Abstract: The disclosure provides an installation method to deploy the flexible pipe below the water, utilizing supporting equipment between a flexible pipe and intended connections. In addition, the method of connection and pull down can maintain control of the flexible pipe subsea throughout the method with limited or no surface intervention. This installation method provides a redundancy as the connector approaches in a subsea connection in at least one embodiment. The method utilizes combinations of buoyancy elements, hand-off sequences, and pull down equipment, such as subsea winches and wire rope, to accomplish such connections with limited or no surface intervention.

Abstract: The disclosure provides an installation method to safely and routinely deploy the flexible pipe below the water, utilizing supporting equipment without damage between a flexible pipe and intended connections. In addition, the method of connection and pull down can maintain control of the flexible pipe subsea throughout the method with limited or no surface intervention. This installation method reduces risk of damage to the flexible pipe and the connection elements during the installation and provides a safety redundancy as the connector approaches in a subsea connection in at least one embodiment. The method utilizes combinations of buoyancy elements, hand-off sequences, and pull down equipment, such as subsea winches and wire rope, to accomplish such connections with limited or no surface intervention.
