Electric propulsion aids lifecraft operation
Torqeedo has developed a high-thrust electric propulsion system for VIKING's new LifeCraft survival craft.
The LifeCraft’s propulsion package consists of multiple, smaller motors for redundancy and manoeuvrability. Each craft has four Cruise 4.0 electric pod drives installed, powered by Power 24-3500 lithium-ion batteries in 48V banks.
One motor is installed at each corner of the boat and all are networked into an integrated energy monitoring system, giving the operator a clear view of motor and battery status at a glance.
LifeCraft has been successfully deployed and operated in heavy weather trials in the North Sea, using the Mermaid tanker. The trials demonstrated the flexibility of the craft to move rescue capacity to wherever it is most needed, said Torqeedo.
During the tests, witnessed and approved by DNV-GL, wave heights were between 3.6 and 4.6m with peaks up to 10m - 50% above the stipulated heavy weather testing requirements – and wind gusts up to 40 mph were recorded.
A 24-hour controlled drift test in battering seas was also carried out with no damage to the vessels.
Torqeedo is exhibiting at Seawork 2019 on stand PO63 and VIKING is exhibiting on stand PB125.
