The Proteus is brand new, having been delivered earlier this year. Described by the World Maritime News here as "primarily for oil and gas and offshore renewable clients, performing cable and pipeline pre- and post-installation route surveys around the coastline of the UK and Northern Europe", she raises the same questions as we asked about the Tethra - is she here to survey for the high-speed internet connection that's been promised us or, as one commentator suggested on this blog, is she looking for the gold from the Spanish Armada ship which sank off Tobermory? The latter seems less likely as the search seems to be concentrated in Tobermory Bay - see Scotsman article here. Or is she here for another reason? Is there oil in the Sound? Are we going to be very, very rich?
