Abstract
In one embodiment, the subsea deployment system may be used to install flying leads with integral buoyancy. In another embodiment, the subsea deployment system may be used to install flying leads with separate buoyancy modules. The installation sling assembly may be used with the subsea deployment system or with other systems to deploy flying leads subsea. The universal removable cartridge may be interchanged for use on a horizontal drive unit and a mud mat.
