Redwise has delivered the first full electric ASD tug on behalf of HaiSea Marine, a partnership of the Haisla Nation and Seaspan ULC, a long-standing customer of Redwise.

The tug, named Haisea Wamis, is the first of many. Not alone due to her unique electric propulsion, she it is the first in a series of five for HaiSea Marine: three electric-hybrid and two dual fuel escort tugs – to service LNG carriers at the LNG Canada’s new export facility in Kitimat, British Columbia.

The Robert Allen ElectRA 2800 design vessel built by SANMAR shipyard arrived well in time to be presented at the LNG 2023 convention at Vancouver.

The electric harbour tug measures 28.4m in length and boasts a battery capacity of 6.102 kWh, providing a bollard pull of 70 tonnes. The battery features enable Haisea Wamis to accomplish all its operations solely on battery power.

For the delivery voyage, a combination of the battery power and generator power was used in a hybrid mode to ensure sufficient range.

At the HaiSea Marine facility, the harbour tug can easily recharge from dedicated shore charging facilities situated at its berth in Kitimat in-between jobs.

The tug will operate with zero emissions, contributing to a more sustainable and environmentally friendly maritime industry and terminal operation.
