And it captures the highs and lows of a time that saw both the arrival of the city’s biggest ever cruise liner visitor, and a closure threat to the iconic Harland & Wolff shipyard.
Future episodes will explore the work of the harbour’s control room managers and shipping agents who oversee the movement of a dizzying array of goods in and out of the port.
That’s not to mention the skilled harbour pilots and crane operators who help to ensure its safe workings day in and day out.
The first episode of Belfast Harbour: Cruises, Cranes and Cargo screens Tuesday 14 April at 10.45pm on BBC One NI. The Belfast Telegraph has more on the story HERE.
