Zeepipe
Encyclopedia
The Zeepipe is a natural gas transportation system to transport North Sea
natural gas to the receiving terminal at Zeebrugge
in Belgium
.
The total costs of Zeepipe system is around 24.2 billion NOK. It is owned by Gassled
partners and operated by Gassco
. The technical service provider is Statoil
. The Zeebrugge receiving terminal is owned by Fluxys
(51%) and Gassled partners (49%).
Originally, there was a plan to build a intermediate service platform to the pipeline to tie-in future compression facilities and to enable the pipeline to be pigged in two sections. However, due to technological development it is possible to serve the pipeline as one pigging
segment and the need for the service platform was eliminated.
The second section of Zeepipe I consists 30 inches (762 mm) pipeline from Draupner S to Sleipner. It links Zeepipe with Statpipe
.
The contract for pre-commissioning and commissioning of Zeepipe 1 was awarded to Halliburton Oilfield Services Inc.
Halliburton awarded engineering and procurement sub-contracts to Brown and Root Engineering Ltd. The pipeline was laid by Semac 1 and Castoro Sei
pipe-laying ships.

Zeepipe I
Thee Zeepipe I pipeline was commissioned on 1 October 1993. 814 kilometres (505.8 mi) long pipeline runs from Sleipner field to Zeebrugge. The pipeline has a diameter of with 40 inches (1,016 mm) and its capacity is 15 billion cubic meters of natural gas per year. At the time of construction, it was the longest and largest offshore pipeline in the world. It was more than twice as long as the next largest single-section offshore pipeline in the world.Originally, there was a plan to build a intermediate service platform to the pipeline to tie-in future compression facilities and to enable the pipeline to be pigged in two sections. However, due to technological development it is possible to serve the pipeline as one pigging
