AI Technical Summary
Technical Problem
Ships connected to shore-based power grids in hazardous areas face the risk of arcing, which can lead to explosions due to the sealed deckhouse design, necessitating ventilation ducts that consume valuable space and pose structural risks.
Method used
A shore power connection system with ultra-fast earthing switches that can switch from open to closed state in less than 4 ms, grounding potential to prevent pressure buildup and eliminate the need for ventilation ducts, combined with a deckhouse design that maintains higher internal pressure to prevent gas ingress.
Benefits of technology
Prevents explosive pressure buildup by rapid earthing, ensuring safe operation without ventilation ducts and minimizing explosion risks, thus optimizing space utilization and safety.
