Pelagian was contracted to provide expert cable route engineering services for the planned installation of two 5km long power cables between the islands of Java and Bali in Indonesia.
Project work included the geospatial data management of detailed high resolution seabed bathymetry and associated seabed images to determine the location of the existing power cables and plan the routes of the new cables.
The routes proved to be very challenging, with steep rocky slopes reaching depths of 80 metres. The cables were planned to avoid suspensions and sharp rock outcrops so that they could be rock dumped after lay. Pelagian provided an expert analysis of potential cable spans to assist in the cable lay.
