ABSTRACT:
A method is disclosed that comprises the steps of preassembling the connector pipe in a support; coupling a frame to the pipeline at or towards an end thereof such that the location of at least one part of the frame is known with reference to the throughbore and the end of the pipeline; engaging the support with a portion of the frame; substantially aligning the connector pipe with the end of the pipeline; and connecting the connector pipe to the end of the pipeline. A cutting tool is also disclosed that can be coupled to a portion of a guide means and used to cut the pipeline at a predetermined distance from the guide means such that the end of the pipeline is created. A remotely operable vehicle can be used to remotely actuate and control the connection of the pipe and the pipeline.
