Siemens Closed Ring
Scenario for Fault ride through test (Short Circuit)
Helix Q5000 @ Jurong Shipyard in Singapore
• MV switchboards in closed ring operation, 4 split system
• 2 generators online
• 3 phase bolted short circuit of MV transformer breaker
• Hidden failure introduced in transformer breaker (DnV & USCG requirement)

Energy Storage – solutions proven in operations
Safety power back-up (8 vessels) Power to maintain position and operation until power is restored, or safely terminate operation despite in case of power loss
Peak Shaving Absorbs load peaks and load fluctuations to reduce the required available power and running engines
Performance boost (6 vessels) Instant power to absorb sudden load changes which reduce ramp time exposed by running engines. Allowing dynamic performance beyond that of combustion engines
Savings OPEX & CAPEX Improving fuel efficiency while also reducing running hours and wear and tear of equipment, provides savings in maintenance, overhauls and downtime. Reduced fuel, emissions taxes. May reduce number or rating of engines and thrusters
Improved environmental footprint Reduces fuel consumption and emissions
