The Switch to equip five VARD offshore vessels
Power electronics specialist The Switch will provide its DC-Hub technology to Vard Electro for five diesel-electric hybrid VARD 3 32 walk-to-work vessels. In total, Finland-based The Switch will supply 15 DC-hubs, according to a March 17 news release.
The new vessels will deliver maintenance, supply and operational services to offshore oil and gas platforms and will each be equipped with a diesel-electric and battery-hybrid propulsion system. The DC-Hubs will be designed to ensure a stable DC power supply in all sailing conditions and to accommodate integration of future energy sources.
Their main features are an electronic DC breaker, said to eliminate faults inside an inverter module, maintaining uninterrupted operation for the rest of the system; a DNV-approved electronic bus link, a DP3-rated device that isolates faults between DC-Hubs; and an electronic current limiter, providing protection against short-circuit faults toward the battery on the DC-Hub end of the cable.
