Aberdeen Harbour on the north east coast of Scotland, is one of Britain's oldest businesses and one of Europe's most modern ports. It is the heartbeat of the offshore oil and gas industry. Every year, more than eight thousand boats pass through the harbour waters, helped by the hidden world of the men and women who keep it running 24 hours a day, 365 days a year. This is their story.
In this episode: It's very rare to see the harbour closed, but abnormally high winds mean it's just too dangerous to stay open. Everything has to stop, but the delays cost thousands. Boatmen Alan Cowper takes his daughter to try out for Scotland's under-15 football team but faces an excruciating wait to hear whether she gets in. VTS controller Ralph Greig has decided a change of career is required, while out at sea on the Bibby Sapphire, saturation diver Terry Dearlove begins the lengthy process of decompression. With a North Sea storm looming, will he get back to Aberdeen in time to get home for his daughter's 18th birthday?
