It is a method for cutting and removing structures such as concrete underwater.
The completely wet underwater wire sawing method is a technique for cutting and removing structures such as concrete underwater when dismantling them. It allows for space-saving operations at great depths and is not affected by working depth (working depth from 0m to 45m). Since the wire saw machine is completely installed underwater, there are no human-related accidents, and because the cutting machine itself is underwater, work can continue even if the work vessel is swaying. It can be performed with a minimal length of diamond wire for cutting, and due to the compact size of the machine, CO2 emissions are significantly reduced. 【Features】 ○ Equipment can be loaded onto small vessels for preliminary cutting ○ Monitoring is done via surveillance cameras, allowing for immediate response to issues ○ Biodegradable oil (ISO 6743 Class L) is used for work ○ NETIS registration number KKK-090001-A (registration period has ended) For more details, please contact us or download the catalog.
