It has been developed in several phases.
Phase I embraces a pipeline with a diameter of 40 inches, running for 814 kilometres from the Sleipner area of the North Sea to a receiving terminal at Zeebrugge in Belgium.
In addition comes a 30-kilometre line with a diameter of 30 inches from the Sleipner area to the Draupner S platform. This first phase of Zeepipe became operational on 1 October 1993.
Phase II embraces the 40-inch Zeepipe IIA pipeline, running 303 kilometres from the Troll Gas processing plant at Kollsnes near Bergen to the Sleipner area, and the 40-inch Zeepipe IIB line which runs for 304 kilometres from Kollsnes to Draupner E.
Contractual gas deliveries from Troll began on 1 October 1996 via the Kollsnes facility and on through Zeepipe IIA. Contractual deliveries through Zeepipe IIB started on 1 October 1997.
