摘要
The disclosure provides a system and method for installing subsea equipment, such as a pipeline and equipment associated therewith in a target area, generally having restricted overhead access. An anchor can be installed in the seabed and can include one or more sheaves. A pipeline can be provided, which can include related equipment and/or one or more coupling devices situated remotely from the anchor relative to the target area. A winch wire can be provided and is adapted to be directly or indirectly coupled across at least a portion of the target area to the pipeline. A transfer sling having a pull wire and an initiation wire can be coupled between the winch wire and pipeline to assist the winch wire pulling the pipeline into the target area and transferring a pipeline force from the sheave to the anchor independent of the sheave.
