Project Manager Mark Roberts, has commended everyone involved, saying, “We have been given this incredible opportunity to be involved in a project that could change the way the world understands renewable energy markets. Sun Cable have shown they are dynamic, ambitious and resourceful, turning challenges into new opportunities.

Our survey team delivered at every turn and have set the bar very high for the subsequent project phase. I could not be more impressed with the professionalism, resilience, technical competence and work ethic demonstrated by our team. I sincerely thank them for their efforts in delivering the first phase of work."

The Australian phase of the survey commenced on 25th August, with survey vessel Offshore Guardian mobilising in Darwin, NT. The work scope consisted of 35,448 man-hours of multibeam (MBES), side scan sonar, sub-bottom profiler data, cone penetration tests (CPT) and core samples. The project survey team then departed Darwin on the 19th November, concluding the 87 day operation. 

The delivery of the survey data is a milestone for Guardian Geomatics, and a significant step in the development of the unprecedented 3,750km HVDC cable proposed to run from Darwin to Singapore. The next phase of the survey, within Singaporean and Indonesian waters, is due to commence in Q1, 2021.
