Description

technical field

[0001] The invention relates to an installation method and device for an underwater manifold, in particular to a swing installation method and device for a typical underwater manifold. Background technique

[0002] In recent years, with the continuous development of the economy, the demand for oil and gas resources in countries around the world is increasing. In order to obtain more oil and gas resources, people have turned their attention to the deep sea. Subsea production system has been widely concerned and applied by major oil companies because of its significant technical advantages and considerable economic benefits. Installing a large subsea production system also faces some problems as the water depth increases. The traditional installation method is to use steel wire ropes to place the underwater production system underwater, but its disadvantage is that as the water depth increases, most of the tension of the steel wire ropes is consumed by its ow...
