Aasen Shipping orders first hybrid self-discharging bulkers

The vessels are bulk carriers fitted with excavators for loading and unloading. By introducing hybrid power for the self-discharging bulkers and electric excavators, loading and discharging the cargo will be emission-free, using the onboard battery power and a shore power connection.

The hybrid installation will also offer wider fuel efficiencies, including peak shaving and propulsion and manoeuvring in port without the main engine.

Aasen Shipping contacted Wärtsilä to determine whether a hybrid installation would be beneficial for these new ships. Wärtsilä carried out a detailed study with Aasen Shipping, which concluded the extra initial investment required for the battery installation would be more than offset by the high level of achievable fuel cost savings. The shipowner estimates the installation will achieve annual fuel savings of 400t.

“We approached Wärtsilä because of their capabilities in delivering hybrid propulsion systems. We appreciate their support throughout the planning and design processes, which has resulted in the best possible solution for these vessels,” says Torbørn Torkelsen, CEO at Aasen Shipping.

Each ship will be fitted with a Wärtsilä 26 main engine with gearbox and controlled pitch propeller (CPP), a DC switchboard, a battery pack, and a power management system. The equipment is scheduled to be delivered to the yard commencing in mid-2021.
