While operating, the tether handler's job is to ensure the safety of the tether and that its impact on piloting the ROV is minimal. This usually means that the tether will be deployed and retrieved many times during a job. As seen here, even with a TDS, it is easy to manage the tether using one of the previously described hand coiling methods. Usually, the tether will simply be deployed as fast as necessary while the ROV is navigated to the area of operation, and then while the ROV conducts its mission the tether will need to be managed. When the project work has been completed, the tether will need to be retrieved. If the pilot is flying the ROV back, the tether should not be pulled too quickly to impact the piloting. If the operating site is deep, sometimes it might be better to apply vertical up thrust and haul the ROV up by the tether.
