Development of an underwater oxy-arc cutting method of tubes and application to cutting of tubes of 1 m diameter and 16 mm thick used for construction of bridge pier at water depth of about 10 m. As a successful result was obtained, for the purpose of underwater cutting of beat-in-tube which is employed for preventing overturn of offshore platform, an experiment of underwater cutting using high pressure chamber was at this time carried out. Tubes used were 1 m diameter and 35 and 45 mm thick. Cutting at deep water depth was obtained the same result that at shallow water depth, however cutting oxygen pressure must be added 5-8 kg/cm2 to water pressure corresponding water depth. (Wassmann)
