Our work

Subsea is involved in a wide range of projects from salvage to environmental remediation. Below are some examples of projects we have completed.


Discovery of the SS Nemesis

Subsea is proud to have been involved in the discovery of the SS Nemesis, 120 years after it sank due to a huge storm.


Whilst undertaking a project to search for lost containers, using a remotely operated underwater vehicle (ROV) and a sonar, Subsea detected a large object on the sea bed and decided to investigate further.


It became apparent that the object was a shipwreck, and working together with the CSIRO and Heritage NSW, it was identified as the SS Nemesis.

Huge prop recovered

It’s no easy task dragging a bronze propeller tipping the scales at a massive 17.5 tonnes from the depths of the big blue.

Douglas Shoal remediation

When coal carrier Shen Neng 1 ran aground in April 2010, it caused extensive damage to Douglas Shoal. With an impact area of more than 40 hectares, the site bears the largest ship grounding scar known in the Great Barrier Reef Marine Park, and possibly the largest reef-related impact in the world.

Anchor recovery

Subsea were tasked with the search and recovery of an anchor worth $250k. It took about two months once approvals were received. It was like looking for a needle in a haystack.

18T Propellor salvage

Amongst other salvages including 2x 12T ship anchors, Subsea's task involved searching for the propellor using a Klein 3000 towfish. Once located, Subsea was tasked to carry out the successful salvage.
