Abstract: A method of connecting underwater pipelines by installation of a pipeline on a seabed fixed frame; laying of an outboard pipeline by a lay barge; installation of a subsea winch with the frame; actuation of the winch by a ROV to unwind the cable of the winch, aided by another ROV bringing and connecting the end of the cable to the outboard pipeline; winding of the cable and following deflection of the outboard pipeline up to the frame; installation of a metrology system to define the distance and angular misalignment between the two pipelines' ends to be connected; assembly of a connection system with telescopic capabilities using the measurements of the metrology system and using a dedicated frame installed on board a support ship; installation of the connection system on the seabed fixed frame and connection of the connection system with the pipeline ends.

Abstract: A method and apparatus for connecting underwater conduits and more specifically, to a method and apparatus which is capable of performing the diverless connection of underwater flowlines and connection of these flowlines to underwater structures such as flowline bases, xmas trees and templates. The connection of underwater conduits facilitated by the use of a remotely operated vehicle and connection apparatus both being launchable and recoverable by a support vessel. The connection apparatus adapted to mount on at least one of the underwater conduits and the connection apparatus allowing for docking of the remotely controlled vehicle which then captures and draws a second conduit to form a continuous flowline.
