Air compressor has contributed to the shipbuilding and ship maintenance for a long time. Air tools are higher efficiency in the manufacturing process. Pneumatic hammer is used for transmission the spike when paving the keel, grooving on the metal sheet before welding, cutting the flakes at the welding point, fixing them with rivet and filling and avoid leakage. Grinder driven by air compressor has thousands of application for surface finish. During the painting process of shipbuliding, the efficiency of spray coating with air compressor is higher 20 times than the handbrusher’s. Pneumatic rimer and drilling machine are also need the compressed air.

Because most of the job are finished outside, shipbuilders find out compressed air is very convenient and help them to blow off the snow, rain and dust in working site. It is easier to test the welded joint by blowing off the water gathered in the welded joint.

Pneumatic motor, crane and diesel engine are started by air compressor, such as operating dry dock, salvaging sunken ships and other jobs under water.

Vacuum spray will clean the salt on the surface of aircraft carrier and hold of cargo ship. Pneumatic controlling by air compressor is widely used in tug of the harbour and naval vessel. The latest application is using compressed air motor to push the torpede and launch the torpedo by pneumatic tube.
