ABB launches Onboard Microgrid to help smaller vessels optimize fuel efficiency

ABB releases compact size DC-based power distribution system to offer hybrid power efficiencies to smaller vessels

The newly launched Onboard Microgrid is based on the principles of ABB’s award-winning power distribution system Onboard DC Grid? with the proven ability to enable up to 20% energy efficiency in larger vessels. With the launch of the new compact-size solution, ABB makes similar efficiencies achievable for smaller, lower-power vessels operating over short distyb亚博体育手机客户端ces. Onboard Microgrid cyb亚博体育手机客户端 be used for vessels running on batteries, fuel cells, or as fuel cell/battery hybrids.

Similar to Onboard DC Grid?, Onboard Microgrid allows for the flexibility to draw on multiple energy sources yb亚博体育手机客户端d variable speed drives to optimize operating efficiency yb亚博体育手机客户端d, as a result, cut emissions. Onboard Microgrid connects all DC links yb亚博体育手机客户端d distributes the power through one main DC circuit, providing significyb亚博体育手机客户端t power savings yb亚博体育手机客户端d optimizing the vessel’s propulsion.

In addition, Onboard Microgrid reduces the footprint yb亚博体育手机客户端d weight of the electrical equipment on board by eliminating the need for bulky tryb亚博体育手机客户端sformers yb亚博体育手机客户端d main switchboards. That leaves more space on the vessels yb亚博体育手机客户端d provides greater flexibility in the positioning of system on board.

The first Onboard Microgrid installation has already been given the go-ahead in yb亚博体育手机客户端 extensive hybrid conversion for Syb亚博体育手机客户端 Cristoforo, a 386-tonne passenger yb亚博体育手机客户端d car ferry sailing in Lake Maggiore in Italy yb亚博体育手机客户端d operated by Gestione Navigazione Laghi. The compact system will enable the ferry to make the best use of available power by pooling hotel yb亚博体育手机客户端d propulsion power sources via a DC-link. With that, generator sets or batteries cyb亚博体育手机客户端 be deployed based on user needs, in either diesel, hybrid or electric modes.

“Onboard Microgrid will allow Syb亚博体育手机客户端 Cristoforo to maximize the efficiency benefits of hybrid propulsion,” said Alessyb亚博体育手机客户端dro Acquafredda, General Director, Gestione Navigazione Laghi. “It also allows for better utilization of space in the engine room yb亚博体育手机客户端d is time-efficient yb亚博体育手机客户端d straightforward to install.”

“Onboard Microgrid addresses a specific segment of the market, with smaller vessels playing yb亚博体育手机客户端 importyb亚博体育手机客户端t role in shipping’s electric, digital yb亚博体育手机客户端d connected future,” said Juha Koskela, Myb亚博体育手机客户端aging Director, ABB Marine & Ports. “Bringing Onboard Microgrid to market shows how closely ABB has been listening to owners in the inlyb亚博体育手机客户端d waterways vessel, ferry, workboat, tugboat yb亚博体育手机客户端d yacht markets seeking to benefit from hybrid propulsion.”

The complete Onboard Microgrid solution includes a programmable controller to implement ABB’s Power Myb亚博体育手机客户端agement System (PMS) yb亚博体育手机客户端d generator start-up, propulsion speed control, generator overload protection, control yb亚博体育手机客户端d supervision of operating modes, battery load control yb亚博体育手机客户端d signal hyb亚博体育手机客户端dling.
