Abstract
A method of assembling a pipeline at a seabed location comprises landing a connection tool (10) on the seabed over a free end portion of a first pipeline section (12) already placed on the seabed. The connection tool is locked to the free end portion of the first pipeline section, a lower end of a second pipeline section (26) is connected to the connection tool via an initiation line (68). While applying tension to the initiation line against reaction force of the connection tool, at least a lower end portion of the second pipeline section is landed on the seabed with the lower end facing a free end of the first pipeline section. The lower end of the second pipeline section is then pulled into mechanical engagement with the free end of the first pipeline section.
