The pipeline has a diameter of 40 inches (1,000 mm) and its capacity is 15 billion cubic meters of natural gas per year.
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.
[2] 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.[2] The pipeline was laid by Semac 1 and Castoro Sei pipe-laying ships.
