Caisson (kan) Worker
せんかんこう
Industry & Occupation
Classification
Summary
Specialized civil engineering professional who enters caissons in caisson construction projects, etc., and performs structure installation, concrete pouring, and other tasks under pressurized and decompressed management.
Description
Caisson workers mainly enter the interior of caissons (pressure chambers) in caisson construction projects, etc., and perform civil engineering tasks in underwater or wet environments while adjusting pressure. Tasks include assembly and installation of steel caissons, welding, concrete pouring, topping work, interior finishing, etc., and they also handle heavy equipment operation and surveying. Workers strictly adhere to pressurization and decompression management and perform work after receiving hyperbaric work special training based on the Occupational Safety and Health Act. Since it involves long hours in high-pressure environments and work in confined spaces, physical strength and mental stress tolerance are required.
Future Outlook
While stable demand is expected from measures against aging public infrastructure and foundation work for offshore wind power generation, a shortage of workers is a challenge due to the harsh working environment.
