Towage operator Kotug Canada said on Thursday that it is ordering the world’s first large, purpose-built high-bollard-pull tugs to be fueled with methanol.

Turkey’s Sanmar Shipyards has been entrusted with their construction, which is scheduled to be completed in time for the boats to be serviceable in 2025.

Kotug Canada, a partnership between Netherlands-based Kotug International and Canada’s Horizon Maritime Services, ordered the ships as part of a long-term contract with Trans Mountain’s Westridge Marine Terminal.
