Underwater A-Bracket Bearing Repair
THE CLIENT
The Department of Defence is responsible for the readiness and operational capability of the Royal Australian Navy, including the maintenance and sustainment of its fleet. In support of this mission, the Navy sought an urgent solution to repair a critical component on one of its vessels without the availability of dry dock access.
BRIEF
The client engaged IKAD to address excessive wear in an A-bracket bearing, a key structural element supporting the vessel’s propeller shaft. With no dry dock access available and significant operational risk associated with delays, IKAD was tasked with developing and executing a first-of-class underwater repair solution.
PLANNING FOR SUCCESS
IKAD approached the challenge by assembling a dedicated engineering team to rapidly develop a custom underwater bearing changeover methodology. Early engagement with diving contractors and Navy stakeholders ensured alignment across safety, logistics, and operational priorities. The project was supported by in-house design and tooling teams, enabling IKAD to develop bespoke systems within a compressed timeframe.
OUR APPROACH
IKAD delivered a turnkey solution that included the design, engineering, and manufacture of bespoke underwater tooling; coordination with certified diving teams; and full project oversight throughout execution. Surface and underwater personnel were trained to work in tandem, ensuring seamless communication and operational control.
The initial repair was completed in just over one week. Its success validated the methodology, which has since been deployed across multiple international locations including Hawaii, Singapore, New Zealand, Guam, and throughout Australia.
WHAT THE CLIENT RECEIVED
The client received a fully operational, fit-for-purpose underwater repair solution that allowed the vessel to remain in service without dry-docking. This approach significantly reduced maintenance time, cost, and disruption to fleet schedules.
Beyond the initial repair, the Navy gained access to a repeatable, field-proven methodology that has since become part of their ongoing sustainment strategy. The solution also reduced safety and logistical risks by enabling critical repairs to be conducted at anchor or alongside, extending the interval between major dockings.
MOVING FORWARD
The success of the A-bracket bearing repair led to an enduring relationship between IKAD and the Department of Defence. IKAD’s solution has become a benchmark in marine maintenance innovation, offering long-term value through operational uptime, reduced maintenance costs, and strategic flexibility. For the client, it represents a trusted capability that supports mission readiness and vessel longevity in even the most demanding environments.
