Silence descends in the Rolls-Royce remote operations centre as master Rene Malmstrom takes control of the 28-metre Svitzer Hermod (built 2016) from his counterpart onboard the tug.

Malmstrom navigates slowly across the test area, his 180-degree view displayed on a video wall almost affording better visibility than on the actual bridge. Later he puts the vessel through a minor push of another tug before finally berthing at the pier outside the operations centre.
