A task such as inspection is performed at a subsea location by positioning a functional unit (50) such as a UUV to perform the task. When positioned to perform the task, the unit (50) is then in a shadow region where wireless control signals from a subsea control transmitter are obscured by a subsea obstacle. Consequently, control signals are transmitted wirelessly through water from the control transmitter to an AUV (30) positioned outside the shadow region and are relayed from the AUV (30) to the unit (50) to control the unit to perform the task. The unit (50) may be tethered to the AUV (30) or may communicate with the AUV (30) wirelessly. The AUV (30) can move itself to improve wireless communication with the subsea control transmitter and optionally also with the unit (50).
