The “SevenViking†is an underwater inspection, maintenance and repair (IMR) vessel. One of its main results and grading standards is its ability to perform safely on the high seas in the harsh North Sea and maintain its position during maintenance operations. stable.
     The IMR ship is powered by three double-reverse azimuth electric propellers each with a 3MW output. This propulsion system uses two 4,320 kW main diesel generators, two 1,824 kW main diesel generators, and a 250 kW emergency generator.
      The design and architecture of the "SevenViking" is designed to be environmentally sound and has been certified by the Norwegian Classification Society in accordance with its latest "CLEANDESIGN" level rules. The main generator engine incorporates an SCR catalyst to meet IMO Class III exhaust emission requirements.
     System application requirements
     This solution requires an intuitive one-touch automatic sequencing in the application design of four diesel generators and two bus couplers.
      The power management solution should also achieve excellent fuel savings and system safety with less generators running at full capacity: the "SevenViking" power system is divided into three separate operating systems and includes three sterns Three bow propulsion accelerators and three auxiliary systems. The three-way main switchboard ensures that the ship still has available propulsion power in the event of a single major failure.
DEIF 's turnkey power management solution must meet the DNVDYNPOS-AUTR (DP-2) grading requirements and support the "SevenViking" for safe and reliable DP operation at five meters high.
DEIF solution
DEIF 's Delomatic4 marine controller solution for the "SevenViking" includes DP-2 operation approved by the classification society with a closed busbar switch and compensated pressure drop with a special speed control interface in low load mode. Synchronous load distribution. To ensure safety, DEIF's solution implements special power-off prevention methods, including rapid propulsion and load shedding, and non-critical load group trips during overload. In order to achieve monitoring and control of multiple locations, the DEIF power management system is fully integrated into the ship's alarm and monitoring system.
      Operational one-button automatic sequencing is also deployed in solutions including SEMI-AUTO mode and PMS assisted mode of operation. The PMS-assisted operating mode used to optimize the engine includes the safe AUTO1.4 factory mode. This ensures that the minimum number of gensets is connected to the main bus, and the ECO operating sub-factory mode MAX1.4 ensures the maximum number of connections to the bus.
