Detailed Description
The following description and the drawings sufficiently illustrate specific embodiments of the invention to enable those skilled in the art to practice them. Other embodiments may involve structural, logical, electrical, process, and other changes. The embodiments represent only possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in, or substituted for, those of others. The scope of embodiments of the invention encompasses the full ambit of the claims, as well as all available equivalents of the claims.
In some illustrative embodiments, as shown in fig. 1-3, a flexible boom suitable for offshore production includes a first boom 5, a second boom 6, and a damping assembly 101. One end of the first arm support 5 is fixedly connected with the ship body 102, and the other end of the first arm support is fixedly connected with the second arm support 6 through the buffer assembly 101. The first arm support 5 and the second arm support 6 are positioned on the same straight line, and the angle is 180 degrees. The second boom 6 is positioned under water. One part of the first arm support 5 is positioned on water, and the other part is positioned under water. The length of the first arm rest 5 is larger than that of the second arm rest 6. The ratio of the length of the first arm support 5 positioned at the underwater part to the length of the second arm support 6 is smaller than 1, and the depth of the tail end of the second arm support 6 is smaller than 7000m. The depth of the end of the second boom 6 refers to the depth of the end of the second boom 6 under water.
