Abstract
A system can include a source and a front float coupled to the source. The front float can include a winch configured to adjust a position of the source. The front float can include a control unit configured to control functions associated with the front float. Lead-ins can be coupled to the front float and the source and configured to accommodate transfer of electrical energy between the front float and the source.
