Under the contract, Rolls-Royce will also supply
a wide range of equipment. A combined diesel electric and diesel (CODLAD)
propulsion system, with two Bergen main engines driving CP propellers
through a reduction gearbox. Four MTU high speed diesel gensets will
supply electricity for the vessel and other equipment that includes
bow thruster, the all-electric RAS/FAS system, other equipment includes
rotary vane steering gear with rudders and the propeller shafts.
Significantly larger than the ship it will replace, the electric RAS/FAS
system allows simpler and quieter replenishment/fuelling-at-sea operations
and will enable the tanker to refuel two ships at a time while underway.
It will also carry and refuel Defence Force helicopters, produce and
store water and transport bulk goods to bases in Antarctica during the
summer months.
“We see significant value in the Environship concept in the naval
sector”, says Sam Cameron, senior VP naval sales and business
development at Rolls-Royce. “Securing this milestone contract
for a naval application is important in showcasing our naval ship design
offering.
The 23,000 tonne tanker will carry out operations in extreme Antarctic
conditions and is strengthened and winterised to Polar code 6 requirements.
Used under licence the Rolls-Royce Environship concept design will be
built by prime contractor HHI as part of the New Zealand Defence Force’s
Maritime Sustainment Capability (MSC) project.
Working to an ambitious time-frame equipment will be delivered to the
South Korean builder from 2018, with vessel delivery scheduled for 2020.
