Giant primary-coloured oil platform supply vessels fill almost every bay in Aberdeen’s tightly packed city centre port. For the two marine traffic controllers sitting at the very top of the glass tower overlooking the congested harbour, it is like an enormous high-stakes round of the classic computer puzzle game Tetris.
“It’s been busy all morning. We’ve only got a couple of berths free [in the north harbour] and the south harbour is full already. There are a few vessels out at sea waiting for berths,” says one of the controllers.
