<p>A method of joining two portions of an underwater pipeline laid on the bed of a body of water to conduct fluid and/or gas, the method including : joining a telescopic sleeve (39), having a first coupling head (40), to a first end (35) of a first pipeline portion (31) above the body of water (3); laying the first end (35), the telescopic sleeve (39), and the first coupling head (40) on the bed (2) of the body of water (3); joining a second coupling head (42) to a second end (36) of a second pipeline portion (32) above the body of water (3); laying the second end (36) and the second coupling head (42) on the bed (2) of the body of water (3), close to the first coupling head (40); roughly aligning the first and second coupling head (40, 42) in the body of water (3); and clamping the first and second coupling head (40, 42) to each other in the body of water (3).</p> |
