Abstract:
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, having a first coupling head, to a first end of a first pipeline portion above the body of water; laying the first end, the telescopic sleeve, and the first coupling head on the bed of the body of water; joining a second coupling head to a second end of a second pipeline portion above the body of water; laying the second end and the second coupling head on the bed of the body of water, close to the first coupling head; roughly aligning the first and second coupling head in the body of water; and clamping the first and second coupling head to each other in the body of water.
