The ferry and the tanker

Just before 1pm today, I watched the fuels tanker Solway Fisher coming into port. About 15 minutes later, she was seen leaving again. Checking the local AIS, the reason why became clear.

The blue blip is the ferry, Isle of Lewis, which is coming into for its customary lunchtime call. I am told that it is not permissible for a tanker to be discharging whilst the ferry is also discharging and embarking passengers, only a few dozen feet away. I’m expecting the tanker to return to its intended berth alongside pier no 2 after the ferry has left again, shortly before 2pm.
