CSJV was contracted by Chevron Australia Pty Ltd for the installation of the 20″ x 59.4 km long offshore Domgas pipeline from Barrow Island to mainland Australia for the Gorgon Project.

In order to achieve required permanent stability of the Domgas pipeline, a combination of pre/post pipelay trenching and rock bolting were deployed. OCS was contracted by CSJV to perform post pipelay trenching for specific sections which were carried out in two phases; trenching between KP18.200 to KP34.300 (with DWLB Java Constructor), and trenching between KP 48.414 to KP 57.014 (with SWLB Kalinda).
