During the last 10 years, the global market for luxury yachts has more than tripled. The average length overall of yachts being built is increasing, with the largest newbuild projects today exceeding 120 metres LOA. The demand for power increases with the size of the yachts and the technical solutions available facilitate features, which have long been appreciated by the major cruise liner operators.
For a yacht newbuild, ABB is capable of supplying the complete electrical Power and Propulsion system and Integrated Automation systems. Project management, system engineering, commissioning, sea trial assistance, and life-long system support are part of a typical ABB delivery package. Diesel-Electric Azipod Propulsion for Yachts
Diesel-electric Azipod propulsion – a well-proven standard among cruise liners, has become available for Yachts from 40 meters LOA to the largest Megayachts, with the introduction of the Azipod series.
The ABB installation for this yacht (not disclosed because of confidentiality reasons) covers the alternators for the 8 MTU main generator sets (each resiliently mounted on a frame), the main switchboard, a pair of 6 100 kW asynchronous propulsion motors with PWM (Pulse Width Modulated) control, together with integrated machinery automation and dynamic positioning. Each of the propulsion PWM switchboards is configured to control the tunnel thrusters through a common DC bus. Typical Configurations: Open an example by following the link on the right menu.
Any combination of the eight prime movers can be connected to the main switchboard in accordance with the prevailing need for power (propulsion + “hotel” load), as controlled by the Power Management system, which also protects the power plant from overload and black-outs. This will allow the diesel engines to operate at all times close to their optimum, resulting in low fuel consumption, longer overhaul intervals – and less NOx emissions.
In the event of a failing prime mover, another one can instantly be brought on line. The arrangement also allows service of a genset during voyage.
Operational safety is further enhanced through cross-connections from the main switchboard.
