Description

technical field [0001] The invention relates to a three-dimensional action implementing device, in particular to a three-dimensional action implementing device applied to underwater dry tanks in the field of offshore oil. Background technique [0002] In offshore oil and gas development projects, in order to transport oil and gas to land or oil storage systems, a large number of submarine pipelines are laid on the seabed. Under the action of external forces or environmental factors, these pipelines will be deformed, broken and leaked during laying and use. If it is not repaired in time, it will cause huge economic losses and environmental damage. Therefore, timely, effective and reliable maintenance of underwater pipelines is an important project. [0003] At present, although there are a few countries with developed offshore oil industry in the world that have dry maintenance capabilities, there are obvious defects in the existing dry tank system. A cabin that can form a ...
