Canadian towage company HaiSea Marine, a joint venture business formed by the Haisla Nation of British Columbia and local shipping line Seaspan, has taken delivery two new escort tugs.
The delivered tugs were designed by Vancouver-based naval architecture firm Robert Allan Ltd. One tug is the second in a series of LNG-fuelled vessels while the other tug is the third in another series of all-electric tugs.
As with earlier sister HaiSea Kermode, HaiSea Warrior boasts a dual-fuel propulsion system that runs on both LNG and diesel, making it one of the first LNG-fuelled tugs to be operated in Canada. It has a length of 40.2 metres, a moulded beam of 16 metres, a maximum draught of 7.1 metres, a moulded depth of six metres, a gross tonnage of 996, and a projected operational service life of 40 years.
The smaller HaiSea Brave is a sister of the earlier HaiSea Wamis. It has a length of 28.4 metres, a moulded beam of 13.4 metres, a moulded depth of 5.6 metres, a gross tonnage of 472, and a 5,288 kWh battery pack that drives two 2,600mm propellers to deliver a bollard pull of 70 tonnes.
Both tugs have secondary external firefighting capability and will be used primarily to escort gas carriers between the Pacific Ocean and LNG Canada's new export terminal in Kitimat, British Columbia.
