A method of deploying a subsea line utilizes a subsea deployment unit. A drum wrapped with the line is mounted to the unit. The unit is lowered on a cable into the sea from a surface vessel. An ROV is lowered on an umbilical into the sea and brought into engagement with the unit. The ROV provides thrust and guidance to move the unit along a desired path above the sea floor. The ROV also supplies power to the motor of the unit to cause the drum to rotate and deploy the line from the drum. The ROV disengages from the unit and connects the ends of the line to subsea components. |
