A task such as inspection is performed at a subsea location by positioning a functional unit such as an unmanned underwater vehicle to perform the task. When positioned to perform the task, the unit is then in a shadow region where wireless control signals from a subsea control transmitter are obscured by a subsea obstacle. Consequently, control signals arre transmitted wirelessly through water from the control transmitter to an autonomous underwater vehicle (AUV) positioned outside the shadow region and are relayed from the AUV to the unit to control the unit to perform the task. The unit can be tethered to the AUV or can communicate with the AUV wirelessly. The AUV can move itself to improve wireless communication with the subsea control transmitter and optionally also with the unit.
