Ægir Divers was honored to assist the Victorian Maritime Centre with the hull and mooring inspection of the Submarine Ex HMAS ‘OTAMA’.

This vessel is currently moored in Westernport Bay with the intention to bring it ashore for display alongside other maritime memorabilia.

Core Sampling

Ægir Divers worked with BMT Scientific Marine Services to conduct core sampling from the seabeds of French Island and Hastings in Western Port Bay and Patterson River and Mordialloc Creek in Port Phillip.

Our commercial vessel ‘Torden’ utilized its onboard crane and capstan winch to allow scientists to launch & recover heavy coring equipment easily into position enabling a quick and effective sampling procedure. The forward deck acted as a very convenient workbench for measuring cores, sample collection and photo records.


BYS Wave Screen (2016 – 2017)

In 2016 Ægir Divers began the rebuild of the Eastern Wave Screen at Blairgowrie Marina on the Mornington Peninsula.

Approximately 250m of wave screen was replaced with cypress timbers, a Grade 2 Hardwood with a high resistance to Marine Borer (AS 5604). Each section of the wave screen removed was promptly replaced to negate both wave action and tidal flow, ensuring continued protection of the vessels within the marina.

Throughout the project, Ægir Divers worked closely with local recreational scuba business, ‘Dive2U’ in a combined effort affectionately dubbed ‘Operation: Sponge-Bob’. Prior to the removal of existing timber, dive teams relocated 1000’s of various sponges and ascidians and literally glued them onto the newly installed timbers. This project ensured the habitat was preserved for all of the marine life that call Blairgowrie Marina home.

Ægir Divers also recovered a section of the old wave screen which showed the diversity of marine life and this section is now on display in the Melbourne Sea Life Aquarium.


Commercial Aquatics – Swimming Pool Hydrostatic Inspections

Ægir Divers were commissioned by Commercial Aquatics to assist with in-water inspections to identify points of water loss from lining leaks or valve malfunction.

Hydrostatic tests were carried out on all pool systems and a pipe crawling robot was utilized to inspect the main balance tank piping.


Ramboll Environ – Biofoul Inspections

Ægir Divers were commissioned by Ramboll Environ to assist with the in-water inspection of biofouling activity of international shipping vessels.

Utilizing live video feed & still photographs, Ægir Divers have successfully completed multiple biofoul surveys at various ports in Port Phillip.

The project will help refine the Department of Agriculture and Water Resources (DAWR) understanding of the nature of biofouling risk approaching Australian shores.

This project will assist with the evaluation of future Commonwealth biofouling measures and allow for implementation of future biofoul management.
