Supplying and Integrating the Hybrid Electric Power & Propulsion System for New Zealand's Largest Vessel
HMNZS AOTEAROA, the largest vessel ever built for the Royal New Zealand Navy with a displacement of 26,000 tonnes, is now entering service. Her primary duties will be to provide global logistical support to her sovereign and coalition maritime, land and air units. From inception through to entry into service, Rolls-Royce has been intrinsically involved with the programme, specifically the vessel concept design and the hybrid electric propulsion system delivery.
HMNZS AOTEAROA's entry into service represents a significant and proud milestone for Rolls-Royce. In addition to the unique naval hull form design, Rolls-Royce had a pivotal role to play in the supply and integration of the advanced hybrid electric power and propulsion system.
Drawing from its world-leading range of power and propulsion equipment, this programme has become a showcase for Rolls-Royce's first naval hybrid electrical system.
The Rolls-Royce Power & Propulsion System arrangement is illustrated below.
The electrical power generation comprises four MTU 4000 Series diesel generators supplying the 690V main switchboards and controlled by the Electrical Power Management System. The switchboards distribute electrical power to the active front end drives for the propulsion motors and bow thruster, all of which are supplied and integrated by Rolls-Royce. The main propulsion engines also come from Rolls-Royce in the shape of two Bergen B33:45L9P engines.
Lee Skelton, Programme Manager has been responsible for coordinating the delivery of the programme for Rolls-Royce. Lee said, 'This has been one of the most exhilarating programmes I have worked on in my career. It has seen Rolls-Royce bring together suppliers both from inside and outside of Rolls-Royce, from across Europe and Asia, to deliver all the elements of this integrated solution.
'Just as we neared the end of the programme, the emergence of COVID-19 coincided with the final critical delivery phase. Whilst adding significant challenges, it didn't deter us from ensuring the delivery of an incredibly capable vessel, on time, which is every Programme Manager's ultimate ambition.
'I am certain that the experience we've gained from this programme can be positively leveraged to ensure that the on-going support from our local team will deliver additional benefits to HHI's EMD division in support of the FFX Batch II programme (Daegu-class frigates) where HHI-EMD has designed, manufactured and will provide some in-service support responsibilities for the specialised integrated enclosure for our MT30 marine gas turbine.
'Seeing HMNZS AOTEAROA enter service is a proud moment for many, including the Rolls-Royce team as we reflect on our significant contribution in bringing this ship to sea.
Looking to the future, as HMNZS AOTEAROA commences her operational service, there is a possibility that Rolls-Royce's involvement could continue in the form of providing through-life sustainment. Rolls-Royce Australia has extensive experience in providing sustainment services to naval customers throughout the region, particularly new vessels entering their operational phase.
'However, for now, on behalf of Rolls-Royce, I wish the crew of HMNZS AOTEAROA'fair winds and following seas' as they embark on their future operations.'
The original contract award to Rolls-Royce also included the supply of the Replenishment at Sea system, Steering Gear, Rudder, Kamewa Propellers and Bow Thruster. This equipment was transferred to Kongsberg following the sale of the Rolls-Royce Commercial Marine portfolio.
