Our work on the ASMD Upgrade Project for all 8 of the ANZAC Class frigates entailed all aspects of surface preservation and preparation. Our experienced workforce produced outstanding results in all areas including bilges/ballast/fuel tanks, habitable compartments, weather flight and hanger decks, machinery and artillery storage areas.
Throughout this work, Orontide was acknowledged for our ability to work in challenging environments and for our vigilance towards safety and environmental considerations whilst working effectively with other contractors.
We also provide services to other Commonwealth assets including the thermally sprayed sonar arrays and components for the Collins class submarines and various other submarine search and rescue vessels such as the MV Stoker.
Some examples of our work include:
HMAS Arunta ASMD Upgrade – During 2012-2013 Orontide undertook works on this activity over a period of 18 months. This project comprised a full strip of the Hull using Ultra High Pressure Water Jetting. Preservation works were carried out on areas including the Superstructure, weather decks, a variety of tanks and bilges, WC and bathrooms and decks. Up to 40 personnel worked on this project with manning levels fluctuating depending on access and work scopes underway.
HMAS Arunta SRA11 – Between February-May 2016 Orontide undertook works on this activity. Our team carried out a large number of internal tasks including a variety of Tanks and Bilges, WC and bathrooms and decks. External tasks included Flight deck, Forecastle Deck and the Flag Deck. A major challenge during this project was the inclement weather. This resulted in an increase of manpower on the project to ensure that the works were completed in the allotted timeframe. Another challenge was the containment of waste and debris while removing the coating from the external deck areas. This was achieved through careful planning and placement of encapsulation and a clean and uncompromised surface was achieved.
IMAV Project – Full strip of Flight and Hangar Decks conducted. Deck coating reinstated with application of non-skid coating. Coating repairs to the internal compartment and decks. Repairs include spot blasting and repairing deck head, bulkhead and decks to reinstate coatings by airless spraying and Brush rolling.
Collins Class Submarines – Orontide provided a specialised service with the application of Thermal Spray Aluminum to sonar and distributed array panels as well as the manufacturing of fenders.
Svitzer Australia – preservation contract carried out on Fremantle-based tug boat, the Svitzer Harrier, utilising high-reach equipment, mega blasters and airless spray equipment. The work involved the application of anti-corrosive primer, tie-coats, top coat and anti-fouling. With dry abrasive blast limited by environmental policies, 40,000 PSI water blasting was utilised to maintain schedule.
Mermaid Strait and Mermaid Sound offshore supply vessels – MMA Offshore
Work for two of MMA Offshore’s supply vessels, Mermaid Strait and Mermaid Sound, included abrasive blasting and coating application. The work was carried out on both vessels, currently chartered to Woodside Energy Limited, whilst they were docked for an IMO survey in Henderson.
The remediation works included application of PPG paints to both the external hulls above and below the waterline and superstructures. Both contracts were completed ahead of their allocated three-week schedule.
Ocean Warrior (Sea Sheppard Foundation) – AME Offshore Solutions
In preparation for its first visit to WA, the 50m custom built fast patrol ship spent some time in Henderson for a quick touch up before taking up residency in Fremantle.
Our Industrial Services team conducted mechanical preparation to remediate hull damage sustained during its launch from new build. This work included re-instating the new build paint system with full coat of antifouling to the underwater hull using International paints.
Mermaid Leeuwin offshore pipeline supply vessel – MMA Offshore
In March 2017, MMA Offshore engaged Orontide Industrial Services for preservation works to their Mermaid Leeuwin offshore pipeline supply vessel. The work included an application of full coat of PPG paints and antifouling to the entire underwater surface area including sea chests and thruster tunnels. The total area covered was 1900 sqm of the 75m long vessel. Antifouling and detailing of the vessel was carried out in two days with the work carried out to meet compliance for the Gorgon Project.
Westsea 11 Barge – MMA Offshore
Orontide was engaged in July by MMA Offshore to carry out preservation works on their 65m long Westsea 11 Barge. The work scope included abrasive spot and sweep blasting to the entire barge (3151 sqm) and repaint with new colour system using Jotun paints. Included in the contract was the new company logo for Austral Construction. The contract was completed in 16 days from start to finish including high pressure power wash to remove sea growth and contaminants.
