[0002] With the continuous improvement of the requirements of the International Maritime Organization (IMO) for energy conservation and emission reduction, reducing ship energy consumption has become the development trend of the ship industry. Among them, as a cutting-edge technology with remarkable energy-saving effects, the air lubrication drag reduction technology uses air bubbles to reduce the resistance between the hull and the sea, has wide adaptability and remarkable energy-saving effects, and can reduce carbon dioxide emissions by about 10% to 15%, attracting much attention from shipowners, shipyards and design units. The specific working mode of this technology is that first, air is quickly pumped out from the small holes on the outer shell of the ship. At this time, the honeycomb-shaped bubbles will quickly combine and form a 1 cm to 2 cm thick air layer outside the ship's hull. Since the resistance of air is much smaller than that of water, the resistance during the ship's navigation can be reduced, achieving the effect of saving energy. The system consists of an air compressor, a gas release unit of the outer bottom plate of the ship, and a series of pipelines and accessories. Due to the structural form, welding requirements of the gas release unit of the outer bottom plate of the ship and the characteristics of ship construction, it is necessary to solve the tightness test plan and tooling facilities for the release ports of the gas release unit of the outer bottom plate during construction to meet the requirements of ship tests.
